Reading component skills in dyslexia: word recognition, comprehension and processing speed.

The cognitive model of reading comprehension (RC) posits that RC is a result of the interaction between decoding and linguistic comprehension. Recently, the notion of decoding skill was expanded to include word recognition. In addition, some studies suggest that other skills could be integrated into this model, like processing speed, and have consistently indicated that this skill influences and is an important predictor of the main components of the model, such as vocabulary for comprehension and phonological awareness of word recognition. The following study evaluated the components of the RC model and predictive skills in children and adolescents with dyslexia. 40 children and adolescents (8–13 years) were divided in a Dyslexic Group (DG; 18 children, MA = 10.78, SD = 1.66) and control group (CG 22 children, MA = 10.59, SD = 1.86). All were students from the 2nd to 8th grade of elementary school and groups were equivalent in school grade, age, gender, and IQ. Oral and RC, word recognition, processing speed, picture naming, receptive vocabulary, and phonological awareness were assessed. There were no group differences regarding the accuracy in oral and RC, phonological awareness, naming, and vocabulary scores. DG performed worse than the CG in word recognition (general score and orthographic confusion items) and were slower in naming. Results corroborated the literature regarding word recognition and processing speed deficits in dyslexia. However, dyslexics can achieve normal scores on RC test. Data supports the importance of delimitation of different reading strategies embedded in the word recognition component. The role of processing speed in reading problems remain unclear.

Musical rhythm discrimination explains individual differences in grammar skills in children.

This study considered a relation between rhythm perception skills and individual differences in phonological awareness and grammar abilities, which are two language skills crucial for academic achievement. Twenty-five typically developing 6-year-old children were given standardized assessments of rhythm perception, phonological awareness, morpho-syntactic competence, and non-verbal cognitive ability. Rhythm perception accounted for 48% of the variance in morpho-syntactic competence after controlling for non-verbal IQ, socioeconomic status, and prior musical activities. Children with higher phonological awareness scores were better able to discriminate complex rhythms than children with lower scores, but not after controlling for IQ. This study is the first to show a relation between rhythm perception skills and morpho-syntactic production in children with typical language development. These findings extend the literature showing substantial overlap of neurocognitive resources for processing music and language.

The relation between morphological awareness and reading and spelling in Greek: a longitudinal study

The aim of this longitudinal study is to examine the contribution of morphological awareness to the prediction of reading and spelling in Greek. The target group (N = 404) consisted of children, aged 6–9 years at the start of the project, who learn literacy in Cyprus. Because there are no standardized measures of morphological awareness for Greek Cypriot children, morphological awareness measures were developed and validated. A concurrent analysis of the first wave of data collection showed that morphological awareness made a unique contribution to the prediction of reading and spelling in Greek. The longitudinal analyses showed that morphological awareness predicted performance in reading eight months later, even after partialling out grade level, verbal intelligence, phonological awareness and initial scores in reading and spelling. This study makes theoretical, empirical and practical educational contributions. It shows the long term and specific relation of morphological awareness with reading in Greek and establishes the plausibility of a causal link between morphological awareness and reading, which must be tested in further research using intervention methods. In practice, this study contributes valid measures for assessing morphological awareness in Greek as well as a new measure of spelling skill.

Home sweet home: Does where you live matter to working memory and other cognitive skills?

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 2years later. In kindergarten, children completed tests of IQ, phonological awareness, and memory (sentence memory, short-term memory, and working memory). After 2years, 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.

Identifying phonological awareness difficulties in preschool children with speech sound disorders

Phonological awareness is one type of phonological processing ability and is considered to be particularly important for early literacy development. Specific phonological awareness skills include syllable-level awareness, onset-rime awareness, and phonemic awareness. Children with speech sound disorders are at a high risk of difficulties with phonological awareness and literacy. There is a body of literature reporting both composite scores and task-specific phonological awareness scores from the assessment of children with typically developing speech and school-age children with speech sound disorders. In this study, we completed a systematic overview of the available literature regarding the assessment of phonological awareness in preschool-age children with speech sound disorders. A systematic search of literature databases yielded 777 articles which were screened. The full text of 30 articles was read and 12 articles met all specified criteria. Ten of the 12 articles reported composite scores for the phonological awareness of participants. The studies rarely reported the profile of specific phonological awareness skills. Of the final 12 articles, eight were case–control studies (Level III) and four were case-series or cross-sectional studies without a control reference (Level IV). There is a need for more research reporting task-specific phonological awareness abilities in preschool-age children with speech sound disorders in order to understand the relationship between specific skills and literacy development in this population.

