Abstract
BACKGROUND It is unclear whether phonological awareness and vocabulary knowledge are independent predictors of reading fluency for deaf children in different grades. AIMS This study examined the relative contributions of phonological awareness and vocabulary knowledge to Chinese deaf children's reading fluency in grades 3-4 (lower grades; mean age 14.08 years) and 5-6 (higher grades; mean age 15.05 years). METHODS AND PROCEDURES One hundred and forty-one deaf children and 163 hearing children were enrolled. All children completed assessments of general cognitive ability, onset and tone awareness, vocabulary knowledge and reading fluency. OUTCOMES AND RESULTS The results showed that for lower-grade deaf children, the unique effect of onset awareness on reading fluency was not statistically significant, but it was an independent predictor in higher grades; for lower-grade hearing children, onset awareness accounted for variance in reading fluency, but its effect was not significant in higher grades. No significant effect of tone awareness was found in deaf or hearing children. However, vocabulary knowledge significantly explained the variance in reading fluency for all subgroups. CONCLUSIONS AND IMPLICATIONS The predictive patterns of phonological awareness on reading fluency are complex and depend on many factors, while vocabulary knowledge is an important and consistent predictor for both deaf and hearing children.

Abstract
Background: Phonological awareness (PA) is a fundamental predictor of reading disability. However, researches on reading have indicated that PA assessment alone is not sufficient to prevent reading problems. Rapid automatized naming (RAN) has been suggested as another influential factor in reading deficits independent of PA. This study investigated the impact of phonological awareness on rapid automatized naming.
Methods: This was a randomized clinical trial study in which 62 Persian monolingual first graders were recruited from 3 schools using convenience sampling. Inclusion criteria were lack of deficits with sensory-motor skills and knowledge of the Persian alphabets. Measures of PA and RAN were utilized. The participants were randomly assigned into either the intervention or the control group. The intervention group was divided into small groups of 4-6 children who received thirty 40-minute training sessions in PA. T test, Mann-Whitney, and Wilcoxon tests were used for data analysis.
Results: The results revealed that the RAN time was significantly reduced (p≤0.001), with a significant increase in PA scores (p≤0.001). In addition, there was a significant inverse relationship between some of the measures of the phonological awareness subtests and rapid automatized naming (eg, phonemic blending & RAN (numbers): ρ=-0.52 with p≤0.001).
Conclusion: The findings showed that in the initial assessment, PA and RAN had a significant relationship, but RAN could be significantly improved by PA training.

Abstract
Reading acquisition is strongly intertwined with phoneme awareness that relies on implicit phoneme representations. We asked whether phoneme representations emerge before literacy. We recruited two groups of children, 4 to 5-year-old preschoolers (N = 29) and 7 to 8-year-old schoolchildren (N = 24), whose phonological awareness was evaluated, and one adult control group (N = 17). We altered speakers' auditory feedback in real time to elicit persisting pronunciation changes, referred to as auditory-motor adaptation or learning. Assessing the transfer of learning at phoneme level enabled us to investigate the developmental time-course of phoneme representations. Significant transfer at phoneme level occurred in preschoolers, as well as schoolchildren and adults. In addition, we found a relationship between auditory-motor adaptation and phonological awareness in both groups of children. Overall, these results suggest that phoneme representations emerge before literacy acquisition, and that these sensorimotor representations may set the ground for phonological awareness.

Abstract
BACKGROUND Children born preterm are at risk for developing reading difficulties and for decrements in other cognitive skills compared to children born at term. AIMS To assess how domains of function, often negatively impacted by preterm birth, predict reading development in children born preterm and at term. STUDY DESIGN Longitudinal descriptive cohort study. SUBJECTS Preterm (n = 48; gestational age 22-32 weeks, 30 males) and term (n = 41, 18 males) participants were assessed at age 6 years on a battery of verbal and non-verbal cognitive skills and reassessed at age 8 using the Gray Oral Reading Tests-5. Linear regressions assessed the contributions of phonological awareness, language, executive function, and non-verbal IQ at age 6 to reading outcome at age 8. RESULTS Children born preterm had lower scores than children born at term on all measures (Cohen's d from 0.46 to 1.08, all p < .05). Phonological awareness and language abilities predicted reading in both groups (accounting for 19.9% and 25.0% of variance, respectively, p < .001). Birth group did not moderate the association. By contrast, the association between executive function and non-verbal intelligence and reading outcome was moderated by birth group (interaction accounted for 3.9-6.7% of variance, respectively, p < .05). Positive predictions to reading from executive function and non-verbal IQ were found only in children born preterm. CONCLUSIONS Non-verbal cognitive skills improved the prediction of reading outcome only in the preterm group, suggesting that reading decrements represent a component of global deficits. These findings have implications for evaluation of children born preterm at school entry and treatment of reading difficulties.

Abstract
BACKGROUND There are few studies on hiragana reading skill and phonological awareness in Japanese schoolchildren with periventricular leukomalacia (PVL). METHODS Three seven-year-old children with PVL who had no intellectual disabilities or dysarthria were recruited. Their perinatal information, brain magnetic resonance image (MRI) at term equivalent age, accompanying neurodevelopmental disorders, ophthalmologic features, Kaufman Assessment Battery for Children (K-ABC), a hiragana reading test (four tasks), and a phonological awareness task (mora reversal tasks) were analyzed. RESULTS Patient (Pt) 1 and pt2 were male. Pt2 and pt3 were siblings of triplets. Their gestational age was 28 or 32 weeks, and their birth weights were 1196, 1554, and 1848 g, respectively. Their brain MRI revealed cystic or non-cystic periventricular white matter injury involving the deep white matter at the trigone of both lateral ventricles. Pt1 had attention-deficit/hyperactivity disorder and pt3 had pervasive developmental disorder not otherwise specified. All patients had strabismus with spared best-corrected visual acuity. Scores of Reading/Decoding in K-ABC ranged from 89 to 99. As for the single mora reading task or the non-word reading task in the kana reading test, Z scores of their reading time ranged from 2.3 to 5.9 compared to control children. Pt1 and pt3 made significant errors in the mora reversal task of three-mora words, whereas all patients could answer all words correctly in the mora reversal task of two-mora words. CONCLUSION All children showed significantly prolonged reading time despite their adequate letter recognition. Two patients showed delayed phonological awareness. It was suggested that hiragana decoding impairment due to subcortical and/or cortical injury related to PVL affected their reading ability.

Abstract
Auditory temporal processing (ATP) has been related in the literature to both speech perception as well as reading and phonological awareness. In aging adults, it is known to be related to difficulties in speech perception. In the present study, we aimed to test whether an age-related deficit in ATP would also be accompanied by poor reading and phonological awareness. Thirty-eight aging adults were compared to 55 readers with dyslexia and 42 young normal readers on temporal order judgment (TOJ), speech perception, reading, and phonological awareness tests. Aging adults had longer TOJ thresholds than young normal readers, but shorter than readers with dyslexia; however, they had lower speech perception accuracy than both groups. Phonological awareness of the aging adults was better than readers with dyslexia, but poorer than young normal readers, although their reading accuracy was similar to that of the young controls. This is the first report on poor phonological awareness among aging adults. Suprisingly, it was not accompanied by difficulties in reading ability, and might instead be related to aging adults' difficulties in speech perception. This newly discovered relationship between ATP and phonological awareness among aging adults appears to extend the existing understanding of this relationship, and suggests it should be explored in other groups with ATP deficits.

