Phonological awareness and reading acquisition in English- and Punjabi-speaking Canadian children.

This study examined whether the same component processes are involved in reading acquisition for native and nonnative speakers of English in the 1st grade. The performance of 88 children was examined on tasks assessing reading skill, phonological processing, and syntactic awareness. Fifty children were native English speakers (L1), and 38 children were from Punjabi-speaking families (ESL). Although measures of word recognition and phonological processing successfully discriminated between average and poor readers, they did not discriminate between the 2 language groups. Analyses of word reading errors revealed similar error patterns for ESL and L1 children, yet different error patterns for average and poor readers. For both L1 and ESL children, reading difficulties appear to be strongly linked with impaired phonological processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Enhancing the reading of dyslexic children by reading acceleration and auditory masking.

This research attempted to improve the reading performance of dyslexic children through two different methods: reading acceleration and auditory masking. Participants were 52 dyslexic children and 52 reading-level matched normal, novice readers. Results indicated that whereas acceleration improved reading performance in both groups, auditory masking was beneficial to dyslexic children only. Furthermore, a combined condition of both acceleration and masking was the most effective in enhancing dyslexic children's comprehension. It is argued that because normal readers use the phonological route quite effectively, its masking is detrimental to performance. On the other hand, auditory masking reduces the impact of the presumed phonological impairment of dyslexic children. Analysis of decoding mistakes suggested that both manipulations might have resulted in a more effective utilization of orthographic information and enhanced top-down context effects for dyslexic and novice readers.

Changing relations between phonological processing abilities and word-level reading as children develop from beginning to skilled readers: A 5-year longitudinal study.

Relations between phonological processing abilities and word-level reading skills were examined in a longitudinal correlational study of 216 children. Phonological processing abilities, word-level reading skills, and vocabulary were assessed annually from kindergarten through 4th grade, as the children developed from beginning to skilled readers. Individual differences in phonological awareness were related to subsequent individual differences in word-level reading for every time period examined. Individual differences in serial naming and vocabulary were related to subsequent individual differences in word-level reading initially, but these relations faded with development. Individual differences in letter-name knowledge were related to subsequent individual differences in phonological awareness and serial naming, but there were no relations between individual differences in word level reading and any subsequent phonological processing ability.

Development of word reading fluency and spelling in a consistent orthography: An 8-year follow-up.

In a longitudinal study, development of word reading fluency and spelling were followed for almost 8 years. In a group of 115 students (65 girls, 50 boys) acquiring the phonologically transparent German orthography, prediction measures (letter knowledge, phonological short-term memory, phonological awareness, rapid automatized naming, and nonverbal IQ) were assessed at the beginning of Grade 1; reading fluency and spelling were tested at the end of Grade 1 as well as in Grades 4 and 8. Reading accuracy was close to ceiling in all reading assessments, such that reading fluency was not heavily influenced by differences in reading accuracy. High stability was observed for word reading fluency development. Of the dysfluent readers in Grade 1, 70% were still poor readers in Grade 8. For spelling, children who at the end of Grade 1 still had problems translating spoken words into phonologically plausible letter sequences developed problems with orthographic spelling later on. The strongest specific predictors were rapid automatized naming for reading fluency and phonological awareness for spelling. Word recognition speed was a relevant and highly stable indicator of reading skills and the only indicator that discriminated reading skill levels in consistent orthographies. Its long-term development was more strongly influenced by early naming speed than by phonological awareness. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Phenotypic performance profile of children with reading disabilities: A regression-based test of the phonological-core variable-difference model.

Introduces a new analytic strategy for comparing the cognitive profiles of children developing reading skills at different rates: a regression-based logic analogous to the reading-level match design, but without some of the methodological problems of that design. It provides a unique method for examining whether the reading subskill profiles of poor readers with aptitude/achievement discrepancy differ from those without discrepancy. 907 children (aged 7–16 yrs) were compared on a varied set of phonological, orthographic, memory, and language processing tasks. The results indicated that cognitive differences between these 2 groups of poor readers all reside outside of the word recognition module. The results generally support the phonological-core variable-difference model of reading disability and demonstrate that degree of aptitude/achievement discrepancy is unrelated to the unique cognitive tradeoffs that are characteristic of the word recognition performance of children with reading disabilities.

