Pan Y, Xiao Y. Language and executive function in Mandarin-speaking deaf and hard-of-hearing children aged 3-5. JOURNAL OF DEAF STUDIES AND DEAF EDUCATION 2024:enae037. [PMID: 39277795 DOI: 10.1093/jdsade/enae037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 08/09/2024] [Accepted: 08/27/2024] [Indexed: 09/17/2024]
Abstract
The study aimed to explore spoken language and executive function (EF) characteristics in 3-5-year-old prelingually deaf and hard-of-hearing (DHH) children, and evaluate the impact of demographic variables and EF on spoken language skills. 48 DHH children and 48 typically developing children who use auditory-oral communication were recruited. All participants underwent EF tests, including auditory working memory (WM), inhibitory control, cognitive flexibility, and the EF performance reported by parents. Using Mandarin Clinical Evaluation of Language for Preschoolers (MCELP), vocabulary comprehension, sentence comprehension, vocabulary naming, sentence structure imitation, and story narration were evaluated only in the DHH group, and their results were compared with the typical developmental level provided by MCELP. Results showed that DHH children exhibit deficiencies in different spoken language domains and EF components. While the spoken language skills of DHH children tend to improve as they age, a growing proportion of individuals fail to reach the typical developmental level. The spoken language ability in DHH children was positively correlated with age and EFs, and negatively correlated with aided hearing threshold, while auditory WM could positively predict their spoken language performance.

Abstract
PURPOSE The analysis of different language domains and exploration of variables that affect the outcomes of cochlear implantation would help to document the efficacy of cochlear implantation and intervention programs. The aim of this work was to examine the language profile of children with Cochlear Implants (CI) and to assess the effect of age at the time of cochlear implantation and the impact of duration of rehabilitation on the development of linguistic abilities for cochlear implanted children. METHODS The study was conducted on 46 Arabic speaking children using unilateral CI who are receiving regular post-cochlear auditory and language rehabilitation in the phoniatrics unit, Kasr Alaini hospital. A Proficient Preschooler Language Evaluation (APPEL TOOL) was applied for the assessment of different language domains. RESULTS Children who received post implant rehabilitation for ≥ 2 years showed significant improvement in all subtests' scores of APPEL tool than children who received same rehabilitation for ≤ 1 year. There was no significant difference of language scores between children who have received CI before age of 3 years and those who have been implanted after age of 3 years. CONCLUSION This study showed that the language profile of CI children was beneficially affected by the longer duration of therapy post implantation.

Abstract
PURPOSE This study investigated irony comprehension by Mandarin-speaking children with cochlear implants, focusing on how prosodic and visual cues contribute to their comprehension, and whether second-order Theory of Mind is required for using these cues. METHOD We tested 52 Mandarin-speaking children with cochlear implants (aged 3-7 years) and 52 age- and gender-matched children with normal hearing. All children completed a Theory of Mind test and a story comprehension test. Ironic stories were presented in three conditions, each providing different cues: (a) context-only, (b) context and prosody, and (c) context, prosody, and visual cues. Comparisons were conducted on the accuracy of story understanding across the three conditions to examine the role of prosodic and visual cues. RESULTS The results showed that, compared to the context-only condition, the additional prosodic and visual cues both improved the accuracy of irony comprehension for children with cochlear implants, similar to their normal-hearing peers. Furthermore, such improvements were observed for all children, regardless of whether they passed the second-order Theory of Mind test or not. CONCLUSIONS This study is the first to demonstrate the benefits of prosodic and visual cues in irony comprehension, without reliance on second-order Theory of Mind, for Mandarin-speaking children with cochlear implants. It implies potential insights for utilizing prosodic and visual cues in intervention strategies to promote irony comprehension.

Narrative skills and language comprehension in preschool children with cochlear implants: A comparison with children with Developmental Language Disorder or typical development. JOURNAL OF COMMUNICATION DISORDERS 2024; 109:106424. [PMID: 38579544 DOI: 10.1016/j.jcomdis.2024.106424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 02/21/2024] [Accepted: 03/25/2024] [Indexed: 04/07/2024]
Abstract
INTRODUCTION The narrative skills of children with cochlear implants (CIs) are fragile, but the factors at play and whether these difficulties could be similar to those detected in language impairment are not clear. The present study aims to assess, at the microstructural level, narrative skills, comparing children with CIs with children with Developmental Language Disorder (DLD) or Typical Development (TD). Furthermore, the relationship between verbal (lexical and morphosyntactic) comprehension and narrative skills across groups is investigated. METHODS The narratives of 19 children with CIs (Mage = 62.42 months, SD = 6.83), 13 children with DLD (Mage = 65.38 months, SD = 4.27), and 18 preschool children with TD (Mage = 63.67 months, SD = 4.31) were assessed in a standardized task. Articles, prepositions, pronouns, gender and number agreement, accuracy in the use of verbs, and number of arguments in each sentence were analysed. Lexical and morphosyntactic comprehension were also assessed. Performance was compared across groups using ANOVAs or Kruskal-Wallis tests. The role of lexical and morphosyntactic comprehension in predicting each morphological and syntactic element in the narrative task was examined using linear regressions. RESULTS Data analysis showed that both children with CIs and DLD had fragilities in narration, both in the morphological and syntactic components. Although some differences between children with CIs and those with DLD emerged in descriptive analyses, these were not statistically significant. Regressions showed that morphosyntactic comprehension predicted the number of pronouns produced only in the TD group. CONCLUSIONS The scarce differences between CI and DLD groups and the absence of an effect of morphosyntactic comprehension on pronoun production may be due to their low production of these elements in the narrative task and/or to a difficulty in managing pronouns in an expressive task regardless of their ability to comprehend them. Potential implications of these results are discussed.

Delayed auditory experience results in past tense production difficulties and working memory deficits in children with cochlear implants: A comparison with children with developmental language disorder. Neuropsychologia 2024; 196:108817. [PMID: 38355036 DOI: 10.1016/j.neuropsychologia.2024.108817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 02/01/2024] [Accepted: 02/05/2024] [Indexed: 02/16/2024]
Abstract
Extent evidence has shown that morphosyntax is one of the most challenging linguistic areas for children with atypical early language experiences. Over the last couple of years, comparisons between deaf children with CIs and children with DLD have gained interest - as cases of atypical early language experiences, including, but not restricted to, delayed onset of exposure to language input and language-processing difficulties. Evidence suggests that the morphosyntactic difficulties experienced by deaf children with CIs and children with DLD are very similar in nature. However, the few studies that have directly compared both groups are inconclusive, with deaf children with CIs either performing significantly better or on par with children with DLD. These differences in findings can be attributed, in part at least, to a failure to implement essential methodological controls - even more so given that deaf children with CIs comprise a very diverse population. The goal of the present study was to directly compare the performance of deaf children with CIs to that of children with DLD on a morphosyntactic ability known to be particularly difficult for both groups. Specifically, the present study conducted a detailed examination of the past tense marking abilities of deaf children with CIs and children with DLD while controlling for factors specific to deaf children with CIs, for children's basic cognitive abilities as well as for children's age, sex assigned at birth, and SES. Past tense verbs are particularly relevant as they are used as a marker of developmental language disorder (DLD) in children learning French. Moreover, extent evidence shows that deaf children with CIs and children with DLD have important WM difficulties, but also that there is an association between auditory perception, processing abilities, and working memory (WM) abilities as well as with the acquisition of morphological features, including tense marking. Unfortunately, no study has examined the relation between the accurate production of past tense verbs and WM abilities in children with CIs and children with DLD learning French. Fifteen deaf children with CIs between 5 and 7 years of age were compared to 15 children with DLD and to 15 typically-developing monolingual controls (MON), matched on important variables, using a past tense elicitation task as well as measures of phonological and nonverbal WM abilities. The results confirm that the deaf children with CIs and the children with DLD both performed significantly lower than the MON controls on the past tense elicitation task - suggesting that difficulties with past tense verbs in French might not only be a marker of DLD but, instead, a correlate of atypical language acquisition. Of importance, the present study is the first to show that deaf children with CIs perform significantly lower than children with DLD on a past tense elicitation task - highlighting the importance of using methodological controls. As well, significant correlations were found between the performance of the deaf children with CIs and of the children with DLD on the past tense elicitation task and their phonological and nonverbal WM abilities. Taken together with previous studies conducted in the same populations, this represents another evidence suggesting that early atypical language experiences result in language and WM deficits, including morphosyntactic difficulties.

