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

The major findings of several research projects that investigated dyslexic college students are summarized in this paper. Consistent findings of these investigations led to the following conclusions. 1) Developmental dyslexia is a syndrome made up of the following four symptoms: slow rate of reading, error-prone oral reading, poor written spelling, and grammatically incorrect writing; 2) all these symptoms could be traced to a poor mastery of the grapheme-phoneme relational rules; 3) developmental dyslexia can be found in subjects who appear to have adequate oral language skills; 4) ex-dyslexics who appear to be “poor spellers but good readers” have subtle reading deficits; and 5) the 20 dyslexic subjects investigated appear to constitute a homogeneous group which raises questions regarding dyslexia subtypes.  相似文献

Dyslexic readers are typically regarded as being treatment resistant when exposed to reading intervention. The aim of this study was to determine the practical utility of employing an instrument such as the phonological assessment battery (PhAB) as a means of identifying dyslexic (with poor phonological processing skills) from non-dyslexic older low-progress readers. A sample of 22 older low-progress readers was assessed on the PhAB and also on a variety of reading and spelling measures prior to receiving and following an intensive, systematic, skills-based literacy intervention program for two terms. The group as a whole made substantial and significant mean gains on all reading and spelling measures but there were no appreciable differences in gain between those students identified as dyslexic and those who were not. Moreover, none of the PhAB subtest scores predicted size of gains. The intensive literacy instruction, however, appeared to improve performance on several subscales of the PhAB. These results provide evidence of the need for intensive literacy remediation for all low-progress readers, regardless of their categorisation, and lend support to those who advocate a non-categorical approach to addressing reading disability. Identifying dyslexic readers may not be helpful and teaching phonological awareness as a separate component may not be necessary to meet the needs of older low-progress readers.  相似文献

This exploratory study aimed to evaluate the spelling of derived words by dyslexic adolescents and to verify whether this is associated with lack of vocabulary and/or morphological knowledge. A cross-sectional reading level-design was employed in order to determine differences in spelling, derivational morphology and vocabulary tasks between dyslexic students aged 13+ and age-matched and reading level matched control groups. The study confirmed a profound spelling impairment of dyslexic students in comparison with two control groups but this was not associated with poor vocabulary in relation with their age-peers. In contrast, they exhibited lower levels of morphological knowledge than age-matched controls but equivalent with the reading level controls. These results are interpreted in the light of current developmental models of spelling that support a reciprocal interaction between spelling and metamorphology.  相似文献

Academic problems of the dyslexic child often persist in adult life. Such problems as spelling can interfere with the performance of such adult learners in college. Federal legislation requires reasonable accommodation for these students. At some colleges, this consists of allowing use of tape recorders in lectures and sometimes allowing extra time on examinations. Remediation of reading, writing, and spelling among dyslexic college students is often not addressed. This study reports the use of a modified Orton-Gillingham approach in comparison with a nonphonetic approach and with a group receiving no remediation. The results indicate a significant increase in spelling performance for the group receiving the modified Orton-Gillingham remediation. This contrasts with no significant change in the group receiving nonphonetic remediation and in the control group (no remediation), and indicates that adulthood is not too late for appropriate intervention for the dyslexic student. Colleges offering such intervention and the students receiving it will benefit from improved performance.  相似文献

A central focus in remedial teaching is the generalisation of responses to contexts in which a student has never been explicitly instructed. Remarkably little is known about how and when generalisation occurs. In this article we examine generalisation effects in the context of spelling. Three areas are discussed: generalisation between spelling and reading, generalisation to untrained sound-letter-correspondences and generalisation to untrained unpredictable words. The research presented indicates both that reading training often leads to spelling improvements and that spelling training leads to reading improvements. There is a tendency for spelling training to be more likely to induce changes in reading than vice versa. In addition, for unpredictable words, generalisation is more likely to occur for words of high frequency and words that are orthographically similar to many other words. We conclude that a better understanding of how generalisation occurs will enable us to improve the efficiency and effectiveness of remedial spelling programmes.  相似文献

This paper investigates Spanish dyslexic spelling abilities: specifically, the influence of syllabic linguistic structure (simple vs consonant cluster) on children's spelling performance. Consonant clusters are phonologically complex structures, so it was anticipated that there would be lower spelling performance for these syllabic structures than in simple ones, because of the poor phonological processing of dyslexic children. The participants were 31 dyslexic children, 31 chronological age‐matched children and 31 reading level‐matched children. A dictation task with words and pseudowords (with and without consonant clusters) was used. Word lexical frequency was controlled. The results show that the spelling of consonant clusters presents difficulties for dyslexic spelling performance despite this structure being orthographically consistent. Dyslexic children present a higher performance difference in items with consonant clusters than in simple items, compared with typically developing children. The work raises questions about the items used for the identification of dyslexic children's difficulties.  相似文献

