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

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

In this study the effect of repeated reading on the acquisition of orthographic knowledge was examined. Acquisition of orthographic knowledge was assessed by the effect of word length on reading speed. We predicted that the effect of length in a set of words and pseudowords would decrease after the repeated reading of these (pseudo)words. The study involved fourth and fifth grade dyslexic children, in addition to normal readers in second and fourth grade. Words and pseudowords ranged from four to six letters and were read 16 times. A length effect was found in the dyslexic and younger normal readers, but not in the older normal readers. The length effect did not change from pre‐test to post‐test, although a large overall improvement in reading speed was found in all groups. These results suggest that repeated reading did not alter the predominantly sub‐lexical reading procedure of the dyslexic and younger normal readers. Implications for the interpretation of the length effect and the notion of word‐specific orthographic knowledge are discussed. 相似文献

In this paper we apply a developmental model of reading to the question of dyslexic subtypes. Groups of normal readers (n=40)
and dyslexic children (n=50), matched on reading level and IQ, were given a comprehensive test battery measuring level of
development of visual, phonological, and orthographic skills. As a group, dyslexics deviated from normal readers of equivalent
reading achievement primarily in phonological skills (spelling-to-sound translation and phonemic analysis), although limited
differences in knowledge of word-specific spellings were also observed. Dyslexics were superior to the younger normal readers
in visual processing of print. Analysis of individual data by reference to the reading level control group revealed three
major subgroups: a group with a specific deficit in phonological processing of print (52 percent), a group with deficits in
processing both the phonological and orthographic features of printed words (24 percent), and a group with phonological deficits
in language (8 percent). The remainder of the sample (16 percent) had specific deficits in visual or orthographic processing
of print, in spelling, or did not differ from the control group. The data support the view that most developmental dyslexics
have a specific language disorder involving some aspect of phonological processing. However, small subgroups with very different
configurations of reading and nonreading difficulties may exist as well.

Does unexpectedly poor spelling in adults result from inferior visual sequential memory? In one experiment, unexpectedly poor spellers performed significantly worse than better spellers in the immediate reproduction of sequences of visual symbols, but in a second experiment, the effect was not replicated. Poor spellers were also no worse at the immediate recognition of symbol sequences. Overall, the results indicate that inferior visual memory is not characteristic of unexpectedly poor spellers. However, they do have less efficient orthographic processing skill: they were significantly slower and more error prone than better spellers at classifying both regularly and strangely spelt words, as well as at detecting letter transpositions in long words. They can thus be considered as subtly worse word readers than better spellers. While the findings question the notion of unexpectedly poor spelling in relation to normal adults, they provide confirmation of the intimate relationship between reading and spelling processes. 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

Several studies have observed that school-aged, reading-disabled children have object-naming problems. In addition, significant
positive relationships between object-naming ability and reading and spelling skills have been observed for this population.
The co-occurrence of these problems has been explained by common underlying phonological deficiencies. Because written language
problems can persist beyond the school-aged years, the purpose of this study was to examine object-naming ability and the
relationship between object naming and written language of adults. Twenty-two adults, half with written language difficulties
and half without, performed four tasks: object naming, object recognition, reading, and spelling. Significant positive relationships
were obtained between object-naming ability and reading ability, object-naming ability and spelling performance, and reading
and spelling performance. In addition to phonological deficiencies, the results indicated that adult poor readers and spellers
lack knowledge of the orthographic structure of words. These findings suggest that problems underlying object naming and written
language do not resolve with cognitive maturation or additional years of experience with language and should be addressed
in the early school-aged years.

