The contributions of naming speed measured on both serial-list and various discrete-trial formats to several reading subskills were examined longitudinally to determine their impact independent of other reading-related skills on reading disabilities. Tests of symbol naming speed, phonological awareness, vocabulary, memory span and coding speed were given to 38 poor and average readers when they were in Grades 2, 3 and 4. Grade 4 poor readers were discriminated from moderately poor or good readers on serial-list and discrete-trial naming speed tests in all grades. In addition, phonological awareness and vocabulary, but not memory span or coding speed, discriminated groups. These variables in Grade 2 contributed unique variance to reading scores in Grade 4 in differing patterns. Hypotheses about the nature of the reading — naming speed relationship are discussed.  相似文献

The associations of multiple measures of speeded naming, phonological awareness, and verbal intelligence with word reading were examined in 51 poor readers and 74 good readers in third and fourth grade. Structural equation modeling was used to determine the extent to which these two groups exhibited structurally invariant patterns of associations among the constructs. Results revealed that for poor readers, both speeded naming and phonological awarencess were significantly associated with word reading, but verbal intelligence had no association with it. In contrast, for good readers, phonological awareness and verbal intelligence were significantly associated with word reading, but naming speed was not. Findings are discussed in light of the double deficit hypothesis.  相似文献

This study investigated the role of speed of processing, rapid naming, and phonological awareness in reading achievement. Measures of response time in motor, visual, lexical, grammatical, and phonological tasks were administered to 279 children in third grade. Measures of rapid object naming, phonological awareness, and reading achievement were given in second and fourth grades. Reading group comparisons indicated that poor readers were proportionally slower than good readers across response time measures and on the rapid object naming task. These results suggest that some poor readers have a general deficit in speed of processing and that their problems in rapid object naming are in part a reflection of this deficit. Hierarchical regression analyses further showed that when considered along with IQ and phonological awareness, speed of processing explained unique variance in reading achievement. This finding suggests that a speed of processing deficit may be an "extraphonological" factor in some reading disabilities.  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

This study examined the interaction between speech perception and sentential context among 13 poor readers and 49 good readers in grades one to three. Children's performance was examined on tasks assessing expressive and receptive vocabulary, reading skill, phonological awareness, pseudoword repetition, and phoneme identification. Good readers showed clearly defined categorical perception in the phoneme identification task for both sentence frames biased to the identification of the /b/ or /p/ phoneme. The /b/–/p/ category boundary for the BATH frame was at longer voice onset times (VOTs) than the boundary for PATH frame. Poor readers showed less sharply defined categorical perception with both sentence frames. Although poor readers did not show a shift in the /b/–/p/ category boundary, sentential context did affect the overall rate with which phonemes were identified as /b/ or /p/ at each VOT. These findings suggest that semantic information may operate as a compensatory mechanism for resolving ambiguities in speech perception. Furthermore, expressive vocabulary was more closely related than receptive vocabulary to individual differences in reading and phonological processing, providing support for the phonological distinctness hypothesis.  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

The main aim of the study was to determine whether performance on reading-related cognitive processing tasks would help predict reading progress in children receiving special help. The 86 subjects were initially aged six to eight years and most were followed up after two years. When variance due to IQ and age was accounted for, an orthographic processing task, phonological awareness (phoneme deletion), and digit- naming speed were significant predictors of later reading skills. A strength in phonological awareness differentiated initial poor readers who later made excellent gains in reading from poor readers who did not improve. Children whose reading deteriorated had serious weaknesses on tasks of naming speed and confrontation naming. Their poor lexical retrieval skills had a more deleterious effect on later reading than on initial. Indications were that for children diagnosed as poor readers at age six or seven years, prognosis is better for boys, and for garden- variety poor readers, than for dyslexics. Caution was urged in applying the term dyslexic to children in the first two school grades because many of them will be slow starters who do not have a persistent reading problem.  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

The present study was designed to examine the question of whether developmental dyslexia in 12-year-old students at the beginning of secondary education in the Netherlands is confined to problems in the domain of reading and spelling or also is related to difficulties in other areas. In particular, hypotheses derived from theories on phonological processing, rapid automatized naming, working memory, and automatization of skills were tested. To overcome the definition and selection problems of many previous studies, we included in our study all students in the first year of secondary special education in a Dutch school district. Participants were classified as either dyslexic, garden-variety, or hyperlexic poor readers, according to the degree of discrepancy between their word recognition and listening comprehension scores. In addition, groups of normal readers were formed, matching the poor readers in either reading age or chronological age. A large test battery was administered to each student, including phonological, naming, working memory, speed of processing, and motor tests. The findings indicate that dyslexia is associated with deficits in (1) phonological recoding, word recognition (both in their native Dutch and in English as a second language), and spelling skills; and (2) naming speed for letters and digits. Dyslexia was not associated with deficits in other areas. The results suggest that developmental dyslexia, at the age of 12, might be (or might have become) a difficulty rather isolated from deficiencies in other cognitive and motor 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

