Given the well-acknowledged phonological deficit found in dyslexic children, this study was aimed at investigating graphophonological processes in dyslexic readers of French over a 1-year period. Among the different types of phonological processing can be distinguished those related to phonological awareness based on knowledge of the oral language and graphophonological processes based on correspondences between the oral and the written language. In this study, we evaluated graphophonemic and graphosyllabic processes using, in each case, two different tasks varying in the degree of cognitive constraint associated with the task (CC- vs CC+). Twenty 11 year-old dyslexic students were compared with younger normal-readers of the same reading level (RA, n=26) and to normal-readers of the same age (CA, n=24). Two variables were considered in the analyses: accuracy and response latency. Results show that dyslexic readers do process written items at the graphophonological level. Also, results indicate main effects of task (CC- vs CC+), time (T1 vs T2), and group (DYS vs RA vs CA). In general, dyslexic participants' performances are comparable to those of RA and differ from those of CA.  相似文献

The purpose of the present study was twofold: (a) to examine the extent to which Chinese dyslexic children experience deficits in phonological and orthographic processing skills and (b) to examine if Chinese dyslexia is associated with deficits in Planning, Attention, Simultaneous, and Successive (PASS) processing. A total of 27 Grade 4 children with dyslexia (DYS), 27 Grade 4 chronological age (CA) controls, and 27 Grade 2 reading age (RA) controls were tested on measures of phonological awareness, rapid naming, phonological memory, PASS, reading accuracy, and reading fluency. The results indicated that the DYS group performed significantly poorer than the CA and RA groups on both measures of phonological awareness and on a measure of orthographic processing but comparably to the RA group on a measure of rapid naming and both measures of phonological memory. In regard to the PASS processing skills, the DYS group performed worse than the CA controls on Successive and Simultaneous processing but comparably to the RA group on all PASS processing skills. Implications of these findings for early identification and intervention of reading difficulties are discussed.  相似文献

Two groups of deaf children, aged 8 and 14 years, were presented with a number of tasks designed to assess their reliance on phonological coding. Their performance was compared with that of hearing children of the same chronological age (CA) and reading age (RA). Performance on the first task, short-term recall of pictures, showed that the deaf children's spans were comparable to those of RA controls but lower than CA controls. For the older deaf children, short-term memory span predicted reading ability. There was no clear evidence that the deaf children were using phonological coding in short-term memory when recall of dissimilar items was compared with recall of items with similarly sounding names. In the second task, which assessed orthographic awareness, performance of the deaf children was similar to that of RA controls although scores predicted reading level for the deaf children but not the hearing. The final task was a picture spelling test in which there were marked differences between the deaf and hearing children, most notably in the number of spelling refusals (which was higher for the deaf children in the older group than their RA controls) and the percentage of phonetic errors (which was considerably lower for both groups of deaf children than for any of the hearing controls). Overall these results provide support for the view that deaf children place little reliance on phonological coding.  相似文献

Previous studies show that many students with reading and spelling problems have a lack of progress in reading and spelling skills after years of special education services. The aim of the study is to evaluate the reading and spelling skills of Finnish children in grades 1 and 2 receiving part-time special education from special education teachers for reading and spelling difficulties (RSD) and for RSD with other learning difficulties. In this study, the focus is in the roles of the form and the amount of part-time special education in reading and spelling skills development. Of 152 children involved in the study, 98 received part-time special education for RSD, and 54 did not have RSD and did not receive special education. The results showed that the reading and spelling skills of students with RSD lagged behind age level and that students with overlapping difficulties exhibited even slower development. Small group education and a moderate amount of part-time special education (approximately 38 h per year) predicted faster skill development, whereas individual and a large amount of special education (more than 48 h per year) were related to slower skill development and broader difficulties.  相似文献

This study examined the role of variability and change in children’s strategy performance within the context of spelling. The spelling ability of 34 eight‐ to nine‐year‐olds was examined using an experimental spelling task comprising 45 items, which varied with regard to rime unit frequency. The spelling task incorporated a series of consistent, unique, and exception word items. Children were tested on the same spelling task on three separate occasions over a period of three months. Performance was examined using immediately retrospective verbal self‐reports after the presentation of every word. The findings showed that children spelt words strategically and were adaptive in their strategy selection, showing a general change from using less efficient backup strategies to using more efficient direct retrieval methods over time. Finally, while those less skilled in spelling showed a greater reliance on less efficient backup strategies, the skilled spellers mainly retrieved the correct spellings from memory. However, accuracy only improved across time intervals for each skill group when spelling unique word items. Overall, the findings illustrate the benefits of using a detailed microgenetic approach to assess the progress children make in learning to spell.  相似文献

