Correlations between the Woodcock-Johnson Test of Cognitive Abilities (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were evaluated on a sample of 55 behavior disordered males, 28 of whom were also diagnosed as learning disabled. Concurrent validity for this sample was demonstrated by only a 2.33 point difference between the mean WJTCA Broad Cognitive score and the mean WISC-R Full Scale IQ score. Analysis of Pearson product-moment correlations between each WISC-R subtest and each Woodcock-Johnson cluster score substantiated previous assertions that the WJTCA is unduly weighted with Product-Dominant factors. Construct validity of some of the WJTCA clusters also was questioned. Implications of these results for behavior disordered populations were discussed. 相似文献

This study investigated the construct validity of the Kaufman Assessment Battery for Children (K-ABC) via correlational procedures with the WISC-R. Thirty-two special population children selected from kindergarten through grade five participated in the study; 19 children were diagnosed as learning disabled, 13 as educable mentally retarded. A high relationship between the WISC-R FSIQ and the K-ABC Mental Processing composite revealed evidence of construct validity in the measurement of intelligence. The K-ABC diagnosed the learning disabled but failed to diagnose the mentally retarded children. The K-ABC Sequential Processing Scale appeared to offer a unique construct (analytic, temporal sequencing) not measured by the WISC-R. Implications for the usefulness of the K-ABC are discussed. 相似文献

A group of 80 mentally retarded youngsters, aged 6 to 16, was tested on the WISC-R, primarily to assess the continuity of measurement between the old and new WISCs. The WISC-R IQs correlated .65 to .82 with Stanford-Binet IQ for a subsample of 45 children, resembling the coefficients between the 1949 WISC and the Binet for retarded groups. In addition, the WISC-R test profiles for the 80 children corresponded closely to the WISC test profiles for many retarded samples. Thus, there was evidence to support the continuity of the WISC-R with its predecessor for retarded populations. 相似文献

This study compared the WISC-R and PPVT scores for a group of 65 students classified as mentally retarded, ranging in age from 7.5 to 14.5. Pearson product moments (r) and correlated t values were employed in the analysis of data. The evidence from the present study indicated that for this sample of mildly retarded children and youth, the PPVT IQ score is significantly higher than the Full Scale IQ from the WISC-R. The current findings indicate that the same general pattern exists for the WISC-R and PPVT as for the WISC and PPVT scores. 相似文献

Using a sample of 100 behavior disordered male adolescents, correlations between the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Tests of Cognitive Abilities (WJTCA) were computed. All WISC-R subtests correlated with the W-J Broad Cognitive Ability score at the .0001 level. Analysis of the forward selection multiple regression procedure resulted in the inclusion of only WISC-R Verbal subtests for the first six steps. Implications of such results were discussed and a predictive equation reported. 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

The aim of this investigation was to examine normal (N = 34), learning disabled (N = 34), and borderline mentally retarded (N = 33) children's performance on the WISC-R and K-ABC. Results revealed no significant differences between the WISC-R Full Scale IQ and K-ABC Mental Processing Composite by group (F = 0.7, p > .15). The Full Scale IQ and Mental Processing Composite standard score correlated .85 for the entire sample, and all other subscale correlations ranged from .65 to .90 (all significant at p < .001). Analysis of Verbal-Performance, Mental Processing-Achievement, and Simultaneous-Sequential discrepancy means by group revealed no significant differences in comparison to normative values. Subtest patterns analysis revealed high rank order correlations between the learning disabled and mentally retarded groups, but lower correlations between the exceptional and normal groups. Implications of these findings are discussed. 相似文献

In this investigation, indices of scatter on the WISC-R and McCarthy Scales were examined for 20 educable mentally retarded and 20 learning disabled children in relation to a similar control group. The scatter found in the two exceptional samples was also compared to the variability found in the standardization samples of the WISC-R and McCarthy. Results indicated that the learning-disabled sample exhibited more WISC-R subtest scatter and McCarthy Scale variability than the standardization sample but not more than the control group. The implications of these findings are discussed. 相似文献

The purpose of this study was to determine the degree of comparability between the WISC and the WISC-R over time. Hypotheses were tested using a sample of 276 mildly mentally handicapped children enrolled in special education classes who had received a WISC (Trial 1) and a WISC or WISC-R (Trial 2) after an interval of approximately three years. The sample was grouped on the basis of test administered in Trial 2. Group I contained those children who received the WISC on Trial 2 and included 183 children, of whom 121 were males and 62 were females. Mean age at time of initial testing was 8–10; mean age at second testing was 11–8. Group II was composed of 93 children who had been posttested on the WISC-R and included 72 males and 21 females. Mean age at initial testing was 9–5; mean age at posttest was 13–0. The study was conducted in five school districts and one county department of education. Verbal IQ, Performance IQ, and Full Scale IQ for both instruments administered were transcribed from the special education folders of the children. The design used to test hypotheses was repeated measures analysis of variance. Data analysis resulted in rejection of the hypotheses that the WISC-R yields mean Verbal, Performance, and Full Scale IQ scores greater than or equal to the corresponding mean IQ scores of the WISC. It was concluded that the WISC-R may unfairly penalize special education children who are reevaluated with this instrument. Fluctuations in IQ scores due to the instrument of measurement must be recognized, and appropriate action should be taken to insure that children are evaluated for special class placement on comparable bases. 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

