The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties.  相似文献

This study was an investigation of reading and spelling errors of dyslexic Arabic readers (n=20) compared with two groups of normal readers: a young readers group, matched with the dyslexics by reading level (n=20) and an age-matched group (n=20). They were tested on reading and spelling of texts, isolated words and pseudowords. Two research questions were the focus of this study: What are the reading and spelling profile errors of dyslexic native Arabic speakers? What is the effect of the Arabic orthography on these types of errors? The results of the reading error analysis revealed a clear contribution of the uniqueness of the Arabic orthography to the types of errors made by the three different groups. In addition, the error profiles of the dyslexic readers were similar to the error profiles made by the younger reading-level-matched group in percentages and in quality. The most prominent types of errors were morphological and semiphonetic, which highlighted the contribution of the Arabic orthography to these types of errors. Consistently, the profile of the spelling errors was similar in percentages and quality among the dyslexics and the reading-level-matched group but different from the age-matched group on the spelling measures. The analysis of the spelling errors revealed that the dominant type of error was mostly phonetic due to the limited orthographic lexicon. In addition, the Arabic orthography also contributed to these types of errors because many spelling mistakes were made due to poor knowledge of the spelling rules. The results of the reading and spelling errors are discussed from a reading development point of view. Further, two models are suggested, one for reading and one for spelling, to illustrate the cognitive processes that underlie the reading and spelling mistakes in this type of orthography.  相似文献

This article reports data from a training study of morphological awareness involving 33 dyslexic students in grades 4 - 5. The dyslexic students received 36 lessons of morphological awareness training each of about a quarter of an hour. The training was oral and focused on semantic aspects of morphemes. During the training period, the experimental group gained significantly more than a similar group of untrained controls (n = 27) on one of three measures of morphological awareness. Both groups, however, made equal gains on measures of phonological awareness, phoneme discimination and picture naming. The experimental group progressed significantly more than the controls in reading comprehension and in spelling of morphologically complex words. The results of the study suggest that it is possible to develop dyslexic students' morphological awareness. Furthermore, awareness of morphemes, the smallest meaningful units of language, may support the development of meaning - oriented decoding strategies in reading and spelling.  相似文献

The study investigates dyslexic and normal Hebrew readers’ perception of words containing a vowel letter in different orthographic and morphological contexts. In the first experiment, 72 undergraduate education students (half diagnosed with reading disabilities and half normal readers) were asked to judge pointed words with different morphological structures with and without the grapheme W. Half of the words had consistent (obligatory) W and half had inconsistent (optional) W. In the second experiment, the same procedure was repeated using the same words without pointing marks. Response latencies and accuracy were measured. In both experiments, dyslexic readers did less well than normal readers. They had lower scores on accurate lexical decisions and they took more time over these decisions. They also exhibited some deviant patterns, indicating that they cannot make use of orthographic and morphological cues that are available to normal readers, especially in the pointed experiment. Processing pointed words placed a heavier cognitive burden on the dyslexic readers. These findings are in line with other studies of adult dyslexic reader/writers, and support a reading / spelling processing model, which claims that internal orthographic representations of words are increasingly strengthened with each exposure during reading, but not all graphemes are strengthened equally. The general implication is that the ambiguities that exist in the relationships between orthography, phonology, and morphology underlie spelling knowledge, and are particularly difficult for dyslexic readers.  相似文献

Basic skills in reading and spelling and supporting metalinguistic abilities were assessed in ninth and tenth grade students in two school settings. Students attending a private high school for the learning disabled comprised one group and the other comprised low to middle range students from a public high school. Both the LD students and the regular high school students displayed deficiencies in spelling and in decoding, a factor in reading difficulty that is commonly supposed to dwindle in importance after the elementary school years. Treating the overlapping groups as a single sample, multiple regression analysis was used to investigate the contribution of nonword decoding skill and phonological and morphological awareness to spelling ability. The analysis revealed that decoding was the major component, predicting about half of the variance in spelling. The effect of phonological awareness was largely hidden by its high correlation with decoding, but was a significant predictor of spelling in its own right. Morphological awareness predicted spelling skill when the words to be spelled were morphologically complex. An additional study showed that differences in decoding and spelling ability were associated with differences in comprehension after controlling for reading experience and vocabulary. Even among experienced readers individual differences in comprehension of text reflect efficiency of phonological processing at the word level.  相似文献