Because of the research demonstrating the roles of phonological awareness, serial naming speed, and orthographic processing in reading, a test of each of these skills was added to a preschool screening battery. The main aim of the study was to determine whether these measures would contribute to the prediction of reading. The 118 subjects were first tested six months before kindergarten entry and were followed up 19 and 24 months later. Each additional screening test made a significant, independent contribution to the prediction of early first grade word reading/spelling, after the contributions of a parent rating of preschool reading ability (PRA), verbal IQ, socio-economic status (SES), and chronological age were accounted for. With letter naming and PRA, the additional tests were responsible for 62 percent of the variance. The orthographic test made the largest single contribution (32%) to the variance in word reading/spelling. Variables contributing significantly to the prediction of later first grade reading comprehension were (in order of proportion of the variance accounted for) letter naming, sentence memory, object naming speed, the orthographic test, and SES. The revised preschool screening battery correctly identified 91 percent of individual first grade good and poor readers. It was concluded that preschool measures of phonological awareness, serial naming speed, and orthographic processing make a strong contribution to prediction of first grade reading.  相似文献

Phonological processing, language comprehension, and reading ability   总被引:2,自引:0,他引:2  
Previous research has indicated a relationship between reading ability and the integrity of certain phonological processing skills--skills that operate on the sound structure of language. This study shows how the deficient phonological processing skills of poor beginning readers can impair their comprehension of spoken phrases and sentences that are disambiguated by prosodic cues (i.e., pitch, stress, and pause). Following a brief summary of the available research literature, two new experiments are reported to illustrate that poor readers do not interpret certain sentences as accurately as good readers do, because they are less able to hold phonological material temporarily in working memory. Further insight into the basis of these differences between good and poor readers is provided by two additional pieces of evidence: The differences between good and poor readers are analogous to those between older and younger children readers, and the performance of poor readers tends to resemble that of younger children reading at their same level (i.e., reading-ability-matched controls). Apparently, good and poor readers tend to differ in the rate at which they develop phonological processing skills.  相似文献

The aim of the current study was to further explore the connection between verbal short-term recall and phonological processing for two purposes: (a) To investigate the basis of short-term memory deficits for children with reading disability, and (b) To further explore the origin of developmental verbal memory span increases.Using a variety of memory and phonological tasks, reading group comparisons were conducted testing third-grade good readers and poor readers, and developmental changes were studied with pre-kindergarten, first-grade and third-grade children. The main finding was that a strong relationship was observed between efficiency of phonological processes and capacity of verbal memory supporting the hypothesis that reducing phonological processing requirements in verbal short-term memory increases available resources for storage. No such relationship was found between phonological processing and nonverbal memory. This conclusion was supported by two findings: (a) The verbal short-term memory deficits in poor readers significantly correspond with less accurate phonological processing, and (b) Developmental increases in verbal STM are accompanied by more accurate and rapid execution of phonological tasks.  相似文献

Predictors of early word reading are well established. However, it is unclear if these predictors hold for readers across a range of word reading abilities. This study used quantile regression to investigate predictive relationships at different points in the distribution of word reading. Quantile regression analyses used preschool and kindergarten measures of letter knowledge, phonological awareness, rapid automatised naming, sentence repetition, vocabulary and mother's education to predict first‐grade word reading. Predictors generally varied in significance across levels of word reading. Notably, rapid automatised naming was a significant unique predictor for average and good readers but not poor readers. Letter knowledge was generally a stronger unique predictor for poor and average readers than good readers. Well‐known word reading predictors varied in significance at different points along the word reading distribution. Results have implications for early identification and statistical analyses of reading‐related outcomes. What is already known about this topic
  • Early predictors of word reading are well established, with letter knowledge, phonological awareness and rapid automatised naming identified as key predictors.
  • These relationships are primarily investigated in average readers, or in groups of good and poor readers separated by an arbitrary cut‐off score.
What this paper adds
  • In this study, we used quantile regression to determine significant predictors of word reading across a range of word reading abilities.
  • The quantile regression approach avoids the loss of power that can arise when creating subgroups and has none of the issues associated with the use of a single, arbitrary cut-off score to separate good and poor readers.
  • Letter knowledge and phonological awareness were significantly predictive of word reading across the distribution of word reading abilities, whereas rapid automatised naming was significant only for good readers, and sentence recall was significant only for poor readers.
Implications for theory, policy and practice
  • Results reinforce the usefulness of measures such as letter knowledge, phonological awareness and sentence repetition in the early identification of children at risk for reading disabilities.
  • Results also suggest that measures of rapid naming may add little unique information in differentiating between children who subsequently read in the below‐average range.

