Relative clause reading in hearing impairment: different profiles of syntactic impairment

The Acquisition of a Diglossic Language by Deaf and Hard of Hearing Students: Evidence From a Sentence Production Task

PURPOSE

The current study aimed to examine morphosyntactic errors in sentences produced by DHH students, who are signers of Israeli Sign Language, and also users of Palestinian Colloquial Arabic (PCA) and written Modern Standard Arabic (MSA).

METHOD

Nineteen school-age DHH students participated in a sentence elicitation task in which they retold events portrayed in 24 videos in PCA and MSA. A control group of 19 hearing students was tested with the same task. Sentences in each language variety were coded for grammatical versus ungrammatical productions and for type of morphosyntactic errors for the latter. In addition, code-switched words were counted.

RESULTS

The hearing group showed no morphosyntactic errors, whereas the DHH students showed morphosyntactic errors in both PCA and MSA. In addition, both groups code-switched in both PCA and MSA, with more code-switching in the MSA task than in the PCA task. Furthermore, an interaction with age revealed that young students code-switched more in MSA and older students code-switched more in PCA.

CONCLUSIONS

It is suggested that the morphosyntactic abilities of DHH students are incomplete in both language varieties. Lack of spoken language input may negatively influence the acquisition of spoken language, which impacts further the acquisition of the standard language in diglossic contexts. Code-switching is explained as both due to lexical gaps, when occurring in MSA, and an effort to raise the register in PCA.

Syntax intervention in American Sign Language: an exploratory case study

This case study describes the use of a syntax intervention with two deaf children who did not acquire a complete first language (L1) from birth. It looks specifically at their ability to produce subject-verb-object (SVO) sentence structure in American Sign Language (ASL) after receiving intervention. This was an exploratory case study in which investigators utilized an intervention that contained visuals to help teach SVO word order to young deaf children. Baseline data were collected over three sessions before implementation of a targeted syntax intervention and two follow-up sessions over 3-4 weeks. Both participants demonstrated improvements in their ability to produce SVO structure in ASL in 6-10 sessions. Visual analysis revealed a positive therapeutic trend that was maintained in follow-up sessions. These data provide preliminary evidence that a targeted intervention may help young deaf children with an incomplete L1 learn to produce basic word order in ASL. Results from this case study can help inform the practice of professionals working with signing deaf children who did not acquire a complete L1 from birth (e.g., speech-language pathologists, deaf mentors/coaches, ASL specialists, etc.). Future research should investigate the use of this intervention with a larger sample of deaf children.

Impoverished language in early childhood affects the development of complex sentence structure

The hypothesis that impoverished language experience affects complex sentence structure development around the end of early childhood was tested using a fully randomized, sentence-to-picture matching study in American Sign Language (ASL). The participants were ASL signers who had impoverished or typical access to language in early childhood. Deaf signers whose access to language was highly impoverished in early childhood (N = 11) primarily comprehended structures consisting of a single verb and argument (Subject or Object), agreeing verbs, and the spatial relation or path of semantic classifiers. They showed difficulty comprehending more complex sentence structures involving dual lexical arguments or multiple verbs. As predicted, participants with typical language access in early childhood, deaf native signers (N = 17) or hearing second-language learners (N = 10), comprehended the range of 12 ASL sentence structures, independent of the subjective iconicity or frequency of the stimulus lexical items, or length of ASL experience and performance on non-verbal cognitive tasks. The results show that language experience in early childhood is necessary for the development of complex syntax. RESEARCH HIGHLIGHTS: Previous research with deaf signers suggests an inflection point around the end of early childhood for sentence structure development. Deaf signers who experienced impoverished language until the age of 9 or older comprehend several basic sentence structures but few complex structures. Language experience in early childhood is necessary for the development of complex sentence structure.

Did the three little pigs frighten the wolf? How deaf readers use lexical and syntactic cues to comprehend sentences

BACKGROUND

The ways in which students with deafness process syntactic and semantic cues while reading sentences are unclear. While some studies have supported the preference for semantic cues, others have not.

AIM

To examine differences in the processing of syntactic versus semantic cues during sentence reading among students who are deaf or hard of hearing (DHH).

METHOD

Twenty DHH students (mean age = 12.48 years) and 20 chronologically age-matched students with typical hearing (TH) were asked to read sentences written in Spanish with different grammatical structures and to choose the picture that best matched the sentences' meaning while their eye movements were being registered. The picture options were manipulated so that, in addition to the correct ones, there were lexical distractors and syntactic distractors.

RESULTS

The TH participants outperformed the DHH participants in reading complex sentences but not simple sentences in the active voice. In the correctly answered trials, both groups fixated longer and made more fixations on the target than on the syntactic distractor than on the lexical distractor. DHH participants made significantly longer fixations on the lexical distractions.

