The present study attempted to develop a quantitative model using the WISC-R that could be used to predict those students most likely to be successful in gifted education programs. The study was conducted in two phases using two groups of gifted children. In phase one, 120 elementary students randomly chosen from a pullout program in a suburban school served as the subject pool. The subjects had varying degrees of success in the program. Phase one subject data were used to develop a quantitative model; phase two subjects were used for predictive purposes. Specific results in phase one yielded six maximally discriminant WISC-R subtests. These subtests were then used to predict at well above chance levels (87.8%) those students who were known to have been either marginally or highly successful in the program (n = 41). The present study goes one step beyond previous research by using these maximally discriminant subtests to predict program performance of gifted children. 相似文献

Intellectual patterns of gifted students with learning disabilities were studied to determine cognitive factors characterizing these children. Twenty-four gifted children with learning disabilities (LD) and a control group of nondisabled gifted children were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) (Wechsler, 1974). While differences between the two groups on individual subtests were examined, a comparison of broader factors was emphasized in discovering cognitive patterns that might suggest effective intervention. Experimental and control performances were compared on 14 factor scores, using cognitive classification systems of Bannatyne (1971), Kaufman (1975), Rapaport, Gill, and Schafer (1946), and Wechsler (1974). Gifted students with LD were more reliant on verbal conceptualization and reasoning than the control students. They also demonstrated deficiencies in short-term auditory memory and sound discrimination. The gifted group with LD exhibited the Organic Brain Syndrome factor (Wechsler, 1974) to a significantly greater extent than did the control group. 相似文献

The study investigated cultural bias in the 79 items of the three verbal tests of the Wechsler Intelligence Scale for Children-Revised (WISC-R). The Information, Similarities, and Vocabulary subtests were administered to 40 Anglo and 40 Native- American Navajo subjects matched for grade level. The responses of the two groups of subjects on individual items were analyzed by log-linear technique using the likelihood ratio chi-square statistic. The findings revealed that performance of subjects was homogeneous across groups on most of the items of three verbal subtests of the WISC-R. Only 15 (19%) of the 79 items comprising Information, Similarities, and Vocabulary subtests were found to be biased against the Navajo sample. Five of these items are from the Information, four from the Similarities, and the remaining six items are from the Vocabulary subtest. Implications of these findings for the psychoeducational assessment of minority children were discussed. 相似文献

WISC-R factor structures (Principal Factor Analysis-Varimax rotation) were compared for previously diagnosed samples of learning disabled Navajo and Papago children. Both two- and three-factor solutions were analyzed, utilizing coefficients of congruence. Both groups were similar in terms of proportion of common factor variance accounted for by a general factor, and the Verbal-Performance distinction was demonstrated in both groups. 相似文献

This study was designed to determine if three diagnostic groups of Navajo children differed on intellectual dimensions as measured by the WISC-R. Subjects had been previously diagnosed by state certified professionals and were identified as nonhan dicapped (NH) (N = 113), educationally disadvantaged.(ED) (N = 189), and learning disabled (LD) (N = 150). NH group means on all WISC-R variables were significantly higher than the LD group means. The ED and the LD group means were similar on the verbal measures, but the LD group scores were lower than the ED group scores on performance measures. The NH group demonstrated intellectual abilities and deficits similar to those reported for other primary-grade Navajo children who had not been referred for suspected handicapping conditions. 相似文献

WISC-R subtest scaled scores for 192 learning disabled Navajo Indian children were recategorized according to the system recommended by Bannatyne (1974), and subsequently analyzed using a one-way repeated measures analysis of variance. A Newman-Keuls Multiple Range Test was also conducted to determine significant pairwise comparisons. Results indicated that, as a group, the subjects failed to demonstrate the Spatial>Conceptual>Sequential pattern predicted by Bannatyne (1974). Implications for use of Bannatyne's system with learning disabled minority children are discussed. 相似文献

