The present 4-year longitudinal study examined preschool predictors of Grade 1 dyslexia status in a Chinese population in Hong Kong where children started learning to read at the age of three. Seventy-five and 39 Chinese children with high and low familial risk respectively were tested on Chinese word reading, oral language skills, morphological awareness, phonological skills, rapid naming, and print-related skills from age 4 to 6 and a standardized dyslexia test at age 7. Results showed that children of the high risk group performed significantly worse than the low risk group in Chinese literacy, phonological awareness, and orthographic skills at age 7. All the children with dyslexia had word reading difficulties in at least one preschool year. Results of the logistic regression showed that preschool verbal production, syllable deletion, and letter naming were the best predictors of dyslexia outcome at age 7. As in alphabetic languages, preschool oral language skills like verbal production, phonological skills, and print-related skills are the most significant predictors of children’s later reading difficulties. 相似文献

Emerging phonological awareness was compared in two groups of 3.5-year-old children belonging to the Jyv?skyl? Longitudinal Study of Dyslexia (JLD): children with familial risk of dyslexia (at-risk group n = 98) and children without such risk (control group n = 91). Four computer animated tasks were used: Word-level and Syllable-level Segment Identification, Synthesis, and Continuation of Phonological Units. The control group children manifested higher mastery than children in the at-risk group in phonological awareness, and the proportion of children with a low phonological awareness mean score was 2.5 times higher in the at-risk group than in the control group. In both groups, phonological awareness at 3.5 years was predicted by early language skills assessed between 14 and 26 months of age, and it was also associated with concurrent language. The difference between the at-risk and control group at 3.5-year in phonological awareness remained significant, even when the effect of other language skills such as productive and receptive vocabulary, and mastery of inflections, measured both at earlier ages and concurrently were controlled for. Our findings indicate that familial risk for dyslexia is reliably reflected in emerging phonological awareness already at this early age and it can be assessed independently of other language skills. 相似文献

In a 3‐year longitudinal study, we examined the relationships between oral language development, early training and reading acquisition on word‐identification and reading‐comprehension tests administered to a sample of 687 French children. Hierarchical linear models showed that both phonological awareness and oral comprehension at the age of 4 years were relevant to reading acquisition 2 years later. These two broad skills explained separate parts of the variance on both outcome measures, while revealing opposite effects: phonological skills explained more variance for alphabetic reading skills and oral comprehension explained more variance for reading comprehension. We also assessed the effects of two preschool training programmes focusing on either phonological awareness or comprehension skills. The results showed that phonological awareness training had a positive effect on alphabetic scores, and comprehension training had a positive effect on reading comprehension. These results provide insight into early oral instruction and contribute to the theoretical debate about the linguistic predictors of literacy acquisition. 相似文献

Learning to read in a shallow alphabetic orthography such as Urdu may depend primarily on phonological processing skills, whilst learning to read in a deeper orthography, such as English, may place more reliance on visual processing skills. This study explores the effects of Urdu on the acquisition of English literacy skills by comparing the reading, memory and phonological processing skills of bilingual Urdu‐English and monolingual English children (7–8 years). The bilingual children had more difficulty in reading irregular English words, but were better at reading regular words and nonwords compared to the monolinguals. The poor performance of the bilingual children with irregular English words was linked to their poor visual memory skills, whilst their good performance with regular words and nonwords was related to the presence of enhanced phonological skills. The results demonstrate the transfer of first language skills to reading development in a second language. In English, first language skills can facilitate the development of either lexical or non‐lexical routes to reading. 相似文献

It is not known whether children who are struggling with reading in a non‐dominant language will respond better to a phonological intervention or to one that addresses oral proficiency. Multilingual seven‐to nine‐year‐olds showing reading difficulty in a non‐dominant language, English, were given a three‐week intervention in phonological skills or in language proficiency and were compared with two control groups (one with reading difficulties and one with no reading difficulties) who received a non‐language based intervention. The group receiving the explicit phonological instructions showed significantly better gain in reading and spelling measures than the language proficiency and reading difficulties control group, but did not reach the levels of the noreading‐difficulty group. The phonological intervention was particularly effective for children with the lowest single‐word reading scores. We suggest that the intervention helped to catalyse the fine‐tuning of the phonological domain, making phonological representations optimally available for decoding, phonological manipulations and literacy development. 相似文献