Levels of Phonological Awareness, Working Memory, and Lexical Knowledge in Elementary School Children

Relationships between oral language, phonological awareness, and working memory have been empirically demonstrated, however, phonological awareness encompasses different abilities, assessed at different levels. The present study investigated the possible associations between specific phonological awareness abilities and phonological working memory in first-grade students. In the initial phase ( n = 254), the study evaluated the abilities of phonological awareness and phonological working memory and found a high positive correlation between these abilities, thus confirming the findings of previous studies. The second phase ( n = 12) evaluated the vocabulary of individuals who, in the initial phase, showed low or high working memory and phonological awareness scores. Students with low working memory and low phonological awareness capacities had low scores in expressive language abilities, suggesting that phonological working memory may have direct effects on lexical knowledge. These results contribute to the understanding of the relationships investigated in this study and have important implications for planning teaching strategies.

Tracking the Roots of Reading Ability: White Matter Volume and Integrity Correlate with Phonological Awareness in Prereading and Early-Reading Kindergarten Children

Developmental dyslexia, an unexplained difficulty in learning to read, has been associated with alterations in white matter organization as measured by diffusion-weighted imaging. It is unknown, however, whether these differences in structural connectivity are related to the cause of dyslexia or if they are consequences of reading difficulty (e.g., less reading experience or compensatory brain organization). Here, in 40 kindergartners who had received little or no reading instruction, we examined the relation between behavioral predictors of dyslexia and white matter organization in left arcuate fasciculus, inferior longitudinal fasciculus, and the parietal portion of the superior longitudinal fasciculus using probabilistic tractography. Higher composite phonological awareness scores were significantly and positively correlated with the volume of the arcuate fasciculus, but not with other tracts. Two other behavioral predictors of dyslexia, rapid naming and letter knowledge, did not correlate with volumes or diffusion values in these tracts. The volume and fractional anisotropy of the left arcuate showed a particularly strong positive correlation with a phoneme blending test. Whole-brain regressions of behavioral scores with diffusion measures confirmed the unique relation between phonological awareness and the left arcuate. These findings indicate that the left arcuate fasciculus, which connects anterior and posterior language regions of the human brain and which has been previously associated with reading ability in older individuals, is already smaller and has less integrity in kindergartners who are at risk for dyslexia because of poor phonological awareness. These findings suggest a structural basis of behavioral risk for dyslexia that predates reading instruction.

Preschool Speech Error Patterns Predict Articulation and Phonological Awareness Outcomes in Children With Histories of Speech Sound Disorders

To determine if speech error patterns in preschoolers with speech sound disorders (SSDs) predict articulation and phonological awareness (PA) outcomes almost 4 years later. Twenty-five children with histories of preschool SSDs (and normal receptive language) were tested at an average age of 4;6 (years;months) and were followed up at age 8;3. The frequency of occurrence of preschool distortion errors, typical substitution and syllable structure errors, and atypical substitution and syllable structure errors was used to predict later speech sound production, PA, and literacy outcomes. Group averages revealed below-average school-age articulation scores and low-average PA but age-appropriate reading and spelling. Preschool speech error patterns were related to school-age outcomes. Children for whom >10% of their speech sound errors were atypical had lower PA and literacy scores at school age than children who produced <10% atypical errors. Preschoolers who produced more distortion errors were likely to have lower school-age articulation scores than preschoolers who produced fewer distortion errors. Different preschool speech error patterns predict different school-age clinical outcomes. Many atypical speech sound errors in preschoolers may be indicative of weak phonological representations, leading to long-term PA weaknesses. Preschoolers' distortions may be resistant to change over time, leading to persisting speech sound production problems.

