Verbal short-term memory deficits are a common characteristic of children with reading problems and may markedly increase
the difficulty of learning to read. Previous work suggests that the basis of the short-term memory deficit may involve limitations
in phonetic coding. In the present paper, a series of experiments are reviewed which examined the role of phonological processes
in short-term memory. First, a developmental study is described in which a significant relationship was found between phonetic
processes and verbal memory span, but not between phonetic processes and nonverbal memory. Second, additional studies are
reviewed which collectively found that children with reading problems are less accurate at phonetic encoding than are good
readers, and that performance on phonetic processing corresponds with verbal memory span. No reading group differences were
obtained on nonverbal perception or memory tasks. These findings suggest that both developmental and individual differences
in verbal memory span are related to the efficiency of phonological processes. Practical implications of current cognitive
research are discussed.

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

The purpose of this study was to determine whether children with dyslexia, that is, children whose reading levels were significantly lower than would be predicted by their IQ scores, constituted a distinctive group when compared with poor readers, that is, children whose reading scores were consistent with their IQ scores. The performance of children with dyslexia, poor readers, and normally achieving readers was compared on a variety of reading, spelling, phonological processing, language, and memory tasks. Although the children with dyslexia had significantly higher IQ scores than the poor readers, these two groups did not differ in their performance on reading, spelling, phonological processing, or most of the language and memory tasks. In all cases, the performance of both reading disabled groups was significantly below that of nondisabled readers. The findings were similar whether absolute difference or regression scores were used. Reading disabled children, whether or not their reading is significantly below the level predicted by their IQ scores, experience significant problems in phonological processing, short-term and working memory, and syntactic awareness. On the basis of these data, there does not seem to be a need to differentiate between individuals with dyslexia and poor readers. Both of these groups are reading disabled and have deficits in phonological processing, verbal memory, and syntactic awareness. 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

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

Relations between phonological processing and speech perception skills in reading-disabled children and adults are considered. Following Wagner and Torgesen (1987), phonological processing is comprised of at least three distinct though interrelated abilities--phonemic awareness, phonological recoding in lexical access, and short-term verbal memory skills. Speech perception skills may also represent two domains, speech perception and short-term memory. Studies of speech perception and word reading are critiqued. The interactions of speech perception, phonological processing skills, and word-reading abilities with development are considered in a preliminary model of reading. Although studies of phonological processing and speech perception in poor readers have thus far developed separately, experimenters in these isolated domains could benefit from the research findings in each and the unique paradigms each uses to investigate deficits in poor readers. 相似文献

In this study, we explored the relationship between beginning readers' phonological awareness and other aspects of phonological processing, specifically as manifested in short-term memory and comprehension tasks. The theoretical questions underlying the study were (a) what roles phonological processes play in children's beginning reading, from word identification through sentence comprehension, and (b) whether those roles are sufficiently related that potential difficulties at one level directly affect processing at other levels. Phonologically induced effects were observed for word-list memory and for sentence judgments for both novice readers (at the end of kindergarten) and relatively more experienced readers (end of Grades 1 and 2). For both age groups, correlational analyses revealed relationships among phonological awareness, phonological processing in list memory, and word reading. However, phonological processing in sentence comprehension was not related to other types of phonological processing. These results indicate that although phonology plays a role during comprehension, phonological processing may not be as limiting a factor in comprehension as in word reading. 相似文献

This paper investigates the relationship between phonological processing and reading ability amongst grade 4 and grade 5 Arabic
speaking children in Egypt. In addition to measuring reading level, the study assessed the children’s ability to identify
rhymes, delete individual phonemes from words, retain and manipulate sequences of digit names and rapidly access verbal labels.
Further literacy and literacy-related tasks required children to decode novel letter strings, to distinguish similar words,
to identify words within letter chains and to correctly spell dictated text. A non-verbal ability measure was also included
to allow comparisons to be made between a group of poor readers with good non-verbal skills (dyslexics) with a control group
of chronological-age-matched normal readers with equivalent average scores on the non-verbal task. Results indicated relationships
between literacy ability, decoding and phonological processing within this cohort, as well as identifying differences between
dyslexic and control groups that suggest Arabic dyslexics show signs of poor phonological skills. The study supports the view
that Arabic dyslexic children have impairments in the phonological processing domain. 相似文献