A longitudinal study of reading development in dyslexic children.

The development of literacy skills was studied in 20 dyslexic children (7 years 7 months to 12 years 7 months). At Time 1, the dyslexic children performed worse on tests of reading, spelling, and phonological processing than chronological age-matched normal readers, but their performance was qualitatively similar to that of younger reading age-matched controls. The dyslexic children made poor progress over the following 2 years and, in comparison with reading age controls at Time 2, showed specific difficulties in nonword reading and repetition and made more dysphonetic spelling errors. The authors argue that this typical dyslexic profile becomes more defined with development and provides support for the theory that phonological deficits in dyslexia compromise the development of reading skills.

Cognitive profiles of difficult-to-remediate and readily remediated poor readers: Early intervention as a vehicle for distinguishing between cognitive and experiential deficits as basic causes of specific reading disability.

Reading impaired first graders were given daily tutoring as a "first cut" diagnostic to aid in distinguishing between reading difficulties caused by basic cognitive deficits and those caused by experiential deficits. Reading achievement in most of these children was found to be within or above the average range after one semester of remediation. Children who were difficult to remediate performed below both children who were readily remediated and normal readers on kindergarten and first-grade tests evaluating phonological skills, but not on tests evaluating visual, semantic and syntactic skills. The results are consistent with convergent findings from previous research suggesting that reading problems in some poor readers may be caused primarily by phonological deficits.

Reading comprehension and working memory in learning-disabled readers: Is the phonological loop more important than the executive system?

This investigation explores the contribution of two working memory systems (the articulatory loop and the central executive) to the performance differences between learning-disabled (LD) and skilled readers. Performances of LD, chronological age (CA) matched, and reading level-matched children were compared on measures of phonological processing accuracy and speed (articulatory system), long-term memory (LTM) accuracy and speed, and executive processing. The results indicated that (a) LD readers were inferior on measures of articulatory, LTM, and executive processing; (b) LD readers were superior to RL readers on measures of executive processing, but were comparable to RL readers on measures of the articulatory and LTM system; (c) executive processing differences remained significant between LD and CA-matched children when measures of reading comprehension, articulatory processes, and LTM processes were partialed from the analysis; and (d) executive processing contributed significant variance to reading comprehension when measures of the articulatory and LTM systems were entered into a hierarchical regression model. In summary, LD readers experience constraints in the articulatory and LTM system, but constraints mediate only some of the influence of executive processing on reading comprehension. Further, LD readers suffer executive processing problems nonspecific to their reading comprehension problems.     

The /O/ in OVER is different from the /O/ in OTTER: Phonological effects in children with and without dyslexia.

First-letter naming was used to investigate the role of phonology in printed word perception in children with and without dyslexia. In 2 experiments, all children showed faster first-letter-naming times in a congruent condition than in an incongruent condition, which suggests that phonology is a fundamental constraint in the printed word perception of readers of all levels and all skills. An explanation in terms of a recurrent network put forward by G. C. Van Orden and S. D. Goldinger (1996) is discussed to account for the apparent paradox in the reading behavior of readers with dyslexia, that is, that in first-letter naming, dyslexic readers appear to show phonological congruity effects, whereas in pseudoword reading, their phonological knowledge appears to be deficient or absent.

Persistence of dyslexics' phonological awareness deficits.

Examined the phonological awareness skills of dyslexic children, adults with childhood diagnoses of dyslexia, and good readers at various age levels. Comparisons of the dyslexics to good readers of the same age or the same reading level indicated that dyslexics do not acquire appropriate levels of phoneme awareness, regardless of their age or reading levels, although they eventually acquire appropriate levels of onset-rhyme awareness. Even adults with fairly high levels of word recognition skill show phoneme awareness deficits. For normal readers, reliable increases in phoneme awareness were associated with age and reading level, whereas for dyslexic Ss these associations were not reliable.

