The present study reported data on phonological awareness, morphological awareness, and Chinese literacy skills of 294 children from an 8‐year longitudinal study. Results showed that mainland Chinese children's preliterate syllable awareness at ages 4 to 6 years uniquely predicted post‐literate morphological awareness at ages 7 to 10 years. Preliterate syllable awareness directly contributed to character reading and writing at age 11 years, while post‐literate phonemic awareness predicted only character reading at age 11 years. In addition, preliterate syllable and morphological awareness at ages 4 to 6 years had indirect effects on character reading and writing, reading fluency, and reading comprehension at age 11 years, through post‐literate morphological awareness at ages 7 to 10 years. Findings underscore the significant role of syllable awareness in Chinese character reading and writing, and the importance of morphological awareness in character‐level processing and high‐level literacy skills. More importantly, our results suggest the unique relation of syllable awareness and morphological awareness in Chinese as they focus on the same unit, which is also likely to map directly onto a character, the basic unit for high‐level Chinese reading skills.  相似文献

Recent research suggests an auditory temporal deficit as a possible contributing factor to poor phonemic awareness skills. This study investigated the relationship between auditory temporal processing of nonspeech sounds and phonological awareness ability in children with a reading disability, aged 8-12 years, using Tallal's tone-order judgement task. Normal performance on the tone-order task was established for 36 normal readers. Forty-two children with developmental reading disability were then subdivided by their performance on the tone-order task. Average and poor tone-order subgroups were then compared on their ability to process speech sounds and visual symbols, and on phonological awareness and reading. The presence of a tone-order deficit did not relate to performance on the order processing of speech sounds, to poorer phonological awareness or to more severe reading difficulties. In particular, there was no evidence of a group by interstimulus interval interaction, as previously described in the literature, and thus little support for a general auditory temporal processing difficulty as an underlying problem in poor readers. In this study, deficient order judgement on a nonverbal auditory temporal order task (tone task) did not underlie phonological awareness or reading difficulties.  相似文献

Recent efforts have focused on screening methods to identify children at risk for dyslexia as early as preschool/kindergarten. Unfortunately, while low sensitivity leads to under‐identification of at‐risk children, low specificity can lead to over‐identification, resulting in inaccurate allocation of limited educational resources. The present study focused on children identified as at‐risk in kindergarten who do not subsequently develop poor reading skills to specify factors associated with better reading outcomes among at‐risk children. Early screening was conducted in kindergarten and a subset of children was tracked longitudinally until second grade. Potential protective factors were evaluated at cognitive‐linguistic, environmental, and neural levels. Relative to at‐risk kindergarteners with subsequent poor reading, those with typical reading outcomes were characterized by significantly higher socioeconomic status (SES), speech production accuracy, and structural organization of the posterior right‐hemispheric superior longitudinal fasciculus (SLF). A positive association between structural organization of the right SLF and subsequent decoding skills was found to be specific to at‐risk children and not observed among typical controls. Among at‐risk children, several kindergarten‐age factors were found to significantly contribute to the prediction of subsequent decoding skills: white matter organization in the posterior right SLF, age, gender, SES, and phonological awareness. These findings suggest that putative compensatory mechanisms are already present by the start of kindergarten. The right SLF, in conjunction with the cognitive‐linguistic and socioeconomic factors identified, may play an important role in facilitating reading development among at‐risk children. This study has important implications for approaches to early screening, and assessment strategies for at‐risk children.  相似文献

Levels of phonological awareness in three cultures   总被引:12,自引:0,他引:12  
This study focused on syllable phoneme onset levels of phonological awareness in relation to reading of Chinese and English in kindergarten and first-grade children from Xian (China), Hong Kong, and Toronto, cultures that differ substantially in approaches to reading instruction. English syllable awareness among native Chinese speakers was as good as or better than that among English speakers, indicating that the Chinese language may promote syllable-level awareness in children. Hong Kong children recognized significantly more words in both English and Chinese but were significantly poorer than the Xian children in both syllable and phoneme onset deletion tasks, suggesting that Pinyin training (given in Xian only) may promote phonological awareness even at the syllable level. In both Xian and Hong Kong, measures of syllable awareness consistently predicted Chinese character recognition better than did phoneme onset awareness. In contrast, English word recognition was predicted differently by syllable and phoneme onset awareness across cultures. These results underscore the roles of both language and writing system in understanding levels of phonological awareness.  相似文献