Improving neural response to sound improves reading.

Despite intense focus on improving reading scores, the most recently released National Assessment of Educational Progress reported that only one in three fourth grade students in the United States read at or above a proficient level, a change of only 5% since 1992 (1). In PNAS, Hornickel et al. (2) review the growing body of evidence that links reading failure to auditory processing disorders. They report that a group of dyslexic children who used an assistive listening FM system for one school year during classroom instruction significantly increased their phonological awareness (P < 0.001) and basic reading scores (P = 0.006). These data support an increasing number of studies that demonstrate that rapid and significant improvement in reading can result from auditory interventions. Their study also provides physiological data that supports the hypothesis that children with language learning impairments, including dyslexia, respond inconsistently to the rapidly changing spectrotemporal acoustic cues in speech and that this response becomes more consistent after auditory intervention.

Effect of phonological training in French children with SLI: Perspectives on voicing identification, discrimination and categorical perception

The aim of the present study was to investigate the effect of auditory training on voicing perception in French children with specific language impairment (SLI). We used an adaptive discrimination training that was centred across the French phonological boundary (0 ms voice onset time--VOT). One group of nine children with SLI attended eighteen twenty-minute training sessions with feedback, and a control group of nine children with SLI did not receive any training. Identification, discrimination and categorical perception were evaluated before, during and after training as well as one month following the final session. Phonological awareness and vocabulary were also assessed for both groups. The results showed that children with SLI experienced strong difficulties in the identification, discrimination and categorical perception of the voicing continuum prior to training. However, as early as after the first nine training sessions, their performance in the identification and discrimination tasks increased significantly. Moreover, phonological awareness scores improved during training, whereas vocabulary scores remained stable across sessions.

Transfer effects in spelling from transparent Greek to opaque English in seven-to-ten-year-old children

The study investigated single-word spelling performance of 33 English- and 38 Greek-speaking monolingual children, and 46 English- and Greek-speaking bilingual children (age range from 6;7 to 10;1 years). The bilingual children were divided into two groups on the basis of their single-word reading and spelling performance in Greek. In line with predictions, we found that scores on an assessment of phonological awareness were a significant predictor of spelling in English for the bilingual children with stronger Greek literacy skill. Phonological awareness scores were also a strong predictor of spelling in Greek in the monolingual Greek-speaking children. For the bilingual children with weaker Greek literacy ability, spelling in English was predicted by performance in a test of visual memory. This was more in line with results for the monolingual English-speaking children, for whom spelling performance was predicted by visual memory and phonological awareness scores. Qualitative analysis of misspellings revealed that phonologically appropriate errors were significantly greater in the strong Greek literacy ability bilingual group than the weaker Greek literacy ability bilingual group. Stimulus analyses using regression techniques are also reported. The results are interpreted to suggest that in biliterates literacy processes are transferred from one language to the other (Mumtaz &amp; Humphreys, 2002).

A comparative study of rapid naming and working memory as predictors of word recognition and reading comprehension in relation to phonological awareness in Iranian dyslexic and normal children

The present study investigated additional deficits beyond the documented problems of phonological processing in developmental dyslexia, concerning possible perceptual–motor automaticity and working memory (WM) ability. The participants consisted of 30 normal and 30 dyslexic children. A battery of intelligence, psychopathology, RAN-digit, short term memory (STM) and WM were administered to both groups, in addition to phonological ability and reading comprehension tests. Dyslexic children obtained significantly lower phonological awareness, RAN-digit speed, STM and WM scores. Working memory but not RANdigit predicted reading ability beyond phonological awareness. The findings are discussed based on the existing heterogeneity within dyslexia.