Abstract
PURPOSE Our goal is to understand how the different types of plural marking are understood and processed by children with cochlear implants (CIs): (a) how does salience affect the processing of plural marking, (b) how is this processing affected by the incomplete signal provided by the CIs, and (c) is it linked to individual factors such as chronological age, vocabulary development, and phonological working memory? METHOD Sixteen children with CIs and 30 age-matched children with normal hearing (NH) participated in an eye-tracking study. Their task was to choose the corresponding picture to an auditorily presented singular or plural noun. Accuracy, reaction time, and gaze fixation were measured and analyzed with mixed-effect models. RESULTS Group differences were found in accuracy but not in reaction time or gaze fixation. Plural processing is qualitatively similar in children with CIs and children with NH, with more difficulties in processing plurals involving stem-vowel changes and less with those involving suffixes. Age effects indicate that processing abilities still evolve between 5 and 11 years, and processing is further linked to lexical development. CONCLUSIONS Our results indicate that early implantation seems to be beneficial for the acquisition of plural as indicated by very small between-group differences in processing and comprehension. Processing is furthermore affected by the type of material (i.e., phonetic, phonological, or morphological) used to mark plural and less so by their segmental salience. Our study emphasizes the need to take into account the form of the linguistic material in future investigations at higher levels of processing.

Abstract
BACKGROUND Early literacy development is critical for children with hearing loss to develop literacy skills in the years to come. The aim of this study is to compare the early literacy skills of 60-72 months' children with hearing loss to the results of children with normal hearing. METHODS A total of 40 children (20 children with hearing aid (HA) and 20 children with normal hearing (NH) were evaluated in the study. Receptive and expressive language was assessed by Test of Early Language Development (TELD-3) and Early Literacy Test (EROT) was applied to assess the early literacy skills of all children in the study. RESULTS The receptive and expressive language results of the hearing-impaired group were significantly lower than those of normal hearing. Moreover, in EROT when a general analysis is made with main test titles such as, the vocabulary knowledge, letter knowledge, the listening comprehension, results showed that there was a significant difference between the HA and NH groups. CONCLUSIONS This study highlights the importance of supporting early literacy skills, which are prerequisite skills for reading and writing skills, in children who receive both mainstreaming education and special education in the risk group and/or continue their education in kindergarten.

Le Normand MT, Thai-Van H. Early grammar-building in French-speaking deaf children with cochlear implants: A follow-up corpus study. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023.

Abstract
BACKGROUND One of the most consistent findings reported in the paediatric cochlear implant (CI) literature is the heterogeneity of language performance observed more in grammatical morphology than in lexicon or pragmatics. As most of the corpus studies addressing these issues have been conducted in English, it is unclear whether their results can be generalized to other languages. In particular, little is known about languages known for their grammatical complexity, such as French. AIMS The aim of this corpus study was to compare the productive use of function words (FWs) and some agreement features (AGRs) in children with CIs and children with typical development (TD) matched for mean length of utterance in words (MLUwords ), a general index of grammatical complexity, and auditory experience, as measured by hearing age (HA) and chronological age (CA), respectively. METHODS & PROCEDURES Natural speech samples from 116 monolingual French-speaking children, including 40 children with CIs followed longitudinally and 76 TD children, were collected. FWs and AGRs were analysed using a Part of Speech Tagger (POS-T) from the Child Language Data Exchange System (CHILDES). OUTCOMES & RESULTS The two groups differed by 3 years for HA and CA. No effect of family socio-economic status (SES) was found in the CI group. Stepwise regression analyses showed that the two groups did not share the same predictors of MLUwords : plurals and determiners predicted MLUwords in children with CIs, at 2 and 3 years of HA, whereas feminine markers and subject-pronouns were found to best predict MLUwords in TD children at 2 and 3 years of CA. Structural equation models (SEMs), a combination of confirmatory factor analysis (CFA) and path analysis, yielded a different hierarchical structure of grammatical relations (GRs). Selective difficulties affecting verbal clitics and other pronominal forms were found specifically in the CI group (object-pronouns, reflexive, relative and past participles). Dependency grammar analysis confirmed these contrasting developmental profiles in multiword utterances, such as preposition/nouns, subject/verbs, and verb/determiner/nouns. CONCLUSIONS & IMPLICATIONS Atypical grammatical patterns in children with CIs reflect a specific architecture of syntactic dependencies of FWs underpinning morphological complexity and syntactic connectivity. Clinical implications are discussed for assessment and intervention planning. WHAT THIS PAPER ADDS What is already known on this subject The productive use of FWs has been identified as a particular area of weakness in children with CIs compared with TD children. In addition, heterogenous grammatical performance has often been found after 1-3 years of CI use, regardless of demographic factors such as age at implantation, duration of deafness or SES. What this paper adds to existing knowledge Assessing the early building of FWs and AGRs in children with CIs helps to understand the syntactic complexity and hierarchical structure of their language. Since most corpus studies on grammatical morphology have been conducted in English, it is not clear whether their difficulties can be generalized to other languages. The French language has a system of FWs and inflections that determine the morphophonological properties of nominal and verbal forms. Early grammar learning in children with CIs born with profound deafness were compared with the two groups of TD children matched both for duration of auditory experience (i.e., HA of CI children, CA of TD children) and for MLUwords . We found a similar profile between groups at 2 years but not at 3 years for HA and CA. The two groups do not share the same predictors of MLUwords : namely, plurals and determiners for CI children versus feminine markers and subject pronouns for TD children. They show a different syntactic organization of GRs. Children with CIs struggle with selective difficulties affecting verbal clitics and pronominal forms (object-pronouns, reflexive, relative and past participles). Consistent with theories of morphophonological richness and syntactic connectivity, our results support the distributional learning hypothesis of language acquisition that infants and toddlers are sensitive to FWs and AGRs at an early age. Specific components of syntactic organization are disrupted in children with CIs. What are the potential or actual clinical implications of this work? This work has potential clinical implications because it unravels the limitations of morphophonological processing in children with CIs. Its results highlight a specific difficulty in learning FWs and AGRs in a verbal inflectional morphology context.

Abstract
PURPOSE This study examined the extent to which prelingual cochlear implant (CI) users show a slowed speaking rate compared with typical-hearing (TH) talkers when repeating various speech stimuli and whether the slowed speech of CI users relates to their immediate verbal memory. METHOD Participants included 10 prelingually deaf teenagers who received CIs before the age of 5 years and 10 age-matched TH teenagers. Participants repeated nonword syllable strings, word strings, and center-embedded sentences, with conditions balanced for syllable length and metrical structure. Participants' digit span forward and backward scores were collected to measure immediate verbal memory. Speaking rate data were analyzed using a mixed-design, repeated-measures analysis of variance, and the relationships between speaking rate and digit spans were evaluated by Pearson correlation. RESULTS Participants with CIs spoke more slowly than their TH peers during the sentence repetition task but not in the nonword string and word string repetition tasks. For the CI group, significant correlations emerged between speaking rate and digit span scores (both forward and backward) for the sentence repetition task but not for the nonword string or word string repetition task. For the TH group, no significant correlations were found. CONCLUSIONS The findings indicate a relation between slowed speech production, reduced immediate verbal memory, and diminished language capabilities of prelingual CI users, particularly for syntactic processing. These results support theories claiming that immediate memory, including components of a central executive, influences the speaking rate of these talkers. Implications for therapies designed to increase speech fluency in CI recipients are discussed. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.21644795.

