Phonological Processing Skills and Early Reading Abilities in Hong Kong Chinese Kindergarteners Learning to Read English as a Second Language.

The present 9-month longitudinal study investigated relations between Chinese native language phonological processing skills and early Chinese and English reading abilities among 227 kindergarteners in Hong Kong. Phonological awareness, rapid automatized naming, and short-term verbal memory differed in their relations to concurrent and subsequent Chinese and English word recognition. The significant bidirectional relations between phonological awareness and Chinese reading ability remained even after accounting for the variance due to age, vocabulary, and visual skills performance. When all predictors were considered simultaneously, only phonological awareness remained a significant predictor of Chinese and English reading abilities both concurrently and longitudinally.

Specific contributions of phonological abilities to early reading acquisition: Results from a Dutch latent variable longitudinal study.

Contributions of phonological abilities to early reading acquisition were examined in a longitudinal study of 166 Dutch children from kindergarten through 2nd grade. Various phonological abilities, nonverbal intelligence, vocabulary, and letter knowledge were assessed in kindergarten and Grade 1. Reading and arithmetic were examined in 1st and 2nd grades. The importance of individual differences in phonological ability for subsequent reading acquisition changed over time. At first, the effects of phonological abilities increased, but after Grade 1, these effects disappeared. Phonological awareness and rapid naming had independent and specific influences on reading achievement. Verbal working memory was associated with both reading and arithmetic acquisition. The results tend to support an interactive view of the relation between development of phonological abilities and learning to read. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development of reading-related phonological processing abilities: New evidence of bidirectional causality from a latent variable longitudinal study.

Results from a longitudinal correlational study of 244 children from kindergarten through 2nd grade indicate that young children's phonological processing abilities are well-described by 5 correlated latent abilities: phonological analysis, phonological synthesis, phonological coding in working memory, isolated naming, and serial naming. These abilities are characterized by different developmental rates and remarkably stable individual differences. Decoding did not exert a causal influence on subsequent phonological processing abilities, but letter-name knowledge did. Causal relations between phonological processing abilities and reading-related knowledge are bidirectional: Phonological processing abilities exert strong causal influences on word decoding; letter-name knowledge exerts a more modest causal influence on subsequent phonological processing abilities.

Kindergarten Prediction of Reading Skills: A Longitudinal Comparative Analysis.

There is considerable focus in public policy on screening children for reading difficulties. Sixty years of research have not resolved questions of what constructs assessed in kindergarten best predict subsequent reading outcomes. This study assessed the relative importance of multiple measures obtained in a kindergarten sample for the prediction of reading outcomes at the end of 1st and 2nd grades. Analyses revealed that measures of phonological awareness, letter sound knowledge, and naming speed consistently accounted for the unique variance across reading outcomes whereas measures of perceptual skills and oral language and vocabulary did not. These results show that measures of letter name and letter sound knowledge, naming speed, and phonological awareness are good predictors of multiple reading outcomes in Grades 1 and 2.

Subtypes of reading disability: Variability around a phonological core.

Eight measures of cognitive and language functions in 232 children were subjected to multiple methods of cluster analysis in an effort to identify subtypes of reading disability. Clustering yielded 9 reliable subtypes representing 90% of the sample, including 2 nondisabled subtypes, and 7 reading-disabled subtypes. Of the reading-disabled subtypes, 2 were globally deficient in language skills, whereas 4 of the 5 specific reading-disabled subtypes displayed a relative weakness in phonological awareness and variations in rapid serial naming and verbal short-term memory. The remaining disabled subtype was impaired on verbal and nonverbal measures associated with rate of processing, including rate and accuracy of oral reading. Studies showed evidence for discriminative validity among the 7 reading-disabled subtypes. Results support the view that children with reading disability usually display impairments on phonological awareness measures, with discriminative variability on other measures involving phonological processing, language, and cognitive skills.

Prediction of reading disability from familial and individual differences.

Reading ability at Grade 2 was well predicted both by the incidence of reading problems in children's families and by individual differences among the children in vocabulary, phonological awareness, and early literacy skills at age 5 years. In contrast, sex, socioeconomic status (SES), age, and preschool differences in IQ, nonverbal skills, early education, and reading and television-viewing habits were unrelated to subsequent reading acquisition. Greater accuracy of prediction was obtained when test results rather than self-reports were used to determine familial reading problems, but little support was found for the utility or reliability of a distinction between low achievement in reading and specific underachievement relative to IQ in prediction analyses.

Speech perception, vocabulary, and the development of reading skills in english among Korean- and English-speaking children.

This study examined the roles of speech perception and phonological processing in reading and spelling acquisition for native and nonnative speakers of English in the 1st grade. The performance of 50 children (23 native English speakers and 27 native Korean speakers) was examined on tasks assessing reading and spelling, phonological processing, speech perception, and receptive vocabulary at the start and end of the school year. Korean-speaking children outperformed native English speakers on each of the literacy measures at the start and end of 1st grade, despite differences in their initial phonological representations and processing skills. Furthermore, speech perception and phonological processing were important contributors to early literacy skills, independent of oral language skills, for children from both language groups.

