The current investigation explored the diagnostic utility of reading fluency measures in the identification of children with
reading disabilities. Participants were 50 children referred to a university-based clinic because of suspected reading problems
and/or a prior diagnosis of dyslexia, where children completed a battery of standardized intellectual, reading achievement,
and processing measures. Within this clinical sample, a group of children were identified that exhibited specific deficits
in their reading fluency skills with concurrent deficits in rapid naming speed and reading comprehension. This group of children
would not have been identified as having a reading disability according to assessment of single word reading skills alone,
suggesting that it is essential to assess reading fluency in addition to word reading because failure to do so may result
in the under-identification of children with reading disabilities. 相似文献

The risk for internalizing disorders in children with learning disabilities is frequently debated in the research community
and empirical responses are equivocal. For educators and clinicians, the frequent assumption is that children with dyslexia
also have at least subtle emotional problems. In this study, school-age children with reading problems and their siblings
(N=79) were referred for neuropsychological evaluation. As part of the assessment process, parents, teachers, and the child
were asked to rate the child’s level of internalizing symptoms on several behavior rating scales. Results from analyses of
the data, using both discrepancy and reading cut scores for diagnosis of dyslexia, suggest that children with dyslexia are
not at elevated risk for behaviors related to anxiety, depression, and somatization. Additionally, children at the lowest
end of the reading distribution were no more likely to have significant internalizing symptoms than children with less impaired
reading. 相似文献

This article examines working memory functioning in children with specific developmental disorders of scholastic skills as defined by ICD-10. Ninety-seven second to fourth graders with a minimum IQ of 80 are compared using a 2 x 2 factorial (dyscalculia vs. no dyscalculia; dyslexia vs. no dyslexia) design. An extensive test battery assesses the three subcomponents of working memory described by Baddeley (1986): phonological loop, visual-spatial sketchpad, and central executive. Children with dyscalculia show deficits in visual-spatial memory; children with dyslexia show deficits in phonological and central executive functioning. When controlling for the influence of the phonological loop on the performance of the central executive, however, the effect is no longer significant. Although children with both reading and arithmetic disorders are consistently outperformed by all other groups, there is no significant interaction between the factors dyscalculia and dyslexia. 相似文献

This article addresses the problem of what constitutes effective remediation for developmental dyslexia, combining neuropsychological and applied cognitive perspectives on specific reading disability. Despite its high prevalence, whether the disorder is amenable to treatment and what constitutes effective treatment were questions which, until recently, remained essentially unaddressed by properly controlled evaluation studies. Positive results from controlled remediation studies and experimental training paradigms with disabled and poor reader samples are reviewed. As part of a clinical research program at The Hospital For Sick Children in Toronto, we have completed a series of treatment outcome studies with dyslexic samples (cumulative N = 285) in which we evaluated the efficacy of different programs designed to remediate the reading and reading-related deficits of dyslexic children and adolescents. Results from one of these studies are summarized to illustrate the unique perspective afforded through remedial outcome data: Emphasis is placed on what the results of such studies may reveal of dyslexic learning disabilities. 相似文献

We examined Nonsense-Passage oral reading in adults, using data derived from new and previously published studies (Finucci et al 1976, Gross-Glenn et al 1985). Time-scores and error-frequency data are presented for five samples of non-dyslexic readers with a minimum of a high-school education and no childhood history of dyslexia (N=127). Considerable uniformity is demonstrated across these samples, and reading performance of non-dyslexic individuals contrasts sharply with that observed in four samples of adult familial dyslexics. Both affected and compensated-affected dyslexic subjects read the passages significantly more slowly and with more errors than did nondyslexic readers. Results are discussed in relation to the cognitive and neural processes that may underlie this specific reading difficulty in dyslexics. We have found Nonsense-Passage reading to be especially useful in family studies of inherited dyslexia as a means of quantifying oral reading deficits in adults who have learned to compensate for their children reading difficulties. 相似文献

