Recent literacy research shows an increasing interest in the influence of prosody on literacy acquisition. The current study examines the relationship of nonspeech rhythmic skills to children's reading acquisition, and their possible relation to stress assignment in Spanish, a syllable‐timed language. Sixty‐six third graders with no reading difficulties were scored on measures of nonspeech rhythm, word‐level decoding skill, reading fluency and reading with correct assignment of lexical stress. After controlling for verbal intelligence and working memory, hierarchical multiple regression analyses showed that nonspeech rhythm predicted unique variance in reading fluency and correct stress assignment; it did not predict decoding skills. Given that Spanish is a syllable‐timed as opposed to stress‐timed language like English, the association between nonspeech rhythm, reading fluency and stress assignment found in our study suggests that nonspeech rhythm may be a universal factor in reading acquisition, independent of the type of linguistic rhythm.  相似文献

A flash card computer program designed to increase decoding speed in reading was evaluated with a sample of 55 eight- to twelve-year-old Dutch poor readers by using a pretest-training-posttest control group design. The reading level of the poor readers was comparable to the reading level of normal readers in grade two. After 8 weeks of practicing (twice a week) for 30 minutes per session, children in the training group showed substantial improvements in decoding speed not only on pseudowords directly practiced during the training, but also in untrained pseudowords and in existing words. The no-training control group did not improve in decoding speed from pre- to posttest. The results, furthermore, indicate that syllable-bound processes play a role in phonological decoding in Dutch, and that the flash card method used in this study stimulates poor readers to decode letter strings into syllabic units, which leads to an increase in decoding speed. The role of the syllable in phonological decoding and the potential of a specific flash card technique as a means to improve decoding skills of poor readers are discussed.  相似文献

Although there is evidence for a close link between the development of oral vocabulary and reading comprehension, less clear is whether oral vocabulary skills relate to the development of word-level reading skills. This study investigated vocabulary and literacy in 81 children aged 8 to 10 years. In regression analyses, vocabulary accounted for unique variance in exception word reading and reading comprehension, but not text reading accuracy, decoding, or regular word reading. Consistent with these data, children with poor reading comprehension exhibited oral vocabulary weaknesses and read fewer exception words correctly. These findings demonstrate that oral vocabulary is associated with some, but not all, reading skills. Results are discussed in terms of current models of reading development.  相似文献

Fifteen children ages 7 to 9 years who had persistent reading difficulties despite adequate instruction were provided with intensive tutorial interventions. The interventions targeted deficient phonological processing and decoding skills for 8 weeks (2 hours per day) followed by an 8-week, 1-hour-per-day intervention that focused on the development of reading fluency skills. Spatiotemporal brain activation profiles were obtained at baseline and after each 8-week intervention program using magnetoencephalography during the performance of an oral sight-word reading task. Changes in brain activity were found in the posterior part of the middle temporal gyrus (Brodmann's Area [BA] 21: increased degree of activity and reduced onset latency), the lateral occipitotemporal region (BA 19/37: decreased onset latency of activation), and the premotor cortex (increased onset latency). Overall changes associated with the intervention were primarily normalizing, as indicated by (a) increased activity in a region that is typically involved in lexical--semantic processing (BA 21) and (b) a shift in the relative timing of regional activity in temporal and frontal cortices to a pattern typically seen in unimpaired readers. These findings extend previous results in demonstrating significant changes in the spatiotemporal profile of activation associated with word reading in response to reading remediation.  相似文献

This study investigated the role of cognitive and language skills as predictors of early literacy skills in children with Specific Language Impairment. A range of cognitive and linguistic skills were assessed in a sample of 137 eight-year-old children with SLI at the beginning of the school year, and 6 months later on word decoding and reading comprehension. The cognitive and linguistic measures revealed four factors that were called language, speech, short-term memory, and phonological awareness. Structural equation modeling showed word decoding to be predicted by speech, short-term memory, and phonological awareness, whereas reading comprehension was predicted by word decoding skills and short-term memory. It can be concluded that in children with SLI variations in early word decoding are mostly determined by speech abilities and short-term memory, and to a lesser extent by phonological awareness. Moreover, reading comprehension turns out to be highly dependent on word decoding and short-term memory.  相似文献