This study was designed to examine the independent contribution of prosodic sensitivity—the rhythmic patterning of speech—to word reading and spelling in a sample of early readers. Ninety-three English-speaking children aged 5–6 years old (M = 69.28 months, SD = 3.67) were assessed for their prosodic sensitivity, vocabulary knowledge, phonological, and morphological awareness (predictor variables) along with their word reading and spelling (criterion variables). Bivariate (zero-order) correlation analyses revealed that prosodic sensitivity was significantly associated with all other variables in this study. Hierarchical regression analyses revealed that after controlling for individual differences in vocabulary, phonological, and morphological awareness, prosodic sensitivity was still able to explain unique variance in word reading, but was unable to make an independent contribution to spelling. The findings suggest that prosodic sensitivity gives added value to our understanding of children’s reading development.  相似文献

This study examined the contributions of vocabulary and spelling to the reading comprehension of students in grades 6–10 who were and were not classified as English language learners. Results indicate that vocabulary accounted for greater between-grade differences and unique variance (ΔR 2 = .11–.31) in comprehension as compared to spelling (ΔR 2 = .01–.09). However, the contribution of spelling to comprehension was higher in the upper grade levels included in this cross-sectional analysis and functioned as a mediator of the impact of vocabulary knowledge at all levels. The direct effect of vocabulary was strong but lower in magnitude at each successive grade level from .58 in grade 6 to .41 in grade 10 while the indirect effect through spelling increased in magnitude at each successive grade level from .09 in grade 6 to .16 in grade 10. There were no significant differences between the language groups in the magnitude of the indirect impact, suggesting both groups of students relied more on both sources of lexical information in higher grades as compared to students in lower grades.  相似文献

Two groups of adolescents with a childhood history of language impairment were compared with a group of developmentally dyslexic young people of the same age and nonverbal ability. The study also included two comparison groups of typically developing children, one of the same age as those in the clinical groups, and a younger comparison group of similar reading level to the dyslexic students. Tests of spoken and written language skills revealed that the adolescents with dyslexia were indistinguishable from those with resolved language impairments on spoken language tasks, and both groups performed at age-expected levels. However, both dyslexic readers and those with resolved specific language impairments showed deficits in phonological awareness. On written language tasks, a different pattern of performance was apparent. In reading and spelling, adolescents with dyslexia performed only as well as those with persistent oral language impairments and younger controls. However, their reading comprehension was better. The theoretical and educational implications of these findings are discussed.  相似文献

A phonological deficit constitutes a primary cause of developmental dyslexia, which persists into adulthood and can explain some aspects of their reading impairment. Nevertheless, some dyslexic adults successfully manage to study at university level, although very little is currently known about how they achieve this. The present study investigated at both the individual and group levels, whether the development of another oral language skill, namely, morphological knowledge, can be preserved and dissociated from the development of phonological knowledge. Reading, phonological, and morphological abilities were measured in 20 dyslexic and 20 non-dyslexic university students. The results confirmed the persistence of deficits in phonological but not morphological abilities, thereby revealing a dissociation in the development of these two skills. Moreover, the magnitude of the dissociation correlated with reading level. The outcome supports the claim that university students with dyslexia may compensate for phonological weaknesses by drawing on morphological knowledge in reading.  相似文献

We know that knowledge of word structure—morphology—relates to reading, but there is limited research on its unique contribution to reading comprehension, especially with students in middle and high schools and with the nesting of students within classrooms taken into account. In this study with 4780 students in grades 3 to 10, we examined how students' winter scores in morphological knowledge, spelling, text reading efficiency, and reading comprehension predicted spring scores in reading comprehension. Reading comprehension was measured by a computeradaptive, interim reading assessment. Bivariate relations were examined and a strong relation between morphological knowledge and reading comprehension was observed in all grades except grade 10. Multilevel analyses showed that morphological knowledge added 2%–9% unique variance beyond the autoregressor in predicting spring reading comprehension at the student level and that over 90% of the large variability between classrooms was explained by performance on these component skills. Educational implications were discussed.  相似文献

