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

We argue that the reading of words and text is fundamentally conditioned by the splitting of the fovea and the hemispheric division of the brain, and, furthermore, that the equitable division of labour between the hemispheres is a characteristic of normal visual word recognition. We report analyses of a representative corpus of the eye fixations of normal readers in the realistic reading of text where we compare hemispheric processing, quantified in terms of uncertainty about the orthographic, phonological and semantic representations of the words of the text. The analyses show that normal reading is accurately understood in terms of an equitable division of labour in the construction of the orthographic identity of the word and that, for English, a semantic division patterns closely with the orthographic division. We infer that impaired inter‐hemispheric co‐ordination of orthographic information may be best compensated for by a reliance on the inter‐hemispheric co‐ordination of semantic information, as in phonological dyslexia.  相似文献

This study examines the effects of orthographic neighborhood size (N-size) in relationship with word frequency on the reading aloud of children with and without dyslexia whose language has a consistent orthography. Participants included 22 Italian fourth-grade children with dyslexia and 44 age-matched typically developing readers. Children with dyslexia read low-frequency words with high N-size faster than words that had no neighbors; by contrast, typically developing readers showed no N-size effects, irrespective of word frequency. The facilitating effect of N-size on low-frequency word reading in children with dyslexia indicates that they benefit from lexical activation spreading from dense neighborhoods.  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 two reading level design experiments, matched groups of normal and poor readers were compared with regard to their use of phonological and orthographic information. Experiment 1 used a semantic decision task similar to the task described in the study of Jarvella & Snodgrass (1974). Experiment 1 was aimed to assess the way normal and poor readers, matched on reading level, automatically process phonological and orthographic incongruencies when comparing the singular and plural of nouns. Experiment 2 investigated the automatized processing of uppercase-lowercase letter incongruencies in a same-different task using words and pseudowords. It assessed the role of letter feature cues involved in the initial identification process. Experiment 1 demonstrated that poor readers needed more time for evaluating phonologically incongruent word pairs. No independent effect of orthographic incongruency was found. Experiment 2 showed that, if compared with reading age matched normals, poor readers had more problems with evaluating uppercase-lowercase incongruencies. This orthographic processing problem was particularly prominent when pseudowords were presented. It is concluded that poor readers not only have phonological processing problems, but also have difficulties at the orthographic processing level.  相似文献

This study examined word identification, phonological recoding efficiency, familiar word reading efficiency, orthographic choice for familiar words and serial naming speed as potential correlates of orthographic learning following silent reading in third‐grade children. Children silently read a series of short stories, each containing six repetitions of a different target non‐word. They subsequently read target non‐words faster than homophones and preferred target non‐words to homophones in an orthographic choice task, indicating that they had formed functional orthographic representations of the target non‐words through phonologically recoding them during silent story reading. Target non‐word orthographic choice was correlated with all measures bar non‐symbol naming speed. The association between phonological recoding efficiency and orthographic learning lends support to the hypothesis that self‐teaching occurs through phonological recoding even in silent reading. Our findings were not generally consistent with the view that serial naming speed assesses orthographic learning aptitude.  相似文献

The quality of implicit morphological knowledge in adult Hebrew readers with developmental dyslexia was investigated. The priming paradigm was used to examine whether these adults extract and represent morphemic units similarly to normal readers during online word recognition. The group with dyslexia as a whole did not exhibit priming with visual presentation as opposed to both age- and reading-level controls. Priming was absent when the prime and target words shared a morpheme and even when the prime and the target were identical. Only the students with phonological dyslexia, who exhibited relatively good performance in the orthographic judgment task, exhibited repetition priming but not morphological priming. Strong repetition and morphological priming effects were found for participants with dyslexia when the stimuli were auditory. The implications of the dissociation between visual and auditory priming for the locus of the deficit in morphological processing during word recognition are discussed.  相似文献

A follow‐up study was conducted on AS, previously reported as an English‐Japanese bilingual with monolingual phonological dyslexia in English ( Wydell and Butterworth, 1999 ). It was hypothesised that AS's fundamental deficit which lead to his dyslexia in English would still persist despite him successfully taking a BSc course in an English‐speaking country. AS and his Japanese and English control participants were asked to read aloud a target stimulus first, and then to decide whether the target was a word or nonword. Unlike the control participants, AS showed a marked dissociation between his performance in the lexical (orthographic and phonological) decision and the word naming tasks. Often those words and pseudo‐homophones (e.g. neym), which AS read erroneously, were correct in the decision tasks – the target pseudo‐homophone or word was substituted by another orthographically similar word. The results thus demonstrated that his reading of unfamiliar words or nonwords is essentially based on orthographic approximation using the visual similarities between words. The results confirmed the earlier finding that AS has a core phonological deficit which led to his dyslexia but never affected his reading in Japanese. The results also confirmed that this deficit persists when reading in English. This implies that whatever the neurological abnormality that AS may have, this only affects certain languages, and this abnormality persists with time.  相似文献

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia.  相似文献

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

Two experiments demonstrate that individual differences among normal adult readers, including lexical quality, are expressed in silent reading at the word level. In the first of two studies we identified major dimensions of variability among college readers and among words using factor analysis. We then examined the effects of these dimensions of variability on eye movements during paragraph reading. More experienced readers (who also were higher in reading speed) read words more quickly, especially less frequent words, while readers with higher lexical knowledge showed shorter early fixations, especially for more frequent words. These results suggest that individual differences in reading may reflect differences in the quality of lexical representations and in reading experience, which is a source of lexical quality. In a second study, we controlled the lexical knowledge readers obtained from new words through a training paradigm that varied exposure to a word’s orthographic, phonological, and meaning constituents. Training exposure to orthographic and phonological constituents affected first pass reading measures, and phonological and meaning training affected second pass measures. Incomplete knowledge of word components slowed first pass reading times, compared to both more complete knowledge and no knowledge. Training effects were mediated by individual differences, pointing to lexical quality and reading experience—which, combined reflect reading expertise—as important in word reading as part of text reading.  相似文献

Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers (Experiment 1), but also with young normal readers (Grade 2 and Grade 4 children; Experiment 2) and, even to a larger degree, with readers with dyslexia (Experiments 3 and 4). These experiments suggest that slight increases in inter-letter spacing would improve the readability of texts aimed at children, especially those with dyslexia.  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

The self‐teaching hypothesis suggests that knowledge about the orthographic structure of words is acquired incidentally during reading through phonological recoding. The current study assessed whether visual processing skills during reading further contribute to orthographic learning. French children were asked to read pseudowords. The whole pseudoword letter string was available at once for half of the targets while the pseudoword's sub‐lexical units were discovered in turn for the other half. Then memorisation of the targets’ orthographic form was assessed. Although most pseudowords were accurately decoded, target orthographic forms were recognised more often when the pseudowords entire orthographic sequence was available at once during the learning phase. The whole‐word presentation effect was significant and stable from third to fifth grades. This effect was affected neither by target reading accuracy nor by target reading speed during the learning phase. Results suggest that beyond recoding skills, the ability to process the entire orthographic letter string at once during reading contributes to efficient orthographic learning.  相似文献

Studies on proficient readers showed that speech processing is affected by knowledge of the orthographic code. Yet, the automaticity of the orthographic influence depends on task demand. Here, we addressed this automaticity issue in normal and dyslexic adult readers by comparing the orthographic effects obtained in two speech processing tasks that are or not sensitive to strategies developed by participants. Our finding showed that while participants’ performance in a metaphonological task, which is known to be strategy prone, was affected by their orthographic knowledge regardless of the childhood diagnosis of dyslexia or of their actual reading-related skills, this latter factor significantly modulated the orthographic influence found in a more natural speech recognition task. The finding supports the claim that while any individuals who know a reading code are able to resort to their orthographic knowledge when they process speech, a more profound modification of the speech processing system by the orthographic code takes place only in readers who have reached a certain level of reading expertise.  相似文献

This paper examines the relationship between orthographic depth and reliance upon context for oral reading in English and Hebrew. Research on context effects in English has indicated that the decoding ability of adequate readers is only minimally affected by context. The effect of context may be greater in Hebrew because of its deeper orthography – context may help readers phonologically and semantically disambiguate words whose letters do not provide enough information for grapheme‐to‐phoneme conversion. It is hypothesised that bilingual English‐Hebrew participants would rely more upon context for oral reading of Hebrew than English and that in Hebrew, reading words which are more phonologically ambiguous (high degree of freedom words) would be more affected by context than reading of words which are less phonologically ambiguous (low degree of freedom words). Results support both hypotheses. The findings are consistent with the Orthographic Depth Hypothesis.  相似文献

Bowey, Vaughan and Hansen (1998) have demonstrated that once phonological priming effects have been taken in account, there is no orthographic analogy effect for words with common end patterns (e.g. beak–peak). Goswami (1999) has argued that the study on which this claim is based is methodically flawed. This paper attempted to verify Bowey et al.’s claim by using an improved clue‐word procedure with a group of beginning readers, whose phonological awareness and vocabulary was also assessed. The results indicated that while rime‐based analogies seem to be phonological rather than orthographic in nature, beginning readers are able to use an orthographic analogy strategy when reading words that have similar beginnings (e.g. beak–bean).  相似文献

Deaf people often achieve low levels of reading skills. The hypothesis that the use of phonological codes is associated with good reading skills in deaf readers is not yet fully supported in the literature. We investigated skilled and less skilled adult deaf readers' use of orthographic and phonological codes in reading. Experiment 1 used a masked priming paradigm to investigate automatic use of these codes during visual word processing. Experiment 2 used a serial recall task to determine whether orthographic and phonological codes are used to maintain words in memory. Skilled hearing, skilled deaf, and less skilled deaf readers used orthographic codes during word recognition and recall, but only skilled hearing readers relied on phonological codes during these tasks. It is important to note that skilled and less skilled deaf readers performed similarly in both tasks, indicating that reading difficulties in deaf adults may not be linked to the activation of phonological codes during reading.  相似文献

There is an increasing number of studies which demonstrate that readers in more transparent orthographies than English, such as Italian, Spanish, Turkish, Greek and German have little difficulty in decoding written words, while English children have many more problems. Increasingly, lack of orthographic transparency in English is seen as having a powerful negative effect on the development of reading skills in English-speaking children. There is evidence that English-speaking children who fail to acquire reading skills may fall into two distinct categories: those who would succeed in languages, other than English, that have greater orthographic consistency; and, those who would still have problems even with perfect orthographic transparency. The first, larger, group are let down by the interaction of poor teaching methods and an incomprehensible system of orthography. At Hull University’s Institute for Learning, word factors associated with poor spelling and reading have been identified. We have found three factors which account for the relative ease with which pupils can spell words: frequency of the word in the English language, length of the word, and the presence of “tricky” letters or letter combinations. Data is presented illustrating our predictive model of spelling which enables word difficulty to be calculated from the characteristics of English words. The implications the model has for teaching and learning English is elaborated, with particular reference to the most common 150 words in the English language.  相似文献