Concept of word is a pivotal developmental insight that is reflected when preliterate learners are able to repeat a line of print and accurately point to the words while saying them (finger-point reading) and relocate a specific word within that line (word finding). Several studies have shown that letter knowledge, phonemic skills, one-to-one correspondence, and spelling relate to finger-point reading. However, no studies have examined the relationship between syllable awareness and finger-point reading despite the fact that finger-point reading requires learners to handle multisyllabic words. With a group of young children this study examined: (a) the influence of syllable-controlled text on learning finger-point reading and (b) the degree to which syllable awareness would contribute to the prediction of finger-point reading above letter naming and initial sound awareness. Syllable-controlled text did not influence finger-point reading but syllable awareness did predict a significant proportion of the variance in finger-point reading over and above letter knowledge and initial sound awareness. Implications of the interactive nature of phonological and print knowledge are discussed as well as capacity of young children to learn about print.  相似文献

This study tested if children with specific language impairment (SLI) or children with specific reading disability (SRD) have abnormal brain responses to sounds. We tested 6‐ to 12‐year‐old children with SLI (N =19), children with SRD (N =55), and age‐matched controls (N =36) for their passive auditory event‐related potentials (ERPs) to tones, rapid tones, vowels and consonant‐vowels. Thirty‐eight percent of the children with SLI or SRD had less typical passive auditory ERPs in the N1–P2 window to sounds in general, rather than to tones, rapid tones, vowels or consonant‐vowels specifically. The ERPs of these children were significantly ‘flatter’ in the N1–P2 region than normal. All the children with flatter ERPs in the N1–P2 region had poor non‐word reading. A subgroup of these poor non‐word readers also had poor non‐word repetition. These findings support the hypothesis that impaired auditory processing is a causal risk factor for both SLI and SRD.  相似文献

Dyslexia is heritable and associated with phonological processing deficits that can be reflected in the event‐related potentials (ERPs). Here, we recorded ERPs from 2‐month‐old infants at risk of dyslexia and from a control group to investigate whether their auditory system processes /bAk/ and /dAk/ changes differently. The speech sounds were presented in an oddball paradigm. The children were followed longitudinally and performed a word reading fluency test in second grade. The infant ERPs were subsequently analyzed according to high or low reading fluency in order to find a neurophysiological precursor of poor reading fluency. The results show that the fluent reading children (from both the at‐risk and the control group) processed the speech sound changes differentially in infancy as indicated by a mismatch response (MMR). In the control group the MMR was frontally positive and in the fluent at‐risk group the MMR was parietally positive. The non‐fluent at‐risk group did not show an MMR. We conclude that at‐risk children who became fluent readers were better at speech processing in infancy than those who became non‐fluent readers. This indicates a very early speech processing deficit in the group of later non‐fluent readers.  相似文献

The authors report a systematic meta-analytic review of the relationships among 3 of the most widely studied measures of children's phonological skills (phonemic awareness, rime awareness, and verbal short-term memory) and children's word reading skills. The review included both extreme group studies and correlational studies with unselected samples (235 studies were included, and 995 effect sizes were calculated). Results from extreme group comparisons indicated that children with dyslexia show a large deficit on phonemic awareness in relation to typically developing children of the same age (pooled effect size estimate: -1.37) and children matched on reading level (pooled effect size estimate: -0.57). There were significantly smaller group deficits on both rime awareness and verbal short-term memory (pooled effect size estimates: rime skills in relation to age-matched controls, -0.93, and reading-level controls, -0.37; verbal short-term memory skills in relation to age-matched controls, -0.71, and reading-level controls, -0.09). Analyses of studies of unselected samples showed that phonemic awareness was the strongest correlate of individual differences in word reading ability and that this effect remained reliable after controlling for variations in both verbal short-term memory and rime awareness. These findings support the pivotal role of phonemic awareness as a predictor of individual differences in reading development. We discuss whether such a relationship is a causal one and the implications of research in this area for current approaches to the teaching of reading and interventions for children with reading difficulties.  相似文献

Phonological awareness in young Chinese children   总被引:1,自引:0,他引:1  
Two studies explored the nature of phonological awareness (PA) in Chinese. In Study 1, involving 146 children, awareness of phoneme onset did not differ from chance levels at ages 3-5 years in preschool but increased to 70% correct in first grade, when children first received phonological coding (Pinyin) instruction. Similarly, tone awareness was at better than chance levels from second year kindergarten (age 4), but increased strongly and significantly in first grade to 74% accuracy. In contrast, syllable and rime awareness increased gradually and steadily across ages 3-6 years. Patterns suggest different influences of age and literacy instruction for different PA levels. In Study 2, involving 202 preschoolers, variance in Chinese character recognition was best explained by tasks of syllable awareness, tone awareness, and speeded naming. Findings underscore the unique importance of both tone and syllable for early character acquisition in Chinese children.  相似文献