Morphological analysis of words has been shown to characterize skilled reading. A manipulation on the presentation of words, designed to encourage this process, was examined in dyslexic readers. Fifty-eight Hebrew-speaking university students with dyslexia were divided into three groups. One underwent a very short-term morpheme-based training, consisting of a time-restricted exposure to the root morphemes of words presented in a lexical decision task. The rest of the words’ letters remained on screen until a response. Another group received a control training consisting of the same procedure, except that the presentation of a nonmorphological orthographic unit was manipulated. Two untrained control groups, of dyslexic readers and of typical readers (n = 20), received pre- and posttest measures without training. The results suggest modest but positive effects on reading and spelling following the morpheme-based training, thereby suggesting that the morphological manipulation examined should be integrated in more intensive trainings.  相似文献

This study examined individual differences among beginning readers of English as a foreign language (EFL). The study concentrated on the effects of underlying first language (L1) knowledge as well as EFL letter and vocabulary knowledge. Phonological and morphological awareness, spelling, vocabulary knowledge, and word reading in Hebrew L1, in addition to knowledge of EFL letters and EFL vocabulary, were measured. The study also investigated the effect of socioeconomic background (SES) on beginning EFL readers. Participants included 145 fourth graders from three schools representing two socioeconomic backgrounds in the north of Israel. The results indicate that knowledge of English letters played a more prominent role than knowledge of Hebrew L1 components in differentiating between strong and weak EFL readers. The Linguistic Coding Differences Hypothesis was supported by L1 phonological awareness, word reading, and vocabulary knowledge appearing as part of discriminating functions. The presence of English vocabulary knowledge as part of the discriminant functions provides support for English word reading being more than just a decoding task for EFL beginner readers. Socioeconomic status differentiated the groups for EFL word recognition but not for EFL reading comprehension.  相似文献

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.  相似文献

This study investigated (1) the role of syllable awareness in word reading and spelling after accounting for the effects of print-related skills (letter-name and letter-sound knowledge, and rapid serial naming), and (2) unique contributions of orthographic, semantic (vocabulary and morphological awareness), phonological, and print-related predictors to word reading and spelling for 4- and 5-year old Korean-speaking children (N = 168). Syllable awareness was found to be positively related to word reading and spelling after accounting for print-related skills and phoneme awareness. Letter-name knowledge and orthographic awareness were uniquely related to word reading and spelling after accounting for other language and literacy-related skills. In addition, phoneme awareness was uniquely related to spelling whereas rapid serial naming was uniquely related to word reading, after accounting for other language and literacy-related skills. Semantic knowledge such as vocabulary and morphological awareness were not related to either word reading or spelling after accounting for other language and literacy-related skills. Word reading and spelling remained uniquely and positively related to each other. These findings are discussed in light of crosslinguistic variation in early literacy acquisition.  相似文献

This 1-year longitudinal study examined the extent to which morphological awareness, orthographic knowledge, and phonological awareness, along with speeded naming, uniquely explained word recognition, dictation (i.e., spelling), and reading comprehension among 171 young Hong Kong Chinese children. With age and vocabulary knowledge statistically controlled, both morphological awareness and orthographic knowledge were uniquely associated with all three concurrently measured literacy skills, as well as longitudinal measures of specific literacy skills. Naming speed was also uniquely associated with concurrent word reading, as well as all three literacy skills longitudinally, even with their autoregressive effects controlled. Analyses of children's spelling mistakes indicated that 97% and 95% of all errors were either morpholexically or orthographically based at times 1 and 2, respectively. Morphologically based spelling errors were also uniquely associated with all three literacy skills across time. Findings underscore the importance of morphological awareness and orthographic knowledge for Chinese literacy acquisition.  相似文献

The goal of this longitudinal study was to describe the average development of word recognition, reading comprehension, vocabulary and spelling of poor and better readers during the elementary school period and to determine whether the differences between these readers increase over a period of 6 years of elementary education. Poor and better readers were defined to belong to the lowest 30% and to the higher 70% of a longitudinal sample, respectively. It appeared that for word recognition the developmental curves for the groups were very distinct and followed similar patterns. For reading comprehension, vocabulary and spelling, the developmental curves showed similar patterns with decreasing differences across grades, however. Clear seasonal effects were found for reading comprehension, vocabulary and spelling, while the seasonal effect for word recognition was restricted to the early grades. It appeared that students with initially poor abilities in word recognition and reading comprehension showed greater improvement over time on reading comprehension, vocabulary and spelling than students with initially better abilities in word recognition and reading comprehension. These findings contradict the existence of a Matthew effect for these skills. For word recognition, a clear differential effect could not be found: the groups did not differ systematically in mean development. The gap between the poor and better decoders did not widen over time for this skill; so a Matthew effect for word recognition was not supported.  相似文献