The present study used the tip-of-the-tongue (TOT) experimental paradigm in a picture naming task to explore the source of the naming deficits of children with dyslexia. Compared with a control group of typically developing readers, the children with dyslexia showed fewer correct responses and spontaneous recalls, more don't know (DK) and TOT responses, and less accurate feeling of knowing (FOK) judgments. When they failed to retrieve a target word, the children with dyslexia did not differ from the control group in the partial semantic information they provided, but they gave less valid and more invalid partial phonological information. The children with dyslexia also benefited less from phonological cues. The phonologically related responses of the children with dyslexia elicited during the administration of the TOT procedure were related to their performance on a phonological awareness test. These findings suggest that the naming problems of children with dyslexia arise because of their difficulty in accessing the phonological word forms after the corresponding abstract lexical representation has been successfully accessed. The results are discussed in relation to the claim that two-stage models of naming can be profitably used in the early identification and treatment of reading disabilities. 相似文献

Research demonstrates that phonological skills provide the basis of reading acquisition and are a primary processing deficit in dyslexia. This consensus has led to the development of effective methods of reading intervention. However, a single phonological deficit is not sufficient to account for the heterogeneity of individuals with dyslexia, and recent research provides evidence that supports a multiple-deficit model of reading disorders. Two studies are presented that investigate (1) the prevalence of phonological and cognitive processing deficit profiles in children with significant reading disability and (2) the effects of those same phonological and cognitive processing skills on reading development in a sample of children that received treatment for dyslexia. The results are discussed in the context of implications for identification and an intervention approach that accommodates multiple deficits within a comprehensive skills-based reading program. 相似文献

There is a growing body of evidence that children with dyslexia have problems not just in reading but in a range of skills
including several unrelated to reading. In an attempt to compare the severity and incidence of deficits across these varied
domains, children with dyslexia (mean ages 8, 12, and 16 years), and control groups of normally achieving children matched
for IQ and for age or reading age, were tested on a range of primitive (basic) skills. The children with dyslexia performed
significantly worse than the same-age controls on most tasks, and significantly worse even than the reading-age controls on
phoneme segmentation, picture naming speed, word tachistoscopic word recognition, speeded bead threading and some balance
tasks. The overall performance of the children with dyslexia is interpreted as showing less complete automatization than normal. 相似文献

The historical roots of the IQ-achievement discrepancy definition of learning disability are discussed as a reference point
for explaining why this definition came into being and why it is inadequate for dealing with the variety of learning and developmental
disabilities that present in school settings. A proposal is offered and justified for defining learning disabilities on the
basis of profiles for multiple developmental domains that affect learning. In this proposal, developmental dyslexia is differentiated
from other learning disabilities. Developmental dyslexia is defined as uneven development (dissociation) between word reading
and higher-level processes in the functional reading system. Dyslexics may struggle with word reading because of deficits
in phonological processes, orthographic-phonological connections, and/or fluency (rate, automaticity, or executive coordination).
The need for both national and international classification schemes for defining specific learning and developmental disabilities
for the purposes of educational services and research is emphasized.

The effects of a Dutch intervention program for dyslexia are reported. The program was individually tailored, depending on the style of reading, the phase of the learning process, and the intermediate results of the treatment. Two groups of participants were involved: (a) a group of children with pure dyslexia (n = 109) and (b) a group that had reading problems but also suffered from cognitive deficits or psychiatric symptoms (n = 29). Scores of reading single words and text at intake and after the intervention were analyzed to assess the efficacy of the intervention program. Furthermore, the effects of pre-intervention variables such as intelligence, reported speech, and language problems and of intervention variables such as the initial level of performance and the duration of the treatment were examined. Both groups benefitted from the intervention, but the children with pure dyslexia profited most. Neither of the groups could catch up the reading deficit. Intelligence and reported speech and language problems did not affect the treatment outcomes. Individual differences in treatment outcome were related to the absolute level of word reading and age at intake. In the group with comorbidity, the intervention program was more successful in relatively younger children. Within this group, the cognitive deficits and types of psychiatric problems were not related to the treatment. 相似文献

This study was designed to assess whether the effects of computer-assisted practice on visual word recognition differed for children with reading disabilities (RD) with or without aptitude-achievement discrepancy. A sample of 73 Spanish children with low reading performance was selected using the discrepancy method, based on a standard score comparison (i.e., the difference between IQ and achievement standard scores). The sample was classified into three groups: (1) a group of 14 children with dyslexia (age M = 103.85 months; SD = 8.45) who received computer-based reading practice; (2) a group of 31 "garden-variety" (GV) poor readers (age M = 107.06 months; SD = 6.75) who received the same type of instruction; and (3) a group of 28 children with low reading performance (age M = 103.33 months; SD = 9.04) who did not receive computer-assisted practice. Children were pre- and posttested in word recognition, reading comprehension, phonological awareness, and visual and phonological tasks. The results indicated that both computer-assisted intervention groups showed improved word recognition compared to the control group. Nevertheless, children with dyslexia had more difficulties than GV poor readers during computer-based word reading under conditions that required extensive phonological computation, because their performance was more affected by low-frequency words and long words. In conclusion, we did not find empirical evidence in favor of the IQ-achievement discrepancy definition of reading disability, because IQ did not differentially predict treatment outcomes. 相似文献