Abstract
This study examined pinyin (the official phonetic system that transcribes the lexical tones and pronunciation of Chinese characters) invented spelling and English invented spelling in 72 Mandarin-speaking 6th graders who learned English as their second language. The pinyin invented spelling task measured segmental-level awareness including syllable and phoneme awareness, and suprasegmental-level awareness including lexical tones and tone sandhi in Chinese Mandarin. The English invented spelling task manipulated segmental-level awareness including syllable awareness and phoneme awareness, and suprasegmental-level awareness including word stress. This pinyin task outperformed a traditional phonological awareness task that only measured segmental-level awareness and may have optimal utility to measure unique phonological and linguistic features in Chinese reading. The pinyin invented spelling uniquely explained variance in Chinese conventional spelling and word reading in both languages. The English invented spelling uniquely explained variance in conventional spelling and word reading in both languages. Our findings appear to support the role of phonological activation in Chinese reading. Our experimental linguistic manipulations altered the phonological awareness item difficulties.

Abstract
Letter knowledge is considered an important cognitive foundation for learning to read. The underlying mechanisms of the association between letter knowledge and reading skills are, however, not fully understood. Acquiring letter knowledge depends on the ability to learn and retrieve sound-symbol pairings. In the current study, this process was explored by setting preschool children's (N = 242, mean age = 5.57 years) performance in the acquisition and retrieval of a paired associate learning (PAL) task in relation to their letter knowledge as well as to their performance in tasks assessing precursors of reading skills (i.e., phonological awareness, rapid automatized naming, phonological short-term memory, backward recall, and response inhibition). Multiple regression analyses revealed that performance in the acquisition of the PAL task was significantly associated with phonological awareness and backward recall, whereas performance in the retrieval of the PAL task was significantly associated with rapid automatized naming, phonological awareness, and backward recall. Moreover, PAL proved to be mediating the relation between reading precursors and letter knowledge. Together, these findings indicate that the acquisition of letter knowledge may depend on a visual-verbal associative learning mechanism and that different factors contribute to the acquisition and retrieval of such visual-verbal associations.

Abstract
PURPOSE Developmental dyslexia is commonly viewed as a phonological deficit that makes it difficult to decode written language. But children with dyslexia typically exhibit other problems, as well, including poor speech recognition in noise. The purpose of this study was to examine whether the speech-in-noise problems of children with dyslexia are related to their reading problems, and if so, if a common underlying factor might explain both. The specific hypothesis examined was that a spectral processing disorder results in these children receiving smeared signals, which could explain both the diminished sensitivity to phonological structure - leading to reading problems - and the speech recognition in noise difficulties. The alternative hypothesis tested in this study was that children with dyslexia simply have broadly based language deficits. PARTICIPANTS Ninety-seven children between the ages of 7 years; 10 months and 12 years; 9 months participated: 46 with dyslexia and 51 without dyslexia. METHODS Children were tested on two dependent measures: word reading and recognition in noise with two types of sentence materials: as unprocessed (UP) signals, and as spectrally smeared (SM) signals. Data were collected for four predictor variables: phonological awareness, vocabulary, grammatical knowledge, and digit span. RESULTS Children with dyslexia showed deficits on both dependent and all predictor variables. Their scores for speech recognition in noise were poorer than those of children without dyslexia for both the UP and SM signals, but by equivalent amounts across signal conditions indicating that they were not disproportionately hindered by spectral distortion. Correlation analyses on scores from children with dyslexia showed that reading ability and speech-in-noise recognition were only mildly correlated, and each skill was related to different underlying abilities. CONCLUSIONS No substantial evidence was found to support the suggestion that the reading and speech recognition in noise problems of children with dyslexia arise from a single factor that could be defined as a spectral processing disorder. The reading and speech recognition in noise deficits of these children appeared to be largely independent.

Abstract
Background The DSM-5 separates the diagnostic criteria for mood and behavioral disorders. Both types of disorders share neurocognitive deficits of executive function and reading difficulties in childhood. Children with dyslexia also have executive function deficits, revealing a role of executive function circuitry in reading. The aim of the current study is to determine whether there is a significant relationship of functional connectivity within the fronto-parietal and cingulo-opercular cognitive control networks to reading measures for children with mood disorders, behavioral disorders, dyslexia, and healthy controls (HC). Method Behavioral reading measures of phonological awareness, decoding, and orthography were collected. Resting state fMRI data were collected, preprocessed, and then analyzed for functional connectivity. Differences in the reading measures were tested for significance among the groups. Global efficiency (GE) measures were also tested for correlation with reading measures in 40 children with various disorders and 17 HCs. Results Significant differences were found between the four groups on all reading measures. Relative to HCs and children with mood disorders or behavior disorders, children with dyslexia as a primary diagnosis scored significantly lower on all three reading measures. Children with mood disorders scored significantly lower than controls on a test of phonological awareness. Phonological awareness deficits correlated with reduced resting state functional connectivity MRI (rsfcMRI) in the cingulo-opercular network for children with dyslexia. A significant difference was also found in fronto-parietal global efficiency in children with mood disorders relative to the other three groups. We also found a significant difference in cingulo-opercular global efficiency in children with mood disorders relative to the Dyslexia and Control groups. However, none of these differences correlate significantly with reading measures. Conclusions/significance Reading difficulties involve abnormalities in different cognitive control networks in children with dyslexia compared to children with mood disorders. Findings of the current study suggest increased functional connectivity of one cognitive control network may compensate for reduced functional connectivity in the other network in children with mood disorders. These findings provide guidance to clinical professionals for design of interventions tailored for children suffering from reading difficulties originating from different pathologies.

Abstract
The left ventral occipitotemporal cortex (vOT) is important in visual word recognition. Studies have shown that the left vOT is generally observed to be involved in spoken language processing in skilled readers, suggesting automatic access to corresponding orthographic information. However, little is known about where and how the left vOT is involved in the spoken language processing of young children with emerging reading ability. In order to answer this question, we examined the relation of reading ability in 5-6-year-old kindergarteners to the activation of vOT during an auditory phonological awareness task. Two experimental conditions: onset word pairs that shared the first phoneme and rhyme word pairs that shared the final biphone/triphone, were compared to allow a measurement of vOT's activation to small (i.e., onsets) and large grain sizes (i.e., rhymes). We found that higher reading ability was associated with better accuracy of the onset, but not the rhyme, condition. In addition, higher reading ability was only associated with greater sensitivity in the posterior left vOT for the contrast of the onset versus rhyme condition. These results suggest that acquisition of reading results in greater specialization of the posterior vOT to smaller rather than larger grain sizes in young children.