The aim of this study was to determine if phonological processing deficits in specific reading disability (SRD) and specific language impairment (SLI) are the same or different. In four separate analyses, a different combination of reading and spoken language measures was used to divide 73 children into three subgroups: poor readers with average spoken language (SRD), poor readers with poor spoken language (SRD + SLI) and average readers with poor spoken language (SLI). These groups were compared on five phonological processing measures. The SRD group had deficits in neural representations of phonemes, phoneme discrimination, phoneme awareness and rapid naming. The SRD + SLI group had more severe deficits than the SRD group on half of these measures, as well as phonological short‐term memory. Children with SLI were free from phonological processing deficits. Thus, phonological processing deficits were the same or different in SRD and SLI, depending on how SRD and SLI were defined, and how phonological processing was measured.  相似文献

This study examined the associations of phonological processing skills with reading and arithmetic ability in Chinese kindergartners (Mage = 5.56 years), third graders (Mage = 9.72 years), and fifth graders (Mage = 11.75 years) (N = 413) of Han descent. The results showed that phonological awareness and rapid automatized naming (RAN) showed stronger relations than phonological memory with reading and arithmetic across grades. Furthermore, the associations of phonological awareness and RAN with reading were much stronger in kindergartners than in primary school children, whereas their relationships with arithmetic remained stable across grades. Among phonological skills, phonological awareness has a unique influence on arithmetic that is independent of Chinese character reading in third-graders and kindergartners. In contrast, RAN uniquely explained the variation in arithmetic skills in fifth graders when reading was statistically controlled for. These findings have important implications for understanding the co-development of reading and arithmetic across grades and raise the possibility of training in phonological awareness and/or RAN to help children at risk for learning disabilities.  相似文献

We examined the nature of and factors related to adolescents’ reading difficulties in a highly transparent orthography. We compared word, pseudoword, and text reading speed and accuracy, rapid naming (RAN) and phonological processing between poor readers (n?=?80) and normally developing readers (n?=?189). Reading problems were manifested in reading speed and in timed pseudoword reading accuracy. RAN predicted speed, and phonological processing predicted accuracy of reading in both groups. Among poor readers, RAN also explained reading accuracy. For the normally developing sample, phonological processing also predicted reading speed.  相似文献

This study examined phonological awareness at the level of phonemes and rhyme and related this to nonword naming ability. Poor readers were compared with 11 year old chronological-age controls and 8 year old reading-age controls. The poor reader group was impaired for chronological age in all tasks, and impaired for reading age at nonword naming and phoneme deletion. The poor readers' rhyming skills, however, were commensurate with reading age. Individual variation was observed together with exceptions to the group findings; most poor readers performed within the range of the reading-age controls on the phonological tasks and in nonword naming. Dissociations in phonological skills were evident, including indications that intact awareness of rhyme may not be a prerequisite for the development of phoneme awareness. Furthermore, phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Therefore, phoneme awareness may be more important than rhyming skill in understanding reading disorders.  相似文献

This study examined the extent to which mora deletion (phonological analysis), nonword repetition (phonological memory), rapid automatized naming (RAN), and visual search abilities predict reading in Japanese kindergartners and first graders. Analogous abilities have been identified as important predictors of reading skills in alphabetic languages like English. In contrast to English, which is based on grapheme-phoneme relationships, the primary components of Japanese orthography are two syllabaries—hiragana and katakana (collectively termed “kana”)—and a system of morphosyllabic symbols (kanji). Three RAN tasks (numbers, objects, syllabary symbols [hiragana]) were used with kindergartners, with an additional kanji RAN task included for first graders. Reading measures included accuracy and speed of passage reading for kindergartners and first graders, and reading comprehension for first graders. In kindergartners, hiragana RAN and number RAN were the only significant predictors of reading accuracy and speed. In first graders, kanji RAN and hiragana RAN predicted reading speed, whereas accuracy was predicted by mora deletion. Reading comprehension was predicted by kanji RAN, mora deletion, and nonword repetition. Although number RAN did not contribute unique variance to any reading measure, it correlated highly with kanji RAN. Implications of these findings for research and practice are discussed.  相似文献