A longitudinal study of phonological processing skills in children learning to read in a second language.

English-speaking children (N?=?122) in French immersion classes participated in a 1-year longitudinal study of the relation between phonological awareness and reading achievement in both languages. Participants were administered measures of word decoding and of phonological awareness in French and in English as well as measures of cognitive ability, speeded naming, and pseudoword repetition in English only. The relation of phonological awareness in French to reading achievement in each of the languages was equivalent to that in English. These relations remained significant after partialing out the influences of speeded naming and pseudoword repetition. Phonological awareness in both languages was specifically associated with 1-year increments in decoding skill in French. These findings support the transfer of phonological awareness skills across alphabetic languages. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Understanding chinese developmental dyslexia: Morphological awareness as a core cognitive construct.

Tasks representing 9 cognitive constructs of potential importance to understanding Chinese reading development and impairment were administered to 75 children with dyslexia and 77 age-matched children without reading difficulties in 5th and 6th grade. Logistic regression analyses revealed that dyslexic readers were best distinguished from age-matched controls with tasks of morphological awareness, speeded number naming, and vocabulary skill; performance on tasks of visual skills or phonological awareness failed to distinguish the groups. Path analyses further revealed that a construct of morphological awareness was the strongest consistent predictor of a variety of literacy-related skills across both groups. Findings suggest that morphological awareness may be a core theoretical construct necessary for explaining variability in reading Chinese.

Developmental issues in Chinese children's character acquisition.

Measures of phonological processing, speech perception, and Chinese character recognition were administered to 109 Hong Kong Chinese 3- and 4-year-olds. A model predicting phonological awareness from vocabulary, verbal short-term memory, and speech perception was supported. Both phonological awareness and letter naming predicted unique variance in character recognition after controlling for other phonological processing and vocabulary skills, similar to previous studies of Western readers.

Cross-sectional and incremental changes in working memory and mathematical problem solving.

Cross-sectional and incremental age effects on cognitive processes that underlie individual differences in components of working memory (WM; phonological loop, visual-spatial sketchpad, executive processing) and mathematical problem-solving accuracy were examined in elementary schoolchildren. A battery of tests was administered that assessed problem solving, achievement, memory, and cognitive processing (inhibition, speed, phonological coding) in children in Grades 1, 2, and 3 (Wave 1) and 1 year later (Wave 2). The results showed that (a) 31% of the explainable within-person changes across testing waves and 42% of the age-related differences in word problem-solving accuracy were related to executive processing and (b) executive processing and reading performance in Year 1 were the only variables that contributed unique variance to Year 2 problem-solving performance. The results support the notion that growth in the executive system is an important predictor of children's problem solving abilities beyond the contribution of reading and calculation skills and that growth in executive processing can operate independently of individual differences in phonological processing, inhibition, and processing speed.

Home literacy activities and their influence on early literacy skills.

The relationship between the home environments of 66 children (aged 5.4–6.7 yrs) and their language and literacy development was examined. Parents (aged 28–46 yrs) of the children were interviewed regarding demographic information and home visits were conducted in which parents were observed reading with their children and interviewed about specific literacy practices. Children were assessed at approximately 9 mo intervals. After accounting for child age, parent education, and child ability as indexed by scores on a rapid automatized naming task and Block Design of the Wechsler Preschool and Primary Scales of Intelligence—Revised, shared book reading at home made no contribution to the prediction of the literacy skills of letter name and letter sound knowledge in kindergarten. In contrast, home activities involving letters predicted modest and significant amounts of variance. For the areas of receptive vocabulary and phonological sensitivity, neither shared book reading nor letter activities were predictive. Follow-up to mid-Grade 2 underscored the importance of letter name/sound knowledge and phonological sensitivity in kindergarten in accounting for individual differences in later achievement in reading comprehension, phonological spelling and conventional spelling.

Speech perception, metalinguistic awareness, reading, and vocabulary in Chinese–English bilingual children.

In this study, we examined the intercorrelations among speech perception, metalinguistic (i.e., phonological and morphological) awareness, word reading, and vocabulary in a 1st language (L1) and a 2nd language (L2). Results from 3 age groups of Chinese–English bilingual children showed that speech perception was more predictive of reading and vocabulary in the L1 than L2. While morphological awareness uniquely predicted reading and vocabulary in both languages, phonological awareness played such a role after we controlled for morphological awareness only in the L2, which was alphabetic. L1 speech perception and metalinguistic awareness predicted L2 word reading but not vocabulary, after we controlled for the corresponding L2 variables. Hence, there are both similarities and differences between the 2 languages in how the constructs are related. The differences are attributable to variations in language properties and learning contexts. Implications of the present results for an effective L2 learning program are discussed.

Socioeconomic status differences in preschool phonological sensitivity and first-grade reading achievement.

