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.

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)     

The structure of genetic influences on general cognitive, language, phonological, and reading abilities.

The etiology of individual differences in literacy, phonological awareness, and language ability is reported in 126 pairs of monozygotic and dizygotic twins. At age 6 and 7 years, more than 60% of the variance in literacy was heritable. Heritabilities for 6- and 7-year-olds were .52 and .62, respectively, for phonological awareness and .43 and .50, respectively, for language ability. After genetic effects on IQ were controlled, a separate genetic influence was identified that acted on literacy, phonological awareness, and language. No genetic link between phonological awareness and literacy independent of general language ability was found; such covariance was mediated through environmental influences. Individual differences in literacy ability are substantially influenced by genetic factors, some of which also act on phonological awareness and general language ability.

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.

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.

Development of grammatical-sensitivity, phonological, and short-term memory skills in normally achieving and learning disabled children.

The development of a variety of grammatical-sensitivity and phonological skills was studied in 138 normally achieving, 65 reading-disabled, 63 arithmetic-disabled, and 15 attention deficit disordered (hyperactive) children 7 to 14 years old. Word recognition and phonics skills were highly related, and reading comprehension and phonics skills were less so. Grammatical sensitivity and short-term memory were significantly correlated with a variety of reading skills. Children with a reading disability showed a significant lag in the development of grammatical sensitivity and short-term memory and an even greater deficit in phonological skills. The children with a specific arithmetic disability had adequate grammatical abilities, but below-average memory skills at all ages. Children with an attention deficit but normal achievement scores did not have any major difficulties except on a reading-comprehension task that appears to have significant memory and attention components. The acquisition of reading skills is closely related to the development of grammatical and phonological skills, and deficiencies in these areas are related to difficulties with the acquisition of written language skills.

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.

Whole word, frequency-general phonology in semantic processing of Chinese characters.

Two experiments were conducted to examine the locus of the phonological and semantic interference effects in Chinese reported by C. A. Perfetti and S. Zhang (see record 1995-20076-001). Both experiments found that phonological effects in semantic judgments were general across word frequency and independent of component phonology, thus localizing phonological interference at the whole-character level. However, effects of component phonology were obtained for low-frequency characters when pronunciation judgments were made. The results are consistent with the assumption that phonology is activated at 2 levels in Chinese reading, 1 at the whole character level and 1 at the phonetic component level. A strong semantic interference was also found in both experiments, implying that both phonology and semantics are automatically activated. The constituency model provides a framework to explain the pervasive word-level phonology seen across writing systems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Reading and arithmetic in adolescents with autism spectrum disorders: Peaks and dips in attainment.

In describing academic attainment in autism spectrum disorders (ASD), results are typically reported at the group mean level. This may mask subgroups of individuals for whom academic achievement is incommensurate with intellectual ability. The authors tested the IQ, literacy, and mathematical abilities of a large group (N = 100) of adolescents (14–16 years old) with ASD. Seventy-three percent of the sample had at least one area of literacy or mathematical achievement that was highly discrepant (approximately 14 standard score points) from full-scale IQ (FSIQ). The authors focused on four subgroups with either word reading (“Reading Peak” and “Reading Dip”) or arithmetic (“Arithmetic Peak” and “Arithmetic Dip”) higher or lower than FSIQ. These subgroups were largely mutually exclusive and were characterized by distinct intellectual profiles. The largest was the “Arithmetic Peak” subgroup of participants, who presented with average intellectual ability alongside superior arithmetic skills and who were predominantly in a mainstream educational setting. Overall, the most pervasive profile was discrepantly poor reading comprehension, which associated with severity of social and communication difficulties. The high rate of uneven academic attainment in ASD has implications for educational practice. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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)     

The comprehensive language approach to early literacy: The interrelationships among vocabulary, phonological sensitivity, and print knowledge among preschool-aged children.

This article describes 2 points of view about the relationship between oral-language and literacy skills: The phonological sensitivity approach posits that vocabulary provides the basis for phonological sensitivity, which then is the key language ability supporting reading, and the comprehensive language approach (CLA) posits that varied language skills interact with literacy knowledge and continue to play a vital role in subsequent reading achievement. The study included 533 Head Start preschool-aged children (M=4 years 9 months) in 2 locations and examined receptive vocabulary, phonological awareness, and print knowledge. Partial correlational and regression analyses found results consistent with the CLA approach and evidence of a core deficit in phonological sensitivity, interpreted in a manner consistent with the CLA perspective.

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.

Phonemic segmentation skill and beginning reading.

Investigated the relation of phonological awareness to learning to read in 63 1st-grade children (mean age 6 yrs 2 mo), who were administered tests of verbal intelligence, phonemic segmentation ability, and reading achievement. Verbal intelligence was measured using the PPVT—Form A. Results indicate that the relation of nondigraph word segmentation to reading achievement is greater than that of digraph word segmentation to reading achievement and that this relation is nonlinear. Consistent with the claim of a causal connection between phonological awareness and reading acquisition, a contingency analysis of the data revealed that phonemic segmentation ability is a necessary, but not sufficient, condition for learning to read. The data were also subjected to a path analysis, which indicated that phonological awareness affects reading comprehension indirectly through phonological recoding and that the development of phonological awareness is not greatly affected by method of instruction. Implications of these findings for educational practice are briefly indicated. (36 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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 effects of an adapted interactive writing intervention on kindergarten children's phonological awareness, spelling, and early reading development: A contextualized approach to instruction.