Abstract
Auditory brainstem implantation (ABI) is a relative recent development in paediatric hearing restoration. Consequently, young-implanted children's productive language has not received much attention. This study investigated speech intelligibility of children with ABI (N = 3) in comparison to children with cochlear implants (CI) and children with typical hearing (TH). Spontaneous speech samples were recorded from children representing the three groups matched on cumulative vocabulary level. Untrained listeners (N = 101) rated the intelligibility of one-word utterances on a continuous scale and transcribed each utterance. The rating task yielded a numerical score between 0 and 100, and similarities and differences between the listeners' transcriptions were captured by a relative entropy score. The speech intelligibility of children with CI and children with TH was similar. Speech intelligibility of children with ABI was well below that of the children with CI and TH. But whereas one child with ABI's intelligibility approached that of the control groups with increasing lexicon size, the intelligibility of the two other children with ABI did not develop in a similar direction. Overall, speech intelligibility was only moderate in the three groups of children, with quite low ratings and considerable differences in the listeners' transcriptions, resulting in high relative entropy scores.

Abstract
OBJECTIVES The vocabulary of children with cochlear implants is often smaller than that of their peers with typical hearing, but there is uncertainty regarding the extent of the differences and potential risks and protective factors. Some studies indicate that their receptive vocabulary develops well at first, but that they fail to keep up with their typical hearing peers, causing many CI users to enter school with a receptive vocabulary that is not age-appropriate. To better understand the receptive vocabulary abilities of children with cochlear implants this study explored age-related differences to matched children with typical hearing and associations between vocabulary skills and child-level characteristics. DESIGN A retrospective cross-sectional study with matched controls was conducted at the Norwegian national cochlear implant center at Oslo University Hospital. Eighty-eight children (mean age 8.7 years; range 3.2 to 15.9; 43 girls, 45 boys) who had received bilateral cochlear implants before 3 years of age were compared with two groups of children with typical hearing. One group was matched for maternal education, sex, and chronological age, the other group was matched for maternal education, sex, and hearing age. Receptive vocabulary performance was measured with the British Picture Vocabulary Scale. RESULTS Cochlear implant users' receptive vocabulary was poorer than that of age-matched children with typical hearing ( M = 84.6 standard points, SD = 21.1; children with typical hearing: M = 102.1 standard points, SD = 15.8; mean difference -17.5 standard points, 95% CI [-23.0 to -12.0], p < 0.001; Hedges's g = -0.94, 95% CI [-1.24 to -0.62]), and children with cochlear implants were significantly more likely to perform below the normative range (risk ratio = 2.2, 95% CI [1.42 to 3.83]). However, there was a significant nonlinear U-shaped effect of age on the scores of cochlear implant users, with the difference to the matched typical hearing children being largest (23.9 standard points, on average) around 8.7 years of age and smaller toward the beginning and end of the age range. There was no significant difference compared with children with typical hearing when differences in auditory experience were accounted for. Variability was not significantly different between the groups. Further analysis with a random forest revealed that, in addition to chronological age and hearing age, simultaneous versus sequential implantation, communication mode at school, and social integration were predictors of cochlear implant users' receptive vocabulary. CONCLUSIONS On average, the receptive vocabulary of children with cochlear implants was smaller than that of their typical hearing peers. The magnitude of the difference was changing with age and was the largest for children in early primary school. The nonlinear effect of age might explain some of the ambiguity in previous research findings and could indicate that better intervention is required around school entry. The results emphasize that continuous monitoring and support are crucial to avoid far-reaching negative effects on the children's development and well-being.

[PMID: 35219037 DOI: 10.1016/j.ijporl.2022.111086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 02/01/2022] [Accepted: 02/15/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Age of cochlear implantation (CI) is an important predictor of language development in those with congenital sensorineural hearing loss. Despite universal newborn hearing screening initiatives and the known benefits of early CI, a subset of congenitally deaf children continue to be evaluated for cochlear implants later in childhood. This study aims to identify the barriers to early cochlear implantation in these children. METHODS A retrospective review was conducted for all pediatric cochlear implants aged 3 years or older performed at a single academic institution between 2013 and 2017. Children implanted before the age three, those with a prior unilateral cochlear implant, and those with progressive or sudden hearing loss were excluded. Variables included newborn hearing screen results, age at hearing loss diagnosis, time of initiation and documented benefit of hearing aids, age of implantation, pre/post-implantation evaluation scores, and reason for delayed referral for cochlear implantation. RESULTS Thirty-one patients were identified meeting these inclusion criteria. Twenty-one children were subject to UNBS in the U.S. Fourteen of those children failed their newborn hearing screening. Average age at implantation was 6.2 years. Four reasons were identified for increased age at cochlear implantation. Two categories represent delays related to (1) Amplification continually prescribed even though the range of hearing loss and speech development assessment suggests CI may have been more appropriate well before referral (N = 13) (2) Patients were not subject to newborn hearing screening and/or timely diagnosis of their hearing loss (N = 8). In other cases, patients were appropriately fit with hearing aids until evidence that they derived limited benefit and then referred for CI (N = 8). Lastly, in a few cases, records were indeterminate with regards to the timing and appropriate diagnosis of their hearing loss (N = 2). CONCLUSION Understanding the reasons for delayed cochlear implantation in congenitally deaf children might allow the development of targeted interventions to improve outcomes. Specifically, those children who were not referred before age 3 despite use of amplification with limited benefit offer one potential target population for earlier CI.

Variability in Quantity and Quality of Early Linguistic Experience in Children With Cochlear Implants: Evidence from Analysis of Natural Auditory Environments. Ear Hear 2022; 43:685-698.

Abstract
OBJECTIVES Understanding how quantity and quality of language input vary across children with cochlear implants (CIs) is important for explaining sources of large individual differences in language outcomes of this at-risk pediatric population. Studies have mostly focused either on intervention-related, device-related, and/or patient-related factors, or relied on data from parental reports and laboratory-based speech corpus to unravel factors explaining individual differences in language outcomes among children with CIs. However, little is known about the extent to which children with CIs differ in quantity and quality of language input they experience in their natural linguistic environments. To address this knowledge gap, the present study analyzed the quantity and quality of language input to early-implanted children (age of implantation <23 mo) during the first year after implantation. DESIGN Day-long Language ENvironment Analysis (LENA) recordings, derived from home environments of 14 early-implanted children, were analyzed to estimate numbers of words per day, type-token ratio (TTR), and mean length of utterance in morphemes (MLUm) in adults' speech. Properties of language input were analyzed across these three dimensions to examine how input in home environments varied across children with CIs in quantity, defined as number of words, and quality, defined as whether speech was child-directed or overheard. RESULTS Our per-day estimates demonstrated that children with CIs were highly variable in the number of total words (mean ± SD = 25,134 ± 9,267 words) and high-quality child-directed words (mean ± SD = 10,817 ± 7,187 words) they experienced in a day in their home environments during the first year after implantation. The results also showed that the patterns of variability across children in quantity and quality of language input changes depending on whether the speech was child-directed or overheard. Children also experienced highly different environments in terms of lexical diversity (as measured by TTR) and morphosyntactic complexity (as measured by MLUm) of language input. The results demonstrated that children with CIs varied substantially in the quantity and quality of language input experienced in their home environments. More importantly, individual children experienced highly variable amounts of high-quality, child-directed speech, which may drive variability in language outcomes across children with CIs. CONCLUSIONS Analyzing early language input in natural, linguistic environments of children with CIs showed that the quantity and quality of early linguistic input vary substantially across individual children with CIs. This substantial individual variability suggests that the quantity and quality of early linguistic input are potential sources of individual differences in outcomes of children with CIs and warrant further investigation to determine the effects of this variability on outcomes.

Abstract
Increase in the auditory abilities of children with cochlear implants (CIs) has led to an improvement in naming tasks, although divergent results are still being reported; this strongly suggests that further studies are needed. The study aims to compare the responses in a picture-naming activity between the complete population of children aged 5 to 7 with cochlear implants in Catalonia -Spain- (N = 31), without developmental problems, and a matched sample of 31 children with typical hearing. A picture-naming task was used to assess their lexical naming abilities. The results show that children with CIs provide more non-responses, they produce fewer words correctly, they require a longer reaction time and they commit more picture-naming errors than children with typical hearing. The auditory age does significantly affect the results, but not the type of implant. In spite of the hearing gain achieved with the cochlear implant and the listening experience progressively achieved in distinct contexts, further explicit work on lexical naming in speech-therapy intervention is clearly required.