This study examines the literacy outcomes for children from socially disadvantaged backgrounds who had received specific whole‐class phonological awareness (PA) and language intervention in preschool. The participants were 57 children who had been involved in the original intervention study. Their PA skills, letter‐sound knowledge, real word and non‐word spelling and reading comprehension were assessed in Grade 2. The results indicated that children who had received intervention in preschool performed similarly to the children who had not received intervention. The gains made in PA and language skills post intervention had failed to augment further literacy development. A post hoc examination of individual student profiles, however, revealed that a subgroup of children who had received intervention had maintained their enhanced performance and that the intervention cohort had similar scores on tests of PA ability to their age‐matched peers in the population. It was concluded that whole‐class, teacher‐delivered, PA and language intervention, while effective in the short term, does not lead to a generalized improvement in literacy skills in Grade 2. Possible reasons for the failure of the program to produce medium term gains are discussed.  相似文献

This study investigates whether orthographic consistency and transparency of languages have an impact on the development of reading strategies and reading sub‐skills (i.e. phonemic awareness and visual attention span) in bilingual children. We evaluated 21 French (opaque)‐Basque (transparent) bilingual children and 21 Spanish (transparent)‐Basque (transparent) bilingual children at Grade 2, and 16 additional children of each group at Grade 5. All of them were assessed in their common language (i.e. Basque) on tasks measuring word and pseudoword reading, phonemic awareness and visual attention span skills. The Spanish speaking groups showed better Basque pseudoword reading and better phonemic awareness abilities than their French speaking peers, but only in the most difficult conditions of the tasks. However, on the visual attention span task, the French‐Basque bilinguals showed the most efficient visual processing strategies to perform the task. Therefore, learning to read in an additional language affected differently Basque literacy skills, depending on whether this additional orthography was opaque (e.g. French) or transparent (e.g. Spanish). Moreover, we showed that the most noteworthy effects of Spanish and French orthographic transparency on Basque performance were related to the size of the phonological and visual grain used to perform the tasks.  相似文献

This 2-year study examined the effects of early second language exposure on phonological awareness skills. Syllable, onset-rime and phoneme awareness skills of 72 anglophone children attending English or French immersion programs in primary and grade 1 were investigated. Three-way mixed ANOVAS revealed the following effects and interactions. In terms of grade effect, grade 1 students performed significantly better than primary students on phoneme and onset-rime tasks. A stimulus language effect was observed for the three levels of phonological awareness. All children performed better on English tasks than on French ones. Interaction effects of stimulus language by program were revealed for phoneme as well as syllable tasks. Posthoc analyses revealed that French students performed better on English phoneme and syllable tasks than on French, while English students performed better than French immersion students on French syllable tasks. Correlational analyses revealed significant relationships between reading and phoneme and onset-rime phonological awareness tasks regardless of program of instruction (English, French immersion) or language of reading test (English, French). Syllable awareness was only significantly correlated with the French non-word reading task for the French immersion students.  相似文献

Long-term cognitive dynamics of fluent reading development   总被引:1,自引:0,他引:1  
Most theories of reading development assume a shift from slow sequential subword decoding to automatic processing of orthographic word forms. We hypothesized that this shift should be reflected in a concomitant shift in reading-related cognitive functions. The current study investigated the cognitive dynamics underlying reading development in a large school sample ranging from beginning to experienced readers. The results showed that phonological awareness (PA) and rapid automatized naming (RAN) contributed substantially to reading fluency over all six primary school grades. However, the relationship between PA and word (but not pseudoword) reading fluency decreased as a function of reading experience, whereas the relationship between RAN and word reading fluency increased gradually. Moreover, this cognitive shift was most pronounced for high-frequency words. The results seem to point to the development of one (and only one) reading network for all types of words in which processing load or type of processing depends on word familiarity and amount of reading experience.  相似文献

Children with reading difficulties and children with a history of repeated ear infections (Otitis Media, OM) are both thought to have phonological impairments, but for quite different reasons. This paper examines the profile of phonological and morphological awareness in poor readers and children with OM. Thirty‐three poor readers were compared to individually matched chronological age and reading age controls. Their phonological awareness and morphological awareness skills were consistently at the level of reading age matched controls. Unexpectedly, a significant minority (25%) of the poor readers had some degree of undiagnosed mild or very mild hearing loss. Twenty‐nine children with a history of OM and their matched controls completed the same battery of tasks. They showed relatively small delays in their literacy and showed no impairment in morphological awareness but had phonological awareness scores below the level of reading age matched controls. Further analysis suggested that this weakness in phonological awareness was carried by a specific weakness in segmenting and blending phonemes, with relatively good performance on phoneme manipulation tasks. Results suggest that children with OM show a circumscribed deficit in phoneme segmentation and blending, while poor readers show a broader metalinguistic impairment which is more closely associated with reading difficulties.  相似文献