Three tests of receptive language were administered to thirty children enrolled in regular, gifted, and learning disabled‐gifted programs. Analyses of variance indicated that the Token Test for Children differentiated the learning disabled‐gifted children and the Verbal Absurdities Subtest of the Detroit Tests of Learning Aptitude differentiated the gifted children from the other two groups. 相似文献

Thirty learning disabled students of average intellectual ability between 16 and 17 years of age were given both the WISC-R and the WAIS-R to determine if the WAIS-R provided higher average IQ scores, as had been reported for educationally mentally retarded adolescents. The results indicated: (a) no significant differences between the two scales on either the Verbal, Performance, or Full Scale IQs, (b) significant correlations between the WISC-R and WAIS-R on the three IQ scores and 9 of the 11 subtests, and (c) the emergence of the ACID profile for learning disabled adolescents on both tests. 相似文献

This study compared the WISC-R performance of 40 children ranging in age from 6–6 to 15–10, referred to a university center for suspected learning disabilities, with that of two clinically defined groups of learning disabled children. The university center children were found to have WISC-R profiles similar to those of the learning disabled children, with higher overall levels of performance. It was speculated that these children avoid classification as learning disabled by virtue of possessing higher cognitive abilities than those children who are classified. Implications were raised concerning the role of university centers with children experiencing learning difficulties and the accuracy of parental perceptions of learning disabilities. 相似文献

The purpose of this study was to examine the relationship of the Kaufman Assessment Battery for Children (K-ABC), the WISC-R, and the Woodcock-Johnson Psychoeducational Battery (W-JPB), Part Two, with children who experience learning disabilities. Correlational analyses were used to examine relationships among the WISC-R, K-ABC Mental Processing and Achievement scales, and the W-JPB Achievement scales. Thirty-four children with learning disabilities (mean age 8–11 years) received all three measures. Correlation coefficients indicated stronger and more consistent relationships between the WISC-R and W-JPB Achievement tests than between the K-ABC and W-JPB Achievement tests. Significant relationships between the WISC-R Full Scale IQ and the K-ABC Mental Processing Composite (MPC) revealed evidence of validity for this learning disabled sample. However, correlation coefficients among the K-ABC Achievement subtests and the W-JPB Achievement clusters indicated both convergent and discriminant validity. Thus, it is suggested that both the K-ABC MPC, for assessment of cognitive abilities, and the W-JPB Achievement clusters could be employed in discrepancy formulas for special education placement of children with learning disabilities. 相似文献

The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to 56 learning disabled children, using standard assessment procedures and format as outlined by Wechsler. Abbreviated IQ scores were then derived by applying the Kennedy-Elder formula, and equation that uses five WISC-R subtests with varied weightings. Comparisons between the standard IQ scores and the abbreviated IQ scores were evaluated. A Pearson product-moment correlation coefficient of .83 and a non-significant t-test between the mean IQs suggested the two scores were interchangeable. However, frequent IQ classification changes (23%) rendered the K-E format unacceptable for this population. 相似文献

This study analyzed WISC-R profiles along a three-factor approach (Spatial; Verbal-Comprehensive; Attention-Concentration), as suggested by Bannatyne (1968) for purposes of differential diagnosis. The WISC-R profiles of 278 school-verified learning disabled children were compared to those of four other groups: Educable Mentally Impaired (N = 141), Emotionally Impaired (N = 67), Otherwise Impaired (N = 61), and Nonimpaired (N = 294). The total sample was drawn from the State of Michigan public schools. Statistically significant differences were found between the learning disabled group and the other four groups on WISC-R subtest scores. Further analysis revealed that 36% of the learning disabled and 32% of normal children exhibited this WISC-R profile. Analysis of WISC-R profiles of Spatial→Verbal→Attention was not useful in differential diagnosis among the five groups. The results are discussed in terms of the limited utility of a three-factor analysis of WISC-R subtest scores for the purpose of differential diagnosis. 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

