Adolescents (n=43) previously diagnosed as dyslexic/reading disabled had markedly lower IQ scores on the newly standardized Wechsler Intelligence Scale for Children (WISC-III) than on the earlier administered WISC-R. The declines for Verbal, Performance, and Full Scale IQs were 10, 12, and 11 points, respectively, which were twice as great as in a subset of the standardization sample given both versions of the WISC. The adolescents did not show a significant decline in standard scores from the Wide Range Achievement Test (Level I to Level II). However, only two subjects had current reading and spelling standard scores above the 25th percentile. The impact of lower WISC-III IQs on guidelines for classification of students as learning disabled is discussed. 相似文献

Each year thousands of children are evaluated or reevaluated utilizing the current edition of the Wechsler Intelligence Scale to determine their eligibility for gifted programs. The Wechsler Intelligence Scale for Children-III (1991) is new enough that only limited research is available on how it compares to the previously used Wechsler Intelligence Scale for Children-Revised (1974). The purpose of this study was to determine the comparability between the previously dominant intelligence scale, the WISC-R, and the revised WISC-III with gifted children. The results of this study indicate that the latest revision (WISC-III) and the earlier version (WISC-R) produce remarkably similar scale and subtest scores when administered under clinical conditions to gifted children. All 51 children determined eligible through the administration of one of these two Wechsler tests would have been eligible for services had the other test been administered. The Verbal and Performance scale IQ scores were within two points of each other across the two test administrations, while only a one-point difference existed between the Full Scale IQ scores. The Arithmetic, Comprehension, and Object Assembly subtest scores were in high agreement across the two administrations (p<.01). The level of agreement between some subtests across the two administrations suggests that clinical judgment is just as important as scores in considering who is eligible for gifted programs. 相似文献

This study was designed to examine the role of intelligence (IQ) in the definition of reading disabilities (RD) in languages with different orthographic systems. A sample of 94 Spanish children and 157 English-speaking Canadian children with RD was classified into four groups on the basis of IQ scores from the Wechsler Intelligence Scale for Children-Revised (< 80; 81-90; 91-109; 110-140). We examined the reading and spelling skills of Canadian and Spanish children as a function of Full Scale, Verbal, and Performance IQ scores. Significant differences between the languages were found when reading performance was analyzed as a function of Verbal IQ scores, in that there were some differences between the groups of Canadian children with RD but not between the groups of Spanish children. The Canadian children with Verbal IQ scores < 80 demonstrated relatively lower performance in reading and spelling skills than the Canadian groups with higher IQ scores. There were differences in reading tasks as a function of Performance IQ in English but not in Spanish. The differences in the role of IQ as a function of orthographic systems may relate to the greater significance of visual-orthographic as opposed to phonological processing in English. 相似文献

The purpose of the present study was to examine the relationship between the Wechsler Intelligence Test for Children-III and the Wide Range Achievement Test, 3rd Edition. The study investigated the scores of 37 children in a rural Arkansas school district who were referred for evaluation because of academic difficulties. The children ranged in age from 6 to 16 years and included 35 Whites and 2 Blacks, with 22 males and 15 females. The findings indicated that the WRAT3 correlations with the WISC-III ranged from .42 to .66. These findings are consistent with others on the general correlations between IQ and achievement test scores. 相似文献

To test the construct validity of brief measures of intelligence and explore how well these instruments relate to academic performance, the WPPSI-R, the Kaufman Brief Intelligence Scale (K-BIT), Draw-A-Person: Quantitative Scoring System (DAP:QSS), and the K-ABC Achievement Scale were administered to 50 kindergarten and first-grade children. Results indicated that all measures provide similar scores, all in the average range. All brief measures related significantly to academic achievement. Implications of the findings are discussed, and a battery for screening young children is offered. 相似文献

As part of a mandated three-year reevaluation, the Differential Ability Scales (DAS) was administered to 53 children identified as having a learning disability approximately 3 years after each had been administered the Wechsler Intelligence Scale for Children—Third Edition (WISC-III). The DAS's General Conceptual Ability score (GCA), and Verbal and Spatial Cluster scores were nonsignificantly different from the WISC-III's Full Scale, Verbal, and Performance scores. The Nonverbal Reasoning score of the DAS (a measure of Fluid intelligence not assessed by the WISC-III) was significantly different from both the Verbal and Performance scores. High correlations were found between the similar constructs on the two tests. Approximately 96% of the students obtaining a certain classification from the WISC-III obtained a comparable classification from the DAS. © 1996 John Wiley & Sons, Inc. 相似文献

