The objective of the present study was to examine the contribution of lexical and nonlexical processes to skilled reading
and spelling in Persian. Persian is a mixed orthography that allows one to study within one language characteristics typically
found in shallow orthographies as well as those found in deeper orthographies. 61 senior high-school students (mean age = 17;
8, SD = 4 months) attending schools in Iran were tested on reading and spelling of words and nonwords. The word stimuli differed
in terms of reading transparency (transparent when all phonemes have corresponding letters vs. opaque when short vowels were
not marked with a letter) and spelling polygraphy (nonpolygraphic phonemes vs. polygraphic phonemes). The nonwords were transparent
and nonpolygraphic. The reading results showed that both transparent and opaque words were read faster than nonwords, and
that transparent words were read faster than opaque words. Moreover, both transparent and opaque words were affected by word
frequency. These findings suggest that skilled readers of Persian relied on lexical processes to read words. In contrast,
the spelling results failed to show a word-advantage effect suggesting that skilled spellers of Persian rely on nonlexical
processes to spell words. Moreover, orthographic complexity also affected spelling. Specifically, nonpolygraphic words were
spelled faster than polygraphic words for both transparent and opaque words. Taken together, the findings showed that skilled
reading and spelling in Persian rely on different underlying processes. 相似文献

The lexical quality hypothesis (LQH) claims that variation in the quality of word representations has consequences for reading skill, including comprehension. High lexical quality includes well-specified and partly redundant representations of form (orthography and phonology) and flexible representations of meaning, allowing for rapid and reliable meaning retrieval. Low-quality representations lead to specific word-related problems in comprehension. Six lines of research on adult readers demonstrate some of the implications of the LQH. First, large-scale correlational results show the general interdependence of comprehension and lexical skill while identifying disassociations that allow focus on comprehension-specific skill. Second, word-level semantic processing studies show comprehension skill differences in the time course of form-meaning confusions. Studies of rare vocabulary learning using event-related potentials (ERPs) show that, third, skilled comprehenders learn new words more effectively and show stronger ERP indicators for memory of the word learning event and, fourth, suggest skill differences in the stability of orthographic representations. Fifth, ERP markers show comprehension skill differences in meaning processing of ordinary words. Finally, in text reading, ERP results demonstrate momentary difficulties for low-skill comprehenders in integrating a word with the prior text. The studies provide evidence that word-level knowledge has consequences for word meaning processes in comprehension. 相似文献

Using a large adult reading database, we examined the relationships between high-level and low-level reading skills and between
multiple reading skills, general cognitive ability, and reading comprehension ability. A principal components analysis found
partial dissociability between higher-level skills including reading comprehension, vocabulary and print exposure, and lower-level
skills including decoding and spelling in adult readers. Furthermore, follow-up regression analyses showed that the high-level
sub-skills (e.g., vocabulary and print exposure) were significantly better predictors of reading comprehension ability than
the low-level skills (e.g., decoding and spelling) in adult skilled readers. These findings suggest that higher-level and
lower-level skills are dissociable in adult skilled readers and that higher-level skills are more strongly related to comprehension
ability in adults. 相似文献

The lexical quality hypothesis assumes that skilled readers rely on high quality lexical representations that afford autonomous
lexical retrieval and reduce the need to rely on top-down context. This experiment investigated this hypothesis by comparing
the performance of adults classified on reading comprehension and spelling performance. ‘Lexical experts’, defined by above
average performance on both measures, were compared with individuals who are good readers/poor spellers, poor readers/good
spellers, or poor on both measures. Sentences finishing with a homograph (e.g., She danced all night at the ball) were followed by a probe word and participants had to decide whether it had occurred in the sentence. Critical probe words
were related to either the sentence-congruous or the sentence-incongruous meaning of the homograph (e.g., waltz vs. throw). Lexical experts showed less interference from related probes than the other groups. When the sentences were presented at
fast rates, poorer spellers showed interference for sentence-congruous but not sentence-incongruous probes. However, at slower
presentation rates, all groups showed equivalent interference for both types of probes. The results support the lexical quality
hypothesis by showing that high quality lexical representations, indexed by better spelling, are associated with reduced reliance
on sentence context.

The dual‐route model of reading proposes distinct lexical and sub‐lexical procedures for word reading and spelling. Lexically reliant and sub‐lexically reliant reader subgroups were selected from 78 university students on the basis of their performance on lexical (orthographic) and sub‐lexical (phonological) choice tests, and on irregular and nonword naming. In spelling of irregular words and nonwords to dictation, the group comparisons failed to support the dissociative predictions for lexical and sub‐lexical reliance that were derived from the dual‐route model: lexical readers were not superior to sub‐lexical readers on spelling irregular words as well as inferior to sub‐lexical readers on spelling regular letter strings (nonwords). In line with a single‐route view, print exposure and phonological coding (nonword naming accuracy) appear to be key factors in the effective learning of both regular and irregular words. 相似文献