Abstract
During early literacy skills development, rhyming is an important indicator of the phonological precursors required for reading. To determine if neural signatures of rhyming are apparent in early childhood, we recorded event-related potentials (ERPs) from 3- to 5-year-old, preliterate children (N = 62) in an auditory prime-target nonword rhyming paradigm (e.g., bly-gry, blane-vox). Overall, nonrhyming targets elicited a larger negativity (N450) than rhyming targets over posterior regions. In contrast, rhyming targets elicited a larger negativity than nonrhyming targets over fronto-lateral sites. The amplitude of the two rhyming effects was correlated, such that a larger posterior effect occurred with a smaller anterior effect. To determine whether these neural signatures of rhyming related to phonological awareness, we divided the children into two groups based on phonological awareness scores while controlling for age and socioeconomic status. The posterior rhyming effect was stronger and more widely distributed in the group with better phonological awareness, whereas differences between groups for the anterior effect were small and not significant. This pattern of results suggests that the rhyme processes indexed by the anterior effect are developmental precursors to those indexed by the posterior effect. Overall, these findings demonstrate early establishment of distributed neurocognitive networks for rhyme processing.

Abstract
UNLABELLED In the present study, we investigated (i) to what extent the early literacy skills (phonological awareness, letter knowledge, and word decoding) along with cognitive (nonverbal reasoning, attention, phonological short-term memory, sequential memory, executive functioning) and linguistic (auditory discrimination, rapid naming, articulation, vocabulary) precursor measures of 53 six-year old children with intellectual disabilities (ID) differ from a group of 74 peers with normal language acquisition (NLA) and (ii) whether the individual variation of early literacy skills in the two groups to the same extent can be explained from the precursor measures. Results showed that children with ID scored below the NLA group on all literacy and precursor measures. Structural equation modeling evidenced that in the children with NLA early literacy was directly predicted by phonological awareness, PSTM and vocabulary, with nonverbal reasoning and auditory discrimination also predicting phonological awareness. In children with ID however, the variation in word decoding was predicted by letter knowledge and nonverbal reasoning, whereas letter knowledge was predicted by rapid naming, which on its turn was predicted by attentional skills. It can be concluded phonological awareness plays a differential role in the early literacy skills of children with and without ID. As a consequence, the arrears in phonological awareness in children with ID might put them on hold in gaining proper access to literacy acquisition. WHAT THIS PAPER ADDS This paper adds to the theoretical knowledge base on literacy acquisition in a special population, namely children with intellectual disabilities (ID). It addresses factors that influence early literacy learning, which have not been investigated thoroughly in this special and specific group. Furthermore, the children are not tested solely on literacy, but also on cognitive measures that may influence literacy acquisition. Whereas most research in ID focuses on groups with specific syndromes/etiologies, this paper takes a varied group of children with ID into account. The paper also adds to educational insights, since the findings imply that children with ID are able to use phonological pathways in learning to read. Educators could teach these children phonics-based literacy skills tailored to their individual learning needs.

Abstract
The temporo-occipitally distributed N170 ERP component is hypothesized to reflect print-tuning in skilled readers. This study investigated whether skilled deaf and hearing readers (matched on reading ability, but not phonological awareness) exhibit similar N170 patterns, given their distinct experiences learning to read. Thirty-two deaf and 32 hearing adults viewed words and symbol strings in a familiarity judgment task. In the N170 epoch (120-240ms) hearing readers produced greater negativity for words than symbols at left hemisphere (LH) temporo-parietal and occipital sites, while deaf readers only showed this asymmetry at occipital sites. Linear mixed effects regression was used to examine the influence of continuous measures of reading, spelling, and phonological skills on the N170 (120-240ms). For deaf readers, better reading ability was associated with a larger N170 over the right hemisphere (RH), but for hearing readers better reading ability was associated with a smaller RH N170. Better spelling ability was related to larger occipital N170s in deaf readers, but this relationship was weak in hearing readers. Better phonological awareness was associated with smaller N170s in the LH for hearing readers, but this association was weaker and in the RH for deaf readers. The results support the phonological mapping hypothesis for a left-lateralized temporo-parietal N170 in hearing readers and indicate that skilled reading is characterized by distinct patterns of neural tuning to print in deaf and hearing adults.

Abstract
PURPOSE There is strong empirical evidence that English-speaking children with spoken language difficulties (SLD) often have phonological awareness (PA) deficits. The aim of this study was to explore longitudinally if this is also true of pre-school children speaking German, a language that makes extensive use of derivational morphemes which may impact on the acquisition of different PA levels. METHOD Thirty 4-year-old children with SLD were assessed on 11 PA subtests at three points over a 12-month period and compared with 97 four-year-old typically developing (TD) children. RESULT The TD-group had a mean percentage correct of over 50% for the majority of tasks (including phoneme tasks) and their PA skills developed significantly over time. In contrast, the SLD-group improved their PA performance over time on syllable and rhyme, but not on phoneme level tasks. Group comparisons revealed that children with SLD had weaker PA skills, particularly on phoneme level tasks. CONCLUSION The study contributes a longitudinal perspective on PA development before school entry. In line with their English-speaking peers, German-speaking children with SLD showed poorer PA skills than TD peers, indicating that the relationship between SLD and PA is similar across these two related but different languages.

Abstract
OBJECTIVE The aim was to explore PA skills German-speaking preschool children with cochlea implants (CIs) and how these skills may be related to their speech and language skills. METHODS Three monolingual German-speaking pre-school children aged 5;04-6;01 with bilateral CIs were tested. Their cognitive, speech and language skills were assessed. Six subtests of a standardized PA test battery were administered (i.e. rhyme identification, rhyme production; phoneme identification- input and -output; phoneme blending-input and -output). RESULTS All three children showed distinctive PA profiles. One boy, who had no spoken language deficits, struggled to complete the rhyme tasks but performed well on three phoneme tasks. However, he showed a discrepancy between expressive and receptive phoneme blending skills, scoring poorly on the expressive subtest. The second boy, who displayed grammar comprehension and expressive vocabulary difficulties, showed a mixed profile, with a below average performance on rhyme production. The girl who had significant speech and language deficits scored below average on all six PA subtests. CONCLUSIONS PA profiles in children with CI vary considerably and PA testing should include a range of different PA tasks. The assumed link between spoken language deficits and PA difficulties shown in children with normal hearing could be confirmed.

Abstract
The goal of the current study was to examine the feasibility of a telepractice intervention to improve phonological awareness skills in children with hearing loss as compared to a conventional in-person intervention. Twenty children with hearing loss participated in this study. Two groups of ten children each received a supplemental phonological awareness intervention either via telepractice or an in-person service delivery model. Within each of the two groups, five children were enrolled in preschool or kindergarten and five children were enrolled in first or second grade. The two groups of children demonstrated similar phonological awareness, non-verbal IQ, and vocabulary skills during pre-tests. After a 12-week intervention children with hearing loss showed improved phonological awareness skills as measured by a standardized post-test. No significant differences were found between the performance of the telepractice group and in-person group. Nor was a significant interaction found between the two age groups (PreK/K vs. 1st /2nd grade) and the two types of service delivery models (in-person vs. telepractice). The results suggest that a telepractice service delivery model is feasible for young children with hearing loss, and that telepractice may be as effective as in-person intervention in improving phonological awareness skills.