We investigated the spelling of derivational and inflectional suffixes by 10–13-year-old Greek children. Twenty children with dyslexia (DYS), 20 spelling-level-matched (SA) and 20 age-matched (CA) children spelled adjectives, nouns, and verbs in dictated word pairs and sentences. Children spelled nouns and verbs more accurately than adjectives and inflections more accurately than derivational suffixes. DYS children performed worse than CA in all cases and worse than SA in verb inflections, but similar to SA in all the remaining cases, consistent with a delayed rather than deviant performance pattern. Qualitative analysis showed that uncommon vowel graphemes were often replaced by more common patterns. Children with dyslexia may have weaknesses in grasping morphological information and/or in applying this knowledge to spell word suffixes.  相似文献

This study examined the use of orthographic and phonological deletion strategies by children in the 6–16‐year age range. Children from Grades 1 to 10 (n=191) were presented either visually or orally isolated words and were asked to pronounce these words using either an orthographic (spelling) strategy following mental deletion of one letter, or a phonological (sounding) strategy following mental deletion of one sound. All children performed additional reading and spelling tasks in which they read and spelt all the words and derivatives from the deletion tasks. Analysis of variance revealed that younger readers were more accurate when using phonological strategies than when using orthographic strategies, whereas older readers showed superior orthographic and phonological processing abilities. Generally the results supported the suggestion that phonological and orthographic processing ability increase with age, and that the increase in these abilities with age is not solely dependent on reading and spelling ability.  相似文献

Children with specific language impairments (SLI) have difficulties in producing written text. It was hypothesised that the constraints on writing in children with SLI were similar to typically developing younger children with the same level of vocabulary knowledge. Twenty‐three children with SLI (aged 10:5) were matched with 23 children for chronological age (CA) and 23 children for vocabulary levels (VC). Children with SLI performed significantly below their CA peers but not their VC peers on all aspects of writing including spelling. Regression analyses indicated that written text measures of spelling errors and oral language measures of vocabulary were significant predictors of writing products for both the children with SLI and their VC peers. This highlights the importance of oral and written language for the quality of children's written text and indicates that the writing of children with SLI was commensurate with their vocabulary and spelling levels. The results point to the role of both phonological and non‐phonological processes in written text production in struggling writers.  相似文献

This study tested the predictions of thephonological and double deficit hypotheses byexperimentally examining speech perception,phoneme awareness, lexical retrieval (serialand discrete), articulatory speed, and verbalSTM in school age child (N = 35) and adolescent(N = 36) dyslexics, and both chronological age(CA) and reading age (RA) controls. Theresults confirmed the findings of previousstudies of a deficit in phoneme awareness indevelopmental dyslexia. At both age levels,dyslexics performed significantly more poorlythan both their CA and RA controls. Althoughdeficits in the other processes investigated,particularly in rapid serial naming, were alsoapparent, they were not as clear-cut as thedeficit in phoneme awareness. In general,definite evidence of a deficit in rapid serialnaming was limited to the more severelyimpaired dyslexics. Furthermore, although rapidserial naming contributed independent variationto various literacy skills, its contributionwas modest relative to the contribution ofphoneme awareness, regardless of whether theliteracy skill relied more or less heavily onphonological or orthographic coding skills. Further analyses suggested that variation inrapid serial skill is particularly importantfor fluent reading of text, whereas phonemeawareness is particularly important for thedevelopment of the ability to read byphonologically recoding letters or groups ofletters in words into their phonological codes.This explains the relatively strongcontribution of phoneme awareness to readingand spelling ability in general. In sum, thephonological hypothesis offers a moreparsimonious account of the present resultsthan the double deficit hypothesis.  相似文献

To identify effective treatment for both the spelling and word decoding problems in dyslexia, 24 students with dyslexia in grades 4 to 9 were randomly assigned to treatments A (n?=?12) or B (n?=?12) in an after-school reading-writers’ workshop at the university (thirty 1-h sessions twice a week over 5 months). First, both groups received step 1 treatment of grapheme–phoneme correspondences (gpc) for oral reading. At step 2, treatment A received gpc training for both oral reading and spelling, and treatment B received gpc training for oral reading and phonological awareness. At step 3, treatment A received orthographic spelling strategy and rapid accelerated reading program (RAP) training, and treatment B continued step 2 training. At step 4, treatment A received morphological strategies and RAP training, and treatment B received orthographic spelling strategy training. Each treatment also had the same integrated reading–writing activities, which many school assignments require. Both groups improved significantly in automatic letter writing, spelling real words, compositional fluency, and oral reading (decoding) rate. Treatment A significantly outperformed treatment B in decoding rate after step 3 orthographic training, which in turn uniquely predicted spelling real words. Letter processing rate increased during step 3 RAP training and correlated significantly with two silent reading fluency measures. Adding orthographic strategies with “working memory in mind” to phonics helps students with dyslexia spell and read English words.  相似文献