This paper reports a study that followed the development of reading skills in 72 children from the age of 8.5 to 13 years. Each child was administered tests of reading, oral language, phonological skills and nonverbal ability at time 1 and their performance on tests of reading comprehension, word recognition, nonword decoding and exception word reading was assessed at time 2. In addition to phonological skills, three measures of non‐phonological oral language tapping vocabulary knowledge and listening comprehension were unique concurrent predictors of both reading comprehension and word recognition at time 1. Importantly, all three measures of oral language skill also contributed unique variance to individual differences in reading comprehension, word recognition and exception word reading four and a half years later, even when the autoregressive effects of early reading skill were controlled. Moreover, the extent to which a child's word recognition departed from the level predicted from their decoding ability correlated with their oral language skills. These findings suggest that children's oral language proficiency, as well as their phonological skills, influences the course of reading development.  相似文献

This study focuses on the shared variance between reading comprehension and word-level reading skills in a population of 534 Greek children in Grades 2 through 4. The correlations between measures of word and pseudoword accuracy and fluency, on the one hand, and vocabulary and comprehension skills, on the other, were sizeable and stable or increasing with grade. However, the unique contribution of word reading to comprehension became negligible after vocabulary measures were entered in hierarchical regression analyses, particularly for higher grades, suggesting that any effects of decoding on comprehension may be mediated by the lexicon, consistent with lexical quality hypothesis. Structural modeling with latent variables revealed an invariant path across grades in which vocabulary was defined by its covariation with reading accuracy and fluency and affected comprehension directly. It is argued that skilled word reading influences comprehension by strengthening lexical representations, at least when phonological decoding can be relatively effortless.  相似文献

This study examined the heterogeneity within a sample of 140 urban second and third graders identified as at-risk for reading failure due to inefficient word and/or nonword reading. Cluster analyses were conducted using standardized factor scores from a four-factor structural equation model characterizing reading performance in this sample. These standardized factor scores represented performance on four distinct factors: efficiency of word-level skills, text level skills, decoding, and vocabulary. Results identified four clusters of children who show distinctive patterns of performance on the four factors of reading. These understudied groups show different compositions along demographic categories and reading disability categories. Additionally, they have unique instructional needs that call for differentiated instruction in the domains of phonological decoding, fluency, text reading, and vocabulary.  相似文献

Precision Teaching (PT) is an evidence-based intervention, which research indicates is frequently not implemented following training, with few teachers using it in schools after training events. The web-based programme in this research focuses on word-level reading skills and targets blending and segmenting skills rather than whole word reading. This research, undertaken with 10 schools, explored whether a web-based PT programme would provide favourable implementation rates, and support the fidelity of the programme delivery. The study also measured the impact of the PT programme on word decoding and sight word reading using the Test of Word Reading Efficiency. Results suggest favourable implementation rates with 7 of the 10 schools implementing the programme. Full impact data for 34 children suggest that the programme has a positive impact on decoding (effect size 0.7) and sight word reading skills (effect size 0.6). A timed assessment provides evidence that fluency improved as well as accuracy. Gains were sustained at two-month follow-up.  相似文献

It has been hypothesized that students with dyslexia struggle with writing because of a word-level focus that reduces attention to higher level textual features (structure, theme development). This may result from difficulties with spelling and/or difficulties with reading. Twenty-six Norwegian upper secondary students (M = 16.9 years) with weak decoding skills and 26 age-matched controls composed expository texts by keyboard under two conditions: normally and with letters masked to prevent them reading what they were writing. Weak decoders made more spelling errors and produced poorer quality text. Their inter-key-press latencies were substantially longer preword, at word end, and within word. These findings provide some support for the word-level focus hypothesis, although we found that weak decoders were slightly less likely to engage in word-level editing. Preventing reading did not affect differences between weak decoders and controls, indicating that their reduced fluency was associated with production rather than reading difficulties.  相似文献

Very Early Language Deficits in Dyslexic Children   总被引：23，自引：0，他引：23  
At 2 1/2 years of age, children who later developed reading disabilities were deficient in the length, syntactic complexity, and pronunciation accuracy of their spoken language, but not in lexical or speech discrimination skills. As 3-year-olds, these children began to show deficits in receptive vocabulary and object-naming abilities, and as 5-year-olds they exhibited weaknesses in object-naming, phonemic awareness, and letter-sound knowledge that have characterized kindergartners who became poor readers in other studies. These late preschool differences were related to subsequent reading status as well as to prior language skills, but early syntactic proficiency nevertheless accounted for some unique variance in grade 2 achievement when differences at age 5 were statistically controlled. The language deficits of dyslexic children were unrelated to maternal reading ability and were not observed in children from dyslexic families who became normal readers. The implications of the results for etiological issues are discussed.  相似文献