Abstract
Associative learning, traditionally measured with paired associate learning (PAL) tasks, has been found to predict reading ability in several languages. However, it remains unclear whether it also predicts word reading in Chinese, which is known for its ambiguous print-sound correspondences, and whether its effects are direct or indirect through the effects of other reading-related skills such as phonological awareness and rapid naming. Thus, the purpose of this study was to examine the direct and indirect effects of visual-verbal PAL on word reading in an unselected sample of Chinese children followed from the second to the third kindergarten year. A sample of 141 second-year kindergarten children (71 girls and 70 boys; mean age=58.99months, SD=3.17) were followed for a year and were assessed at both times on measures of visual-verbal PAL, rapid naming, and phonological awareness. In the third kindergarten year, they were also assessed on word reading. The results of path analysis showed that visual-verbal PAL exerted a significant direct effect on word reading that was independent of the effects of phonological awareness and rapid naming. However, it also exerted significant indirect effects through phonological awareness. Taken together, these findings suggest that variations in cross-modal associative learning (as measured by visual-verbal PAL) place constraints on the development of word recognition skills irrespective of the characteristics of the orthography children are learning to read.

Abstract
In the current research we investigate the role of early phonological awareness skills on reading development in diglossic Arabic. Two-hundred and six Arabic speaking first graders, composed of 25 at-linguistic risk pupils (LR group) and 181 normally developing readers, representing the found heterogeneity in the classroom participated in this study. For this purpose, phonological training program was developed where we followed the pupils' development in both phonological awareness skills and reading development in second grade. As indicated by the study results, higher achievements in phonological awareness measures was noted among HG group in first grade. After Training, significant improvement in phonological awareness was noted among both groups, where LR group was able to close the gaps in phonological awareness skills with HG group. When examining the relationship between phonological awareness and reading performance, moderate positive correlation was found within HG group whereas strong positive relationship was encountered with the LR group. Despite the progress in phonological awareness skills and its strong relationship with reading, LR group showed lower reading performance when compared to HG group. The study results are discussed in relation to its scientific and didactic implications on Arabic reading acquisition.

Abstract
The present longitudinal study aimed to investigate the development of word decoding skills during incremental phonics instruction in Dutch as a transparent orthography. A representative sample of 973 Dutch children in the first grade (Mage = 6;1, SD = 0;5) was exposed to incremental subsets of Dutch grapheme-phoneme correspondences during 6 consecutive blocks of 3 weeks of phonics instruction. Children's accuracy and efficiency of curriculum embedded word decoding were assessed after each incremental block, followed by a standardized word decoding measurement. Precursor measures of rapid naming, short-term memory, vocabulary, phonological awareness, and letter knowledge were assessed by the end of kindergarten and subsequently related to the word decoding efficiency in the first grade. The results showed that from the very beginning, children attained ceiling levels of decoding accuracy, whereas their efficiency scores increased despite the incremental character of the consecutive decoding assessments embedded in the curriculum. Structural equation modelling demonstrated high stability of the individual differences assessed by word decoding efficiency during phonics instruction during the first 5 months of the first grade. Curriculum embedded word decoding was highly related to standardized word decoding after phonics instruction was completed. Finally, early literacy and lexical retrieval, and to a lesser extent verbal and visual short term memory, predicted the first fundamental processes of mastering word decoding skills.

Abstract
OBJECTIVE To clarify cognitive processes underlining the development of reading in children speaking Japanese as their first language, we examined relationships between performances of cognitive tasks in the preschool period and later reading abilities. METHODS Ninety-one normally developing preschoolers (41 girls and 50 boys; 5years 4months to 6years 4months, mean 5years 10months) participated as subjects. We conducted seven cognitive tasks including phonological awareness tasks, naming tasks, and working memory tasks in the preschool period. In terms of reading tasks, the hiragana naming task was administered in the preschool period; the reading times, which is a composite score of the monomoraic syllable reading task, the word and the non-word reading tasks, and the single sentence reading task, was evaluated in first and second grade; and the kanji reading task (naming task) was tested in second grade. Raven's colored progressive matrices and picture vocabulary test revised were also conducted in first grade. Correlation analyses between task scores and stepwise multiple regression analyses were implemented. RESULTS Tasks tapping phonological awareness, lexical access, and verbal working memory showed significant correlations with reading tasks. In the multiple regression analyses the performances in the verbal working memory task played a key role in predicting character naming task scores (the hiragana naming task and the kanji reading task) while the digit naming task was an important predictor of reading times. Unexpectedly, the role of phonological (mora) awareness was modest among children speaking Japanese. CONCLUSION Cognitive functions including phonological awareness, digit naming, and verbal working memory (especially the latter two) were involved in the development of reading skills of children speaking Japanese.

Abstract
OBJECTIVE Precise temporal coding of speech plays a pivotal role in sound processing throughout the central auditory system, which, in turn, influences literacy acquisition. The current study tests whether an electrophysiological measure of this precision predicts literacy skills. METHODS Complex auditory brainstem responses were analysed from 62 native German-speaking children aged 11-13years. We employed the cross-phaseogram approach to compute the quality of the electrophysiological stimulus contrast [da] and [ba]. Phase shifts were expected to vary with literacy. RESULTS Receiver operating curves demonstrated a feasible sensitivity and specificity of the electrophysiological measure. A multiple regression analysis resulted in a significant prediction of literacy by delta cross-phase as well as phonological awareness. A further commonality analysis separated a unique variance that was explained by the physiological measure, from a unique variance that was explained by the behavioral measure, and common effects of both. CONCLUSIONS Despite multicollinearities between literacy, phonological awareness, and subcortical differentiation of stop consonants, a combined assessment of behavior and physiology strongly increases the ability to predict literacy skills. SIGNIFICANCE The strong link between the neurophysiological signature of sound encoding and literacy outcome suggests that the delta cross-phase could indicate the risk of dyslexia and thereby complement subjective psychometric measures for early diagnoses.

Abstract
As reading development progresses, the visual processing of word forms becomes increasingly left-lateralized. This is visible, among other ways, as increased left-lateralization of the N170 ERP component. A primary explanation of this effect, the phonological mapping hypothesis, proposes that the left-lateralization of visual word form processing that accompanies reading development is the result of calling upon left hemisphere auditory language regions to perform the linking of orthography with phonology (phonological mapping). A key, but untested, prediction of the phonological mapping hypothesis is thus that individuals with greater phonological awareness should exhibit more left lateralized visual processing of word forms than individuals with poorer phonological awareness. We set out to test this hypothesis here. We accomplished this by collecting ERPs while children grades 5-6 viewed words, objects, and word/object ambiguous items (e.g., "SMILE" shaped like a smile - hereafter referred to as wobjects). Results revealed that, consistent with the phonological mapping hypothesis, individual phonological awareness (but not other measures of reading development) predicted left-lateralization of the N170 component elicited in response to words (but not item types that were not word-like).

Abstract
PURPOSE Newborn hearing screening has made it possible to provide early treatment of hearing loss to more children than ever before, raising expectations these children will be able to attend regular schools. But continuing deficits in spoken language skills have led to challenges in meeting those expectations. This study was conducted to (1) examine two kinds of language skills (phonological and morphosyntactic) at school age (second grade) for children with cochlear implants (CIs); (2) see which measures from earlier in life best predicted performance at second grade; (3) explore how well these skills supported other cognitive and language functions; and (4) examine how treatment factors affected measured outcomes. METHODS Data were analyzed from 100 second-grade, monolingual English-speaking children: 51 with CIs and 49 with normal hearing (NH). Ten measures of spoken language and related functions were collected: three each of phonological and morphosyntactic skills; and four of other cognitive and language functions. Six measures from preschool and seven from kindergarten served as predictor variables. The effects of treatment variables were examined. RESULTS Children with CIs were more delayed acquiring phonological than morphosyntactic skills. Mean length of utterance at earlier ages was the most consistent predictor of both phonological and morphosyntactic skills at second grade. Early bimodal stimulation had a weak, but positive effect on phonological skills at second grade; sign language experience during preschool had a negative effect on morphosyntactic structures in spoken language. CONCLUSIONS Children with CIs are delayed in language acquisition, and especially so in phonological skills. Appropriate testing and treatments can help ameliorate these delays.