Enhancing vocabulary, print awareness and phonological awareness through shared storybook reading with low-income preschoolers

The current study compares the effects of two shared storybook reading (SSR) interventions on language and emergent literacy skills of low-income preschoolers. The control intervention targeted language and print awareness, skills for which there is strong evidence of the effect of SSR. The experimental intervention added a focus on phonological awareness, a skill for which there is less evidence of the effect of SSR. Following the interventions, results indicated that the experimental group ( n = 10) outperformed the control group ( n = 13) on phonological awareness scores, but not on vocabulary and print awareness scores. The study also compared the outcomes of the experimental intervention for the low-income participants with the skills of higher-income preschoolers who did not receive intervention. The low-income children in the experimental condition outperformed their higher-income peers ( n = 12) on all three measures. The experimental intervention offers promising techniques for SSR activities in childcare centres.

Using computer-based instruction to improve Indigenous early literacy in Northern Australia: A quasi-experimental study

&lt;span&gt;The effectiveness of a web-based reading support tool, ABRACADABRA, to improve the literacy outcomes of Indigenous and non-Indigenous students was evaluated over one semester in several Northern Territory primary schools in 2009. ABRACADABRA is intended as a support for teachers in the early years of schooling, giving them a friendly, game and evidence-based tool to reinforce their literacy instruction. The classroom implementation of ABRACADABRA by briefly trained and intensively supported teachers was evaluated using a quasi-experimental pretest, post-test control group design with 118 children in the intervention and 48 in the control. Children received either a minimum of 20 hours of technology-based intervention or regular classroom teaching. Results revealed both Indigenous and non-Indigenous students who received ABRACADABRA instruction had significantly higher phonological awareness scores than their control group peers. The effect size for this difference was large (eta squared=.14). This finding remained when controlling for student attendance and the quality of general non-technology-based literacy instruction. Limitations of the study and implications for effective practice in remote and regional contexts are discussed.&lt;/span&gt;

Effects of Bottom-Up and Top-Down Intervention Principles in Emergent Literacy in Children at Risk of Developmental Dyslexia: A Longitudinal Study

This longitudinal study focused on the effects of two different principles of intervention in children at risk of developing dyslexia from 5 to 8 years old. The children were selected on the basis of a background questionnaire given to parents and preschool teachers, with cognitive and functional magnetic resonance imaging results substantiating group differences in neuropsychological processes associated with phonology, orthography, and phoneme—grapheme correspondence (i.e., alphabetic principle). The two principles of intervention were bottom-up (BU), “from sound to meaning”, and top-down (TD), “from meaning to sound.” Thus, four subgroups were established: risk/BU, risk/TD, control/BU, and control/TD. Computer-based training took place for 2 months every spring, and cognitive assessments were performed each fall of the project period. Measures of preliteracy skills for reading and spelling were phonological awareness, working memory, verbal learning, and letter knowledge. Literacy skills were assessed by word reading and spelling. At project end the control group scored significantly above age norm, whereas the risk group scored within the norm. In the at-risk group, training based on the BU principle had the strongest effects on phonological awareness and working memory scores, whereas training based on the TD principle had the strongest effects on verbal learning, letter knowledge, and literacy scores. It was concluded that appropriate, specific, data-based intervention starting in preschool can mitigate literacy impairment and that interventions should contain BU training for preliteracy skills and TD training for literacy training.

Morphological Knowledge and Decoding Skills of Deaf Readers

Many studies have reported the necessity of phonological awareness to become a skilled reader, citing barriers to phonological information as the cause for reading difficulties experienced by deaf individuals. In contrast, other research suggests that phonological awareness is not necessary for reading acquisition, citing the importance of higher levels of syntactic and semantic knowledge. To determine if deaf students with higher language skills have better word decoding strategies, students responded to a morphological test, where monomorphemic words and multimorphemic words were matched to their definitions. Two studies are reported, one focusing on English placement levels and a second with formal measures of both ASL and English language proficiency. Results in-dicated that performance on the morphological decoding test was related to language proficiency scores, but not to phonological awareness scores.