Full WISC-R evaluations of students who are referred to a gifted program, but who do not meet placement criteria, have become a drain on the resources of many school districts. A screening formula for gifted students, utilizing three WISC-R subtests (VO-BD-SI), was evaluated using traditional epidemiologic techniques. The screen was applied to the records of 200 students who had been referred for a gifted program and received complete WISC-R batteries. Screen results were compared to actual placement of the 200 subjects based on a WISC-R Full Scale, Verbal, or Performance IQ of 130 or more. Measures of sensitivity, specificity, and predictive value of the screen were determined. The screen correctly detected the majority of gifted students and could have major implications in terms of cost effectiveness and professional time management. 相似文献

Students referred by teachers for a gifted program and students referred for evaluation because of learning difficulties were asked a series of questions about their highest and lowest subtest scores on the WISC-R. Both groups tended to view Performance subtests as best, and the correlations between particular subtests perceived as best or worst and actual scores were significant. For free response attributions, no students ascribed success or failure to luck, and very few mentioned effort. High-achieving students credited ability as most responsible for their best subtest. No significant difference between the groups was found, however, when students rated the relative importance of ability, effort, task difficulty, and luck. Equal proportions of students in both groups expressed preferences for continued work on their best or worst subtest. 相似文献

Forty-seven talented fourth graders were assessed on different WISC-R short-form combinations in order to determine which short-form was the most effective predictor of high Full Scale WISC-R IQ. The short-form combinations of Similarities + Object Assembly + Vocabulary subtests (SI-OA-VO) or Similarities + Object Assembly subtests (SI-OA) were more effective in this regard than eight other WISC-R short-form combinations, the Slosson Intelligence Test, and school grades in Math, Language, and Reading combined. The findings are of relevance to gifted assessment. 相似文献

A group of 41 learning disabled children in Hawaii, aged 6 to 151/2, were tested on the WISC-R. Two main questions were explored: (a) Do the separate WISC-R tests assess “g” for learning disabled children to the same degree that they do for normal children? (b) Is there significantly more scatter among the tests for learning disabled than for normal youngsters? The answers to these questions were interpreted in terms of their diagnostic significance. 相似文献

Subtest scatter on the WISC-R was examined by analyzing Verbal-Performance IQ discrepancies, subtest scaled-score ranges and subtest scaled-score standard deviations of 290 psychoeducationally normal 9-year-old children whose IQs ranged from 100 to 140+. Although there were no differences between average and superior IQ groups on the Verbal-Performance discrepancy measure, substantial differences were found on the measures of subtest scatter where higher IQ groups exhibited substantially more scatter. The results suggest the need for caution in attempting to employ WISC-R subtest scatter as an indicator of learning disabilities with gifted students. 相似文献

The Kaufman Assessment Battery for Children (K-ABC) purports to assess fluid and crystallized intelligence via processing and achievement subtests, respectively. Eight K-ABC Mental Processing and five K-ABC Achievement subtests were administered to 41 gifted students. Scores were subsequently compared to concurrent achievement measures from the California Achievement Test (CAT), as well as previously obtained mental ability measures (Wechsler Intelligence Scale for Children-Revised [WISC-R], Stanford-Binet [SB], and Wide Range Achievement Test [WRAT] achievement scores). In general, K-ABC mental ability scores were lower than WISC-R and SB IQs. K-ABC achievement scores were consistent with K-ABC mental ability scores, but more highly related to SB and WISC-R VIQ (r = .42 and .40, respectively) than to WISC-R FSIQ (r = .16) and PIQ (r = .09), or to the K-ABC Mental Processing (Composite r = .17), Simultaneous Processing (r = .08), and Sequential Processing scores (r = .20). With the exception of WRAT Word Recognition, WRAT, K-ABC, and CAT achievement scores were similar. The patterns of intercorrelations suggest that the K-ABC achievement scores are more verbally loaded than are the CAT and WRAT achievement measures. 相似文献