Abstract
Phonological processing is a fundamental ability which underlies language comprehension. Functional neuroanatomy of phonology constitutes a matter of ongoing debate. In the present study, subjects performed visual (rhyme detection) and auditory (identification of spoken words starting with a given consonant) tasks that were contrasted with matched nonverbal tasks. We identified regions critical for phonological processing which were either stimulus specific or supramodal. The results revealed a high degree of modality specificity in both visual and auditory networks. Moreover, we observed a modality independent region in the left middle temporal gyrus (MTG)/superior temporal sulcus (STS), between a more anterior temporal area with auditory specificity and a more posterior temporal area with visual specificity. This dissociation in functional neuroanatomy suggests that this area may be a core region for supramodal phonological processing, acting as a gateway between spatially separate, but stimulus specific, phonological processes and more general linguistic functions.

Abstract
OBJECTIVES Early auditory experience plays a major role in language acquisition. Linguistic and metalinguistic abilities of children aged 5-5.5 years with cochlear implants (CIs) were compared to age-matched children with normal hearing (NH) to investigate the effect of hearing on development of these two skills. METHODS Eighteen children with NH and 18 children with CIs took part in the study. The Test of Language Development-Primary, third edition, was used to assess language and metalinguistic skills by assessment of phonological awareness (PA). Language skills and PA were then compared between groups. Hierarchical linear regression was conducted to determine whether the language skills explained the unique variance in PA. RESULTS There were significant differences between children with NH and those with CIs for language skills and PA (p≤0.001). All language skills (semantics, syntax, listening, spoken language, organizing, and speaking) were uniquely predictive of PA outcome in the CI children. Linear combinations of listening and semantics and listening, semantics, and syntax correlated significantly with PA. CONCLUSION The results show that children with CIs may have trouble with language skills and PA. Listening, semantics, and syntax, among other skills, are significant indicators of the variance in PA for children with CIs.

Abstract
The goal of this longitudinal study was to examine how lexical quality predicts the emergence of literacy abilities in 169 Dutch kindergarten children before formal reading instruction has started. At the beginning of the school year, a battery of precursor measures associated with lexical quality was related to the emergence of letter knowledge and word decoding. Confirmatory factor analysis evidenced five domains related to lexical quality, i.e., vocabulary, phonological coding, phonological awareness, lexical retrieval and phonological working memory. Structural equation modeling showed that the development of letter knowledge during the year could be predicted from children's phonological awareness and lexical retrieval, and the emergence of word decoding from their phonological awareness and letter knowledge. It is concluded that it is primarily the accessibility of phonological representations in the mental lexicon that predicts the emergence of literacy in kindergarten.

Abstract
BACKGROUND AND AIMS Children with good phonological awareness (PA) are often good word readers. Here, we asked whether Swedish deaf and hard-of-hearing (DHH) children who are more aware of the phonology of Swedish Sign Language, a language with no orthography, are better at reading words in Swedish. METHODS AND PROCEDURES We developed the Cross-modal Phonological Awareness Test (C-PhAT) that can be used to assess PA in both Swedish Sign Language (C-PhAT-SSL) and Swedish (C-PhAT-Swed), and investigated how C-PhAT performance was related to word reading as well as linguistic and cognitive skills. We validated C-PhAT-Swed and administered C-PhAT-Swed and C-PhAT-SSL to DHH children who attended Swedish deaf schools with a bilingual curriculum and were at an early stage of reading. OUTCOMES AND RESULTS C-PhAT-SSL correlated significantly with word reading for DHH children. They performed poorly on C-PhAT-Swed and their scores did not correlate significantly either with C-PhAT-SSL or word reading, although they did correlate significantly with cognitive measures. CONCLUSIONS AND IMPLICATIONS These results provide preliminary evidence that DHH children with good sign language PA are better at reading words and show that measures of spoken language PA in DHH children may be confounded by individual differences in cognitive skills.

Abstract
Despite the importance of phonological awareness for the development of reading in alphabetic languages, little attention has been paid to its developmental origins. In this study, dual-process, latent growth models were used to examine patterns of bidirectional relations between letter knowledge and phonological awareness during preschool. The sample comprised 358 children (mean age=48.60 months, SD=7.26). Growth models were used to quantify the unique longitudinal relations between the initial level of each skill and growth in the other skill during the preschool year, after controlling for initial level of the same skill, vocabulary, age, and growth in the code-related skill being used as a predictor. Letter-name knowledge and phonological awareness were bidirectionally related; the initial level of each uniquely predicted growth in the other. Initial letter-sound knowledge and phonological awareness growth were not uniquely related, and vocabulary was not related to growth in phonological awareness. These findings extend the evidence of the relation between letter knowledge and phonological awareness to supra-phonemic tasks, indicating that this bidirectional relation begins at an earlier point in the development of phonological awareness than previously reported. In addition, these findings help to rule out general growth in letter knowledge and phonological awareness as an alternative explanation for the bidirectional relation between these two code-related skills.

Abstract
BACKGROUND Rhyming ability is among the earliest metaphonological skills to be acquired during the process of speech and language acquisition. Metalinguistic skills, particularly metaphonological skills, greatly influence language learning during early, school grades and reportedly children with learning disorders are poor at these skills. AIM AND OBJECTIVES To develop and validate a Bengali rhyming checklist and study the auditory perception of non-sense and familiar Bengali rhyming words in children with and without specific learning disability (SLD). METHOD 60 children, age range 8-11years, participated in two groups; group-A included children with SLD and group-B, typically developing children (TDC). All participants were native Bengali speakers, attending regular school, with hearing sensitivity less than 25dBHL, no history of ear discharge and middle socioeconomic background. A rhyming checklist was developed in Bengali, consisting of familiar (section-A) and non-sense (section-B) words. Test-retest reliability and validity measures were obtained. The items on the checklist were audio recorded and presented to the participants in a rhyming judgment task in one to one set up. Scores were obtained and statistically analyzed using SPSS software (version-11.0). RESULT Children with SLD scored significantly low on the rhyming judgment task as against TDC (p<.05) for both familiar and non-sense words. Children with SLD performed significantly better on familiar word rhyming judgment task against non-sense words (p<.05). TDC showed no significant difference on familiar and non-sense words rhyming judgment tasks (p>.05). CONCLUSION Semantic content influences rhyming perception in children with SLD but has no significant effect on TDC. The developed rhyming checklist may be used as a screening tool for children at risk of SLD at primary school grades. Rhyming activities may be utilized by teachers and parents, to promote language learning in young learners.