Consciência fonológica e habilidades de escrita em crianças com síndrome de Down

Down syndrome, phonological awareness, writing and working memory. to evaluate the phonological awareness of Brazilian children with Down syndrome; to analyze the relationship between the writing hypothesis and the phonological awareness scores of the participants; to compare the performance of children with Down syndrome to that of children with typical development according to the Phonological Awareness: Tool for sequential evaluation (PHONATSE), using the writing hypothesis as a matching criteria; to verify the correlation between the phonological awareness measurements and the phonological working memory. a group of eleven children aged between 7 and 14 years (average: 9 y 10 m) was selected for the study. Phonological awareness was evaluated using the PHONATSE. The phonological working memory was evaluated through an instrument developed by the researcher. all subjects presented measurable levels of phonological awareness through the PHONATSE. The phonological awareness scores and the writing hypothesis presented a significant positive association. The performance of children with Down syndrome was significantly lower than children with typical development who presented the same writing hypothesis. Measurements of phonological awareness and phonological working memory presented significant positive correlations. the phonological awareness of Brazilian children with Down syndrome can be evaluated through the PHONATSE. Syllable awareness improves with literacy, whereas phonemic awareness seems to result from written language learning. The phonological working memory influences the performance of children with Down syndrome in phonological awareness tasks.

Categorical speech perception deficits distinguish language and reading impairments in children

We examined categorical speech perception in school-age children with developmental dyslexia or Specific Language Impairment (SLI), compared to age-matched and younger controls. Stimuli consisted of synthetic speech tokens in which place of articulation varied from 'b' to 'd'. Children were tested on categorization, categorization in noise, and discrimination. Phonological awareness skills were also assessed to examine whether these correlated with speech perception measures. We observed similarly good baseline categorization rates across all groups; however, when noise was added, the SLI group showed impaired categorization relative to controls, whereas dyslexic children showed an intact profile. The SLI group showed poorer than expected between-category discrimination rates, whereas this pattern was only marginal in the dyslexic group. Impaired phonological awareness profiles were observed in both the SLI and dyslexic groups; however, correlations between phonological awareness and speech perception scores were not significant. The results of the study suggest that in children with language and reading impairments, there is a significant relationship between receptive language and speech perception, there is at best a weak relationship between reading and speech perception, and indeed the relationship between phonological and speech perception deficits is highly complex.

Literacy skills in children with cochlear implants: the importance of early oral language and joint storybook reading.

The goal of this study was to longitudinally examine relationships between early factors (child and mother) that may influence children's phonological awareness and reading skills 3 years later in a group of young children with cochlear implants (N = 16). Mothers and children were videotaped during two storybook interactions, and children's oral language skills were assessed using the "Reynell Developmental Language Scales, third edition." Three years later, phonological awareness, reading skills, and language skills were assessed using the "Phonological Awareness Test," the "Woodcock-Johnson-III Diagnostic Reading Battery," and the "Oral Written Language Scales." Variables included in the data analyses were child (age, age at implant, and language skills) and mother factors (facilitative language techniques) and children's phonological awareness and reading standard scores. Results indicate that children's early expressive oral language skills and mothers' use of a higher level facilitative language technique (open-ended question) during storybook reading, although related, each contributed uniquely to children's literacy skills. Individual analyses revealed that the children with expressive standard scores below 70 at Time 1 also performed below average (<85) on phonological awareness and total reading tasks 3 years later. Guidelines for professionals are provided to support literacy skills in young children with cochlear implants.

Predictors of Grade 2 Word Reading and Vocabulary Learning from Grade 1 Variables in Spanish‐Speaking Children: Similarities and Differences

We examined the components of first (L1) and second language (L2) phonological processing that are related to L2 word reading and vocabulary. Spanish‐speaking English learners (EL) were classified as average or low readers in grades 1 and 2. A large number of children who started out as poor readers in first grade became average readers in second grade while vocabulary scores were more stable. Binary logistic regressions examined variables related to classifications of consistently average, consistently low, or improving on reading or vocabulary across grades. Good L2 phonological short‐term memory and phonological awareness scores predicted good reading and vocabulary scores. L1 and L2 measures differentiated consistently good performers from consistently low performers, while only L2 measures differentiated children who improved from children who remained low performers. Children who are EL should be screened on measures of pseudoword repetition and phonological awareness with low scorers being good candidates for receiving extra assistance in acquiring L2 vocabulary and reading. This study suggests measures that can be used to select children who have a greater likelihood of experiencing difficulties in reading and vocabulary.