Abstract
Purpose To extend our knowledge about factors influencing early vocabulary development for infants with cochlear implants (CIs), we investigated the impact of positive parenting behaviors (PPBs) from the Indicator of Parent Child Interaction, used in parent-child interactions during everyday activities. Method Implantation age for the sample recruited from CI clinics in Australia ranged from 6 to 10 months for 22 children and from 11 to 21 months for 11 children. Three observation sessions at three monthly intervals were coded for use of PPBs. Children's productive vocabulary, based on the MacArthur-Bates Communicative Development Inventories parent checklist, was collected approximately 6 and 9 months later. A repeated-measures negative binomial generalized linear mixed-effects model was used to investigate associations between the total PPBs per session, covariates (maternal education, gender, and time since implant), and the number of words produced. In follow-up analyses with the PPBs entered separately, variable selection was used to retain only those deemed informative, based on the Akaike information criterion. Results As early as Session 1, associations between the PPBs and vocabulary were identified. Time since implant had a positive effect. For different sessions, specific PPBs (descriptive language, follows child's lead, and acceptance and warmth) were identified as important contributors. Conclusions Complementing previous findings, valuable information was identified about parenting behaviors that are likely to impact positively the early vocabulary of infants with CIs. Of importance is providing parents with information and training in skills that have the potential to help create optimal contexts for promoting their child's early vocabulary development.

Abstract
Many children who use cochlear implants (CI) have strong skills in many aspects of spoken language; however, limited information is available about their mastery of the pragmatic skills required to participate in conversation. This study reviewed published literature describing the pragmatic skills of children who use CIs in conversational contexts. Twenty-five studies met the inclusion criteria, and data were extracted describing participant characteristics, methodology, data type, outcomes, and factors associated with outcomes. Pragmatic skills were described in three broad categories: speech acts, turns, and breakdowns and repairs. Participants showed heterogeneity in age, age at implantation, duration of implant use, and languages used. Studies employed a variety of methodologies, used a range of different sample types and coding strategies, and considered different factors associated that might be associated with children's pragmatic skills. Across studies, children with CIs were reported to have a range of pragmatic skills in conversational contexts, from few to severe difficulties. The body of literature on this topic is small and considered heterogeneous children with CIs with a wide range of skills. Further research is needed to understand the pragmatics language skills of children with CIs and the factors influencing the diversity in skills observed.

Abstract
Studies have shown that children vary in the trajectories of their language development after cochlear implant (CI) activation. The aim of the present study is to assess the preverbal and lexical development of a group of 20 Italian-speaking children observed longitudinally before CI activation and at three, 6 and 12 months after CI surgery (mean age at the first session: 17.5 months; SD: 8.3; and range: 10–35). The group of children with CIs (G-CI) was compared with two groups of normally-hearing (NH) children, one age-matched (G-NHA; mean age at the first session: 17.4 months; SD: 8.0; and range: 10–34) and one language-matched (G-NHL; n = 20; mean age at the first session: 11.2 months; SD: 0.4; and range: 11–12). The spontaneous interactions between children and their mothers during free-play were transcribed. Preverbal babbling production and first words were considered for each child. Data analysis showed significant differences in babbling and word production between groups, with a lower production of words in children with CIs compared to the G-NHA group and a higher production of babbling compared to the G-NHL children. Word production 1 year after activation was significantly lower for the children with CIs than for language-matched children only when maternal education was controlled for. Furthermore, latent class growth analysis showed that children with CIs belonged mainly to classes that exhibited a low level of initial production but also progressive increases over time. Babbling production had a statistically significant effect on lexical growth but not on class membership, and only for groups showing slower and constant increases. Results highlight the importance of preverbal vocal patterns for later lexical development and may support families and speech therapists in the early identification of risk and protective factors for language delay in children with CIs.

Abstract
Recently, a phonemic-based tactile speech communication system was developed with the goal to transmit speech through the skin for people with hearing impairments and those whose auditory and visual channels are overloaded or compromised. The display, called the TActile Phonemic Sleeve (TAPS), consisted of a 4-by-6 tactor array worn on the dorsal and volar surfaces of the forearm. Earlier work showed that people were able to learn the haptic symbols for 39 English phonemes and reach a mean phoneme recognition rate of 86% correct within one to four hours of training. The current research evaluated the acquisition of up to 500 words using TAPS. A total of 51 participants were trained and tested in three studies with increasing number of phonemes and vocabulary sizes. Individual achievements varied, but the results clearly demonstrate the potential of transmitting any English word using TAPS within a reasonable period of learning. Future work will include increasing the speech transmission rate with TAPS by improving the phonemic codes and reducing the inter-phoneme intervals, addressing the reception of words and sentences composed of strings of tactile phonemes, and assessing the performance of TAPS as a speech communication system for people with severe hearing impairments.

Abstract
INTRODUCTION Using the United States Food and Drug Administration (FDA) as example, we argue that regulatory agencies worldwide should review their guidance on cochlear implants (CIs). METHODS This is a position paper, thus the methods are strictly argumentation. Here we give the motivation for our recommendation. The FDA's original approval of implantation in prelingually deaf children was granted without full benefit of information on language acquisition, on childcaregiver communication, and on the lived experience of being deaf. The CI clinical trials, accordingly, did not address risks of linguistic deprivation, especially when the caregiver's communication is not fully accessible to the prelingually deaf child. Wide variability in the effectiveness of CIs since initial and updated approval has been indicated but has not led to new guidance. Children need to be exposed frequently and regularly to accessible natural language while their brains are still plastic enough to become fluent in any language. For the youngest infants, who are not yet producing anything that could be called language although they might be producing salient social signals (Goldstein et al. Child Dev 80:636-644, 2009), good comprehension of communication from caregiver to infant is critical to the development of language. Sign languages are accessible natural languages that, because they are visual, allow full immersion for deaf infants, and they supply the necessary support for this comprehension. The main language contributor to health outcomes is this combination of natural visual language and comprehension in communication. Accordingly, in order to prevent possible language deprivation, all prelingually deaf children should be exposed to both sign and spoken languages when their auditory status is detected, with sign language being critical during infancy and early childhood. Additionally, all caregivers should be given support to learn a sign language if it is new to them so that they can comprehend their deaf children's language expressions fully. However, both languages should be made accessible in their own right, not combined in a simultaneous or total communication approach since speaking one language and signing the other at the same time is problematic. RESULTS Again, because this is a position paper, our results are our recommendations. We call for the FDA (and similar agencies in other countries) to review its approval of cochlear implantation in prelingually deaf children who are within the sensitive period for language acquisition. In the meantime, the FDA should require manufacturers to add a highlighted warning to the effect that results with CI vary widely and CIs should not be relied upon to provide adequate auditory input for complete language development in all deaf children. Recent best information on users' experience with CIs (including abandonment) should be clearly provided so that informed decisions can be made. The FDA should require manufacturers' guidance and information materials to include encouragement to parents of deaf children to offer auditory input of a spoken language and visual input of a sign language and to have their child followed closely from birth by developmental specialists in language and cognition. In this way parents can align with providers to prioritize cognitive development and language access in both audio-vocal and visuo-gestural modalities. DISCUSSION The arguments and recommendations in this paper are discussed at length as they come up.

Abstract
When children start formal education, they are expected to be able to express complex thoughts. However, in order to do so, they need to be able to use both complex grammatical structures and a variety of words. One group that is at risk of having a delay in terms of their expressive language ability is children with cochlear implants (CI). In this study, we evaluated whether children with CI perform comparably to children with typical hearing (TH) on a standard expressive spoken grammar and a standard expressive spoken vocabulary task when the groups were matched on non-verbal intelligence and working memory capacity. It was found that the children with CI in this study performed more poorly on a standard expressive spoken vocabulary task but not on a standard expressive spoken grammar task when compared to the children with TH. Differences in terms of expressive spoken vocabulary do not seem to be explained by differences in cognitive ability. In addition, the variation in terms of expressive spoken language ability was larger in the children with CI compared to the children with TH. This might be explained by additional confounding factors, like the time of language deprivation or by a greater influence of cognitive differences for the acquisition of spoken language for children with CI.