This study tested the hypothesis that when a stringent criterion of normal IQ is applied in the selection of dyslexic readers, and when dyslexics, nondyslexic poor readers, and normal readers are matched on reading comprehension — rather than word reading — significant differences among these groups can be demonstrated. Two groups of poor readers from primary grades, one with normal IQ (dyslexics) and the other with below-average IQ (nonspecific reading disabled, NSRD) were matched for reading comprehension with a group of younger normal readers. The dyslexic group was found to be inferior to the other two groups in tests of decoding and spelling. The dyslexic readers were more context-dependent for word recognition than the other two groups. The NSRD group did not differ from the normal readers in these aspects but had the worst performance on a test of inferential comprehension. It was concluded that dyslexics differ from normal readers and low-IQ poor readers in word and nonword reading skills and context-dependency for reading. A group of six adult dyslexics were also found to be deficient in decoding skills. A lack of unanimity in the use of certain terminology, a substantial age difference between low-IQ poor readers and normals, and the difference in the criteria used for matching the different groups could be factors that can explain the disagreements seen between the findings of the present study and those reported by some other studies. Potential problems associated with reading-age matched experimental design are discussed.  相似文献

College students, scoring average to above-average on WRAT-R subscales for reading and spelling, made match/nonmatch judgments on word pairs either on the basis of phonological similarity (a rhyme match) or orthographic similarity (a visual match). Word pairs rhymed and looked similar, rhymed but looked dissimilar, or looked similar but did not rhyme. Word pairs for which a nonmatch decision had to be made, despite similarity in the irrelevant dimension, produced significantly more errors and longer response latencies. Poorer readers were less vulnerable to phonological interference when making visual discriminations, and poorer readers and spellers were more vulnerable to orthographic interference when making rhyme matches. Results showed that a deficiency in phonological coding and an over-reliance upon orthographic coding, often observed in dyslexic children, can also be seen in relatively poor readers and spellers within a normal adult population.  相似文献

In this study we propose a classification system for spelling errors and determine the most common spelling difficulties of Greek children with and without dyslexia. Spelling skills of 542 children from the general population and 44 children with dyslexia, Grades 3–4 and 7, were assessed with a dictated common word list and age-appropriate passages. Spelling errors were classified into broad categories, including phonological (graphophonemic mappings), grammatical (inflectional suffixes), orthographic (word stems), stress assignment (diacritic), and punctuation. Errors were further classified into specific subcategories. Relative proportions for a total of 11,364 errors were derived by calculating the opportunities for each error type. Nondyslexic children of both age groups made primarily grammatical and stress errors, followed by orthographic errors. Phonological and punctuation errors were negligible. Most frequent specific errors were in derivational affixes, stress diacritics, inflectional suffixes, and vowel historical spellings. Older children made fewer errors, especially in inflectional suffixes. Dyslexic children differed from nondyslexic ones in making more errors of the same types, in comparable relative proportions. Spelling profiles of dyslexic children did not differ from those of same-age children with poor reading skills or of younger children matched in reading and phonological awareness. In conclusion, spelling errors of both dyslexic and nondyslexic children indicate persistent difficulty with internalizing regularities of the Greek orthographic lexicon, including derivational, inflectional, and word (stem) families. This difficulty is greater for children with dyslexia.  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 present study retrospectively examined early difficulties with phonological coding and phonemic segmentation of German children who after four years in school were diagnosed as dyslexic. German, in comparison to English, exhibits rather simple and straight-forward grapheme-phoneme correspondences, and the initial teaching approach was phonics oriented. Despite these favorable circumstances for the acquisition of phonological coding, the majority of the later dyslexic children had particular difficulties with the accurate reading of nonwords and of unfamiliar words after about seven months of reading instruction. However, there were enormous differences between the dyslexic children. Two of them were completely unable to blend phonemes into pronunciations, another seven were slow and error prone decoders, and three children had slow and laborious pronunciation assembly as the core problem. The majority of the later dyslexic children also exhibited phonemic segmentation deficits as tested with a nonword spelling task and a phoneme reversal task. In correspondence with findings from older German dyslexic children, the early difficulties with accurate phonological coding and phonemic segmentation were no longer found at the end of grade four. Children then suffered from very slow reading and poor spelling. In general, the difficulties of German dyslexic children emphasize the phonological impairment account of dyslexia. More specifically, these findings suggest that the assembly of letter sounds into pronunciations is particularly affected in the early phase of learning to read a consistent orthography.  相似文献

This study examined the effects of training in phonological awareness on kindergarten children. Comparisons of children at risk (i.e., children with initially low levels of metalinguistic ability) with initially average and advanced children revealed that training gains were similar for all of these groups. Furthermore, training had comparable long-term effects on reading and spelling in Grades 1 and 2 for each group. In fact, the trained children at risk showed better reading and spelling performance than a randomly selected control group. Although considerable individual differences in training effectiveness were found Within the group of at-risk children, there was clear evidence that the training program substantially reduced the risk of becoming dyslexic in school.  相似文献