A deficiency in temporal pattern discrimination frequently is a distinguishing characteristic of children with dyslexia or learning disabilities (LD). We studied the feasibility of using the Seashore Rhythm Test, a subtest of the Halstead-Reitan neurological assessment battery (Halstead, 1947), with young children to discriminate children with reading impairments from age-matched controls reading at a normal level, in an effort to develop tools to determine readiness to read in young school-age children. Major considerations in test selection were ease of administration and wide use and acceptance. Fifty-nine children in Grades 1 through 3 were administered a battery of tests during the last 3 weeks of the school year by blinded experimenters. Tests administered included the Seashore Rhythm Test, Benton Visual Retention Test, Peabody Picture Vocabulary Test, Blau Torque Test, and the Rod and Frame Test. Children with reading impairments (n = 24) in all age groups were found to exhibit a marked deficit in the ability to discriminate patterned pairs of tones on the Seashore Rhythm Test compared to controls (n = 26). These children also exhibited deficits in right-left orientation, as indicated by their poor performance on the Blau Torque Test. Performance on the Seashore and the Blau by a group of children diagnosed as learning disabled (n = 9) was similar to the group with reading impairments. No significant differences between controls and children with reading impairments or LD were observed in Rod and Frame or Benton performance. The results suggest that the Seashore Rhythm Test may prove to be a useful tool to detect young children who will later show signs of reading impairment. 相似文献

Primary school teachers rated the frequency of occurrence of 65 reading-related behavioral characteristics of Grade 1 to Grade
6 Chinese school children in Hong Kong. An item factor analysis based on ratings on 554 students yielded two major dimensions
of behavioral characteristics on reading and writing problems, and sequencing and spatial difficulties. In predicting the
literacy and cognitive skills of a separate sample of 184 school children, gender, age, and the two empirical scales developed
on the basis of factor analysis were used as predictors in regression analyses. The findings indicated that reading and writing
problems emerged as the most predominant predictor of various literacy and cognitive deficits. The two mean scores of behavioral
characteristics for children with dyslexia were significantly elevated as compared with those for children without dyslexia.
Implications of the findings for screening dyslexia and predicting specific cognitive deficits using classroom-based behavior
checklists are discussed. 相似文献

This study examined (1) whether working memory and higher-level languages skills—inferencing and comprehension monitoring—accounted for individual differences among Chinese children in Chinese reading comprehension, after controlling for age, Chinese word reading and oral language skills, and (2) whether children with specific language impairment (SLI) or dyslexia showed deficits in these skills. Eighty-two Cantonese Chinese-speaking children between the age of 7; 8–9; 5 were assessed. Regression analyses on the full sample offered support for the first question. The children were also classified into four groups: Typically-developing (TD; N = 34), specific language impairment-only (SLI-only; N = 18), SLI-dyslexia comorbid (SLI-D; N = 22) and dyslexia-only (D-only; N = 8). Pair-wise comparisons focusing on the second question revealed that both the SLI-only and the D-only group performed worse than the TD group in reading comprehension after controlling for age and nonverbal intelligence. The SLI-only and the D-only group showed a different profile of deficits: only the SLI-only group performed worse than the TD group in working memory, comprehension monitoring, and inferencing. The SLI-D comorbid group did worse than the SLI-only, but not the D-only group, in reading comprehension. The SLI-D comorbid group did not do worse than either single diagnosis group in the higher-level language skills associated with reading comprehension. These findings suggested adopting different intervention approaches for reading comprehension difficulties in children with SLI versus children with dyslexia. 相似文献