Abstract
For children with normal hearing (NH), early communication skills predict vocabulary, a precursor to grammar. Growth in early communication skills of infants with cochlear implants (CIs) was investigated using the Early Communication Indicator (ECI), a play-based observation measure. Multilevel linear growth modelling on data from six ECI sessions held at three-monthly intervals revealed significant growth overall, with a non-significant slower growth rate than that of children with NH (comparison age centred at 18 months). Analyses of gesture use and of nonword vocalisations revealed the CI group used significantly more of each, with more rapid growth. In contrast, the CI group used significantly fewer single words and multiword utterances, and with slower growth. Maternal education and time to achieve consistent CI use impacted significantly on growth for the CI sample. The results indicate that progression to vocabulary by young CI users can be supported by encouraging their use of prelinguistic communication.

Abstract
BACKGROUND Cochlear implanted (CI) children have problems in most aspects of language and in particular with regards to grammar. Considering the lack of studies in the field of grammar treatment in CI children and bearing in the mind that CI children have the potential to develop language, the aim of the present study was to investigate the effect of treating grammar in CI children using a treatment grammar program. METHODOLOGY first, the literature related to grammar were reviewed so as to extract different grammatical components for developing grammar treatment program and to make sentences for each element as well as to compile a manual for its implementation. Second, the validity of the sentences was examined using the Delphi method. Third, grammar treatment was performed on five CI children. Persian Developmental Sentence Scoring(PDSS) and Mean Length of Utterance(MLU) were used to evaluate them before and after treatment. RESULTS Five grammatical classes were extracted, and the grammatical elements were classified in each category according to age. For all of the grammatical items, 2076 sentences were constructed. After applying the Delphi method, a total of 1936 sentences with Kendall's coefficient of concordance (W) of 71%, remained. Using this program, grammar treatment was effective in all five children. The PDSS and MLU increased in all five children during the treatment phase, which was confirmed by Percentage of Non-overlapping Data (PND), Improvement Rate Difference (IRD). During the follow-up period, the children showed that they were able to maintain the trained components. CONCLUSION Cochlear implants have the potential to learn language skills, and the present study confirms their ability to learn grammar, using a comprehensive grammar treatment program.

Is the spontaneous speech of 7-year-old cochlear implanted children as intelligible as that of their normally hearing peers? Int J Pediatr Otorhinolaryngol 2020; 133:109956. [PMID: 32097774 DOI: 10.1016/j.ijporl.2020.109956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 01/09/2020] [Accepted: 02/13/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVES Studies on speech intelligibility usually focus on either individual words, sentences or longer sequences of speech. Since these different kinds of speech samples can be judged using different methodologies, a difference in the reported intelligibility scores can either be due to the difference in the type of sample or methodology. The present study compares the speech intelligibility of seven-year-old children with a cochlear implant (CI) with that of their normally hearing (NH) peers. The first aim is to compare the intelligibility of short sentences and longer sequences of speech using the same methodology. Secondly, it has been suggested that i.a. advances in CI technology and changes in candidacy criteria may have had a positive influence on the intelligibility of children with CI. In order to assess this issue, the intelligibility of seven-year-olds implanted ten years apart will be compared. METHOD The speech of two cohorts of early implanted children with CI (n = 16) and NH peers (n = 16), matched on several criteria but implanted in different years, was collected. More specifically, short and longer samples were selected from recordings of a wordless picture book retelling. Both types of samples were judged on a visual analogue scale by 105 inexperienced listeners. RESULTS The results showed that the intelligibility of children with CI was lower than that of their NH peers. Moreover, longer samples were significantly more intelligible than short samples for both groups. No significant effect was found between the two cohorts of children with CI. However, the intelligibility of three out of four children with CI was found to be on a par with that of their NH peers, indicating a large amount of variability between subjects. CONCLUSION Listeners ascribed higher intelligibility to longer samples than to short samples, despite the fact that both types were extracted from the same recordings and listeners followed the same judgement procedure. The amount of context thus facilitated speech decoding. No effect of the calendar year of implantation was found, suggesting that e.g., the evolution in CI technology did not have a significant impact on CI users' intelligibility after six years of device use.

Abstract
We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children's language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom communication: a spoken-only group (n = 101), a sign-only group (n = 131), and a bimodal group (n = 104). Overall, children showed delays in language and reading compared to norms established for hearing children. For language, vocabulary standard scores were higher than for English syntax. Although delayed in language, children made expected gains based on hearing norms from kindergarten to second grade. Reading scores declined from kindergarten to second grade. Spoken-only and bimodal children had similar word reading and reading comprehension abilities and higher scores than sign-only children. Spoken-only children had better spoken phonological awareness and nonword reading skills than the other two groups. The sign-only and bimodal groups made similar and significant gains in ASL syntax and fingerspelling phonological awareness.

Abstract
OBJECTIVES The present study aims to assess the emotional experiences, specifically parenting stress, of mothers of children with cochlear implants (CIs), and their children's language development before surgery and at three and six months after CI activation. METHODS Twenty mothers of children with CIs were interviewed before their children's surgery about their experiences in connection with the diagnosis of deafness, the surgery and the activation of the CI. The Parenting Stress Index questionnaire and the MacArthur-Bates-Communication Development Inventory were administered before the surgery and at 3 and 6 months after the CI activation. RESULTS Analysis of the qualitative data resulting from the interviews showed that the mothers' emotional experiences before the CI surgery were complex. Mothers reported both positive and negative emotions related to deafness, diagnosis and surgery, benefits of the CI, coping strategies and future expectations. The mothers of children with more advanced lexical production six months after CI activation displayed a high frequency of themes related to positive emotions, thoughts and coping strategies before the surgery. Distress on the part of the mothers, perceptions of difficulties in their child and instances of parent-child dysfunctional interaction were negatively and significantly related to the child's language and communication development. CONCLUSIONS The findings support the importance of assessing the mother's emotional experience in relation to diagnosis and CI activation before the surgery. IMPLICATIONS FOR CLINICAL PRACTICE ARE DISCUSSED: specifically, the importance of the support offered to the parents, aimed at enhancing both their awareness of their expectations about their child's rehabilitation process and their self-efficacy in supporting the child's adaptation to the use of the CI.

Abstract
Purpose The increasing prevalence of pediatric cochlear implantation over the past 25 years has left little doubt that resulting improvements in hearing offer significant benefits to language development for many deaf children. Furthermore, given the documented importance of access to language from birth, there has been strong support for providing congenitally deaf children with implants as early as possible. Earliest implantation, in many ways, has become the "gold standard" in pediatric cochlear implantation, on the assumption that it is the key to language development similar to that of hearing children. Empirical evidence to support this assumption, however, appears more equivocal than generally is believed. This article reviews recent research aimed at assessing the impact of age at implantation on vocabulary and grammatical development among young implant users. Method Articles published between 2003 and 2018 that included age at implantation as a variable of interest and in which it was subjected to statistical analysis were considered. Effect sizes were calculated whenever possible; we conducted a multivariate meta-analysis to compare outcomes in different language domains. Results Taken together, findings from 49 studies suggest that age at implantation is just one of a host of variables that influence vocabulary and grammatical development, its impact varying with several factors including whether age at implantation is treated as a dichotomous or continuous variable. Results from a meta-analysis showed significant differences across language domains. Conclusion The pattern of results obtained indicates the importance of considering various child, family, and environmental characteristics in future research aimed at determining how early "early implantation" needs to be and the extent to which age at implantation, duration of implant use, and other factors influence language and language-related outcomes.