This paper focused on the assessment of phonological skills amongst children with developmental dyslexia. Findings from assessments of English and Hungarian monolingual children with and without literacy deficits and bilingual Filipino children with and without literacy deficits in English indicated that performance on phonological‐based tasks often used in dyslexia assessment batteries was influenced by the language background. Monolingual English children with poor literacy skills showed characteristic deficits in most areas of phonological ability, whereas Hungarian counterparts showed little evidence of such difficulties. Bilingual Filipino children with poor English literacy skills showed equivalent profiles to their monolingual counterparts only when assessments in both English and Filipino were considered. The paper discusses difficulties of generalising assessment procedures from one language context to another. 相似文献

Participants were administered multiple measures of phonological awareness, oral language, and rapid automatized naming at the beginning of kindergarten and multiple measures of word reading at the end of second grade. A structural equation model was fit to the data and latent scores were used to identify children with a deficit in phonological awareness alone or in combination with other kindergarten deficits. Children with a deficit in phonological awareness in kindergarten were found to be five times more likely to have dyslexia in second grade than children without such a deficit. This risk ratio substantially increased with the addition of deficits in both oral language and rapid naming. Whereas children with one or more kindergarten deficits were at heighten risk for dyslexia, some of these children were found to be adequate or better readers. These results are discussed within a multifactorial model of dyslexia that includes both risk and protective factors. 相似文献

This study investigated the relationships between phonological awareness and reading in Oriya and English. Oriya is the official language of Orissa, an eastern state of India. The writing system is an alphasyllabary. Ninety‐nine fifth grade children (mean age 9 years 7 months) were assessed on measures of phonological awareness, word reading and pseudo‐word reading in both languages. Forty‐eight of the children attended Oriya‐medium schools where they received literacy instruction in Oriya from grade 1 and learned English from grade 2. Fifty‐one children attended English‐medium schools where they received literacy instruction in English from grade 1 and in Oriya from grade 2. The results showed that phonological awareness in Oriya contributed significantly to reading Oriya and English words and pseudo‐words for the children in the Oriya‐medium schools. However, it only contributed to Oriya pseudo‐word reading and English word reading for children in the English‐medium schools. Phonological awareness in English contributed to English word and pseudo‐word reading for both groups. Further analyses investigated the contribution of awareness of large phonological units (syllable, onsets and rimes) and small phonological units (phonemes) to reading in each language. The data suggest that cross‐language transfer and facilitation of phonological awareness to word reading is not symmetrical across languages and may depend both on the characteristics of the different orthographies of the languages being learned and whether the first literacy language is also the first spoken language. 相似文献

Family risk of dyslexia is continuous: individual differences in the precursors of reading skill 总被引：12，自引：0，他引：12
The development of 56 children at family risk of dyslexia was followed from the age of 3 years, 9 months to 8 years. In the high-risk group, 66% had reading disabilities at age 8 years compared with 13% in a control group from similar, middle-class backgrounds. However, the family risk of dyslexia was continuous, and high-risk children who did not fulfil criteria for reading impairment at 8 years performed as poorly at age 6 as did high-risk impaired children on tests of grapheme-phoneme knowledge. The findings are interpreted within an interactive model of reading development in which problems in establishing a phonological pathway in dyslexic families may be compensated early by children who have strong language skills. 相似文献

The study investigated cognitive deficits associated with dyslexia and familial risk of dyslexia (endophenotypes) by comparing children from families with and without a history of dyslexia. Eighty-eight school-aged children were assessed on measures of phonology, language and rapid automatized naming. A series of regression analyses with family risk and dyslexia status as predictors indicated that word recall, morphology, and rapid automatized naming were associated with the deficit, whereas the two phonological measures (phoneme awareness and nonword repetition) were associated with both literacy deficits and family risk, suggesting that the phonological deficit is an endophenotype of dyslexia. Whereas the association with familial risk was similar for the two phonological measures, they differed in their relation to dyslexia status: Phoneme awareness showed a stronger association with dyslexia than risk status, whereas nonword repetition was more strongly related to the risk. The data are interpreted within the framework of multiple deficit models of dyslexia. 相似文献

The present study evaluated the idea that the hemisphere-specific cognitive demands of reading and writing may induce task-specific maladaptive patterns of language lateralization in children with dyslexia. Situation-specific lateralization was examined in a repeated measures design under three dichotic listening conditions: baseline, concurrent reading, and concurrent writing. Twelve males with phonological dyslexia, 8 to 12 years old, were compared to 12 age-matched and 12 younger reading-matched good readers. Lateralization patterns were examined for condition-specific relationships to pseudoword decoding, word recognition, reading comprehension, spelling, and arithmetic. The results show that dyslexia is not related to incomplete lateralization or to a failure to inhibit verbal processing in the right hemisphere during reading and writing. Reading increased the lateralization of the children with dyslexia, which had a negative relation to arithmetic; writing caused a decrease in lateralization, which was linked specifically to deficits in phonological decoding and visual word recognition. The results suggest that children with dyslexia suffer from a selective linguistic vulnerability to left-hemisphere interference from the idiosyncratic attentional and processing demands of particular school tasks. Dyslexia is a much more dynamic and environmentally sensitive disorder than previously thought. 相似文献

