This study investigates the role of linguistic and visuospatial attentional processes in predicting reading fluency in typical Italian readers attending primary school. Tasks were administered to 651 children with reading fluency z scores > ?1.5 standard deviation to evaluate their phonological awareness, rapid automatized naming (RAN), verbal short-term memory, vocabulary, visual search skills, verbal-visual recall, and visual-spatial attention. Hybrid models combining confirmatory factor analysis and path analysis were used to evaluate the data obtained from younger (first and second grade) and older (third–fifth grade) children, respectively. The results showed that phonological awareness and RAN played a significant role among younger children, while also vocabulary, verbal short-term memory, and visuospatial attention were significant factors among older children.  相似文献

The ability of working memory skills (measured by tasks assessing all four working memory components), IQ, language, phonological awareness, literacy, rapid naming, and speed of processing at 6 years of age, before reading was taught, to predict reading abilities (decoding, reading comprehension, and reading time) a year later was examined in 97 children. Among all working memory components, phonological complex memory contributed most to predicting all three reading abilities. A capacity measure of phonological complex memory, based on passing a minimum threshold in those tasks, contributed to the explained variance of decoding and reading comprehension. Findings suggest that a minimal ability of phonological complex memory is necessary for children to attain a normal reading level. Adding assessment of phonological complex memory, before formal teaching of reading begins, to more common measures might better estimate children’s likelihood of future academic success.  相似文献

The general magnocellular theory postulates that dyslexia is the consequence of a multimodal deficit in the processing of transient and dynamic stimuli. In the auditory modality, this deficit has been hypothesized to interfere with accurate speech perception, and subsequently disrupt the development of phonological and later reading and spelling skills. In the visual modality, an analogous problem might interfere with literacy development by affecting orthographic skills. In this prospective longitudinal study, we tested dynamic auditory and visual processing, speech-in-noise perception, phonological ability and orthographic ability in 62 five-year-old preschool children. Predictive relations towards first grade reading and spelling measures were explored and the validity of the global magnocellular model was evaluated using causal path analysis. In particular, we demonstrated that dynamic auditory processing was related to speech perception, which itself was related to phonological awareness. Similarly, dynamic visual processing was related to orthographic ability. Subsequently, phonological awareness, orthographic ability and verbal short-term memory were unique predictors of reading and spelling development.  相似文献

通过对儿童阅读发展这一领域相关研究的回顾,对汉语儿童阅读能力发展中的语音加工问题进行了探讨。在汉语阅读过程中,语音成分的介入已经得到了研究的普遍支持,但是在语音技能与阅读能力间的关系方面,虽然语音加工技能的不同成分(语音意识、声旁意识及言语工作记忆)与儿童阅读能力发展间都存在着一定的联系,但这些语音技能在汉语儿童阅读能力发展中所起作用的具体机制及介入程度还需进一步的研究论证。  相似文献

本研究对汉语阅读障碍的加工缺陷进行探讨,期望有助于揭示语言加工的普遍性与特殊性,以及阅读障碍的成因,并可为后期的干预提供帮助。研究采用改编的言语认知测验对阅读水平匹配组与阅读障碍组和生理年龄匹配组进行比较后发现,阅读障碍组在语音意识和正字法加工任务上的成绩均明显差于生理年龄控制组和阅读水平匹配组;阅读障碍组在快速命名和语音记忆任务上的成绩不如生理年龄匹配组,仅达到阅读水平匹配组水平。因此,汉语发展性阅读障碍儿童存在语音意识和正字法加工缺陷,这两种缺陷可能是阅读障碍儿童面临的最主要的两大缺陷;阅读障碍儿童在快速命名和语音记忆上的不足可能是发展迟滞所致。同时,大多数的汉语阅读障碍儿童存在不止一种的认知缺陷。阅读障碍儿童在语音意识和正字法加工上存在缺陷的比例最高。  相似文献

This study investigates whether working memory skills of children are related to teacher ratings of their progress towards learning goals at the time of school entry, at 4 or 5 years of age. A sample of 194 children was tested on measures of working memory, phonological awareness, and non‐verbal ability, in addition to the school‐based baseline assessments in the areas of reading, writing, mathematics, speaking and listening, and personal and social development. Various aspects of cognitive functioning formed unique associations with baseline assessments; for example complex memory span with rated writing skills, phonological short‐term memory with both reading and speaking and listening skills, and sentence repetition scores with both mathematics and personal and social skills. Rated reading skills were also uniquely associated with phonological awareness scores. The findings indicate that the capacity to store and process material over short periods of time, referred to as working memory, and also the awareness of phonological structure, may play a crucial role in key learning areas for children at the beginning of formal education.  相似文献

Working memory in children with reading disabilities   总被引:4,自引:0,他引:4  
This study investigated associations between working memory (measured by complex memory tasks) and both reading and mathematics abilities, as well as the possible mediating factors of fluid intelligence, verbal abilities, short-term memory (STM), and phonological awareness, in a sample of 46 6- to 11-year-olds with reading disabilities. As a whole, the sample was characterized by deficits in complex memory and visuospatial STM and by low IQ scores; language, phonological STM, and phonological awareness abilities fell in the low average range. Severity of reading difficulties within the sample was significantly associated with complex memory, language, and phonological awareness abilities, whereas poor mathematics abilities were linked with complex memory, phonological STM, and phonological awareness scores. These findings suggest that working memory skills indexed by complex memory tasks represent an important constraint on the acquisition of skill and knowledge in reading and mathematics. Possible mechanisms for the contribution of working memory to learning, and the implications for educational practice, are considered.  相似文献