Reading research supports the necessity for directly teaching concepts about linguistic structure to beginning readers and to students with reading and spelling difficulties. In this study, experienced teachers of reading, language arts, and special education were tested to determine if they have the requisite awareness of language elements (e.g., phonemes, morphemes) and of how these elements are represented in writing (e.g., knowledge of sound-symbol correspondences). The results were surprisingly poor, indicating that even motivated and experienced teachers typically understand too little about spoken and written language structure to be able to provide sufficient instruction in these areas. The utility of language structure knowledge for instructional planning, for assessment of student progress, and for remediation of literacy problems is discussed. The teachers participating in the study subsequently took a course focusing on phonemic awareness training, spoken-written language relationships, and careful analysis of spelling and reading behavior in children. At the end of the course, the teachers judged this information to be essential for teaching and advised that it become a prerequisite for certification. Recommendations for requirements and content of teacher education programs are presented.  相似文献

The major purpose of this study was to test the effectiveness of the Project Success Summer Program (PSSP) for adult dyslexics. Using a pretest-posttest one-group design, the experimenter examined the effects of PSSP’s intensive eight-week program on the reading and spelling test scores of subjects (n=63). Data analysis indicated subjects’ reading and spelling scores improved significantly in five areas: reading of real words, passage reading rate, reading comprehension, spelling, and phoneme deletion. A second purpose of the study was to determine the best predictors of reading comprehension from among the study’s eight pretest reading and spelling measures. Regression analysis revealed that passage reading rates and individual word reading rates were the best predictors of reading comprehension scores. Interpretation of the results of this study suggest that training in phonological skills can improve poor readers’ basic decoding skills resulting in improved reading rate, comprehension 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

Abstract

This research examined differences between dyslexic, poor and normal readers who learn in the same educational framework, across various linguistic and meta-linguistic skills in Hebrew as the first language (L1) and English as a foreign language (FL), following an intervention program focusing on English linguistic skills. The participants included 124 sixth graders divided into an experimental and a control group, where each group was divided into dyslexic, poor and normal readers. The experimental group participated in an intervention program in English, constructed to the requirements of this research, in addition to the regular sixth-grade English curriculum. All participants were administered a battery of tests in English and Hebrew: phonology, morphology, syntax, semantics, orthography, decoding, word recognition, reading fluency, dictation, spelling and reading comprehension before and after the intervention program. More significant differences in most linguistic and meta-linguistic skills improvement in English and in Hebrew were found in the experimental group compared to the control group, with the most significant improvement exhibited by the dyslexic readers. The findings indicate the contribution of the intervention program in English for improving linguistic and meta-linguistic skills in both languages among all readers, and especially among dyslexic readers. Enlargement of the curriculum in English appears to expand their potential, and their improvement is better than that of the poor and normal readers.  相似文献

Generally, a person who is diagnosed as dyslexic remains diagnosably dyslexic all his/her life. However, occasionally, an individual compensates for his/her difficulties in some way, and by adulthood is no longer diagnosably dyslexic. In what ways are these compensated dyslexics different from both dyslexics and nondyslexics? We compared IQ, achievement test, and spelling error scores in adult dyslexics, adult nondyslexics, and adult compensated dyslexics (N=25) in the two studies reported here. The second study differed from the first in that the subjects were matched for age, education, IQ, and SES. In both studies, compensateds were significantly different from nondyslexics on the WRAT Spelling subtest and Reading Quotient scores. In the second study the compensateds differed from the nondyslexics in total raw score and average reading speed on Gray Oral Reading Test. On the other hand, they were different from dyslexics on all reading and spelling variables in both studies, except for PIAT Reading Comprehension in Study 2. Finally, in Study 2, the compensateds were different from both dyslexics and nondyslexics in average reading speed. In conclusion, it appears that compensation does not result from differences in IQ, education, or SES, though it may be influenced to some extent by sex. Compensateds appear very similar to nondyslexics in their reading and spelling skills; however, there appears to be a difference in the automaticity with which they apply these skills.  相似文献

This paper begins by presenting theoretical arguments and empirical evidence to support the idea that morpheme analysis strategies play a part in word recognition in reading, and in dyslexia in particular. The results of two studies are presented which indicate that dyslexic adolescents use recognition of root morphemes as a compensatory strategy in reading of both single words and coherent text. Furthermore, the evidence is reviewed that the use of morpheme recognition as a strategy in reading to some extent depends on the linguistic awareness of morphemes in spoken language. Finally, results from a pilot study of the effects of morphological awareness training of dyslexic students are presented which suggest that it may be possible to improve the awareness of morphology independently of phoneme awareness, and that such a training may have positive effects on reading of coherent text and on the accurate spelling of morphologically complex words.  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