Whereas many studies point to a positive relationship between phonological skills and reading in English, little is known about these relationships for children learning to read in a morphemic orthography such as Chinese. The aim of this study was to examine the relationships among reading ability, phonological, semantic and syntactic skills in Chinese. The participants were 196 grade 1 to grade 4 Chinese children in Hong Kong. A word recognition task in Chinese was developed and children who scored in the lowest quartile were classified as poor readers. The children were administered phonological tasks (tone and rhyming discrimination), semantic tasks (choosing similar words and sentences meanings), a syntactic task (oral cloze), and a working memory task. The results showed that word recognition was highly correlated with phonological skills and semantic processing, and was only moderately related to syntactic knowledge and working memory. Poor readers showed a significant lag in the development of these skills with the most significant problems at the phonological and semantic levels. Phonological skills are important to the acquisition of reading skills in both Chinese and English. 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 purpose of this study was to determine whether poor readers have more pronounced problems than average-reading peers reading
derived words the base forms of which undergo a phonological shift when a suffix is added (i.e., shift relations as in “natural”),
as compared to derived words whose forms are phonologically and orthographically transparent (i.e., stable relations, as in
“cultural”). Two computer-based word recognition tasks (Naming and Lexical Decision) were administered to children with reading
disability (RD), peers with average reading ability, and adults. Across tasks, there was an effect for transparency (i.e.,
better performance on stable than shift words) for both child groups and the adults. For the children, a significant interaction
was found between group and word type. Specifically, on the naming task, there was an advantage for the stable words, and
this was most noteworthy for the children with RD. On the lexical decision task, trade-offs of speed and accuracy were evident
for the child reader groups. Performances on the nonwords showed the poor readers to be comparable to the average readers
in distinguishing legal and illegal nonwords; further analyses suggested that poor readers carried out deeper processing of
derived words than their average reading peers. Additional study is needed to explore the relation of orthographic and phonological
processing on poor readers’ memory for and processing of derived words. 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

This study examined the patterns of reading and spelling performance of first-grade Greek children who either were facing difficulties in literacy acquisition or were normal achievers. In addition, we studied the relationship between obtained literacy development levels and the children's phonological awareness and ability to retain phonological information in short-term memory. The participants were tested in the reading of single letters, letter clusters, words, and nonwords, as well as in word and nonword spelling. Furthermore, their phonological processing knowledge was assessed via a battery of phonological awareness tasks and short-term memory phonetic-representation tasks. The main findings of the study were as follows: (a) Accurate decoding of Greek was achieved by almost every young child (attributed mainly to the nature of the Greek writing system); (b) the time the children needed to process a written item was the crucial index of their difficulty in literacy acquisition; (c) spelling was performed by deriving the orthographic form of a word on the basis of sound-spelling correspondence knowledge; (d) although the children with difficulties in literacy development had achieved a satisfactory performance in phonological processing, their performance was nevertheless significantly lower than that of the normal achievers; and (e) phonemic awareness and speech rate tasks were among the best predictors of learning to read and spell Greek words. 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

The present study explores the relationship between basic auditory processing of sound rise time, frequency, duration and
intensity, phonological skills (onset-rime and tone awareness, sound blending, RAN, and phonological memory) and reading disability
in Chinese. A series of psychometric, literacy, phonological, auditory, and character processing tasks were given to 73 native
speakers of Mandarin with an average age of 9.7 years. Twenty-six children had developmental dyslexia, 29 were chronological
age-matched controls (CA controls) and 18 were reading-matched controls (RL controls). Chinese children with dyslexia were
significantly poorer than CA controls in almost all phonological tasks, in semantic radical search, and in phonological recoding
proficiency. Chinese children with dyslexia also showed significant impairments in most of the basic auditory processing tasks.
Regression analyses demonstrated that different auditory measures of rise time discrimination were the strongest predictors
of individual differences in Chinese character reading (1 Rise task) and phonological recoding (2 Rise task) respectively,
with frequency discrimination also important for nonsense syllable decoding. Our results support the hypothesis that accurate
perception of the amplitude envelope of speech is critical for phonological development and consequently reading acquisition
across languages. 相似文献

A 3-group reading-level design was used to investigate phonological analysis, verbal working memory, and pseudoword reading performance in less skilled fourth-grade readers. Children were given phonological oddity tasks assessing their sensitivity to subsyllabic and phonemic units, together with standardized tests of verbal working memory and pseudoword reading. Less skilled fourth-grade readers performed lower than both chronological age and reading-level controls on the phonological oddity and pseudoword reading tests. Less skilled fourth-grade readers performed at the same level as skilled second-grade readers on a test of verbal working memory. Skilled fourth-grade readers scored higher than both other groups on this test. Correlational analyses were consistent with the view that phonological analysis skills contribute more strongly than verbal working memory skills to children's decoding abilities. 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

The rationale for the study was that if dyslexic and garden-variety poor readers differ in reading-related cognitive skills, there is justification for believing dyslexia to be a distinct entity. Subjects were 110 children aged 6 to 10 years, divided into groups of dyslexic poor readers varying in verbal IQ, garden-variety poor readers, and good readers. Findings suggest that there are valid grounds for believing that dyslexia is a separate entity from garden-variety poor reading, and that it is found among children at all verbal IQ levels. Poor phonological awareness and nonword reading, in relation to normal readers, were shared by dyslexic and garden-variety poor readers. Deficits unique to dyslexic poor readers were problems in both automatic visual recognition and phonological recoding of graphic stimuli. The study supports the phonological-core variable-difference model of Stanovich (1988) in that both dyslexic and garden-variety poor readers showed phonological processing deficits, but they were more extensive in dyslexics. 相似文献