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) and the Kaufman Test of Educational Achievement (K-TEA; Kaufman & Kaufman, 1985) are commonly used in the identification of children for special educational services. However, there is little evidence about the relationship between these two tests among children with handicapping conditions. This study examined the relationship between the WISC-III IQs and K-TEA standard scores in a sample of 72 children with emotional handicaps. The results revealed a significant positive relationship between scores on these instruments. © 1996 John Wiley & Sons, Inc. 相似文献

The degree of WISC-III intersubtest scatter was normal and similar for 66 children with LD and 51 children without LD, but the pattern of scores differed. In the 8- to 16-year-old sample, children with LD scored lower on the Freedom from Distractibility Index relative to FSIQ than children without LD. This difference was found in both the ADHD and nonADHD subgroups, suggesting that children with LD may have an attention deficit even if they do not meet the diagnostic criteria for ADHD. The CAD profile was evident in the mean scores for both the LD/ADHD and LD/nonADHD subgroups, but it was not found among the lowest subtest scores for any of the nonLD subgroups. Though WISC-III profile types were apparent in LD group data, only a minority of individual children with LD actually had these profiles. In the 6- and 7-year-old group, children with and without LD were indistinguishable on the WISC-III, which may reflect the difficulty of ruling out LD at this young age. © 1998 John Wiley & Sons, Inc. 相似文献

Because of the Flynn effect, IQ scores rise as a test norm ages but drop on the introduction of a newly revised test norm. The purpose of the current study was to determine the impact of the Flynn effect on learning disability (LD) diagnoses, the most prevalent special education diagnosis in the United States. Using a longitudinal sample of 875 school children who were initially diagnosed with LD on the Wechsler Intelligence Scale for Children-Revised (WISC-R), children experienced a significant decline in IQ when retested on the third edition of the WISC (WISC-III) compared to peers who were tested on the WISC-R twice. Furthermore, results from logistic regression analyses revealed that the probability of a rediagnosis of LD on reevaluation significantly decreased, in part, because of this decline on the WISC-III. These results are discussed in terms of their implications for both basic research and educational policy. 相似文献

The relationship of phonological awareness, rapid naming, and verbal memory to severe reading and spelling disability. 总被引：3，自引：0，他引：3
A Cornwall 《Journal of learning disabilities》1992,25(8):532-538
The present study examined the relationship of phonological awareness, naming speed, and verbal memory to the scores obtained from five tests assessing word attack, word identification, reading comprehension, and spelling skills in 54 children with severe reading disabilities (48 boys and 6 girls; M age = 9 years, 7 months). Multiple regression analyses indicated that the best predictor of achievement across the five academic tests was the Verbal Comprehension factor from the Wechsler Intelligence Scale for Children-Revised. Age, socioeconomic status (SES), and externalizing behavior problems were also significant predictors of achievement, depending on the academic measure. After controlling for age, SES, behavior problems, and intelligence, the phonological awareness task added significantly to the prediction of word attack, spelling, and reading comprehension scores; rapid letter naming added significantly to the prediction of word identification and prose passage speed and accuracy scores; and a word-list memory task added significantly to the prediction of word recognition scores. These results suggest that several independent processes interact to determine the extent and severity of reading problems. 相似文献

Patterns of performance on the Wechsler Intelligence Scale for Children-Revised (WISC-R) have been proposed as useful tools for the identification of children with learning disabilities (LD). However, most of the studies of WISC-R patterns in children with LD have been plagued by the lack of a typically achieving comparison group, by failure to measure individual patterns, and by the lack of a precise definition of LD. In an attempt to address these flaws and to assess the presence of patterns of performance on the WISC-R, we examined data from 121 children with typical achievement (TA), 143 children with reading disabilities (RD), and 100 children with a specific arithmetic disability (AD), ages 6 to 16 years. The results indicated that the RD and AD groups had significantly lower scores than the TA group on all the Verbal IQ subtests. Many of the children with AD and RD showed a significant difference between Verbal and Performance IQ scores, but so did many of the typically achieving children. Although there were some children with LD who showed the predicted patterns, typically, 65% or more of the children with LD did not. Furthermore, a proportion of the TA group-generally not significantly smaller than that of the RD and AD groups-showed discrepancy patterns as well. Our results indicate that the patterns of performance on intelligence tests are not reliable enough for the diagnosis of LD in individual children. Therefore, it might be more profitable to base the detection of an individual's LD on patterns of achievement test scores. 相似文献

The relationship between the K-BIT, the Stanford-Binet, a two-subtest short form, and the K-TEA was examined with a population of 75 academically referred students. The K-BIT correlated significantly with the Stanford-Binet (.81) and the K-TEA Math (.57), Reading (.58), and Spelling (.47) scores. The mean K-BIT IQ Composite (76.5) averaged 5.1 points lower than the mean Stanford-Binet Test Composite (81.6). The results tend to support the use of the K-BIT as a screening instrument when the Stanford-Binet is the follow-up or comprehensive measure of intelligence. 相似文献