Abstract
This case study analyzes and describes the language, executive function, and psychosocial outcomes of two 6-year-old children with cochlear implants in the context of their respective family environments. Despite having nearly identical audiological histories, their language abilities and social skills are markedly different from one another, exemplifying the variability in outcomes of children with cochlear implants. Families play a critical role in child development. Including analyses of the family environment serves to draw attention to the importance of expanding the variables of potential influence beyond child characteristics to more fully encompass the factors that influence children's performance in future studies.

Abstract
Purpose This systematic review summarizes the evidence for differences in the amount of language input between children with and without hearing loss (HL). Of interest to this review is evaluating the associations between language input and language outcomes (receptive and expressive) in children with HL in order to enhance insight regarding what oral language input is associated with good communication outcomes. Method A systematic review was conducted using keywords in 3 electronic databases: Scopus, PubMed, and Google Scholar. Keywords were related to language input, language outcomes, and HL. Titles and abstracts were screened independently, and full-text manuscripts meeting inclusion criteria were extracted. An appraisal checklist was used to evaluate the methodological quality of studies as poor, good, or excellent. Results After removing duplicates, 1,545 study results were extracted, with 27 eligible for full-text review. After the appraisal, 8 studies were included in this systematic review. Differences in the amount of language input between children with and without HL were noted. Conversational exchanges, open-ended questions, expansions, recast, and parallel talk were positively associated with stronger receptive and expressive language scores. The quality of evidence was not assessed as excellent for any of the included studies. Conclusions This systematic review reveals low-level evidence from 8 studies that specific language inputs (amount and style) are optimal for oral language outcomes in children with HL. Limitations were identified as sample selection bias, lack of information on control of confounders and assessment protocols, and limited duration of observation/recordings. Future research should address these limitations.

Abstract
Purpose Age at cochlear implantation frequently is assumed to be a key predictor of pediatric implantation benefits, but outcomes related to learning and cognition appear inconsistent. This critical assessment examines relevant literature in an effort to evaluate the impact of age at implantation in those domains for individuals who received their devices as children. Method We examined 44 peer-reviewed articles from 2003 to 2018 considering age at implantation and conducted statistical analyses regarding its impact on several domains, including literacy, academic achievement, memory, and theory of mind. Results Across 167 assessments in various experiments and conditions, only 21% of the analyses related to age at implantation yielded evidence in favor of earlier implantation, providing greater benefits to academic achievement, learning, or cognition compared to implantation later in childhood. Among studies that considered cognitive processing (e.g., executive function, memory, visual-spatial functioning), over twice as many analyses indicated significant benefits of earlier implantation when it was considered as a discrete rather than a continuous variable. Conclusion Findings raise methodological, practical, and theoretical questions concerning how "early" is defined in studies concerning early cochlear implantation, the impact of confounding factors, and the use of nonstandard outcome measures. The present results and convergent findings from other studies are discussed in terms of the larger range of variables that need to be considered in evaluating the benefits of cochlear implantation and question the utility of considering age at implantation as a "gold standard" with regard to evaluating long-term outcomes of the procedure as a medical treatment/intervention for hearing loss.

Abstract
This paper investigates the use of checklists to assess pragmatics in children and adolescents who are deaf and hard of hearing. A systematic literature review was undertaken to identify all of the published research articles between 1979 and 2018 on the topic of the assessment of pragmatics for this population of children and adolescents. The 67 papers identified in this review were analyzed and all papers that utilized a checklist to assess pragmatic skills were identified. Across the 18 different published papers on the use of pragmatic skills among children who are deaf and hard of hearing, nine checklists were identified. These nine checklists were then compared and contrasted on six key features including identification of a theoretical framework or model; the type of pragmatic skills measured; the age range of the child assessed; the information/outputs generated; the primary informant for the assessment; and reliability, validity, and normative data. The resulting analysis provides a comprehensive guide to aid clinicians, educators, and researchers in selecting an appropriate checklist to assess pragmatic skills for children and adolescents who are deaf and hard of hearing.

Abstract
OBJECTIVES This study had two key objectives. First, to examine whether children who receive cochlear implants (CIs) before the age of 3 years and who are experienced implant users (mean length of CI use = 6 years; range = 4 to 9 years) show deficits on a word learning task relative to their hearing peers. Second, to examine whether variation in age at implantation within the first 3 years of life relates to later word learning abilities. DESIGN Twenty-one 6- to 10-year-old children with CIs, 21 chronological age-matched (AM) hearing children, and 21 vocabulary-matched hearing children completed an auditory word learning task in which they were required to learn the names of eight rare animals. Comprehension and production probes tested their learning of these unfamiliar words. RESULTS The children with CIs performed similarly to AM peers on the comprehension phase of the word learning task. Their production performance was significantly poorer than the AM group but was in line with that of their younger vocabulary-matched hearing peers. Differences between the CI and AM groups were accounted for by differences between the groups in terms of their existing vocabulary knowledge. Within the CI group, there was no evidence of an association between age at implantation and performance on the word learning task, but existing vocabulary size showed strong positive correlations with word learning performance, after adjustment for chronological age. CONCLUSIONS When implanted by the age of 3 years, and with over 4 years CI experience, 6- to 10-year-old children are able to perform similarly to their AM hearing peers in terms of their comprehension of newly learned words. Producing accurate phonological forms of newly learned words may be a more challenging task for children with CIs, but their production performance is consistent with their vocabulary size. This cross-sectional study provides support for a relationship between existing vocabulary size and novel word learning skills in children with CIs; future longitudinal studies should test the hypothesis that this relationship is developmentally reciprocal.

Abstract
Purpose The purpose of this study was to investigate the processing of morphosyntactic cues (case and verb agreement) by children with cochlear implants (CIs) in German which-questions, where interpretation depends on these morphosyntactic cues. The aim was to examine whether children with CIs who perceive the different cues also make use of them in speech comprehension and processing in the same way as children with normal hearing (NH). Method Thirty-three children with CIs (age 7;01-12;04 years;months, M = 9;07, bilaterally implanted before age 3;3) and 36 children with NH (age 7;05-10;09 years, M = 9;01) received a picture selection task with eye tracking to test their comprehension of subject, object, and passive which-questions. Two screening tasks tested their auditory discrimination of case morphology and their perception and comprehension of subject-verb agreement. Results Children with CIs who performed well on the screening tests still showed more difficulty on the comprehension of object questions than children with NH, whereas they comprehended subject questions and passive questions equally well as children with NH. There was large interindividual variability within the CI group. The gaze patterns of children with NH showed reanalysis effects for object questions disambiguated later in the sentence by verb agreement, but not for object questions disambiguated by case at the first noun phrase. The gaze patterns of children with CIs showed reanalysis effects even for object questions disambiguated at the first noun phrase. Conclusions Even when children with CIs perceive case and subject-verb agreement, their ability to use these cues for offline comprehension and online processing still lags behind normal development, which is reflected in lower performance rates and longer processing times. Individual variability within the CI group can partly be explained by working memory and hearing age. Supplemental Material https://doi.org/10.23641/asha.7728731.

Abstract
Auditory brainstem implants (ABI) are recently being used to restore hearing of children with a congenital hearing loss, due to for instance the absence of auditory nerves. Thus far, the literature has focused on perceptual outcomes. The present study is among the first ones to investigate the spoken language development after implantation. The lexical development of children with ABI is examined longitudinally in comparison to children with typical hearing and children with cochlear implants. Results show that children with ABI still have smaller spoken vocabularies as compared to (hearing) age-matched children with cochlear implants and children with typical hearing. Implications will be discussed.