The purpose was to compare the performance of normal and educable mentally retarded children on pattern recognition tasks. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of children to find: (a) duplicate patterns and same elements as presented in model pattern sequences; (b) opposite patterns and same elements as presented in model pattern sequences; and (c) duplicate patterns but different elements than presented in model pattern sequences. The normal and mentally retarded children were matched on mental age derived from individual and group intelligence tests. Results indicated significant differences in performance measures between groups and various pattern tasks. The data support the suppositions that: (a) mentally retarded children and normal children show the same type of progression through the hierarchical arrangement of pattern tasks; and (b) mentally retarded children show a slower progression through the hierarchy than normal children when matched on mental age. Educational implications from this study are discussed. 相似文献

The performance of a sample of moderately mentally retarded children on the McCarthy Scales of Children's Abilities (MSCA) was investigated by comparing their obtained mental age (MA) scores with their Stanford-Binet MAs and Minnesota Child Development Inventory (MCDI) developmental ages (DAs). All three MA estimates correlated significantly, and there were no significant differences among mean MAs. However, valid MSCA Index scores could not be obtained for these moderately retarded children, using the current normative tables. Therefore, the MSCA cannot be recommended for measuring the intellectual level of retarded children for educational classification purposes. 相似文献

This study examined the effects of different types of reinforcement on the performance of black males who had been diagnosed as being mildly mentally retarded, using the WISC-R. After each correct response, participants were given no reinforcement, a candy reward, traditional social reinforcement, or culturally relevant social reinforcement. Children given tangible or culturally relevant rewards obtained significantly higher scores than did children given either no reinforcement or traditional social reinforcement. 相似文献

PPVT and WISC-R scores were compared for 259 students ranging in age from 6 to 16. In descending order, Pearson product correlations ranked best for the total sample, emotionally disabled, regular class, mentally retarded, and learning disabled. In all groups, the PPVT overestimated ability and was significantly different from the WISC-R scores as measured by correlated t-tests. 相似文献

对10-14岁(平均年龄12、13岁)的37名不同智商的弱智儿童的敲击动作速度进行了测定.弱智儿童根据智商不同分为二组一组为轻度智力残疾,智商55-75,平均智商61.3;一组为中度智力残疾,智商38-51,平均智商42.8.实验使用一台BQS-80-Ⅱ型敲击仪进行.被试各测定左、右手一分钟的敲击动作速度.结果表明智商较低的一组弱智儿童(平均智商42.8)左、右手的敲击动作速度均明显较之智商较高的一组弱智儿童(平均智商61.3)为慢,前者只相当于正常7岁儿童水平.无论哪一组弱智儿童,右手敲击速度均快于左手速度.这种情况表明,在弱智儿童中,由于智商的差异,也会对简单的动作速度产生影响. 相似文献

The paper reviews WISC/WISC-R comparison studies which have been conducted with a wide variety of samples. Significant WISC/WISC-R IQ score differences have been reported with the WISC-R yielding consistently lower scores of approximately 5-8 IQ points for the three major scales. Several studies do report variable WISC/WISC-R differences for various ages, races, and ability levels. These results have implications for practicing school psychologists. Caution is advised in the interpretation of a WISC/WISC-R difference, as a discrepancy of one SD may not be meaningful. Many students who scored in the borderline classification range on the WISC and who are currently being readministered the WISC-R are scoring in the mentally impaired classification range. This does not necessarily reflect negatively on the validity of the WISC-R, but does document the need to keep intelligence tests up to date. There is a continuing need to exercise caution in the use of individual intelligence tests and to utilize data in addition to WISC-R scores in order to make special education placement decisions. 相似文献

Thirty children ages 6-10 were selected who had been referred for psychological evaluation from the public schools. WISC-R was significantly lower than WISC FS IQs and similar to S-B L&M IQs (1972). Each scale predicts reading, spelling, and achievement in a significant manner. The use of the WISC-R over the WISC will rosult in greater numbers of children being classified as retarded. 相似文献

Ninety exceptional children—30 emotionally handicapped (EH), 30 learning disabled (LD), and 30 educable mentally retarded (EMR)—attending public, self-contained classrooms in the Southeast were systematically selected from a master list of all exceptional students (1,355) who had been referred for placement within the last 4 years. All available data used in the placement process, i.e., WISC-R profiles, Key Math scores, and teacher rating scale scores, were obtained by a search of the children's permanent records. To determine the relative effectiveness of the assessment devices in contributing to appropriate placement decisions, a MANOVA with subsequent univariate analyses and multiple discriminant function analyses was employed. Results indicated that both the LD and the EH groups differed significantly from the EMR group, and that classification results for all groups were inadequate. 相似文献