Dyslexia is a developmental disability affecting the acquisition of reading and writing skills, and its developmental nature makes longitudinal research of great importance. This study therefore investigated the cognitive-linguistic profiles of the typical-functioning dyslexics and high-functioning dyslexics with longitudinal cohorts of Chinese-speaking adolescents diagnosed with childhood dyslexia. These two dyslexic groups of fifty students (with 25 typical-functioning dyslexics) were assessed in Grade 2 (Time 1) and in Grade 8 (Time 2), whereas 25 typically developing controls were assessed at Time 2. Students were administered measures of phonological awareness, morphological skills, visual-orthographic knowledge, rapid naming, verbal working memory, and literacy skills. Results showed that, at Time 2, both dyslexic groups performed less well than the control group on most of the measures. Deficits in rapid naming were particularly salient in both dyslexic groups. Comparing the two dyslexic groups, the typical-functioning dyslexics had more multiple deficits than the high-functioning dyslexics. Findings highlight the importance of rapid naming deficits as potential universal causes of dyslexia and the utility of targeting visual-orthographic knowledge and morphological skills in supporting the development of dyslexic adolescents.  相似文献

Morphological skills have previously been found to reliably predict reading skill, including word reading, vocabulary, and comprehension. However, less is known about how morphological skills might contribute to writing skill, aside from its well-documented role in the development of spelling. This correlational study examines whether morphological skill, as measured by a sentence generation task tapping both derivational morphology and meta-syntactic skills, predicts performance on a standardized essay writing task for fifth- and eighth-grade U.S. students (N = 233), after controlling for grade level, comprehension, and writing fluency. Multilevel analyses indicated that morphological skill and writing fluency were each uniquely predictive of essay quality, and this finding was consistent regardless of whether accurate spelling was required in the morphological task. Our results suggest that morphological skills play an important role in writing, as has been previously documented in reading and spelling.  相似文献

Spelling is a challenge for individuals with dyslexia. Phoneme-to-grapheme correspondence rules are highly inconsistent in French, which make them very difficult to master, in particular for dyslexics. One recurrent manifestation of this inconsistency is the presence of silent letters at the end of words. Many of these silent letters perform a morphological function. The current study examined whether students with dyslexia (aged between 10 and 15 years) benefit from the morphological status of silent final letters when spelling. We compared, their ability to spell words with silent final letters that are either morphologically justified (e.g., tricot, “knit,” where the final “t” is pronounced in morphologically related words such as tricoter, “to knit” and tricoteur “knitter”) or not morphologically justified (e.g., effort, “effort”) to that of a group of younger children matched for reading and spelling level. Results indicated that the dyslexic students’ spelling of silent final letters was impaired in comparison to the control group. Interestingly, morphological status helped the dyslexics improve the accuracy of their choice of final letters, contrary to the control group. This finding provides new evidence of morphological processing in dyslexia during spelling.  相似文献

This study examined the dimensionality of morphological knowledge. The performance of 371 seventh‐ and eighth‐graders on seven morphological knowledge tasks was investigated using confirmatory factor analysis. Results suggested that morphological knowledge was best fit by a bifactor model with a general factor of morphological knowledge and seven specific factors, representing tasks that tap different facets of morphological knowledge. Next, structural equation modelling was used to explore links to literacy outcomes. Results indicated the general factor and the specific factor of morphological meaning processing showed significant positive associations with reading comprehension and vocabulary. Also, the specific factor of generating morphologically related words showed significant positive associations with vocabulary, while specific factors of morphological word reading and spelling processing showed small negative relationships to reading comprehension and vocabulary. Findings highlight the complexity of morphological knowledge and suggest the importance of being cognizant of the nature of morphology when designing and interpreting studies.  相似文献