Abstract
BACKGROUND Language outcomes for children with cochlear implants (CIs) vary widely, even for those implanted before 2 years of age. Identifying the main influencing factors that account for some of the variability is important in order to provide information to guide appropriate clinical and intervention services for young children with CIs. However, there is limited research focusing on the predictors of early vocabulary development for children implanted in infancy. AIMS To identify significant predictors of vocabulary (12-15 months post-implant) for a sample of 33 children with CIs, the majority implanted between 6 and 10 months of age, drawing on predictors of vocabulary reported for children with normal hearing. Of particular interest was the impact of pre-implant development and use of gestures. METHODS & PROCEDURES Children with severe to profound hearing loss, and no other known disabilities, were recruited from CI clinics in Australia before receiving their CIs. Subscales from the Bayley Scales-III (receptive and expressive communication, gross and fine motor, and cognition) were used to assess their development at that time. Using the Macarthur-Bates Communicative Development Inventory (Words and Gestures) we documented the children's (1) use of gestures at six data-collection times 3 months apart; and (2) vocabulary at the last three time points. Time since implant and time to consistent use of the CIs were also included as potential predictors. Data were analysed using generalized linear models, assuming a negative binomial response with a log-link function. Stepwise variables selection was followed to retain a smaller number of the covariates. OUTCOMES & RESULTS A year after implantation, the significant predictors identified for vocabulary were pre-implant receptive communication and early gesture use. Together with fine motor and cognitive skills, these two variables were also significant predictors of vocabulary 3 months later. With maternal education entered into the models, higher vocabulary scores were significantly associated with higher maternal education 12 months post-implantation, but not 15 months. CONCLUSIONS & IMPLICATIONS Pre-implant abilities are important in explaining some variability in the early vocabulary of infants with CIs, together with their use of early gestures post-implantation. That is, having a non-verbal means to express a concept can assist in their development of oral vocabulary. Identifying strategies to help develop fine motor skills for infants with CIs, and encouraging their use of gestures to communicate their needs/intentions, are likely to be of benefit.

[PMID: 29625430 PMCID: PMC6105123 DOI: 10.1044/2018_ajslp-16-0164] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 05/30/2017] [Accepted: 12/17/2017] [Indexed: 05/29/2023]
Abstract
PURPOSE This study sought to expand understanding of the impact of cochlear implantation on grammatical acquisition by comparing young children who have vocabularies of comparable size. Two research questions were investigated: (a) Do young cochlear implant (CI) recipients have grammatical skills comparable to those of children with normal hearing (NH) matched by spoken vocabulary size? (b) Do these groups show associations between vocabulary size and grammatical measures? METHOD The participants included 13 CI recipients at 24 months postactivation (chronological ages = 33-60 months; M = 44.62) and 13 children with NH between 27 and 30 months old (M = 20.69). The 2 groups were matched by their vocabulary size. Four grammatical outcomes were analyzed from the MacArthur Communicative Development Inventory (Fenson, Marchman, Thal, Dale, & Reznick, 2007) and 20-min language samples: (a) grammatical complexity, (b) mean length of utterances, (c) tense marker total, and (d) productivity scores. RESULTS The 2 groups showed comparable grammatical skills across the 4 measures. Consistently significant associations between vocabulary size and grammatical outcomes were found in the CI group, with fewer associations in the NH group. CONCLUSIONS The 2 groups showed similar grammatical abilities. The young CI recipients appeared to be following a typical pattern of linguistic development.

Communication dynamics between mothers and their children with cochlear implants: Effects of maternal support for language production. JOURNAL OF COMMUNICATION DISORDERS 2018; 73:1-14.

Abstract
This study examined (a) the functions and modalities of maternal and child communication during interaction between mothers and children with cochlear implants (CIs), comparing them with mothers and normally hearing (NH) children, and (b) the effectiveness of maternal support strategies in eliciting adequate answers in children with CI. Twenty preschoolers with CIs (M = 40 months) and 40 NH children - 20 matched by chronological age (CANH, M = 40 months) and 20 matched by hearing age (HANH, M = 25 months) - were videotaped during shared book reading and toy play with their mothers. Child and maternal utterances were coded for communicative functions and modalities (vocal, gestural, bimodal), including gesture types; maternal repairs were examined for type of support provided, and child answers for adequacy. Mothers in the CI group and in the CANH group displayed higher proportions of Informative Repairs than mothers of HANH children. However, unlike the mothers of NH children, mothers of children with CIs used bimodal utterances significantly more than vocal utterances. Sequential analysis revealed that maternal Informative Repairs elicited the production of Adequate Answers in both children with CIs and CANH. Interestingly, in the CI group this association was found only when Informative Repairs were accompanied by gestures. These findings offer suggestions for intervention programs focused on parent-child conversation.

Abstract
OBJECTIVES To determine whether relative delays among domains exist in the conversational use of vocabulary, syntax, and morphology by children with cochlear implants (CIs) and whether these were differentially affected by age of implantation (AOI) and the audibility of speech. METHODS Participants in this short-term longitudinal study were 126 children with AOI of 6-38 months and a matched group of 30 children without hearing loss. Language samples of the same children at ages 3.5 and 4.5 were analyzed for the breadth of vocabulary and bound morphemes used, and sentence length. RESULTS At both test ages, expressive language domains were delayed equally. Higher performance across domains was independently associated with younger AOI and better pre-implant-aided thresholds. No domain was affected differently by very early implantation, but bound morpheme breadth was associated with better CI-aided thresholds. Between 63 and 78% of children with AOI of 6-11 months scored close to hearing age-mates by 4.5, a level achieved by fewer than 25% of those with AOI of 19-24 months or later ages. DISCUSSION Previous studies indicated greater language delays in the areas of morphology and syntax than those of vocabulary, with the earliest ages of implantation conferring the greatest benefit to those domains. The current design addressed inconsistency across studies in modes of communication used, presence/absence of other disabilities, and differences in language domains chosen as outcome measures. CONCLUSIONS Linguistic domains benefitted equally from early implantation, regardless of the duration of auditory stimulation. Better pre-CI-aided hearing often compensated for later AOI. Bound morpheme use was greater with better CI-aided thresholds.

Abstract
In child cochlear implant (CI) users, early implantation generally results in highly intelligible speech. However, for some children developing a high level of speech intelligibility may be problematic. Studies of speech production in CI users have principally been based on perceptual judgment and acoustic measures. Articulatory measures, such as those collected using ultrasound provide the opportunity to more precisely evaluate what makes child CI users more intelligible. This study investigates speech production and intelligibility in children with CI using acoustic and articulatory measures. Ten children with unilateral or bilateral CIs and 13 children with normal hearing (NH) participated in the study. Participants repeated five English vowels (/a/, /e/, /i/, /o/, /u/) with and without auditory feedback. Ultrasound was used to capture tongue positions and acoustic signals were recorded simultaneously. The results showed that, despite quite similar acoustic results, the two speaker groups made different use of the tongue to implement vowel contrasts. Indeed, the tongue position was lower in the feedback OFF condition than the feedback ON condition for all participants, but the magnitude of this difference was larger for CI users than for their NH peers. This difference led to diminished intelligibility scores for CI users. This study shows the limitation of acoustic measurements alone and demonstrates how the use of articulatory measurements can explain intelligibility patterns. Moreover, our results show that when cochlear implantation occurs early in life and auditory feedback is available, CI users' intelligibility is comparable to that of their NH peers.

Abstract
A long-standing belief is that sign language interferes with spoken language development in deaf children, despite a chronic lack of evidence supporting this belief. This deserves discussion as poor life outcomes continue to be seen in the deaf population. This commentary synthesizes research outcomes with signing and non-signing children and highlights fully accessible language as a protective factor for healthy development. Brain changes associated with language deprivation may be misrepresented as sign language interfering with spoken language outcomes of cochlear implants. This may lead to professionals and organizations advocating for preventing sign language exposure before implantation and spreading misinformation. The existence of one-time-sensitive-language acquisition window means a strong possibility of permanent brain changes when spoken language is not fully accessible to the deaf child and sign language exposure is delayed, as is often standard practice. There is no empirical evidence for the harm of sign language exposure but there is some evidence for its benefits, and there is growing evidence that lack of language access has negative implications. This includes cognitive delays, mental health difficulties, lower quality of life, higher trauma, and limited health literacy. Claims of cochlear implant- and spoken language-only approaches being more effective than sign language-inclusive approaches are not empirically supported. Cochlear implants are an unreliable standalone first-language intervention for deaf children. Priorities of deaf child development should focus on healthy growth of all developmental domains through a fully-accessible first language foundation such as sign language, rather than auditory deprivation and speech skills.

