Sixty-eight third graders who were less-skilled readers performed more poorly than younger reading-level control children on tests of pseudoword reading and phonological sensitivity. These findings add to the growing consensus that the proximal cause of reading difficulties are spelling-sound coding problems that result from deficient underlying phonological processes and structures. Analyses of their word and pseudoword reading performance provided some suggestive evidence that less-skilled readers are less sensitive than their younger reading-level matched counterparts to all subword-size orthographic units, perhaps especially to grapheme-sized units. 相似文献

Phonological Analysis Skills, Verbal Working Memory, and Reading Ability in Second-Grade Children 总被引：9，自引：0，他引：9
This study tested the hypothesis that phonological analysis skills make a unique contribution to reading ability against the hypothesis that one latent phonological factor underlies the assocations among analysis skills, verbal working memory skills, and reading achievement. Hierachical multiple regression analyses examined the unique contributions of phonological analysis and verbal working memory measures to the prediction of 3 measures of concurrent reading ability in 68 second-grade children (mean age 7 years 4 months). Phonological analysis and verbal working memory measures each accounted for unique variation in each of the 3 reading measures. In addition, phonological analysis measures, but not verbal working memory measures, were particularly strong predictors of pseudoword reading skills. These results suggest that, although phonological analysis and verbal working memory skills share a substantial amount of common variance, phonological analysis and verbal working memory tasks do tap somewhat different reading-related skills. 相似文献

Although weaknesses in metaphonological skills are well-documented in poor readers, prior studies have yielded inconsistent
findings as to whether less-skilled readers also have deficits in the more primary phonological processes entailed in verbal
working memory and speech production tasks. The present study was designed to examine this issue by comparing less-skilled
third-graders readers (n=30) with younger children at the same reading level (n=30) and with more-skilled agemates (n=30)
on a variety of tasks that require phonological processing (i.e., three “verbal memory” tasks [word span, span with concurrent
processing, pseudoword imitation] and three “speech production” tasks [word-pair repetition, tongue twisters, rapid naming]).
The results were striking: the less-skilled third-grade readers had significantly lower accuracy scores than both their agemates
and the younger normal readers on the word span, pseudoword imitation, word-pair repetition, and tongue twister tasks. Measures
of accuracy were more related to reading ability than were measures of speed. Performance on a pseudoword imitation task was
the variable most strongly linked to reading achievement. 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

Reading,syntactic, and working memory skills of bilingual Portuguese-English Canadian children 总被引：1，自引：0，他引：1
The purpose of the study was to examine the nature of language, memory, and reading skills of bilingual students and to determine the relationship between reading problems in English and reading problems in Portuguese. The study assessed the reading, language, and memory skills of 37 bilingual Portuguese-Canadian children, aged 9–12 years. English was their main instructional language and Portuguese was the language spoken at home. All children attended a Heritage Language Program at school where they were taught to read and write Portuguese. The children were administered word and pseudoword reading, language, and working memory tasks in English and Portuguese. The majority of the children (67%) showed at least average proficiency in both languages. The children who had low reading scores in English also had significantly lower scores on the Portuguese tasks. There was a significant relationship between the acquisition of word and pseudoword reading, working memory, and syntactic awareness skills in the two languages. The Portuguese-Canadian children who were normally achieving readers did not differ from a comparison group of monolingual English speaking normally achieving readers except that the bilingual children had significantly lower scores on the English syntactic awareness task. The bilingual reading disabled children had similar scores to the monolingual reading disabled children on word reading and working memory but lower scores on the syntactic awareness task. However, the bilingual reading disabled children had significantlyhigher scores than the monolingual English speaking reading disabled children on the English pseudoword reading test and the English spelling task, perhaps reflecting a positive transfer from the more regular grapheme phoneme conversion rules of Portuguese. In this case, bilingualism does not appear to have negative consequences for the development of reading skills. In both English and Portuguese, reading difficulties appear to be strongly related to deficits in phonological processing. 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