Dyslexic difficulties in lexical stress were compared to difficulties in segmental phonology. Twenty-nine adolescents with dyslexia and 29 typically developing adolescents, matched on age and nonverbal ability, were assessed on reading, spelling, phonological and stress awareness, rapid naming, and short-term memory. Group differences in stress assignment were larger than in segmental phonology in reading and spelling pseudowords but not words, indicating a fragility of explicit processes that manipulate stress representations. Despite impaired stress performance in dyslexia at the group level, individual variability failed to reveal evidence for a stress-specific deficit or for a distinct stress-impaired subgroup. 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

The purpose of this study was to assess the role that phonological, orthographic, and contextual sources of information play
in a group of adults who were learning to read compared to adult skilled readers. Participants read short paragraphs that
contained a correct homophone, an incorrect homophone, or a spelling control. Target words were orthographically similar or
dissimilar, and they appeared in context that predicted the target or was neutral with respect to the target. The pattern
of data obtained for skilled readers was consistent with past work (Rayner et al., Journal of Experimental Psychology: Learning, Memory and Cognition 24(2), 476–497, 1998). Skilled readers showed no reading time differences between the correct homophone and the incorrect homophone,
as long as the two were orthographically similar, but reading times on these words were faster than the spelling control condition.
The pattern of data for the adults who were learning to read was different. These readers were actually better at noticing that an incorrect version of the homophone was present. Importantly, we did find consistent significant differences
between the incorrect homophone condition and the spelling control condition. This suggests the adults who were learning to
read use phonological codes during word recognition, but they do so less efficiently than skilled readers. 相似文献

Representing written vowels in university students with dyslexia compared with normal hebrew readers
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 purpose of this study was to determine the components of working memory (WM) that underlie less skilled readers' comprehension and word recognition difficulties. Performance of 3 less skilled reading subgroups---children with reading disabilities (RD) in both word recognition and comprehension; children with comprehension deficits only; and children with low verbal IQ, word recognition, and comprehension (poor readers)--was compared to that of skilled readers on WM, short-term memory (STM), processing speed, executive, and phonological processing measures. Ability group comparisons showed that (a) skilled readers outperformed all less skilled readers on measures of WM, updating, and processing speed; (b) children with comprehension deficits only outperformed children with RD on measures of WM, STM, phonological processing, and processing speed; and (c) children with RD outperformed poor readers on WM and phonological processing measures. A hierarchical regression analysis showed that (a) subgroup differences on WM tasks among less skilled readers were moderated by a storage system not specific to phonological skills, and (b) STM and updating contributed significant variance to WM beyond what was contributed by reading group classification. The latter finding suggested that some differences in storage and executive processing emerged between skilled and less skilled readers that were not specific to reading. 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

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

Two groups of undergraduate students, matched for reading skill but differing in spelling ability, participated in three experiments with the aim of exploring the causes of differences in spelling skill in this population. In the first experiment participants were presented with a range of tasks to investigate the possibility that the poor spellers had poorer phonological abilities than the good spellers. No significant differences were observed. In Experiment 2, a lexical decision task was used. The words in the task differed in orthographic neighbourhood size (N) and frequency. Analysis of the latencies revealed effects of frequency and N, but the effect of spelling group was not significant and neither was the interaction with N. Analysis of the errors revealed that the poor spellers made significantly more errors than the good spellers. In Experiment 3 participants were asked to identify the letters in briefly presented words and non‐words. There was a significant effect of stimulus type in favour of words. Poor spellers made more errors in the task than the good spellers, although the difference was restricted to non‐words. Finally, an analysis of the errors made in spelling to dictation by the two groups was carried out. This revealed that the poor spellers were more likely than the good spellers to make errors that were not phonologically plausible and that differed markedly from the target. Overall, the results are interpreted in terms of a partial orthographic representations explanation of poor spelling in good readers. 相似文献

Skilled reading involves rapid and automatic word recognition. Through a self‐teaching process, phonological decoding during reading is thought to establish the word‐specific representations in memory that support efficient word reading. Much is known about orthographic learning during reading; less is understood about this process during spelling. Here, we compared the degree of orthographic learning that occurs during reading and spelling. Forty‐eight children in Grade 2 practised reading or spelling nonwords within stories. Orthographic learning was measured using spelling recognition, spelling production and word naming tasks. Both readers and spellers showed evidence of orthographic learning; however, spellers outperformed readers on all tasks. Overall, results suggest that spelling sets up a higher quality representation in memory and highlight the importance of spelling in the development of word reading efficiency. 相似文献

The prevalence of low comprehension among deaf readers has been documented for decades, yet the problem persists. Progress has been hampered by uncertainty regarding which aspects of reading competence ought to be the primary focus of concerted instructional efforts. This article examines whether temporary storage capacity and/or processing automaticity may explain the difference in comprehension between skilled and less skilled adult deaf readers. Temporary storage capacity is the ability to maintain separate bits of information in current memory while they are being processed. Processing automaticity is the ability to complete certain basic operations of reading, such as recognizing individual words and chunking sets of words into meaningful phrases, with a minimum of intentional mental effort. In this study one group of deaf adults reading at the college level and another reading at the 5th-grade level completed a battery of experimental tasks that generated multiple indicators of storage capacity and automaticity. These included the reading span task of Daneman and Carpenter (1980), an analogous addition span task, two measures of phonological processing, and a sentence-reading task that varied the demands on temporary storage and processing automaticity. Results suggest that skilled readers do not command an exceptionally large temporary storage capacity, nor do less skilled readers suffer from deficient storage capacity. The indicators of processing automaticity suggest, however, that less skilled readers must invest significantly more conscious mental effort than skilled readers to complete basic operations of reading. These findings are applied to theory related to (a) the nature of the breakdowns in comprehension faced by readers with low automaticity, (b) the interaction of low automaticity with other obstacles to comprehension, and (c) the design of practice experiences to increase the automaticity and ultimately the comprehension of deaf readers. 相似文献