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages. 相似文献

Nine children with severe-profound prelingual hearing loss and single-word reading scores not more than 10 months behind chronological age (Good Readers) were matched with 9 children whose reading lag was at least 15 months (Poor Readers). Good Readers had significantly higher spelling and reading comprehension scores. They produced significantly more phonetic errors (indicating the use of phonological coding) and more often correctly represented the number of syllables in spelling than Poor Readers. They also scored more highly on orthographic awareness and were better at speech reading. Speech intelligibility was the same in the two groups. Cluster analysis revealed that only three Good Readers showed strong evidence of phonetic coding in spelling although seven had good representation of syllables; only four had high orthographic awareness scores. However, all 9 children were good speech readers, suggesting that a phonological code derived through speech reading may underpin reading success for deaf children. 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

Subgroups of Finnish dyslexic adults (N = 84)displaying, relative to each other, a distinctivecombination of accuracy and speed of oral text readingwere compared in phonological and orthographicprocessing, verbal short-term memory and readinghabits. Inaccurate phonological decoding appeared todetermine the number of errors made in text reading,while inability to utilize effectively rapid lexicalaccess of words manifested as slow text reading speed.Phonological and orthographic word recognitionprocesses were less tightly integrated among dyslexicthan normal readers. Our results indicate thatadvanced orthographic processing skills might help anumber of the dyslexic readers to compensate for theirserious phonological deficits. The subgroups alsodiffered from each other in reading habits. Arelatively fast reading speed, even with numerouserrors, appears to be more rewarding in everydayreading than a slower but more accurate readingstyle. 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

Little is known about implicit morphological processing in typical and atypical readers. These studies investigate this using a probe detection task with lures sharing morphological, orthographic, or semantic overlap with the probe. Intermediate and advanced readers (reading ages = 9;1–12;9) perform more poorly when there is more linguistic overlap. Novice readers (reading ages = 5;7–8;0) were influenced only by orthographic overlap and not by semantics, indicating that use of orthographic processes typically precedes integration of semantic and morphological skills. Children with otitis media (repeated ear infections) had phonological awareness difficulties but performed age appropriately on the probe detection task, indicating that morphological processing is not constrained by phonology. In contrast, dyslexic children’s performance reflected a failure to remember distinctions between words sharing root morphemes. Dyslexic children are sensitive to morphology but may over-rely on root morphemes. This pattern differed from reading-ability-matched children and children with circumscribed phonological difficulties. 相似文献

Lexical-decision studies with experienced English and French readers have shown that visual-word identification is not only
affected by pronunciation inconsistency of a word (i.e., multiple ways to pronounce a spelling body), but also by spelling
inconsistency (i.e., multiple ways to spell a pronunciation rime). The aim of this study was to compare the reading behavior
of young Dutch readers with dyslexia to the behavior of readers without dyslexia. All students participated in a lexical-decision
task in which we presented pronunciation-consistent words and pseudowords. Half of the pronunciation-consistent stimuli were
spelling consistent and the other half were spelling inconsistent. All three reader groups, that is, students with dyslexia,
age-match students, and reading-match students, read spelling-consistent words faster than spelling-inconsistent words. Overall
reading speed of students with dyslexia was similar to that of reading-match students, and was substantially slower than that
of age-match students. The results suggest that reading in students with or without dyslexia is similarly affected by spelling
inconsistency. Subtle qualitative differences emerged, however, with respect to pseudoword identification. The conclusion
was that the findings were best interpreted in terms of a recurrent-feedback model. 相似文献

The aim of this experiment was to investigate the use of orthographic analogies in conditions that involved making sense of print (picture‐word matching) and pronouncing print (reading aloud) for readers with dyslexia. An adapted version of the classic clue‐word paradigm developed by Goswami was used. Participants were 40 readers with dyslexia and 40 reading‐age‐matched comparison readers. Based on previous theory and research in this area, we predicted that readers with dyslexia would read significantly fewer analogous words than their reading‐age‐matched counterparts. In light of the supposition that word‐picture matching does not require the synthesised pronunciation of a word, we also predicted that readers with dyslexia might be less impaired at analogy use in the picture‐word matching than in the reading aloud condition. However, we found that the dyslexic group read significantly fewer analogous words at post‐test than their reading‐age‐matched peers in both conditions. Also, performance in overall word reading was better for both groups in the word‐picture matching condition. The implications of these results for theory and practice in reading development are discussed, and methodological limitations are noted. 相似文献