Cortical function and related cognitive, language, and communication skills are genetically influenced. The auditory brainstem response to speech is linked to language skill, reading ability, cognitive skills, and speech‐in‐noise perception; however, the impact of shared genetic and environmental factors on the response has not been investigated. We assessed auditory brainstem responses to speech presented in quiet and background noise from (1) 23 pairs of same sex, same learning diagnosis siblings (Siblings), (2) 23 unrelated children matched on age, sex, IQ, and reading ability to one of the siblings (Reading‐Matched), and (3) 22 pairs of unrelated children matched on age and sex but not on reading ability to the same sibling (Age/Sex‐Matched). By quantifying response similarity as the intersubject response‐to‐response correlation for sibling pairs, reading‐matched pairs, and age‐ and sex‐matched pairs, we found that siblings had more similar responses than age‐ and sex‐matched pairs and reading‐matched pairs. Similarity of responses between siblings was as high as the similarity of responses collected from an individual over the course of the recording session. Responses from unrelated children matched on reading were more similar than responses from unrelated children matched only on age and sex, supporting previous data linking variations in auditory brainstem activity with variations in reading ability. These results suggest that auditory brainstem function can be influenced by siblingship and auditory‐based communication skills such as reading, motivating the use of speech‐evoked auditory brainstem responses for assessing risk of reading and communication impairments in family members.  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

Research suggests that early identification of developmental dyslexia is important for mitigating the negative effects of dyslexia, including reduced educational attainment and increased socioemotional difficulties. The strongest pre‐literacy predictors of dyslexia are rapid automatized naming (RAN), phonological awareness (PA), letter knowledge, and verbal short‐term memory. The relationship among these constructs has been debated, and several theories have emerged to explain the unique role of each in reading ability/disability. Furthermore, the stability of identification of risk based on these measures varies widely across studies, due in part to the different cut‐offs employed to designate risk. We applied a latent profile analysis technique with a diverse sample of 1215 kindergarten and pre‐kindergarten students from 20 schools, to investigate whether PA, RAN, letter knowledge, and verbal short‐term memory measures differentiated between homogenous profiles of performance on these measures. Six profiles of performance emerged from the data: average performers, below average performers, high performers, PA risk, RAN risk, and double‐deficit risk (both PA and RAN). A latent class regression model was employed to investigate the longitudinal stability of these groups in a representative subset of children (= 95) nearly two years later, at the end of 1st grade. Profile membership in the spring semester of pre‐kindergarten or fall semester of kindergarten was significantly predictive of later reading performance, with the specific patterns of performance on the different constructs remaining stable across the years. There was a higher frequency of PA and RAN deficits in children from lower socioeconomic status (SES) backgrounds. There was no evidence for the IQ–achievement discrepancy criterion traditionally used to diagnose dyslexia. Our results support the feasibility of early identification of dyslexia risk and point to the heterogeneity of risk profiles. These findings carry important implications for improving outcomes for children with dyslexia, based on more targeted interventions.  相似文献

Phoneme awareness is critical for literacy acquisition in English, but relatively little is known about the early development of phonological awareness in ESL (English as a second language) bilinguals when their two languages have different phonological structures. Using parallel tasks in English and Mandarin, we tracked the development of L1 (first language) and L2 (second language) syllable and phoneme awareness longitudinally in English-L1 and Mandarin-L1 prereaders (n=70, 4- and 5-year-olds) across three 6-month intervals. In English, the English-L1 children's performance was better in phoneme awareness at all three time points, but the Mandarin-L1 children's syllable awareness was equivalent to the English-L1 children's syllable awareness by Time 3. In Mandarin, the English-L1 children's phoneme awareness, but not their syllable awareness, was also significantly better than that of the Mandarin-L1 children at all three time points. Cross-lagged correlations revealed that only the English-L1 children applied their L1 syllable and phoneme awareness to their L2 (Mandarin) processing by Time 2 and that the Mandarin-L1 children seemed to require exposure to English (L2) before they developed phoneme awareness in either language. The data provide further evidence that phonological awareness is a language-general ability but that cross-language application depends on the similarity between the phonological structures of a child's L1 and L2. Implications for classroom teaching are briefly discussed.  相似文献

The objectives of the present study were twofold: (a) to explore the interrelationship among distal, proximal cognitive skills, and word reading; and (b) to identify those cognitive processes that predict phonological awareness and rapid naming. Seventy First-Nation Canadian children attending grades 3 and 4 were examined on phonological awareness, rapid naming, Word Identification, Word Attack, and the cognitive processing measures of planning, attention, successive, and simultaneous (PASS). Results indicated that phonological awareness and rapid naming uniquely predicted reading, whereas PASS variables did not, when the effects of phonological awareness and rapid naming were controlled. Finally, both phonological awareness and rapid naming were predicted by planning. Implications for diagnosis of children at risk for reading difficulties and remediation are discussed.  相似文献