While there is evidence for an association between the development of reading and arithmetic, the precise locus of this relationship remains to be determined. Findings from cognitive neuroscience research that point to shared neural correlates for phonological processing and arithmetic as well as recent behavioral evidence led to the present hypothesis that there exists a highly specific association between phonological awareness and single‐digit arithmetic with relatively small problem sizes. The present study examined this association in 37 typically developing fourth and fifth grade children. Regression analyses revealed that phonological awareness was specifically and uniquely related to arithmetic problems with a small but not large problem size. Further analysis indicated that problems with a high probability of being solved by retrieval, but not those typically associated with procedural problem‐solving strategies, are correlated with phonological awareness. The specific association between phonological awareness and arithmetic problems with a small problem size and those for which a retrieval strategy is most common was maintained even after controlling for general reading ability and phonological short‐term memory. The present findings indicate that the quality of children’s long‐term phonological representations mediates individual differences in single‐digit arithmetic, suggesting that more distinct long‐term phonological representations are related to more efficient arithmetic fact retrieval.  相似文献

The development of reading ability in a group of deaf children was followed over a 3-year period. A total of 29 deaf children (7-8 years of age at the first assessment) participated in the study, and every 12 months they were given a battery of literacy, cognitive, and language tasks. Earlier vocabulary and speechreading skills predicted longitudinal growth in reading achievement. The relations between reading and the predictor variables showed developmental change. Earlier reading ability was related to later phonological awareness skills, suggesting that deaf children might develop their phonological awareness through reading. Deaf children who had the most age-appropriate reading skills tended to have less severe hearing losses and earlier diagnoses and also preferred to communicate through speech. The theoretical implications of the role for speechreading, vocabulary and phonological awareness in deaf children’s literacy are discussed.  相似文献

This study examines the relationships between phonological awareness, visual-spatial sketchpad (VSSP) functioning and arithmetic attainment in young children. A sample of 42 children had their VSSP functioning and phonological awareness assessed when they were 5 years old. Approximately 12 months later their nonverbal reasoning, vocabulary, arithmetic, and reading attainment were assessed. Together, VSSP functioning, phonological awareness, vocabulary, and nonverbal reasoning predicted 41% of the variation in the children's arithmetic attainment. Only phonological awareness and VSSP functioning were significant independent predictors. In contrast, only phonological awareness was a significant independent predictor of reading attainment. These findings are consistent with phonological awareness influencing both the development of reading and arithmetic, whilst VSSP functioning only impacts on arithmetic development.  相似文献

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.

This study tested the segmentation hypothesis of dyslexia by measuring implicit phonological representations in reading-disabled 11- to 13-year-olds. Implicit measures included lexical gating, priming, and syllable similarity tasks designed to reduce metalinguistic demands. Children with dyslexia performed consistently worse than CA and RA controls when more segmental representations were required across all three tasks. Implicit phonological representations were correlated with measures of speech perception, phoneme awareness, and phonological short-term memory, but not rapid automatized naming, and accounted for unique variance in predicting reading ability. Results provide strong support for less mature implicit phonological representations in children with dyslexia.  相似文献

We examined the relations among phonological awareness, music perception skills, and early reading skills in a population of 100 4- and 5-year-old children. Music skills were found to correlate significantly with both phonological awareness and reading development. Regression analyses indicated that music perception skills contributed unique variance in predicting reading ability, even when variance due to phonological awareness and other cognitive abilities (math, digit span, and vocabulary) had been accounted for. Thus, music perception appears to tap auditory mechanisms related to reading that only partially overlap with those related to phonological awareness, suggesting that both linguistic and nonlinguistic general auditory mechanisms are involved in reading.  相似文献

Word decoding ability is a critical factor in reading performance. In the present study, we examined the relationship between word decoding ability and three different phonological skills; phonemic awareness, verbal short-term memory (V-STM), and rapid automatic naming (RAN) in 1007 Scandinavian third- and fifth-graders. In the first part of the study, we sought to investigate the influence of the three phonological skills on word decoding ability. Using multiple regression analysis, our result clearly demonstrated that phonemic awareness was the most powerful phonological skill explaining variance in word decoding ability among average decoders. Among children with poor decoding skills, however, RAN was the most important factor in Grade 3, whereas V-STM was the main contributor to decoding ability among children in Grade 5. In the second part of the research, we examined the relationship between poor phonological skills and word decoding ability. Interestingly, our result revealed that approximately one half of the children with phonological difficulties, still performed within the average range with regard to word decoding ability. However, our analyses confirmed earlier research concerning the severe word decoding difficulties children with both poor phonemic awareness and restricted V-STM, experience.  相似文献

The purpose of this study was to investigate the power of early measures of phonological skills (phonemic awareness, rapid naming, short-term memory) in predicting later reading skills at various points of time. About 70 children were followed from the end of kindergarten to the middle of grade 2. Correlation analyses were performed as well as a linear growth curve analyses. In the traditional regression analysis, phonemic awareness in kindergarten explained about 27% of the variance in word reading six months later and about 9.5% of the variance at the end of grade 1. Even when prior level of reading skill was included in the predictive equation, a significant amount of variance was still explained by phonemic awareness. The other predictor variables did not explain any variance in word reading, and phonemic awareness did not predict any variance in reading skills in grade 2. When using sentence reading as the dependent variable, phonemic awareness explained about 16% of unique variance after six months, and about 13% of the variance in the middle of grade 2. Similarly, when employing growth curve analysis, phonemic awareness was the only phonological factor that accounted for significant variance in the word reading slope, explaining about 25% of its variance, whereas naming and short-term memory did not explain any unique variance. The lack of predictive power of phonemic awareness on the sentence b-slope is assumed to be caused by unreliable sentence scores in kindergarten.  相似文献