This paper explores the relationship between speech and spelling in a single-case study of developmental dyslexia. JM, a developmental dyslexic with a well-documented history of speech, reading and spelling difficulties, was examined when he was 13–14 years old. He still had subtle articulation difficulties causing some disfluency and his use of phonetic voicing was atypical. We argue that these difficulties were recapitulated in his spelling where he was more sensitive to the prosodic aspects of words than normal spellers, exhibiting a strong tendency to spell accurately words which are stressed on the first, rather than the second syllable. He also had more difficulty with phonetic voicing and spelling errors reflected this uncertainty. Thus, when word-specific (orthographic) spelling information is unavailable, JM, like all spellers, must make use of phonological spelling strategies. In his case, these are compromised because of underlying phonological speech problems. It is argued that, while young children make use of a phonological frame on which to organize orthographic information, dyslexics, like JM, who have inadequate phonological representations, are unable to do so. This has a detrimental effect on their acquisition of spelling. 相似文献

The phonological-core variable-orthographic differences (PCVOD) model [van der Leij, & Morfidi (2006). Journal of Learning Disabilities, 39, 74–90] has been proposed as an explanation for the heterogeneity among dyslexic readers in their profiles of reading-related
subskills. The predictions of this model were investigated in a sample of 72 Dutch secondary school students (dyslexics and
controls). First, the PCVOD assumption was confirmed that phonological processing and orthographic competence are independent
contributors to the prediction of reading fluency and spelling. Among the phonological processing tasks, phonological recoding
explained substantial unique variance, but not phonemic awareness or rapid serial naming. Next, the dyslexic readers were
divided into two subgroups based on high (ORTH+) and low levels (ORTH−) of orthographic competence. Both subgroups performed below controls on all measures tapping phonological processing, reading
and spelling but the ORTH+ group performed as well as non-disabled controls on Dutch and English orthographic choice. As predicted by the model, there
were no differences between the subgroups on the tasks that depend on phonological processing, with or without reading. There
were differences on Dutch word reading fluency and spelling. Furthermore, the ORTH+ subgroup outperformed ORTH− on tasks demanding speeded word processing such as ‘flashed’ presentation. This finding was independent of lexicality (words
or pseudowords), language (Dutch or English) or response mode (lexical decision or typing), but restricted to silent reading.
This supports the view that the ORTH+ subgroup is better at identifying larger orthographic units. There was no indication of differences between the subgroups
in reading experience. Our data, therefore, support the PCVOD model.

According to the Grain Size Accommodation hypothesis (Lallier & Carreiras, 2017), learning to read in two languages differing in orthographic consistency leads to a cross-linguistic modulation of reading and spelling processes. Here, we test the prediction that bilingualism may influence the manifestations of dyslexia. We compared the deficits of English monolingual and early Welsh–English bilingual dyslexic adults on reading and spelling irregular English words and English-like pseudowords. As predicted, monolinguals were relatively more impaired in reading pseudowords than irregular words, whereas the opposite was true for bilinguals. Moreover, monolinguals showed stronger sublexical processing deficits than bilinguals and were poorer spellers overall. This study shows that early bilingual reading experience has long-lasting effects on the manifestations of dyslexia in adulthood. It demonstrates that learning to read in a consistent language like Welsh in addition to English gives bilingual dyslexic adults an advantage in English literacy tasks strongly relying on phonological processing. 相似文献

Children aged 11–12 years with a diagnosis of dyslexia (DR) were compared to chronological and reading-age matched poor readers (PR), and two normal reader groups, age-matched (CA) and spelling and reading-age matched (SA–RA), on their processing of inflectional morphology. In comparison to SA–RAs and PRs, the DRs made more spelling errors on regular past tense verb endings relative to irregular past tense verbs and non-verbs. In reading, the DRs took longer than the other groups to make decisions in the written but not oral condition of a tense judgement task. In addition, they were less affected than the PR and SA–RA groups by case altered disruption to the morpheme boundary of inflected verbs. The findings suggest dyslexic children do not show deficits in morphological processing in spoken language, but they are slower at reading and less accurate at spelling regularly inflected verbs compared with normally developing younger children. This difference could plausibly be accommodated within the Phonological Deficit Hypothesis of dyslexia. 相似文献