This longitudinal study evaluated the extent to which maternal responsiveness across early childhood and children's cognitive skills predicted children's 8-year decoding and reading comprehension skills for children who varied in biological risk (term, n = 83; preterm, n = 155). Patterns of maternal responsiveness during infancy (6, 12, and 24 months) and preschool (3 and 4 years) revealed 4 maternal clusters that varied in consistency and level of maternal responsiveness. Although not predictive of decoding skills, the interaction between children's 4-year cognitive ability and maternal responsiveness cluster predicted children's reading comprehension skills at 8 years of age, regardless of risk. Although consistently high levels of maternal responsive parenting across early childhood related to literacy outcomes for all children in the study, responsive parenting had a stronger relation to later reading comprehension skills for children with lower cognitive abilities, particularly when mothers demonstrated high responsiveness in children's infancy.  相似文献

We assessed the reading and reading-related skills (phonemic awareness and phonological short-term memory) of deaf children fitted with cochlear implants (CI), either exposed to cued speech early (before 2 years old) (CS+) or never (CS-). Their performance was compared to that of 2 hearing control groups, 1 matched for reading level (RL), and 1 matched for chronological age (CA). Phonemic awareness and phonological short-term memory were assessed respectively through a phonemic similarity judgment task and through a word span task measuring phonological similarity effects. To assess the use of sublexical and lexical reading procedures, children read pseudowords and irregular words aloud. Results showed that cued speech improved performance on both the phonemic awareness and the reading tasks but not on the phonological short-term memory task. In phonemic awareness and reading, CS+ children obtained accuracy and rapidity scores similar to CA controls, whereas CS- children obtained lower scores than hearing controls. Nevertheless, in phonological short-term memory task, the phonological similarity effect of both CI groups was similar. Overall, these results support the use of cued speech to improve phonemic awareness and reading skills in CI children.  相似文献

The purpose of this research was to investigate the cognitive abilities that explain reading comprehension across childhood and early adulthood. Drawing from the standardization sample of the Woodcock–Johnson III, analyses were conducted with large samples at age levels spanning early childhood to early adulthood: 5 to 6 (n = 639), 7 to 8 (n = 720), 9 to 13 (n = 1,995), 14 to 19 (n = 1,615), and 20 to 39 (n = 1,409). Using a model including factors representing general intelligence, Cattell–Horn–Carroll broad abilities, and reading decoding skills, results revealed significant direct effects for reading decoding skills and Crystallized Intelligence on reading comprehension across all age levels. Memory‐related abilities, processing speed, and auditory processing demonstrated indirect effects on reading comprehension through reading decoding skills. The magnitude of direct and indirect effects varied as a function of age. The results provide support for integrative models of reading that include both direct and indirect effects of cognitive abilities on reading comprehension and for consideration of developmental differences in the cognitive aptitudes predicting reading comprehension. © 2012 Wiley Periodicals, Inc.  相似文献

The present study was designed to assess the development of the understanding of certain aspects of grapheme-phoneme correspondences in normally achieving and disabled readers. The correspondences rules were studied using both English words and pseudowords, the latter designed to contain the same features as the real words. The subjects were 76 normally achieving and 32 reading disabled children aged 6 to 14 years. The stimuli included words and pseudowords that tested the following: consonant blends, final e, r-influenced vowels, regular and irregular words, function words, and consistent and inconsistent vowels. When matched for chronological age, the reading disabled children performed significantly more poorly than normally achieving children on all of the tasks involving pseudowords. A similar pattern was found for the words with the exception of the highest frequency words (cvc, final e, consonant blends) at the oldest age level, 11–14 years. In this case, the performance of the oldest reading disabled children was similar to that of the normals on the words, but was still significantly poorer when the stimuli were pseudowords. Complexity and irregularity were significant determinants of difficulty. Comparisons were also made for groups of children matched on reading grade level. Even when the reading disabled and normally achieving children were matched on reading grade, the reading disabled children had significantly more difficulty, particularly with pseudowords. Reading disabled children had significant difficulty in abstracting the basic rules for grapheme-phoneme correspondences in English, and even when they have mastered these rules in connection with real words, they still had difficulty applying these rules to pseudowords. In normal development, the learning of these correspondences appears to be consolidated by approximately 9 years of age. However, reading disabled children appear to have a significant and persistent problem with the learning of basic grapheme-phoneme correspondence rules.  相似文献