The purpose of this study was to assess the contributions of specific components of verbal and nonverbal working memory and of phonological awareness to the prediction of reading achievement. One hundred and three children from grades 1, 2, and 3 were administered a measure of phonological awareness, four measures of working memory, four measures of academic achievement, and a measure of verbal intelligence. Separate multiple regression analyses controlling for the effects of age, sex and verbal intelligence showed that tests of verbal memory and of direct recall significantly predicted reading and spelling achievement whereas tests of backward recall significantly predicted only pseudoword identification. Phonological awareness was also found to relate significantly to reading and spelling achievement even when working memory was partialled out. Thus, phonological awareness and measures of working memory predicted specific and significant amounts of variance in reading and spelling achievement. Further, none of these measures were specifically related to arithmetic achievement. The specific roles of phonological awareness and working memory in reading development are examined in the discussion. 相似文献

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical
items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate
the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth graders, extreme groups
of good and poor readers were identified and compared on measures of receptive vocabulary, expressive naming, acceptability
judgments for variants of object names, imitation and correction of naming errors by another speaker, pseudoword repetition,
and long-term memory. Performance was generally better by older than younger students and by good than poor readers at each
age, with little interaction between grade and reader group. The results indicated that for both good and poor readers, imprecise
phonological knowledge, especially about long words, contributed to children’s difficulties on all naming tasks. Memory differences,
however, appeared to play only a minor role in explaining the strong association between naming and reading. 相似文献

Dyslexia and the double deficit hypothesis 总被引：1，自引：4，他引：1

The double deficit hypothesis (Bowers and Wolf 1993) maintains that children with both phonological and naming-speed deficits
will be poorer readers than children with just one or neither of these deficits. In the present study, we drew on this hypothesis
to help understand why some children have a serious reading impairment. In addition, by adding an orthographic factor, we
extended it to a triple deficit hypothesis. Participants were 90 children aged 6 to 10 years. Dyslexic children, whose reading
was low for age and for expected level, garden-variety poor readers, reading-level matched younger children, and low verbal
IQ good readers, were compared. The dyslexic group was significantly lower then the garden-variety poor readers and the low
verbal IQ good readers on most measures, and lower than the younger group on phonological measures. Findings support the double
deficit hypothesis of Bowers and Wolf, and also the triple deficit hypothesis. Most of the poorest readers, nearly all of
whom qualified as dyslexic, had a double or triple deficit in phonological, naming-speed, and orthographic skills. Conclusions
were that dyslexia results from an overload of deficits in skills related to reading, for which the child cannot easily compensate. 相似文献

This study investigated qualitative differences in poor readers relative to normally achieving readers of the same reading level. Thirty-eight 9-year-old poor readers and forty 7- and 8-year-old reading-age-matched normally achieving readers from the United Kingdom were matched in phonemic processing and then given tests of memory span and visual discrimination of letter-like characters, were required to read different word types (regular, exception, and pseudoword), and were asked to complete a homophonic pseudoword test. The poor readers were worse at reading pseudowords compared to the controls, but this difference was unrelated to phonemic length of number of letters, or to the ease of producing analogies for the pseudowords. The results suggest that although there are no differences with reading-age controls in phonological processing, poor readers have worse grapheme-phoneme conversion skills and greater reluctance to relinquish the lexical route when appropriate. The results also showed that poor readers were slightly better at visual discrimination but had poorer memory spans. 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

The present study examined factors that influence the process of learning to read in a second language. The Hebrew reading
comprehension skills of 68 Russian-speaking children (mean age 7 years 6 months) were screened at the start of Grade 2. From
this sample, 40 participants were selected: 20 successful learners and 20 unsuccessful learners. These two groups were then
tested on a wide range of language skills (e.g., phonological processing, vocabulary, syntactic and morphological awareness)
in both languages (Hebrew and Russian) and reading skills in Hebrew (e.g., reading speed and accuracy).
Two factors, level of spoken Hebrew and phonological awareness deficits in both languages, were significant. Phonological
awareness difficulties constituted the key factor associated with poor decoding whereas insufficient mastery of spoken Hebrew
was important in the case of reading comprehension. An interesting dissociation was also found in our poor readers between
impaired phonological awareness and other unimpaired phonological processing abilities such as oral pseudoword repetition
and working memory. These findings suggest that, in addition to poor spoken L2 proficiency, poor readers are characterized
more by a metalinguistic rather than a linguistic deficit in their native tongue. 相似文献