A follow‐up study was conducted on AS, previously reported as an English‐Japanese bilingual with monolingual phonological dyslexia in English ( Wydell and Butterworth, 1999 ). It was hypothesised that AS's fundamental deficit which lead to his dyslexia in English would still persist despite him successfully taking a BSc course in an English‐speaking country. AS and his Japanese and English control participants were asked to read aloud a target stimulus first, and then to decide whether the target was a word or nonword. Unlike the control participants, AS showed a marked dissociation between his performance in the lexical (orthographic and phonological) decision and the word naming tasks. Often those words and pseudo‐homophones (e.g. neym), which AS read erroneously, were correct in the decision tasks – the target pseudo‐homophone or word was substituted by another orthographically similar word. The results thus demonstrated that his reading of unfamiliar words or nonwords is essentially based on orthographic approximation using the visual similarities between words. The results confirmed the earlier finding that AS has a core phonological deficit which led to his dyslexia but never affected his reading in Japanese. The results also confirmed that this deficit persists when reading in English. This implies that whatever the neurological abnormality that AS may have, this only affects certain languages, and this abnormality persists with time. 相似文献

Children at risk for familial dyslexia (n = 107) and their controls (n = 93) have been followed from birth to school entry in the Jyvaskyla Longitudinal study of Dyslexia (JLD) on developmental factors linked to reading and dyslexia. At the point of school entry, the majority of the at-risk children displayed decoding ability that fell at least 1 SD below the mean of the control group. Measures of speech processing were the earliest indices to show both group differences in infancy and also significant predictive associations with reading acquisition. A number of measures of language, including phonological and morphological skill collected repeatedly from age three, revealed group differences and predictive correlations. Both the group differences and the predictive associations to later language and reading ability strengthened as a function of increasing age. The predictions, however, tend to be stronger and the spectrum of significant correlations wider in the at-risk group. These results are crucial to early identification and intervention of dyslexia in at-risk children. 相似文献

Previous U.K. population‐based studies have found associations amongst early speech and language difficulties, socioeconomic disadvantage and children's word‐reading ability later on. We examine the strength of these associations in a recent U.K. population‐based birth cohort. Analyses were based on 13,680 participants. Linear regression models were fitted to identify factors that were associated with word‐reading score at the age of 7 years. Path analysis models were fitted to examine phonological skills as a mediator of the relationships. We found that male gender, preterm birth, naming vocabulary at age five, concerns about speech and language, maternal education, type of housing tenure, lone parenting, parent attachment and frequency of reading to the child were all independently associated with word reading. For each of these predictors, there was evidence suggesting that a substantial proportion of the effect may be mediated by phonological skills (ranging from 52 to 89%). Despite policy intervention, many of the same risk factors identified in previous studies still predict children's word‐reading ability in the United Kingdom. Results support the phonological model, with phonological skills on the pathway to word reading.
What is already known about this topic?
- A range of studies has implicated poor socioeconomic background and disadvantaged family circumstances as risks for children's poor word reading.
- Good early development of language skills is firmly established as a pathway to promoting reading ability.
- Not all poor readers show deficits in phonological skills, although such deficits correlate highly with reading difficulties.
What this paper adds
- This is an original analysis of factors in a recent cohort of U.K. children, using stratified sampling to be representative of the U.K. population as a whole.
- A range of child‐specific, family socioeconomic and family relationship factors were independently associated with word‐reading ability when children were age seven.
- For each of the predictors, there was evidence suggesting that a substantial proportion of the effect, if causal, may be mediated by phonological skills (ranging from 52 to 89%).
Implications for theory, policy or practice
- Despite policy intervention, many of the same risk factors identified in older studies still predict children's word‐reading ability in the United Kingdom.
- Results lend weight to the phonological model, where deficits in phonological skills are on the pathway to word reading.