CONCLUSIONS

Our results did not support a strict preference for either lexical or semantic cues in the DHH participants.

The Effect of Syntactic Impairment on Errors in Reading Aloud: Text Reading and Comprehension of Deaf and Hard of Hearing Children

Deaf and Hard of Hearing (DHH) children show difficulties in reading aloud and comprehension of texts. Here, we examined the hypothesis that these reading difficulties are tightly related to the syntactic deficit displayed by DHH children. We first assessed the syntactic abilities of 32 DHH children communicating in spoken language (Hebrew) aged 9;1-12;2. We classified them into two groups of DHH children-with and without a syntactic deficit according to their performance in six syntactic tests assessing their comprehension and production of sentences with syntactic movement. We also assessed their reading at the single word level using a reading aloud test of words, nonwords, and word pairs, designed to detect the various types of dyslexia, and established, for each participant, whether they had dyslexia and of what type. Following this procedure, 14 of the children were identified with a syntactic deficit, and 15 with typical syntax (3 marginally impaired); 22 of the children had typical reading at the word level, and 4 had dyslexia (3 demonstrated sublexical reading). The main experiment examined reading aloud and comprehension of 6 texts with syntactic movement (which contained, e.g., relative clauses and topicalized sentences), in comparison to 6 parallel texts without movement. The results indicated a close connection between syntactic difficulties and errors in reading aloud and in comprehension of texts. The DHH children with syntactic deficit made significantly more errors in reading aloud and more comprehension errors than the DHH children with intact syntax (and than the hearing controls), even though most of them did not have dyslexia at the word level. The DHH children with syntactic deficit made significantly more reading errors when they read texts with syntactic movement than on matched texts without movement. These results indicate that difficulties in text reading, manifesting both in errors in reading aloud and in impaired comprehension, may stem from a syntactic deficit and may occur even when reading at the word level is completely intact.

Psychometric properties of the mandarin clinical evaluation of language for preschooler's core scale

PURPOSE

To test the psychometric properties of a newly developed Mandarin Clinical Evaluation of Language for Preschooler's Core Scale (MCELP-CS).

METHODS

Data were collected from 379 preschool-aged participants, including 81 children with language disorders associated with clinical conditions. The 155-item MCELP-CS consists of five subscales: vocabulary comprehension (VC), sentence comprehension (SC), vocabulary naming (VN), sentence structure imitation (SSI), and story narration (SN). The scale was used to measure the receptive and expressive language abilities of children aged 3-5 years and 11 months. The Peabody Picture Vocabulary Test-revised (PPVT-R) was used to measure the receptive vocabulary abilities among the children (n = 338). The internal consistency, test-retest reliability, structural validity, convergent validity, and diagnostic accuracy were used to evaluate the scale. Differences between age groups were also examined using analysis of variance.

RESULTS

The MCELP-CS had high internal consistency and good test-retest reliability. Fitting indices of the two-factor model from confirmatory factor analysis (CFA), including χ², CFI, TLI, RSEAM, and SRMR, suggested that the model is consistent with the theoretical structure. Significant correlations between the MCELP-CS and PPVT-R showed a high convergent validity. In addition, the scale indicated good diagnostic accuracy in differentiating the language disorders of children with autism, cerebral palsy (CP), and hearing impairment (HI).

CONCLUSIONS

The MCELP-CS is a reliable and valid diagnostic tool for language disorders of Mandarin-speaking preschool children with autism, CP, and HI. It is appropriate to collect normative data for the MCELP-CS with a large sample population of preschool children.

The relationship between comprehension of syntax and reading comprehension in cochlear implanted and hearing children

OBJECTIVES

There is a large variation in the function of cochlear implanted children in language assessments. However, they usually have poorer performance in language abilities compared with their normal hearing peers. The purpose of the present study was to determine the relationship between syntax comprehension and reading comprehension in cochlear implanted and hearing children in the third to fifth grades of the elementary school and to identify the relationship between their reading comprehension and the age of receiving a cochlear implant as well as the duration of receiving speech therapy in cochlear implanted children.

METHODS

A total of 15 cochlear implanted children and 15 hearing children studying in the third to fifth grades of the elementary school participated in the present descriptive-analytic and cross-sectional study. Two skills of reading comprehension and syntax comprehension were evaluated in these two groups of children.

RESULTS

The results showed that there was a significant relationship between reading comprehension and comprehension of syntax in cochlear implanted children (P < 0.001). According to the linear regression, the score of reading comprehension increases with the increase in the score of syntax comprehension. No significant relationship was observed between reading comprehension and the age of receiving a cochlear implant (p = 0.337) and the duration of receiving speech therapy (p = 0.227).

CONCLUSION

Based on the findings of the present study, it can be concluded that focusing on comprehension of syntax for intervention can improve reading comprehension. Particularly, it seems that working on structures which are complicated for the children helps to improve their reading comprehension.