Two groups of 5-yr-old children whose fathers' occupations differed markedly in education and skill levels were seen in preschool, where they were given tests of performance IQ, receptive vocabulary and grammar, verbal working memory, phonological sensitivity, letter knowledge, and novice reading ability. At the end of 1st Grade, academic achievement was assessed. Marked group differences were observed on most measures. Most differences remained after performance IQ effects were controlled. When general verbal ability effects were controlled, differences in phonological sensitivity and word-level reading and arithmetic achievement remained. When phonological sensitivity effects were also controlled, differences remained only in arithmetic performance. The same general pattern of results was observed in converging hierarchical multiple regression analyses. Overall, the results are consistent with the view that SES differences in word-level reading achievement are mediated partly through preexisting differences in phonological sensitivity.

Predictors of reading and spelling abilities in first- and second-language learners.

This study examined the basic literacy skills and related processes of 1st- through 4th-grade children speaking English as a 1st language (L1) and English as a 2nd language (ESL). The performances of the L1 and ESL children on phonological awareness, word and pseudoword reading, and word and pseudoword spelling tasks were highly similar. The ESL children were at an advantage with regard to lexical access but performed more poorly on verbal working memory and syntactic awareness tasks. The results suggest that the main processes underlying L1 children's basic reading ability in Grades 1 and 2, namely phonological awareness and lexical access, are of equal importance for ESL children. Phonological awareness remained the strongest predictor of word reading ability for L1 and ESL children in Grades 3 and 4. However, the processes involved in L1 and ESL word reading and spelling appeared to vary at other points. Verbal working memory and syntactic awareness were found to be of importance for the word reading and spelling abilities of L1 children but not for ESL children. Lexical access was found to be of more importance for ESL children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The nature of phonological processing and its causal role in the acquisition of reading skills.

Three bodies of research that have developed in relative isolation center on each of three kinds of phonological processing: phonological awareness, awareness of the sound structure of language; phonological recoding in lexical access, recoding written symbols into a sound-based representational system to get from the written word to its lexical referent; and phonetic recoding in working memory, recoding written symbols into a sound-based representation system to maintain them efficiently in working memory. In this review we integrate these bodies of research and address the interdependent issues of the nature of phonological abilities and their causal roles in the acquisition of reading skills. Our review supports a causal role for phonological awareness in learning to read, and suggests the possibility of similar causal roles for phonological recoding in lexical access and phonetic recoding in working memory. Most researchers have neglected the probable causal role of learning to read in the development of phonological skills. It is no longer enough to ask whether phonological skills play a causal role in the acquisition of reading skills. The question now is which aspects of phonological processing (e.g., awareness, recoding in lexical access, recoding in working memory) are causally related to which aspects of reading (e.g., word recognition, word analysis, sentence comprehension), at which point in their codevelopment, and what are the directions of these causal relations?

Does growth rate in oral reading fluency matter in predicting reading comprehension achievement?

In this study, we examined the relationship of growth trajectories of oral reading fluency, vocabulary, phonological awareness, letter-naming fluency, and nonsense word reading fluency from 1st grade to 3rd grade with reading comprehension in 1st, 2nd, and 3rd grades. Data from 12,536 children who were followed from kindergarten to 3rd grade longitudinally were used. These children were administered Dynamic Indicators of Basic Early Literacy Skills subtests, Peabody Picture Vocabulary Test—Third Edition, and reading comprehension (Stanford Achievement Test, 10th ed.) tasks multiple times in each year. Students' initial status and rate of growth in each predictor within each grade were estimated using individual growth modeling. These estimates were then used as predictors in dominance regression analyses to examine relative contributions that the predictors made to the outcome: reading comprehension. Among the 1st-grade predictors, individual differences in growth rate in oral reading fluency in 1st grade, followed by vocabulary skills and the autoregressive effect of reading comprehension, made the most contribution to reading comprehension in 3rd grade. Among the 2nd- and 3rd-grade predictors, children's initial status in oral reading fluency had the strongest relationships with their reading comprehension skills in 3rd grade.

The nature of preschool phonological processing abilities and their relations to vocabulary, general cognitive abilities, and print knowledge.

The development of reading-related phonological processing abilities represents an important developmental milestone in the process of learning to read. In this cross-sectional study, confirmatory factor analysis was used to examine the structure of phonological processing abilities in 129 younger preschoolers (M = 40.88 months, SD = 4.65) and 304 older preschoolers (M = 56.49 months, SD = 5.31). A 2-factor model in which Phonological Awareness and Phonological Memory were represented by 1 factor and Lexical Access was represented by a 2nd factor provided the best fit for both samples and was largely invariant across samples. Measures of vocabulary, cognitive abilities, and print knowledge were significantly correlated with both factors, but Phonological Awareness/Memory had unique relations with word reading. Despite significant development of phonological processing abilities across the preschool years and into kindergarten, these results show that the structure of these skills remains invariant.