Abstract
The double-deficit hypothesis (DDH) of the developmental dyslexias (Wolf and Bowers, Journal of Educational Psychology, 91, 415-438, 1999) was investigated with 149 adolescents and young adults (age range = 16 to 24 years) with dyslexia. Confirmatory factor analysis indicated that a two-factor model with separate naming speed (NS) and phonological awareness (PA) constructs was superior to a one-factor model, supporting the assumption within the DDH that NS is a source of reading dysfunction separable from PA. Hierarchical multiple regression analyses resulted in findings that were only partially supportive of the DDH. NS was predictive of word reading, spelling, and reading fluency beyond PA and verbal intellectual ability, but not pseudoword reading and timed and untimed reading comprehension. Examination of DDH subtypes did not support the core assumption of the DDH that the double-deficit subtype would have more impaired reading skills than both of the single-deficit subtypes. The NS deficit subtype was found to be more prevalent than the double-deficit and PA deficit subtypes within the subgroup of dyslexics with impairment in reading fluency. Overall results provided mixed support for the DDH and pointed to the need for the inclusion of additional abilities within theories of the underlying mechanisms disrupted in dyslexia.

Abstract
Two studies aimed to investigate the reading comprehension abilities of 14 readers with Down syndrome aged 6 years 8 months to 13 years relative to those of typically developing children matched on word reading ability, and to investigate how these abilities were associated with reading accuracy, listening comprehension, phonological awareness and vocabulary knowledge. Study 1 confirmed significantly poorer passage-reading comprehension than the typically developing group. In an experimental task, readers with Down syndrome understood fewer written sentences than the typical group and, contrary to prediction, received no advantage from printed sentences compared to spoken sentences, despite the lower memory load. Reading comprehension was associated with listening comprehension, word reading and phonological awareness in DS. Vocabulary knowledge was also associated with reading comprehension, mediated by word reading and nonverbal cognitive abilities. Study 2 investigated the longitudinal relationships between reading and language measures in the readers with DS over around 22 months. Time 1 listening comprehension and phonological awareness predicted Time 2 reading comprehension but there was no evidence that reading or reading comprehension predicted Time 2 language scores or phonological awareness, and no evidence that readers had acquired greater depth of vocabulary.

Abstract
Two important foundations for learning are language and executive skills. Data from a longitudinal study tracking the development of 93 children at family-risk of dyslexia and 76 controls was used to investigate the influence of these skills on the development of arithmetic. A two-group longitudinal path model assessed the relationships between language and executive skills at 3-4 years, verbal number skills (counting and number knowledge) and phonological processing skills at 4-5 years, and written arithmetic in primary school. The same cognitive processes accounted for variability in arithmetic skills in both groups. Early language and executive skills predicted variations in preschool verbal number skills, which in turn, predicted arithmetic skills in school. In contrast, phonological awareness was not a predictor of later arithmetic skills. These results suggest that verbal and executive processes provide the foundation for verbal number skills, which in turn influence the development of formal arithmetic skills. Problems in early language development may explain the comorbidity between reading and mathematics disorder.

Abstract
This study examined how well nonverbal IQ (or fluid intelligence), vocabulary, phonological awareness (PA), rapid autonomized naming (RAN), and phonological short-term memory (STM) predicted mathematics outcomes. The 208 participating kindergartners were administered tests of fluid intelligence, vocabulary, PA, RAN, STM, and numeracy in the fall of kindergarten, whereas tests of numeracy and applied problems were administered in the spring of kindergarten. Fall numeracy scores accounted for substantial variation in spring outcomes (R(2) values = .49 and .32 for numeracy and applied problems, respectively), which underscores the importance of preschool math instruction and screening for mathematics learning difficulties on entry into kindergarten. Fluid intelligence and PA significantly predicted unique variation in spring numeracy scores (ΔR(2) = .05) after controlling for autoregressive effects and classroom nesting. Fluid intelligence, PA, and STM significantly predicted unique variation in spring applied problems scores (ΔR(2) = .14) after controlling for autoregressive effects and classroom nesting. Although the contributions of fluid intelligence, PA, and STM toward math outcomes were reliable and arguably important, they were small.

Abstract
The extent to which phonological, visual-spatial short-term memory (STM), and nonsymbolic quantitative skills support the development of counting and calculation skills was examined in this 14-month longitudinal study of 125 children. Initial assessments were made when the children were 4 years 8 months old. Phonological awareness, visual-spatial STM, and nonsymbolic approximate discrimination predicted growth in early calculation skills.These results suggest that both the approximate number system and domain-general phonological and visual-spatial skills support early calculation. In contrast, only performance on a small nonsymbolic quantity discrimination task (where the presented quantities were always within the subitizing range) predicted growth in cardinal counting skills. These results suggest that the development of counting and the development of calculation are supported by different cognitive abilities.

Deconstructing phonological tasks: The contribution of stimulus and response type to the prediction of early decoding skills. Cognition 2015; 143:178-86.

Abstract
Phonological tasks are highly predictive of reading development but their complexity obscures the underlying mechanisms driving this association. There are three key components hypothesised to drive the relationship between phonological tasks and reading; (a) the linguistic nature of the stimuli, (b) the phonological complexity of the stimuli, and (c) the production of a verbal response. We isolated the contribution of the stimulus and response components separately through the creation of latent variables to represent specially designed tasks that were matched for procedure. These tasks were administered to 570 6 to 7-year-old children along with standardised tests of regular word and non-word reading. A structural equation model, where tasks were grouped according to stimulus, revealed that the linguistic nature and the phonological complexity of the stimulus predicted unique variance in decoding, over and above matched comparison tasks without these components. An alternative model, grouped according to response mode, showed that the production of a verbal response was a unique predictor of decoding beyond matched tasks without a verbal response. In summary, we found that multiple factors contributed to reading development, supporting multivariate models over those that prioritize single factors. More broadly, we demonstrate the value of combining matched task designs with latent variable modelling to deconstruct the components of complex tasks.

Abstract
This study's research question was whether selective visual attention, and specifically the attentional blink (AB) as operationalized by a dual target rapid serial visual presentation (RSVP) task, can explain individual differences in word reading (WR) and reading-related phonological performances in typically developing children and reading-disabled subgroups. A total of 407 Dutch school children (Grades 3-6) were classified either as typically developing (n = 302) or as belonging to one of three reading-disabled subgroups: reading disabilities only (RD-only, n = 69), both RD and attention problems (RD+ADHD, n = 16), or both RD and a specific language impairment (RD+SLI, n = 20). The RSVP task employed alphanumeric stimuli that were presented in two blocks. Standardized Dutch tests were used to measure WR, phonemic awareness (PA), and alphanumeric rapid naming (RAN). Results indicate that, controlling for PA and RAN performance, general RSVP task performance contributes significant unique variance to the prediction of WR. Specifically, consistent group main effects for the parameter of AB(minimum) were found, whereas there were no AB-specific effects (i.e., AB(width) and AB(amplitude)) except for the RD+SLI group. Finally, there was a group by measurement interaction, indicating that the RD-only and comorbid groups are differentially sensitive for prolonged testing sessions. These results suggest that more general factors involved in RSVP processing may explain the group differences found.

Abstract
Our study investigated if phonological awareness and letter-sound knowledge were predictors of reading progress in children with intellectual disabilities (ID) with unspecified etiology. An academic achievement test was administered to 129 children with mild or moderate ID when they were 6-8 years old, as well as one and two school years later. Findings indicated that phonological awareness and letter-sound knowledge at 6-8 years of age predicted progress in word and non-word reading after one school year and two school years after controlling for IQ, age, expressive vocabulary, spoken language, and type of placement. Phonological awareness and letter-sound knowledge at 6-8 years of age also predicted progress in reading comprehension after one school year and two school years. These findings suggest that training phonological awareness skills combined with explicit phonics instruction is important to foster reading progress in children with mild and moderate ID with unspecified etiology.