Electrophysiological correlates of dyslexic subtypes. 总被引：1，自引：0，他引：1
The construct validity of Boder's typology of dyslexia was investigated using quantified EEG. Thirty-nine children, ranging in age from 7-0 to 10-11, were recorded during a contextual reading task and at rest. During reading, children with dyslexia were expected to show increased theta and beta amplitude compared to nondisabled readers. These differences were expected in regions of presumed strength for each subtype as a sign of overengagement in task. Children with phonological deficits (dysphonetic dyslexia) were expected to adopt visuospatial processing strategies (right occipital-parietal activation), those with orthographic deficits (dyseidetic dyslexia) to emphasize phonetic strategies (left temporal-parietal activation). Results supported beta frequency differences in anticipated regions by subtype during the reading task. However, the direction of difference hypothesis was not supported. Decreased amplitudes in both groups with dyslexia compared to normally achieving readers suggest reconceptualization of the theoretical base for the Boder subtyping system. 相似文献

This paper is concerned with those who display positive indicators on tests for dyslexia but seemingly do not have any severe
literacy problems. A case study is presented by way of illustration. On the basis of data from the British Births Cohort Study
(12,905 10-year-old children), it was found that some seemingly normal achievers who showed signs of dyslexia (N=422) obtained
different results on five measures associated with dyslexia than did other normal achievers without such signs (N=4,998).
The measures used were: underachievement at word recognition; and underachievement at spelling, reading comprehension, pseudoword
reading, and mathematics. The proportion of boys to girls in the groups was also noted. It is suggested that these were cases
of mild dyslexia, who, on the basis simply of reading and spelling tests, might escape detection. The consequences for the
concept of dyslexia are discussed, and it is suggested that the needs of dyslexics with only mild literacy problems should
not be overlooked. 相似文献

A comprehensive test battery, including phonological, speed, motor and cerebellar tasks, was administered to the entire cohort of two schools for children with learning disabilities. Testing was undertaken blind without accessing the psychometric data on the children. Children were then allocated to a discrepancy group on the basis of their IQ, with the majority (n = 29) classified as nondiscrepant (IQ < 90) and a smaller set (n = 7), with IQ of at least 90, classified as discrepant (with dyslexia). Both groups showed significant deficits relative to age-matched controls on almost all the tests. On phonological, speed, and motor tasks, the nondiscrepant group were at least as severely impaired as the discrepant group. By contrast, on the cerebellar tests of postural stability and muscle tone, the nondiscrepant group performed significantly better than the children with dyslexia and close to the level of the controls. The findings indicate that cerebellar tests may prove a valuable method of differentiating between poor readers with and without IQ discrepancy. The findings are interpreted in terms of the cerebellar deficit hypothesis for dyslexia. 相似文献

The reading levels and reading strategies of 43 children with genetic dyslexia, right-hemisphere lesions/dysfunction, and
left-hemisphere lesions/dysfunction were retrospectively compared. Age and IQ were comparable. Only children who had a verbal
or performance IQ over 90 were included in the study. Although the genetic dyslexics had a significantly higher Full Scale
IQ than the other two groups, their reading level was significantly lower. This suggests that a disturbance of the normal
processes of neuronal migration during fetal development may have profound effects on specific cognitive processes, without
affecting others. In contrast, 50 percent of the boys with left-hemisphere deficits were disabled readers. One-third of the
boys with right-hemisphere deficits were also poor readers. With one exception, the girls, who had comparable deficits, were
good readers. A comparison was made between the groups in terms of reading strategies and patterns of errors. 相似文献

Cooperative teaching is the result of efforts made by two educators for teaching a heterogeneous group of students, especially one including those with specific needs, due to reading disorders for instance. The present study serves as an experimental investigation focusing on the effect of cooperative teaching on the development of reading skills among students with a reading disorder. To achieve this, three female students were selected from a regular primary school in the 2nd education district of Tabriz, Iran. The research design was a multiple baseline single subject design with different children, in which we used the reading and dyslexia test (RDT) and the revised Wechsler Intelligence Scale to diagnose reading disorders, and a researcher‐made hundred‐word test to measure the development of reading skills. The children received five cooperative teaching sessions during only the (experimental) intervention, i.e. in the baseline and the follow‐up stages, they were not exposed to any cooperative teaching. The comparisons of the students’ performance in experimental phases showed that cooperative teaching is an effective technique for developing reading skills and that the effectiveness of this technique was also maintained over time. This work is the first empirical demonstration of the effectiveness of co‐teaching in dealing with dyslexic reading disabilities. It additionally serves as the first instance of applying co‐teaching to any form of reading disability in Iran. 相似文献