Using a pretest-posttest comparison-group design, this 16-week study investigated the effects of 2 instructional approaches on the phonological awareness, alphabetic knowledge, and early reading of kindergarten children. The primary goal was to compare a form of contextualized instruction based on an adapted interactive writing program with a field-tested program of metalinguistic games. For instructional purposes, the children in each treatment group were divided into small intervention classes, with groupings based on children's common strengths and needs. Each week, these classes met with trained literacy tutors for 4 20-min lessons. Pretest and posttest measures provided data on children's phonological awareness, spelling, and reading development. Statistical analyses of the data indicated no between-groups differences with regard to phonological awareness and spelling achievement. In contrast, results revealed statistically significant differences between the 2 groups on word identification, passage comprehension, and word reading development measures, with the adapted interactive writing group demonstrating greater achievement. These findings verify that the children participating in a contextualized program matched or exceeded the achievement of the children participating in a structured program of metalinguistic games.

Epilepsy in the school aged child: Cognitive-behavioral characteristics and effects on academic performance.

Discusses the cognitive-behavioral and academic functioning of children with epilepsy, the effects of anticonvulsant medications and other peri-ictal phenomena, and their relative impact on cognitive functioning and school achievement. Learning problems often occur in children with epilepsy, with the greatest difficulties in arithmetic, spelling, reading comprehension, and word recognition. Epileptic children also tend to experience more problems in overall achievement, concentration, and mental processing than nonepileptic children. While epileptic children tend to fall within the normal range of IQ, the distribution of their scores is skewed toward the lower level of functioning. Peri-ictal phenomena can effect brain discharges, which can thereby effect concentration, attention, and learning ability. Anticonvulsant medications have potentially negative side effects on neuropsychological functioning as well. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Early prediction of reading achievement with the Sheppard School Entry Screening Test: A four-year longitudinal study.

Administered the Sheppard School Entry Screening Test (SSEST) to 320 kindergarten pupils to examine its ability to predict reading performance in Grades 1, 2, and 3. The 3 SSEST factors (i.e., Figure Drawing, Language, and Perceptual-Motor Skills) were each significantly correlated with reading achievement in all 3 grades, even after correcting for initial IQ. Prediction was much better for pupils with the lowest reading ability. Findings demonstrate the validity of the SSEST as an early indicator of later reading achievement.

Intellectual impairment in children exposed to polychlorinated biphenyls in utero

BACKGROUND: In utero exposure to polychlorinated biphenyls, a ubiquitous environmental contaminant, has been linked to adverse effects on neurologic and intellectual function in infants and young children. We assessed whether these effects persist through school age and examined their importance in the acquisition of reading and arithmetic skills. METHODS: We tested 212 children, recruited as newborns to overrepresent infants born to women who had eaten Lake Michigan fish contaminated with polychlorinated biphenyls. A battery of IQ and achievement tests was administered when the children were 11 years of age. Concentrations of polychlorinated biphenyls in maternal serum and milk at delivery were slightly higher than in the general population. A composite measure of prenatal exposure was derived from concentrations in umbilical-cord serum and maternal serum and milk. RESULTS: Prenatal exposure to polychlorinated biphenyls was associated with lower full-scale and verbal IQ scores after control for potential confounding variables such as socioeconomic status (P = 0.02). The strongest effects related to memory and attention. The most highly exposed children were three times as likely to have low average IQ scores (P <0.001) and twice as likely to be at least two years behind in reading comprehension (P = 0.03). Although larger quantities of polychlorinated biphenyls are transferred by breast-feeding than in utero, there were deficits only in associated with transplacental exposure, suggesting that the developing fetal brain is particularly sensitive to these compounds. CONCLUSIONS: In utero exposure to polychlorinated biphenyls in concentrations slightly higher than those in the general population can have a long-term impact on intellectual function.     

Development of phonological sensitivity in 2- to 5-year-old children.

This study examined phonological sensitivity in 238 children from middle- to upper-income families and 118 children from lower-income families across different levels of linguistic complexity. Children ranged in age from 2 to 5 years. Overall, the results indicated that as children increased in age, phonological sensitivity both increased in absolute terms and became more stable. Significant social class differences in growth of phonological sensitivity were also obtained. Phonological sensitivity at different levels of linguistic complexity (e.g., syllables, phonemes) was substantially interrelated at each age and predicted word reading ability in older children independently of language skills and letter knowledge. These results indicate that phonological sensitivity can be assessed in young preschool children and that lower levels of phonological sensitivity may serve as developmental precursors to higher levels of phonological sensitivity.