Beginning readers in shallow orthographies acquire word reading skills more quickly than in deep orthographies like English. In addition to extending this evidence base by comparing reading acquisition in English with the more transparent German, we conducted a longitudinal study and investigated whether different early reading skills made different contributions to word reading as a function of orthography. Children (n = 133) were recruited from the first year of primary school in New Zealand (age 5;8) and Germany (age 7;2) and from kindergartens in Germany (age 5;0) to provide both age- and schooling-matched samples. Parallel measures of phonemic awareness, vocabulary, decoding skill, and word reading (accuracy) were administered at two time points, 1 year apart. An advantage for orthography and school attendance existed for reading development. Vocabulary made a greater contribution to word reading in English than in German as did decoding skill. Findings underscore the relative importance of vocabulary and decoding skills for early reading in English.  相似文献

A growing number of studies now suggest that sensitivity to the rhythmic patterning of speech (prosody) is implicated in successful reading acquisition. However, recent evidence suggests that prosody is not a unitary construct and that the different components of prosody (stress, intonation, and timing) operating at different linguistic levels (word, phrase, and sentence) may be related to reading development in different ways. Sixty-two five- to seven-year-old English-speaking children completed a newly developed, multi-component measure designed to assess several different aspects of prosodic sensitivity in a single, easily-administered task. The new measure was found to be sensitive to individual differences in prosodic sensitivity and participants’ overall scores were significantly correlated with measures of vocabulary, phonological awareness, phonological decoding, text reading accuracy, and reading comprehension. An exploratory factor analysis suggested that the multi-component measure of prosodic sensitivity distinguished between the processing of stress, intonation, and timing. The task also distinguished between word-level and sentence-level sensitivity to stress information. These findings add to the growing literature demonstrating a relationship between prosodic sensitivity and reading and represent a first step towards disentangling prosody and developing a more sophisticated understanding of its role in early reading development.  相似文献

We evaluated neuro‐functional changes associated with late acquisition of reading in an illiterate adult who underwent 20 longitudinal functional magnetic resonance imaging (fMRI) scans during 2 years, while the participant progressed from complete illiteracy to a modest level of alphabetical decoding. Initially, the participant did not activate neural circuits for reading when he was exposed to words; gradually, however, he began to present activation in left occipitotemporal cortex, at the visual word form area. This increase was accompanied by a decrease in face responses. Reading‐related responses also emerged in language‐related areas of the inferior frontal gyrus and temporal lobe. Additional activations in superior parietal lobe, superior frontal gyrus and posterior medial frontal cortex suggested that reading remained dependent on effortful executive attention and working memory processes. Nevertheless, the results indicate that adult plasticity can be sufficient to induce rapid changes in brain responses to written words and faces in an unschooled and illiterate adult.  相似文献

Authors examined the relationship between individual differences in L1 print exposure and differences in early L1 skills and later L2 aptitude, L2 proficiency, and L2 classroom achievement. Participants were administered measures of L1 word decoding, spelling, phonemic awareness, reading comprehension, receptive vocabulary, and listening comprehension in 1?C5th grades, and then followed into 9?C10th grades where measures of L2 aptitude, L2 proficiency, and L1 print exposure were administered. Students?? responses on the L1 print exposure measure were used to divide them into High, Average, and Low Print groups. Findings showed significant differences between the High versus Low Print groups on all L1 skill measures, L2 aptitude and L2 proficiency tests, and L2 classroom achievement after controlling for IQ. L1 skill differences between the groups emerged as early as 1st grade. L1 phonemic awareness, L1 word decoding, and L1 spelling measures were the best discriminators of L1 print exposure among the three groups. Results suggest that early success in L1 reading and reading volume prior to L2 study may be related to differences in L2 aptitude, L2 proficiency, and L2 achievement several years later.  相似文献

The ultimate goal of children's reading development is the full and fluid understanding of texts. Morphological structure awareness, or children's awareness of the minimal units of meaning in language, has been identified as a key skill influencing reading comprehension. Here, we evaluate the roles of morphological structure awareness and two related skills, morphological analysis and morphological decoding, in Grade 3 and Grade 5 children's reading comprehension. Respectively, morphological decoding and analysis refer to the use of morphemes in reading and in understanding words. Critically, our analyses show that, together, morphological structure awareness, morphological decoding and morphological analysis account for 8% of the variance in reading comprehension, after controlling for children's age, phonological awareness, nonverbal reasoning and word reading skill. Further, of these dimensions, each of morphological decoding and morphological analysis makes a unique contribution to reading comprehension. We discuss these findings in terms of current theories of reading development and educational curricula.  相似文献