Abstract
PURPOSE This study investigated the content validity of a computer-based phonological awareness (PA) screening and monitoring assessment (Com-PASMA) designed to evaluate school-entry PA abilities. Establishing content validity by confirming that test items suitably 'fit' and sample a spectrum of difficulty levels is critical for ensuring educators can deduce accurate information to comprehensively differentiate curricular reading instruction. METHOD Ninety-five children, inclusive of 21 children with spoken language impairment, participated in a 1-year longitudinal study whereby the Com-PASMA was administered at the start, middle and end of the school year. RESULT Estimates of content validity using Rasch Model analysis demonstrated that: (1) rhyme oddity and initial phoneme identity tasks were most appropriate at school-entry and sampled a spectrum of difficulty levels, (2) more challenging phoneme level tasks (e.g. final phoneme identity, phoneme blending, phoneme deletion and phoneme segmentation) became increasingly appropriate and differentiated between high- and low-ability students by the middle and end of the first year of school and (3) letter-knowledge tasks were appropriate but declined in their ability to differentiate student ability as the year progressed. CONCLUSION Findings demonstrate that the Com-PASMA has sufficient content validity to measure and differentiate between the PA abilities of 5-year-old children on entry to school.

Abstract
Natural sound environments are dynamic, with overlapping acoustic input originating from simultaneously active sources. A key function of the auditory system is to integrate sensory inputs that belong together and segregate those that come from different sources. We hypothesized that this skill is impaired in individuals with phonological processing difficulties. There is considerable disagreement about whether phonological impairments observed in children with developmental language disorders can be attributed to specific linguistic deficits or to more general acoustic processing deficits. However, most tests of general auditory abilities have been conducted with a single set of sounds. We assessed the ability of school-aged children (7-15 years) to parse complex auditory non-speech input, and determined whether the presence of phonological processing impairments was associated with stream perception performance. A key finding was that children with language impairments did not show the same developmental trajectory for stream perception as typically developing children. In addition, children with language impairments required larger frequency separations between sounds to hear distinct streams compared to age-matched peers. Furthermore, phonological processing ability was a significant predictor of stream perception measures, but only in the older age groups. No such association was found in the youngest children. These results indicate that children with language impairments have difficulty parsing speech streams, or identifying individual sound events when there are competing sound sources. We conclude that language group differences may in part reflect fundamental maturational disparities in the analysis of complex auditory scenes.

Abstract
The screening and monitoring of phonological awareness (PA) in the classroom is of great importance to the early identification and prevention of reading disorder. This study investigated whether a time-efficient computer-based PA screening and monitoring assessment (Com-PASMA) could accurately predict end-of-year reading outcomes for 5-year-old children in the first year of schooling. A longitudinal design was employed where the Com-PASMA was used to measure the PA ability of 95 5-year-old children at the start, middle, and end of the first year of school. Of this group, 21 children presented with spoken language impairment. Reading outcomes were formally measured after 1 year of schooling. School-entry measures of PA using the Com-PASMA (p < .001), in conjunction with language ability (p = .004), accounted for 68.9% of the variance in end-of-year word decoding ability. Sensitivity and specificity calculations demonstrated that the Com-PASMA was 92% accurate at school-entry, and 94% accurate by the middle of the school year in predicting reading outcomes at 6-years of age. Results suggest that a time-efficient computer-based method of screening and monitoring PA can support the early identification of reading difficulties in the first year of schooling.

Abstract
We examined in a series of studies the mechanism that may underlie the relationship between Rapid Automatized Naming (RAN) and reading (accuracy and fluency) in Mandarin Chinese. Study 1 examined the "arbitrary" connections hypothesis in a sample of Grade 2 children (N=182). Study 2 contrasted the phonological processing, orthographic processing, and speed of processing hypotheses in a sample of Grade 2 children followed until Grade 5 (N=72). Finally, Study 3 contrasted the same hypotheses in a sample of Grade 4 children with dyslexia (n=30) and chronological-age controls (n=30). The results indicated that (a) RAN is unrelated to Paired Associate Learning (PAL) tasks that tap the ability to form arbitrary connections between characters and their pronunciation, (b) controlling for nonverbal IQ and orthographic processing was sufficient to explain the RAN-reading accuracy relationship but not the RAN-reading fluency relationship, and (c) the observed differences between dyslexics and controls in RAN diminished after controlling for orthographic processing. Taken together, these findings suggest that RAN is related to reading accuracy (and partly to reading fluency) because children must access orthographic representations from long-term memory. Although accessing these representations is sufficient for accurate word recognition, it is not sufficient for fluent reading, which also requires efficient parafoveal processing.

Abstract
OBJECTIVES Phonological and working memory skills have been shown to be important for the development of spoken language. Children who use a cochlear implant (CI) show performance deficits relative to normal hearing (NH) children on all constructs: phonological skills, working memory, and spoken language. Given that phonological skills and working memory have been shown to be important for spoken language development in NH children, we hypothesized that training these foundational skills would result in improved spoken language performance in CI-using children. DESIGN Nineteen prelingually deafened CI-using children aged 4- to 7-years-old participated. All children had been using their implants for at least one year and were matched on pre-implant hearing thresholds, hearing thresholds at study enrollment, and non-verbal IQ. Children were assessed on expressive vocabulary, listening language, spoken language, and composite language. Ten children received four weeks of training on phonological skills including rhyme, sound blending, and sound discrimination and auditory working memory. The remaining nine children continued with their normal classroom activities for four weeks. Language assessments were repeated following the training/control period. RESULTS Children who received combined phonological-working memory training showed significant gains on expressive and composite language scores. Children who did not receive training showed no significant improvements at post-test. On average, trained children had gain scores of 6.35 points on expressive language and gain scores of 6.15 points whereas the untrained children had test-retest gain scores of 2.89 points for expressive language and 2.56 for composite language. CONCLUSION Our results suggest that training to improve the phonological and working memory skills in CI-using children may lead to improved language performance.

Abstract
Background and Objectives The primary purpose of this study was to assess whether very early access to speech sounds provided by the cochlear implant enables children to develop age-appropriate phonological awareness abilities in their preschool and school years. A secondary purpose of this study was to examine whether children who had cochlear implantation before 18 months of age will develop better skills in phonological awareness than children who had cochlear implants in 18-36 months of age. A third purpose of this study was to examine whether some factors like the child's age or sex would have any effects on developing of age-appropriate phonological awareness abilities. Subjects and Methods 48 children with 70 to 95 months of age who had been utilizing their cochlear implant(s) before 36 months of age (CI group) and 30 normal hearing peers (NH group) were enrolled in this study. Results Child's age had a significant effect on phonological awareness, but sex had absolutely no effect in each group. Children in the cochlear implanted group were outperformed by their normal hearing peers in the area of phonological awareness, especially in phonemic awareness. The age of implantation was another significant variable. Conclusions Although children with a younger age at implantation got better scores in phonological awareness test, they were outperformed by their normal hearing peers in this area.