Abstract
PURPOSE There is a need to better understand the epidemiological relationship between language development and psychiatric symptomatology. Language development can be particularly impacted by social factors-as seen in the developmental choices made for deaf children, which can create language deprivation. A possible mental health syndrome may be present in deaf patients with severe language deprivation. METHODS Electronic databases were searched to identify publications focusing on language development and mental health in the deaf population. Screening of relevant publications narrowed the search results to 35 publications. RESULTS Although there is very limited empirical evidence, there appears to be suggestions of a mental health syndrome by clinicians working with deaf patients. Possible features include language dysfluency, fund of knowledge deficits, and disruptions in thinking, mood, and/or behavior. CONCLUSION The clinical specialty of deaf mental health appears to be struggling with a clinically observed phenomenon that has yet to be empirically investigated and defined within the DSM. Descriptions of patients within the clinical setting suggest a language deprivation syndrome. Language development experiences have an epidemiological relationship with psychiatric outcomes in deaf people. This requires more empirical attention and has implications for other populations with behavioral health disparities as well.

Abstract
OBJECTIVES Previous research has suggested the use of rhythmic structures (implemented in musical material) to improve linguistic structure processing (i.e., syntax processing), in particular for populations showing deficits in syntax and temporal processing (e.g., children with developmental language disorders). The present study proposes a long-term training program to improve syntax processing in children with cochlear implants, a population showing syntax processing deficits in perception and production. METHODS The training program consisted of morphosyntactic training exercises (based on speech processing) that were primed by musical regular primes (8 sessions) or neutral baseline primes (environmental sounds) (8 sessions). A crossover design was used to train 10 deaf children with cochlear implants. Performance in grammatical processing, non-word repetition, attention and memory was assessed before and after training. RESULTS Training increased performance for syntax comprehension after both prime types but for grammaticality judgements and non-word repetition only when musical primes were used during training. For the far-transfer tests, some effects were also observed for attention tasks, especially if fast and precise sequential analysis (sequencing) was required, but not for memory tasks. CONCLUSIONS The findings extend the previously observed beneficial short-term effects of regular musical primes in the laboratory to long-term training effects. Results suggest that the musical primes improved the processing of the syntactic training material, thus enhancing the training effects on grammatical processing as well as phonological processing and sequencing of speech signals. The findings can be interpreted within the dynamic attending theory (postulating the modulation of attention over time) and associated oscillatory brain activity. Furthermore, the findings encourage the use of rhythmic structures (even in non-verbal materials) in language training programs and outline perspectives for rehabilitation.

Abstract
OBJECTIVES To analyse language development of children with a cochlear implant (CI) in relation to length of CI use and age at implantation and to examine the suitability of the TEDIL as an assessment tool for measuring early language development in Turkish children. METHODS A total of 119 children implanted with a CI before 5 years of age were assessed acutely on sound field thresholds, speech recognition thresholds, open-set and closed-set monosyllabic word tests, the TEDIL, categories of auditory performance (CAP), and speech intelligibility rating (SIR). The outcome scores were analysed in relation to length of CI use (3, 4, and 5 years) and age at implantation (<24 months vs. >24 months). The TEDIL scores were compared to all other outcome measures. RESULTS Scores significantly increased with CI experience. CAP and SIR were significantly higher in the younger implanted group. No significant difference was observed between the younger and older implanted group on the closed-set and open-set monosyllabic tests and the TEDIL. The TEDIL scores significantly correlated with CAP, SIR, and the closed-set and open-set word scores. The mean TEDIL standard score was close to average. CONCLUSIONS Performance of CI users improves with increased CI experience. CI users implanted <24 months tend to have better auditory skills and clearer speech than CI users implanted >24 months. CI users implanted between 24 months and 60 months tend to develop language similarly to CI users implanted <24 months. The TEDIL is a suitable tool for assessing early receptive and expressive language development in Turkish children.

Abstract
BACKGROUND The aim of this study was to analyze how the reading process of deaf Spanish elementary school students is affected both by those components that explain reading comprehension according to the Simple View of Reading model: decoding and linguistic comprehension (both lexical and grammatical) and by other variables that are external to the reading process: the type of assistive technology used, the age at which it is implanted or fitted, the participant's socioeconomic status and school stage. DESIGN Forty-seven students aged between 6 and 13 years participated in the study; all presented with profound or severe prelingual bilateral deafness, and all used digital hearing aids or cochlear implants. Students' text comprehension skills, decoding skills and oral comprehension skills (both lexical and grammatical) were evaluated. RESULTS Logistic regression analysis indicated that neither the type of assistive technology, age at time of fitting or activation, socioeconomic status, nor school stage could predict the presence or absence of difficulties in text comprehension. Furthermore, logistic regression analysis indicated that neither decoding skills, nor lexical age could predict competency in text comprehension; however, grammatical age could explain 41% of the variance. Probing deeper into the effect of grammatical understanding, logistic regression analysis indicated that a participant's understanding of reversible passive object-verb-subject sentences and reversible predicative subject-verb-object sentences accounted for 38% of the variance in text comprehension. CONCLUSIONS Based on these results, we suggest that it might be beneficial to devise and evaluate interventions that focus specifically on grammatical comprehension.

Abstract
Fricative production is affected in children with cochlear implants (CI) as compared to age-matched normally hearing (NH) children. However, the phonological development of children with CI is rarely compared to that of NH peers matched on lexicon size. We compare the early word initial fricative development of 10 children with CI and 30 NH children matched on lexicon size and on chronological age. Children with CI are expected to differ from their NH peers when they are matched on chronological age. But, are lexical development and phonological development commensurate in children with CI as they have been shown to be in NH children? Results show that fricative production in children with CI deviates from that of age-matched NH peers. The differences between both groups disappear when they were matched on lexicon size. Thus, phonological development in children with CI is similar to that of their NH peers with comparable lexicon sizes.

Abstract
BACKGROUND The spoken language difficulties of children with moderate or severe to profound hearing loss are mainly related to limited auditory speech perception. However, degraded or filtered auditory input as evidenced in children with cochlear implants (CIs) may result in less efficient or slower language processing as well. To provide insight into the underlying nature of the spoken language difficulties in children with CIs, linguistic profiles of children with CIs are compared with those of hard-of-hearing (HoH) children with conventional hearing aids and children with specific language impairment (SLI). AIMS To examine differences in linguistic abilities and profiles of children with CIs as compared with HoH children and children with SLI, and whether the spoken language difficulties of children with CIs mainly lie in limited auditory perception or in language processing problems. METHODS & PROCEDURE Differences in linguistic abilities and differential linguistic profiles of 47 children with CI, 66 HoH children with moderate to severe hearing loss, and 127 children with SLI are compared, divided into two age cohorts. Standardized Dutch tests were administered. Factor analyses and cluster analyses were conducted to find homogeneous linguistic profiles of the children. OUTCOMES & RESULTS The children with CIs were outperformed by their HoH peers and peers with SLI on most linguistic abilities. Concerning the linguistic profiles, the largest group of children with CIs and HoH children shared similar profiles. The profiles observed for most of the children with SLI were different from those of their peers with hearing loss in both age cohorts. CONCLUSIONS & IMPLICATIONS Results suggest that the underlying nature of spoken language problems in most children with CIs manifests in limited auditory perception instead of language processing difficulties. However, there appears to be a subgroup of children with CIs whose linguistic profiles resemble those of children with SLI.

Abstract
The aim of the present study was to analyze the relative influence of age at implantation, parental expansions, and child language internal factors on grammatical progress in children with cochlear implants (CI). Data analyses used two longitudinal corpora of spontaneous speech samples, one with twenty-two and one with twenty-six children, implanted between 0;6 and 3;10. Analyses were performed on the combined and separate samples. Regression analyses indicate that early child MLU is the strongest predictor of child MLU two and two-and-a-half years later, followed by parental expansions and age at implantation. Associations between earliest MLU gains and MLU two years later point to stability of individual differences. Early type and token frequencies of determiners predict MLU two years later more strongly than early frequency of lexical words. We conclude that features of CI children's very early language have considerable predictive value for later language outcomes.