The purpose of this pilot study was to assess the potential for computer-assisted instruction (CAI) to enhance number combination skill among children with concurrent risk for math disability and reading disability. A secondary purpose was to examine the effects of CAI on spelling. At-risk students were assigned randomly to math or spelling CAI, which they received in 50 sessions over 18 weeks. Acquisition and transfer effects were assessed. The results indicated that math CAI was effective in promoting addition but not subtraction number combination skill and that transfer to arithmetic story problems did not occur. Spelling CAI effects were reliable on acquisition and transfer spelling measures, with small to moderate effect sizes on transfer to reading measures. These results provide the basis for additional work with larger samples.  相似文献

A pervasive assumption in most accounts of normal reading and spelling development is that phonological coding is important early in development but is subsequently superseded by faster, orthographic coding which bypasses phonology. We call this assumption, which derives from dual process theory, the developmental bypass hypothesis. The present study tests four specific predictions of the developmental bypass hypothesis by comparing dyslexics and nondyslexics from the same families in a cross-sectional design. The four predictions are: 1) That phonological coding skill develops early in normal readers and soon reaches asymptote, whereas orthographic coding skill has a protracted course of development; 2) that the correlation of adult reading or spelling performance with phonological coding skill is considerably less than the correlation with orthographic coding skill; 3) that dyslexics who are mainly deficient in phonological coding skill should be able to bypass this deficit and eventually close the gap in reading and spelling performance; and 4) that the greatest differences between dyslexics and developmental controls on measures of phonological coding skill should be observed early rather than late in development. None of the four predictions of the developmental bypass hypothesis were upheld. Phonological coding skill continued to develop in nondyslexics until adulthood. It accounted for a substantial (32–53 percent) portion of the variance in reading and spelling performance in adult nondyslexics, whereas orthographic coding skill did not account for a statistically reliable portion of this variance. The dyslexics differed little across age in phonological coding skill, but made linear progress in orthographic coding skill, surpassing spelling-age (SA) controls by adulthood. Nonetheless, they didnot close the gap in reading and spelling performance. Finally, dyslexics were significantly worse than SA (and Reading Age [RA]) controls in phonological coding skill only in adulthood.

Children's early spelling attempts (invented spellings) and underlying component skills were evaluated in a sample (N = 115) of 5-year-old children. Letter-sound knowledge and phoneme awareness were shown to be important predictors of invented spelling performance in this age group. The results also showed associations between invented spelling and measures of orthographic awareness and morphological processing. The findings support the view that invented spelling is a developmentally complex and important early literacy skill that involves phonemic awareness, letter sound knowledge, and other oral language skills and orthographic knowledge.  相似文献

We examined whether the overlapping waves model, originally developed to account for strategy choices in arithmetic, could also account for strategy choices in spelling. The contrast was of particular interest because arithmetic is an algorithmic domain (a domain that includes strategies that always yield correct answers if executed properly), whereas spelling is not. Thirty first-grade students spelled words under 2 conditions, and 23 of these students were retested in second grade. Trial-by-trial analysis of strategy use was used to identify which strategies first and second graders used, how adaptively they chose among them, how effective the strategies were, and what changes occurred from first to second grade along each dimension. The model proved useful for understanding the development of spelling, despite the fact that explicit use of backup strategies had a minimal impact on accuracy. Implications for understanding adaptive strategy choices in algorithmic and nonalgorithmic domains are discussed.  相似文献

The spellings of 39 profoundly deaf users of cochlear implants, aged 6 to 12 years, were compared with those of 39 hearing peers. When controlled for age and reading ability, the error rates of the 2 groups were not significantly different. Both groups evinced phonological spelling strategies, performing better on words with more typical sound–spelling correspondences and often making misspellings that were phonologically plausible. However, the magnitude of these phonological effects was smaller for the deaf children than for hearing children of comparable reading and spelling ability. Deaf children with cochlear implants made the same low proportion of transposition errors as hearing children. The findings indicate that deaf children do not rely primarily on visual memorization strategies, as suggested by previous studies. However, deaf children with cochlear implants use phonological spelling strategies to a lesser degree than hearing peers.  相似文献

The aim of the study was to investigate the effectiveness of a strategic keyboard training program for improving the spelling performance of children with mild disabilities. The sample consisted of 36 mildly disabled students divided into two groups: 18 learning disabled students, and 18 educable mentally retarded students. The teachers used strategic procedures emphasising awareness of word structure and spelling strategies, combined with keyboard training, for a duration of three months (45‐minute sessions, twice weekly). The results demonstrated a significant decrease in spelling errors, as assessed through computer typing and handwriting. However, the comparisons between the group achievements of the learning disabled and mentally retarded children did not reveal significant differences in the development of the spelling performance. Analysis of the results, and of the four case‐studies, pin‐pointed attention onto the initial individual differences in the spelling performance, and onto the students’ individual learning style during training, emphasising the need for an individualised approach in remedial computerised spelling procedures.  相似文献