Ninety-six children were administered an orthographic test as preschoolers and two measures of nonphonemic phonological awareness
(syllable segmentation, rhyme detection) in midkindergarten. The power of the three measures to predict reading at grades
1, 3, and 7 was examined. With earlier reading level, preschool verbal IQ and age, and verbal memory controlled, both phonological
measures added significant variance to grade 1 word reading, and syllable segmentation also contributed to reading comprehension,
but neither measure accounted for variance in reading at grades 3 and 7. The orthographic measure contributed significant
variance to grade 1 word reading, and also to reading vocabulary and reading comprehension at grades 3 and 7, with the proportion
of variance in reading comprehension increasing with grade level. When early (grade 1) and late (grade 7) poor readers were
compared, late poor readers were significantly higher than early poor readers on a first grade phonological test, but significantly
lower on a seventh grade orthographic measure. Evidence suggested that a late reading comprehension deficit may be due to
poor orthographic processing skills in some children, but to a phonological and general verbal deficit in others. 相似文献

The difficulties experienced by below-average readers in phonological decoding tasks are well documented. Recent research has suggested that additional deficits in perceptual-motor fluency, handedness, and memory may also exist among below-average readers. To evaluate these claims, average and below-average readers and spellers were compared on a range of phonological processing, verbal short-term and working memory, rapid naming, handedness, and perceptual-motor fluency tasks. Average and below-average readers were sampled in a comparable manner and were also comparable on age, gender, nonverbal ability, socioeconomic status, and ethnicity. Below-average readers and spellers performed lower than average readers and spellers on rhyme detection, pseudoword decoding, and rapid digit (but not picture) naming tasks, but showed no differences in handedness tasks or on a range of other perceptual-motor tasks. 相似文献

The dissociation between phonological and orthographic processes in word reading was investigated in a study involving 147 children in grade 3. The criterion measure was a timed word reading test. Two tasks assessed phonological skills and two tasks assessed orthographical skills. Orthographic ability accounted for variance in word reading even after phonological ability had been controlled. Poor readers differed from skilled readers in the way phonological and orthographic factors were balanced. The relationship between the two factors was fairly strong among poor readers, whereas the correlation was low for more skilled readers. Furthermore, phonological factors played a much stronger role in explaining the variance in word reading among poor readers, while on the other hand, orthographic factors were more powerful among skilled readers. 相似文献

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students. 相似文献

Metalinguistic and literacy abilities were studied in twenty-seven nonvocal cerebral palsied school children. The participants of the study were presented four tests of phonological awareness: rhyme recognition, sound identification, phoneme synthesis and word length analysis. Their verbal comprehension was measured using a semantic and a syntactic task. Two tests of nonverbal memory: the visual sequential task from ITPA and Corsi blocks and the Digit Span task from WISC, were also included. These measures were related to their reading and spelling ability. The nonvocal children performed on a lower level on the reading and spelling tasks than did the children of two comparison groups, one matched for mental age and one for mental and chronological age. There were no differences in phonological awareness or in verbal memory. The disabled children performed worse on the verbal comprehension task than the children in the comparison groups. Although the reading and spelling results were low in the nonvocal group there were children showing some literacy skills. A within-group analysis performed in the nonvocal group showed that the reading children performed better on all memory tests, and on the sound identification and the word length analysis tasks than the nonreading ones. They also showed better results on verbal comprehension, the semantic task and used more symbols in their communication. Synthetic speech was more often used in reading and spelling education in the reading subgroup than in the nonreading. Metalinguistic abilities and possibility of acoustic rehearsal are discussed as important factors in reading and spelling acquisition in the nonvocal population. 相似文献

The double-deficit hypothesis acknowledges both phonological processing deficits and serial naming speed deficits as two dimensions associated with reading disabilities. The purpose of this study was to examine these two dimensions of reading as they were related to the reading skills of 29 Spanish average readers and poor readers (mean age 9 years 7 months) who met the criteria for either single phonological deficit (PD), double deficit (DD), or no deficit. DD children were the slowest readers and had the weakest orthography processing skills. No significant differences were found between PD and DD groups on word and pseudoword reading. Word reading and reading comprehension skills were average or above average in the three studied groups. As in previous studies in transparent orthographies, word reading was not a salient problem for Spanish poor readers, whereas for the DD group, reading speed and orthographic recognition skills were significantly affected. 相似文献
