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

The purpose of this study was to provide an empirical basis for the interpretation of the WISC-R performance of Navajo children according to the Luria-Das Model of Simultaneous and Successive cognitive processes. Two groups of Native American Navajo subjects, 45 learning disabled and 41 gifted, were given the WISC-R. The scores on those subtests expected to involve Successive and Simultaneous processes were factor analyzed for each group and two factors were extracted. The factors, essentially similar for both samples, were interpreted to reflect the Successive and the Simultaneous modes of processing information as suggested by the Luria-Das Model. The gifted and learning disabled children had disparate loadings for some of the subtests, suggesting that the two groups may be using distinct modes of coding information. 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

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

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

The summed scores of the WISC-R dyad, Vocabulary and Block Design, were cross-tabulated with full scale WISC-R scores for 249 children referred to a gifted program. The initial results indicated that the Vocabulary-Block Design dyad could be a useful tool in predicting full scale IQ for some children and thus leave time available for other types of assessment of students. 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

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

Twenty-nine children with a diagnosis of Attention Deficit Hyperactive Disorder (ADHD) were compared to a group of 21 emotionally disturbed (ED) children and a control group (CO) of 20 nonproblem children. The meaures used in the comparison were the 12 subtests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Stroop Color and Word Test (SCWT). The results showed that the CO group was superior to the ADHD and ED groups and that the ED group performed better than the ADHD group on most of the variables. A stepwise discriminant function analysis showed that similar WISC-R subtests differentiated between the ADHD group and the ED and CO groups. Two measures of the SCWT helped in discriminating between the ADHD and ED groups, but not between the ADHD and CO groups. The authors discuss the meaning of these findings and their contribution to better understanding of the ADHD group, its specific cognitive processing, and its problems. 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 present study was undertaken to examine scatter analysis and Kaufman regroupings of WISC-R scores. Thirty-one non-learning-disabled children (NLD) and 29 learning-disabled children (LD) determined by individual IQ and achievement scores served as subjects. Scatter indices were computed within the Verbal and Performance subtests as well as between the Verbal and Performance IQ scales. Also, the regrouping categories proposed by Kaufman (1979) were examined. A significant difference in Verbal and Performance IQs was found between the LD and NLD group. Significantly more students in the LD group exhibited the Kaufman regrouping pattern than in the NLD group (p < .01). These results suggest that Kaufman regroupings and Verbal-Performance scatter analysis may be used to assist in diagnosing LD children. 相似文献

Fifty-four elementary-age gifted students were administered the K-ABC. To determine construct validity of the test for this population, the factor structure was obtained for mental processing and achievement subtests and then compared to the factor structure obtained for children from the standardization sample via a procedure that determines factor structure similiarity between groups. Except for minor variations, the factor structure for the gifted children was very similar to that for nongifted children in the standardization sample. However, the most parsimonious structure accounted for slightly less than 40% of the shared test variance, which leads to questions about the advisability of educational program planning based on obtained scores. 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

Children who had been nominated as potential candidates for gifted programs were assessed to determine the relationships among certain behavioral and intellectual characteristics. Records were compiled listing 132 first- through eighth-grade children's race, sex, age, grade level, Slosson Intelligence Test (SIT) IQ scores, Scale for Rating Behavioral Characteristics of Superior Students (SRBCSS) scores, and WISC-R IQs. Only children achieving SIT IQs of 130 or higher were included. A regression equation for the prediction of a WISC-R Full Scale IQ score from a given SIT score was computed and compared to that developed for predicting the WISC-R IQ in another study. All variables except SIT IQ were poor predictors of WISC-R IQ scores. A moderate correlation was computed between SIT and WISC-R Verbal and Full Scale IQ scores. A somewhat lower, but still significant, degree of relationship was found between SIT and WISC-R Performance IQ scores. Some difficulties with using the SIT as a screen for gifted programs are discussed. 相似文献

The basic question addressed in this study was whether the discrepancies found between the Mental Processing Composite (ability component) and the Achievement subtests of the Kaufman Assessment Battery for Children (K-ABC) corresponded with the discrepancies found between the WISC-R Full Scale IQ and the PIAT subtests, or whether use of the K-ABC over the WISC-R and PIAT results in the identification of different students. The differences were evaluated using four standard score procedures for calculating a severe discrepancy. It was found that the K-ABC and WISC-R/PIAT approaches to the determination of a score difference resulted in the identification of different populations of students. The high average PIAT standard scores together with the lower subtest reliabilities appeared to be the primary source of disparity between the K-ABC and WISC-R/PIAT comparisons. 相似文献

WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. Individual subtests from the two scales were unevenly correlated with grades in specific school subjects over both school years. Data suggest that while the two scales may be grossly equivalent as global predictors of school achievement, the individual subtests from the two scales may not correlate equivalently with specific external criteria such as school grades. 相似文献

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R were compared in two samples of children. In the first sample, there were 34 black and 27 white rural Southeastern Alabama children being considered for special education classes. In the second sample, there were 4 black and 81 white suburban Alabama children being considered for classes for the talented and gifted. In both samples, correlations between the SIT IQ and WISC-R Full Scale IQ were significant (rs of .70 and .48, respectively). However, in the special education sample, SIT IQs were significantly higher than WISC-R Full Scale IQs by about 7 points. The results from both samples provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the IQs on the two tests may not be interchangeable. 相似文献

This study investigated sex differences on the WISC-R subtests for retarded males and females who were matched in terms of WISC-R Full Scale IQs. The sample consisted of 126 children and youth (63 females, 63 males) ranging in chronological age from 7–3 to 8–3, with a mean CA of 7–8. Each subject was matched in terms of Full Scale IQ score. A 2 × 10 analysis of variance with repeated measures on a single factor was used to analyze the data. Students' T and Fisher's F ratios were calculated, and differences between subtest means were analyzed by Newman-Keuls test for sample effects. Evidence from the investigation indicated that a significant interaction effect existed between sex and subtest scores. 相似文献

This study investigated the best short form version of the WISC-R for learning disabled (LD) students. The WISC-R was administered to 234 LD and 290 children who were referred for psychological evaluation but were found not eligible (NE) for special education services from 45 school districts in Michigan. Stepwise multiple regressions were calculated to ascertain the best tetrads of Full Scale IQ (FS IQ) for the two groups. For the NE sample, Vocabulary, Picture Arrangement, Picture Completion, and Information were the best four indicators of FS IQ, accounting for about 80% of the variance in Full Scale scores. For the LD sample, the best four predictors of FS IQ were Similarities, Block Design, Picture Completion, and Vocabulary, accounting for about 80% of criterion variance. Using the WISC-R standardization data, Sattler identified the Information, Vocabulary, Comprehension, and Block Design subtests as one of the best short form versions for predicting FS IQ. For the LD sample of the present study, Sattler's composite yielded a multiple R of .873 with FS IQ, whereas our best four predictors yielded a multiple R of .896. It appears that Sattler's tetrad is about as good a predictor of FS IQ for LD students as that found in the present data. 相似文献