The K-BIT and the WISC-R were administered in counterbalanced order to 35 referred students. Although the K-BIT IQ Composite correlated significantly with the WISC-R Full Scale IQ scores (r=.81), the mean scores differed significantly (difference = 6.2 points; p<.001). The results provide moderate support for the K-BIT as a screening instrument when the WISC-R is the follow-up or comprehensive measure of intelligence. 相似文献

The Stanford-Binet IV and the WISC-III were administered in counterbalanced order to 31 subjects, aged 11 to 17 years, who were previously identified as functioning in the range of mild mental retardation. The correlations among the scores on the two tests were significant, but the Stanford-Binet IV Composite IQ was higher than the WISC-III Full Scale IQ for 29 of 31 subjects. The results suggest that children identified as functioning in the range of mental retardation on the WISC-III could be identified as functioning at a higher level if the Stanford-Binet IV were used. The consistency of the results points to the need for the use of multiple criteria in making decisions regarding educational accommodation. © 1996 John Wiley & Sons, Inc. 相似文献

Relationship between home literacy environment and reading achievement in children with reading disabilities 总被引：3，自引：0，他引：3
Past research has indicated that a significant relationship exists between young children's early home literacy environment and their reading-related skills. However, this relationship has rarely been investigated among older children with reading disabilities (RD). In the present study, the relationship between parent and child home literacy activities and children's academic functioning was investigated with a sample of 65 elementary-age children with RD. The results indicated that children's home literacy activities were not significantly related to any of their academic abilities, whereas parents' home literacy activities were significantly related to children's passage comprehension and spelling scores. However, relationships between home literacy environment and reading may be different for children with and without RD. 相似文献

This study investigated the performance of 166 special education students who had been administered the WISC-R and approximately 3 years later the WISC-III. The sample ranged in age from 6.0 to 16.6 years. The scores were analyzed using Pearson product moment correlation coefficients and t tests of the differences between means for related samples. The results indicated that there was a significant, positive correlation among global scales (p < .001). This finding suggests that the WISC-R and the WISC-III IQ scores measure similar abilities. Analysis of mean IQ score differences revealed significant differences in the WISC-R and the WISC-III IQ scores, with the WISC-III global scores being lower. Implications for the evaluation of students for special education are discussed, with special emphasis on the role and function of the psychologist practicing in the schools. © 1996 John Wiley & Sons, Inc. 相似文献

Regrouping Wechsler Intelligence Scale for Children‐Third Edition (WISC‐III) subtests into Bannatyne's spatial, conceptual, and sequential patterns has been thought by many to identify children with learning disabilities (LD). This study investigated the prevalence and diagnostic utility of WISC‐III Bannatyne patterns by comparing 1,302 children with LD to 2,158 children in the WISC‐III normative sample. Further analysis was conducted on a subsample of students with specific reading disabilities. Results indicated that the presence of the Bannatyne WISC‐III pattern would not lead to decisions that are useful in differentiating children with LD from children without LD. For example, receiver operating characteristic (ROC) analysis, measured by the area under the curve (AUC), indicated that the Bannatyne WISC‐III pattern exhibited low diagnostic utility (AUC = 0.54–0.55). Due to its inaccuracy, use of the Bannatyne WISC‐III pattern is not recommended. 相似文献

Over the past decade, educators and researchers concerned about children with reading disabilities have called for widespread adoption of early identification tools and early effective programming. This call may be the result of, in part, what Stanovich calls "Matthew effects in reading." That is, when stakeholders delay identification and support for young children struggling to read, the variance of individual differences in reading will inevitably increase, creating a widening of the gap between strong and struggling readers. In this longitudinal study, reading achievement data from 382 children were collected as they progressed from kindergarten through Grade 3. In kindergarten, children were screened with a battery of phonological awareness measures. Percentile rank scores were collected, and children were identified as having poor, average, or strong phonological awareness. As children moved through Grades 1, 2, and 3, reading-based data were collected in the spring of each year. Results indicated that, in general, as children progressed from kindergarten to Grade 3, those in lower ranks of reading achievement were likely to remain in the lower ranks, and furthermore, at each progressing data collection point struggling readers fell further behind their grade-level reading peers. In other words, as each year passed the variance between strong and struggling readers increased significantly. The authors hypothesized that this finding is consistent with the "Matthew effect"-the rich were getting richer while the poor were getting poorer. 相似文献