The present study tested the hypothesis that underlying orthographic representations vary in completeness within the individual, which is manifested in both spelling accuracy and reading speed. Undergraduate students were trained to improve their spelling of difficult words. Word reading speed was then measured for these same words, allowing for a direct evaluation of whether improvements in spelling would bring about faster reading speeds. Results were clear: Spelling accuracy and reading speed were strongly related across and within participants. Most important, words that improved in spelling accuracy were read more rapidly at posttest than words that did not show improvement in spelling. These results provide direct evidence showing that the quality of orthographic representations, as indexed by spelling accuracy, directly relates to reading speed. This is consistent with the lexical quality hypothesis and highlights the relevance of spelling in literacy acquisition. 相似文献

The current study examined the predictive roles of L2 vocabulary knowledge and L2 word reading skills in explaining individual differences in lexical inferencing in the L2. Participants were 53 Israeli high school students who emigrated from the former Soviet Union, and spoke Russian as an L1 and Hebrew as an L2. L2 vocabulary knowledge and decoding accuracy predicted L2 reading comprehension, which in turn was strongly related to lexical inferencing abilities in the L2. In addition, decoding accuracy predicted additional variance in lexical inferencing, beyond the role of reading comprehension. These findings support the idea that beginning L2 readers with more precise and efficient lexical representations demonstrate better lexical inferencing abilities, most likely due to the increased automatization of word reading, which frees up resources for higher level processing. These results suggest that lexical inferencing from text in the L2 might be limited not only by vocabulary knowledge and higher order comprehension processes, but also by basic decoding skills. 相似文献

Children who are poor readers have difficulty naming pictured objects. Their naming difficulty could be a result of inadequate representations of the phonology of words, inadequate processing of those representations, or both. In this study, third-grade good and poor readers were tested on object naming, and, in cases of naming failure, forced-choice recognition tasks were used to probe their knowledge of the phonology of the object names. The two reading groups showed no differences in their ability to select the initial phonemes or rhymes of object names they had not produced spontaneously. Moreover, initial phoneme prompts were helpful for both reading groups. The children differed, however, in their ability to produce words after being given rhyme information. The results indicated that, except in the ability to manipulate explicitly phonological information, the poor readers; performance was qualitatively similar to that of the good readers. It is suggested that training in phonological analysis may help poor readers overcome the deficiencies in establishing and processing phonological representations that lead to their quantitative deficit in object naming. 相似文献

In this article, we explore the relationship between rapid automatized naming (RAN) and other cognitive processes among below-average, average, and above-average readers and spellers. Nonsense word reading, phonological awareness, RAN, automaticity of balance, speech perception, and verbal short-term and working memory were measured. Factor analysis revealed a 3-component structure. The first component included phonological processing tasks, RAN, and motor balance. The second component included verbal short-term and working memory tasks. Speech perception loaded strongly as a third component, associated negatively with RAN. The phonological processing tests correlated most strongly with reading ability and uniquely discriminated average from below- and above-average readers in terms of word reading, reading comprehension, and spelling. On word reading, comprehension, and spelling, RAN discriminated only the below-average group from the average performers. Verbal memory, as assessed by word list recall, additionally discriminated the below-average group from the average group on spelling performance. Motor balance and speech perception did not discriminate average from above- or below-average performers. In regression analyses, phonological processing measures predicted word reading and comprehension, and both phonological processing and RAN predicted spelling. 相似文献

This paper advances the argument that in learning to read/spell Chinese characters and words, it is important for learners
to understand the role of the component parts. These constituents consist of phonetic and semantic radicals, or bujians, made
up of clusters of strokes in their proper sequence. Beginning readers/spellers need to be sensitive to the positional hierarchy
and internal structure of these constituent parts. Those Chinese children diagnosed with developmental dyslexia tend to have
more difficulties in spelling Chinese characters and in writing to dictation than in reading. A lexical decision study with
two groups of tertiary students differing in their Chinese language ability was carried out to test their efficiency in processing
real and pseudo characters as a function of printed frequency of the characters, and the consistency of their component semantic
radicals. There is some evidence that even for adult readers differing in their Chinese language ability, lexicality, frequency
of characters and the consistency of the semantic radicals affect accurate and rapid character identification. Suggestions
for research and teaching approaches are made to enhance the analysis and synthesis of the phonetic and semantic radicals
to promote efficient reading and spelling in Chinese. 相似文献