Gastrointestinal manifestations in pediatric AIDS

Current debate over the influence of phonological awareness on early reading development is polarised around small-unit (phoneme) processing and large-unit (onset-rime) processing. These opposing theories were contrasted by assessing the impact of pre-school phonological skills on reading amongst children experiencing their first year of formal instruction by a mixed method. Those beginning readers who could decode nonwords were found to have accomplished this by employing their letter-sound knowledge rather than by making analogies based on familiar rime units. Children displayed this pattern of performance regardless of their pre-school rhyming skills. Further investigations revealed that explicit awareness of onset and rime units was poor, even amongst children whose implicit rhyming skills were excellent. This evidence, together with the children's knowledge of orthographic units, was consistent with the view that letter-sound correspondences rather than onset or rime units formed the basis of their first attempts to utilise phonology in reading. The findings are discussed with reference to instructional influences on early reading and phonological awareness.     

Early Development of Neurophysiological Processes Involved in Normal Reading and Reading Disability: A Magnetic Source Imaging Study.

This longitudinal study examined the development of the brain mechanism involved in phonological decoding in beginning readers using magnetic source imaging. Kindergarten students were assigned to 2 groups: those who showed mastery of skills that are important predictors of proficient reading (low-risk group) and those who initially did not show mastery but later benefited from systematic reading instruction and developed average-range reading skills at the end of Grade 1 (high-risk responders). Spatiotemporal profiles of brain activity were obtained during performance of letter-sound and pseudoword naming tasks before and after Grade 1 instruction. With few exceptions, low-risk children showed early development of brain activation profiles that are typical of older skilled readers. Provided that temporoparietal and visual association areas were recruited into the brain mechanism that supported reading, the majority of high-risk responder children benefited from systematic reading instruction and developed adequate reading abilities.

Cognitive processing deficits in poor readers with symptoms of reading disabilities and ADHD: More alike than different?

The cognitive differences among poor-reading children with characteristics of reading disabilities (RD) and attention deficit-hyperactivity disorder (ADHD) when compared with children with comorbid symptoms (RD + ADHD) and slow learners (SL) on measures of phonological and executive processing were investigated. No significant differences in performance emerged between the ability groups in phonological processing. The SL + ADHD & slow learners performed better than RD groups (RD alone and RD + ADHD) on the visual-spatial working memory (WM) factor score and the RD-alone group was inferior to RD + ADHD, SL + ADHD, and SL-alone groups on the verbal WM factor score. The results support the notion that poor readers, whether suffering from RD or ADHD symptoms, share a common phonological core deficit.

Phonological skills are important in learning to read Chinese.

A4-year longitudinal study was conducted to examine the relationship between Chinese children's phonological skills and their success in reading. Initially, 100 Hong Kong Chinese children were tested on visual and phonological skills at the age of 3, before they could read. The findings showed that prereading phonological skills significantly predicted the children's reading performance in Chinese 2 and 3 years later, even after controlling for the effects of age, IQ, and mother's education. The main reason for this relationship is that phonological knowledge helps children to use the phonetic component in Chinese characters.

The nonword-reading deficit of disabled readers: A developmental interpretation.

This article presents empirical evidence challenging the received wisdom that a nonword-reading deficit is a characteristic trait of disabled readers. On the basis of 2 large-scale empirical studies using the reading-level match design, we argue that a nonword-reading deficit is the consequence of normal developmental differences in word-specific knowledge between disabled readers and younger normal readers (both groups being matched on real-word reading). The first study shows that the nonword-reading deficit varies as a function of age and reading level and that this deficit is not typical for disabled readers. The second study demonstrates that a nonword-reading deficit crucially depends on the sensitivity of the matching word reading task to detect age-related differences in word-specific knowledge between disabled and normal readers. We clarify how these findings can be interpreted within the current framework of the phonological deficit hypothesis and discuss implications for theories of reading development.

The cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia.

The present study was conducted to examine the cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia. Thirty Chinese dyslexic children in Hong Kong were compared with 30 average readers of the same chronological age (CA controls) and 30 average readers of the same reading level (RL controls) in a number of rapid naming, visual, phonological, and orthographic tasks. Chinese dyslexic children performed significantly worse than the CA controls but similarly to the RL controls on most of the cognitive tasks. The rapid naming deficit was found to be the most dominant type of cognitive deficit in Chinese dyslexic children. Over half of the dyslexic children exhibited deficits in 3 or more cognitive areas, and there was a significant association between the number of cognitive deficits and the degree of reading and spelling impairment. The present findings support the multiple-deficit hypothesis in Chinese developmental dyslexia. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cross-language transfer of phonological awareness.

Investigated the factors influencing the English word identification performance of Spanish-speaking beginning readers. Beginning readers were administered tests of letter naming, Spanish phonological awareness, Spanish and English word recognition, and Spanish and English oral proficiency. Multiple-regression analyses revealed that the readers' performance on English word and pseudoword recognition tests was predicted by the levels of both Spanish phonological awareness and Spanish word recognition, thus indicating cross-language transfer. In contrast, neither English nor Spanish oral proficiency affected word-identification performance. Results suggest a specific way in which 1st-language learning and experience can aid children in the beginning stages of reading. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Print exposure as a predictor of word reading and reading comprehension in disabled and nondisabled readers.

The relation of print exposure, measured by a revised version of A. E. Cunningham and K. E. Stanovich's (1990) Title Recognition Test (TRT), to word reading and reading comprehension was examined in disabled and nondisabled readers, Grades 5–9. In disabled readers, the TRT was a significant predictor of word reading when phonological skill was accounted for but not when orthographic ability was added to the regression equation, suggesting that the TRT overlaps considerably with orthographic skill. The TRT significantly predicted nondisabled readers' word reading after both phonological and orthographic skills were accounted for. The TRT contributed significantly to reading comprehension once variance was partialed from higher order reading processes for disabled readers only. The TRT's power to predict comprehension may be ascribed to the effects of print exposure on automaticity of word recognition, knowledge, or familiarization with text structure.

Contextual effects on reading aloud: Evidence for pathway control.

Recent evidence suggests that the processes responsible for generating a phonological code from print are flexible in skilled readers. An important goal, therefore, is to identify the conditions that lead to changes in how a phonological code is computed. Five experiments are reported that examine whether phonological processes change as predicted by the pathway control hypothesis when reading aloud words and nonwords. Changes in reading processes were assessed by measuring the effect of predictable switches between stimulus categories across trials. The results of the present experiments are argued to be consistent with the pathway control hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive processes as predictors of word recognition and reading comprehension in learning-disabled and skilled readers: Revisiting the specificity hypothesis.

Examines how cognitive processes interrelate as well as predict learning-disabled (LD) readers' word recognition and reading comprehension performance. Correlations between phonological, orthographic, semantic, metacognitive, and working memory measures with reading performance were examined in LD and skilled readers (aged 8–12 yrs). LD Ss were deficient on all cognitive processes compared with skilled Ss, but these differences do not reflect IQ scores. Reading ability group differences emerged on a component composed primarily of working memory measures (referred to as "g") as well as unique components, suggesting that these differences emerge on both general and specific (modular) processes. G best predicts reading comprehension for both groups, and phonological awareness best predicts skilled Ss' pseudoword reading, whereas g best predicts LD Ss' pseudoword performance. Overall, LD Ss' information processing difficulties were described within a general working memory model that views such children as having difficulty accessing and coordinating both general and specific processes. Results suggest that the cognitive processes that contribute to reading deficits are best understood in the context of their combination with other operations rather than in isolation.