ASD Is Not DLI: Individuals With Autism and Individuals With Syntactic DLI Show Similar Performance Level in Syntactic Tasks, but Different Error Patterns

Do individuals with autism have a developmental syntactic impairment, DLI (formerly known as SLI)? In this study we directly compared the performance of 18 individuals with Autism Spectrum Disorder (ASD) aged 9;0–18;0 years with that of 93 individuals with Syntactic-Developmental Language Impairment (SyDLI) aged 8;8–14;6 (and with 166 typically-developing children aged 5;2–18;1). We tested them using three syntactic tests assessing the comprehension and production of syntactic structures that are known to be sensitive to syntactic impairment: elicitation of subject and object relative clauses, reading and paraphrasing of object relatives, and repetition of complex syntactic structures including Wh questions, relative clauses, topicalized sentences, sentences with verb movement, sentences with A-movement, and embedded sentences. The results were consistent across the three tasks: the overall rate of correct performance on the syntactic tasks is similar for the children with ASD and those with SyDLI. However, once we look closer, they are very different. The types of errors of the ASD group differ from those of the SyDLI group—the children with ASD provide various types of pragmatically infelicitous responses that are not evinced in the SyDLI or in the age equivalent typically-developing groups. The two groups (ASD and SyDLI) also differ in the pattern of performance—the children with SyDLI show a syntactically-principled pattern of impairment, with selective difficulty in specific sentence types (such as sentences derived by movement of the object across the subject), and normal performance on other structures (such as simple sentences). In contrast, the ASD participants showed generalized low performance on the various sentence structures. Syntactic performance was far from consistent within the ASD group. Whereas all ASD participants had errors that can originate in pragmatic/discourse difficulties, seven of them had completely normal syntax in the structures we tested, and were able to produce, understand, and repeat relative clauses, Wh questions, and topicalized sentences. Only one ASD participant showed a syntactically-principled deficit similar to that of individuals with SyDLI. We conclude that not all individuals with ASD have syntactic difficulties, and that even when they fail in a syntactic task, this does not necessarily originate in a syntactic impairment. This shows that looking only at the total score in a syntactic test may be insufficient, and a fuller picture emerges once the performance on different structures and the types of erroneous responses are analyzed.

A Deficit in Movement-Derived Sentences in German-Speaking Hearing-Impaired Children

Children with hearing impairment (HI) show disorders in syntax and morphology. The question is whether and how these disorders are connected to problems in the auditory domain. The aim of this paper is to examine whether moderate to severe hearing loss at a young age affects the ability of German-speaking orally trained children to understand and produce sentences. We focused on sentence structures that are derived by syntactic movement, which have been identified as a sensitive marker for syntactic impairment in other languages and in other populations with syntactic impairment. Therefore, our study tested subject and object relatives, subject and object Wh-questions, passive sentences, and topicalized sentences, as well as sentences with verb movement to second sentential position. We tested 19 HI children aged 9;5-13;6 and compared their performance with hearing children using comprehension tasks of sentence-picture matching and sentence repetition tasks. For the comprehension tasks, we included HI children who passed an auditory discrimination task; for the sentence repetition tasks, we selected children who passed a screening task of simple sentence repetition without lip-reading; this made sure that they could perceive the words in the tests, so that we could test their grammatical abilities. The results clearly showed that most of the participants with HI had considerable difficulties in the comprehension and repetition of sentences with syntactic movement: they had significant difficulties understanding object relatives, Wh-questions, and topicalized sentences, and in the repetition of object who and which questions and subject relatives, as well as in sentences with verb movement to second sentential position. Repetition of passives was only problematic for some children. Object relatives were still difficult at this age for both HI and hearing children. An additional important outcome of the study is that not all sentence structures are impaired-passive structures were not problematic for most of the HI children.

New language outcome measures for Mandarin speaking children with hearing loss

Objective

The paper discusses recent evidence on the assessment of language outcomes in children with hearing loss acquiring oral language.

Methods

Research emphasizes that language tests must be specific enough to capture subtle deficits in vocabulary and grammar learning at different developmental ages. The Diagnostic Receptive and Expressive Assessment of Mandarin (DREAM) was carefully designed to be a comprehensive standardized Mandarin assessment normed in Mainland China.

Results

This paper summarizes the evidence-based item design process and validity and reliability results of DREAM. A pilot study reported here shows that DREAM provided detailed information about hearing impaired children's language abilities and can be used to aid intervention planning to maximize progress.

Conclusion

DREAM represents an example of translational science, transferring methods from empirical studies of language acquisition in research environments into applied domains such as assessment and intervention. Research on outcomes in China will advance significantly with the availability of evidence-based comprehensive language tests that measure a sufficient age range of skills, are normed on Mandarin speaking children in mainland China, and are designed to capture features central to Mandarin language acquisition.