The present study used the tip-of-the-tongue (TOT) experimental paradigm in a picture naming task to explore the source of the naming deficits of children with dyslexia. Compared with a control group of typically developing readers, the children with dyslexia showed fewer correct responses and spontaneous recalls, more don't know (DK) and TOT responses, and less accurate feeling of knowing (FOK) judgments. When they failed to retrieve a target word, the children with dyslexia did not differ from the control group in the partial semantic information they provided, but they gave less valid and more invalid partial phonological information. The children with dyslexia also benefited less from phonological cues. The phonologically related responses of the children with dyslexia elicited during the administration of the TOT procedure were related to their performance on a phonological awareness test. These findings suggest that the naming problems of children with dyslexia arise because of their difficulty in accessing the phonological word forms after the corresponding abstract lexical representation has been successfully accessed. The results are discussed in relation to the claim that two-stage models of naming can be profitably used in the early identification and treatment of reading disabilities. 相似文献

This study investigated the effects of three instructional conditions on precursors to successful reading for Spanish‐speaking English language learners (ELL). The study was conducted using a randomized, alternate treatment control group design specifically targeting phonological awareness (PA) listening comprehension (LC), and decoding in a sample of ELL (N= 82) including students who were and were not at risk for later reading failure. Two randomly assigned experimental intervention groups and one treatment control group were created to test the effectiveness of three instructional interventions that differed in the relative amount of time used for instructing the word‐ and text‐level targeted skills. Specifically, the two experimental intervention groups received different doses of LC relative to PA instruction, creating a LC Concentration group and a PA Concentration group. The treatment control group received only PA and alphabet knowledge instruction (word‐level skills). Results indicated that both at‐risk and not‐at‐risk ELLs in the LC Concentration group outperformed students in the other groups on almost all measures, including PA skills, despite minimal amounts of instructional time‐targeting word‐level skills. These data extend the existing literature by lending empirical support to the use of a LC component in early reading interventions for young ELL. 相似文献

This study evaluated the effect of sound-symbol association training on visual and phonological memory in children with a history of dyslexia. Pretests of phonological and visual memory, a sound-symbol training procedure, and phonological and visual memory posttests were administered to children with dyslexia, to children whose dyslexia had been compensated through remedial training, and to age- and reading level-matched comparison groups. Deficits in visual and phonological memory and memory for sound-symbol associations were demonstrated in the dyslexia group. For children with dyslexia and children whose dyslexia had been remediated, the sound-symbol training scores were significantly associated with word and pseudoword reading scores and were significantly lower than those of the comparison groups. Children with dyslexia and children whose dyslexia had been compensated showed significantly less facilitation of phonological memory following the training than did typical readers. Skilled readers showed some reduction in accuracy of visual memory following the training, which may be the result of interference of verbalization with a predominantly visual task. A parallel decrease was not observed in the children with dyslexia, possibly because these children did not use the verbal cues. Children with dyslexia and children whose dyslexia had been compensated seemed to have difficulty encoding the novel sounds in memory. As a result, they derived less phonological memory advantage and less visual memory interference from the training than did typical readers. Children in the compensated dyslexia group scored lower on sound-symbol training than their age peers. In other respects, the scores of these children were equivalent to those of the typically reading comparison groups. Children in the compensated dyslexia group exhibited higher phonological rehearsal, iconic memory, and associative memory scores than children in the dyslexia group. Implications for the remediation of dyslexia are discussed. 相似文献

Informed by knowledge of linguistics, research findings in the areas of monolingual and bilingual acquisition, dyslexia and speech therapy clinical practice, five factors are proposed to argue that the acquisition of English by young non‐native learners can be enhanced by learning activities which take into account factors of developmental sequence in language acquisition, language‐specific properties, the relationship between oral and written language, the what‐to‐learn‐first issue and the quality of the language input. Proper language goals can be set and appropriate activities designed, only if the language input provider interacts with a learner in a concrete activity while being sensitive to the developmental trajectory of monolingual speaking children, the development of the less dominant language in a bilingual child, the prosodic and phonological differences between the learner's mother tongue and the target language, the importance of phonological awareness which defines dyslexia, the use of non‐abstract language structures grounded in concrete lexical items in the early stage of language acquisition and the strategy of expanding learners' utterance by one element as used in speech therapy. 相似文献

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia. 相似文献

Multisyllabic words have been neglected in determining the relationship between spelling and sound in reading development. In a preliminary exploration of this topic, sensitivity to the phonological and orthographic composition of multisyllabic words and nonwords is examined amongst a group of English‐speaking 11‐year‐olds. The nature of the English language suggests that the syllable structure and stress pattern of words may influence the acquisition of higher‐order reading skills. A phonological awareness task confirms that syllable boundaries are ambiguous in certain English words. Furthermore, accuracy at reading multisyllabic words and nonwords appears sensitive to this ambiguity as a small advantage emerges for stimuli with more stable syllable structures. Nonword but not word reading is affected by syllable length, and nonwords are assigned stress patterns which appear to be related to the lexical syllables that were used to construct these items. These findings are related to current connectionist models of word recognition. 相似文献