Abstract
Many studies have examined reading and reading development. The majority of these studies, however, focused on oral reading rather than on the more dominant silent reading mode. Similarly, it is common practice to assess oral reading abilities rather than silent reading abilities in schools and in diagnosis of reading impairments. More important, insights gained through examinations of oral reading tend to be generalized to silent reading. In the current study, we examined whether such generalizations are justified. We directly compared oral and silent reading fluency by examining whether these reading modes relate to the same underlying skills. In total, 132 fourth graders read words, sentences, and text orally, and 123 classmates read the same material silently. As underlying skills, we considered phonological awareness, rapid naming, and visual attention span. All skills correlated significantly with both reading modes. Phonological awareness contributed equally to oral and silent reading. Rapid naming, however, correlated more strongly with oral reading than with silent reading. Visual attention span correlated equally strongly with both reading modes but showed a significant unique contribution only to silent reading. In short, we showed that oral and silent reading indeed are fairly similar reading modes, based on the relations with reading-related cognitive skills. However, we also found differences that warrant caution in generalizing findings across reading modes.

Abstract
UNLABELLED Children with Specific Language Impairment (SLI) have severe language difficulties without showing hearing impairments, cognitive deficits, neurological damage or socio-emotional deprivation. However, previous studies have shown that children with SLI show some cognitive and literacy problems. Our study analyses the relationship between preschool cognitive and linguistic abilities and the later development of reading abilities in Spanish-Catalan bilingual children with SLI. The sample consisted of 17 bilingual Spanish-Catalan children with SLI and 17 age-matched controls. We tested eight distinct processes related to phonological, attention, and language processing at the age of 6 years and reading at 8 years of age. Results show that bilingual Spanish-Catalan children with SLI show significantly lower scores, as compared to typically developing peers, in phonological awareness, phonological memory, and rapid automatized naming (RAN), together with a lower outcome in tasks measuring sentence repetition and verbal fluency. Regarding attentional processes, bilingual Spanish-Catalan children with SLI obtained lower scores in auditory attention, but not in visual attention. At the age of 8 years Spanish-Catalan children with SLI had lower scores than their age-matched controls in total reading score, letter identification (decoding), and in semantic task (comprehension). Regression analyses identified both phonological awareness and verbal fluency at the age of 6 years to be the best predictors of subsequent reading performance at the age of 8 years. Our data suggest that language acquisition problems and difficulties in reading acquisition in bilingual children with SLI might be related to the close interdependence between a limitation in cognitive processing and a deficit at the linguistic level. LEARNING OUTCOMES After reading this article, readers will be able to: identify their understanding of the relation between language difficulties and reading outcomes; explain how processing abilities influence reading performance in bilingual Spanish-Catalan children with SLI; and recognize the relation between language and reading via a developmental model in which the phonological system is considered central for the development of decoding abilities and comprehension.

Abstract
The present study investigated the linguistic and cognitive predictors of early literacy in 17 children with intellectual disabilities (ID) (mean age: 7; 6 years) compared to 24 children with normal language acquisition (NLA) (mean age: 6; 0 years), who were all in the so-called partial alphabetic phase of reading (Ehri, 2005). In each group, children's performances in early literacy skills (phonological awareness, letter knowledge, and word decoding) were assessed, as well as their achievement in linguistic and cognitive measures associated to these skills. The results showed that, notwithstanding the fact that there were no differences in word decoding, children with ID lagged behind on all predictor measures relevant to early literacy skills compared to children with NLA. Moreover, whereas children with NLA showed a regular predictive pathway of early literacy skills, children with ID showed a deviant pattern, in which nonverbal intelligence and rhythmic skills proved to be of major importance. Also letter knowledge appeared to be involved in their early literacy processing. It can be tentatively concluded that in the ID group, children's level of nonverbal intellectual abilities in combination with rhythmic ability proves pivotal in the development of their early literacy skills.

Pelczarski KM, Yaruss JS. Phonological encoding of young children who stutter. JOURNAL OF FLUENCY DISORDERS 2014; 39:12-24. [PMID: 24759190 DOI: 10.1016/j.jfludis.2013.10.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2012] [Revised: 09/25/2013] [Accepted: 10/25/2013] [Indexed: 06/03/2023]
Abstract
PURPOSE Several empirical studies suggest that children who stutter, when compared to typically fluent peers, demonstrate relatively subtle, yet robust differences in phonological encoding. Phonological encoding can be measured through the use of tasks that reflect the underlying mechanisms of phonological processing, such as phonological awareness. This study investigated the phonological encoding abilities of five- and six-year old children who stutter. METHODS Young children who stutter were paired according to language ability, maternal education, and sex to their typically fluent peers. Participants completed multiple measures of phonological awareness abilities (i.e., sound matching, phoneme blending, elision), as well as measures of expressive and receptive vocabulary and articulation. RESULTS Young children who stutter performed significantly less well than nonstuttering peers on tasks of elision and sound blending. No between-group differences were found in sound matching abilities or in any of the background language measures. CONCLUSIONS Results suggest that young children who stutter have subtle, yet robust, linguistic differences in certain aspects of phonological encoding that may contribute to an unstable language planning system in young children who stutter. EDUCATIONAL OBJECTIVES The reader will be able to: (a) describe how phonological awareness can inform our understanding of phonological encoding; (b) summarize the findings of previously published studies that examined some aspects of phonological awareness in children who do and do not stutter; and (c) compare the results of the current study with other investigations of phonological awareness skills in children who stutter and their typically fluent peers.

J Exp Child Psychol 2014; 122:75-91.

Abstract
This 2-year longitudinal study sought to identify a developmental pattern of Chinese and English reading skills in children with and without dyslexia from 6 to 8years of age. Three groups of 15 children each-those with dyslexia, age-matched (AM) controls, and reading-matched (RM) controls-participated. Dyslexia was diagnosed at 8years of age. All children were tested on phonological awareness, rapid automatized naming (RAN), morphological awareness, word reading, and vocabulary knowledge in both Chinese and English and also speed of processing skill. AM controls outperformed the group with dyslexia on all measures except for phonological awareness, English word reading, and vocabulary. However, those with dyslexia and AM controls developed at a similar rate across all reading-related skills from 6 to 8years of age. Compared with the RM controls, the group with dyslexia scored higher in phonological awareness, morphological awareness, and vocabulary knowledge in both Chinese and English and also in English word reading but scored similarly in RAN. Children with dyslexia, thus, manifested clear difficulties in Chinese vocabulary knowledge, morphological awareness, and RAN as well as general speed of processing, representing a developmental lag in cognitive skills. Among these, RAN deficits are likely to be the most severe deficits in Chinese children with dyslexia.

Abstract
Learning outcomes are associated with a variety of environmental and cognitive factors, and the aim of the current study was to compare the predictive power of these factors in longitudinal outcomes. We recruited children in kindergarten and tested their learning outcomes 2 years later. In kindergarten, children completed tests of IQ, phonological awareness, and memory (sentence memory, short-term memory, and working memory). After 2 years, they took national assessments in reading, writing, and math. Working memory performance was not affected by socioeconomic status (SES), whereas IQ, phonological awareness, and sentence memory scores differed as a function of SES. A series of hierarchical regression analyses indicated that working memory and phonological awareness were better predictors of learning than any other factors tested, including SES. Educational implications include providing intervention during the early years to boost working memory and phonological awareness so as to prevent subsequent learning difficulties.
