Autism spectrum disorder (ASD) is a neurodevelopmental disability that can cause significant social, communication, and behavioral challenges yet it is defined and diagnosed by the absence or presence of behaviors described in, for example, the Diagnostic and Statistical Manual 5. Descriptions of the disorder include symptoms such as intellectual…

The purpose of this study was to investigate the relation between early mathematical skills and cognitive processing abilities for two samples of children in Italy (N = 40) and the Netherlands (N = 59) who completed both a cognitive test that measures Planning, Attention, Simultaneous, and Successive (PASS) processing and an early mathematical…

Explored the relationship between the Revised Peabody Picture Vocabulary test (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) for a sample of 38 mentally retarded children. Found the PPVT-R correlated significantly with the WISC-R Verbal Performance and Full Scale IQ scores. (Author)

Relationships between the McCarthy General Cognitive Index and WISC-R Full Scale IQ with the Wide Range Achievement reading scores were explored with a sample of 20 educable mentally retarded and 20 learning disabled children, ages six to nine. (Author/SJL)

Explored the relationship between the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) for 37 Native American children. The PPVT-R standard scores correlated significantly with the WISCR-R Verbal IQ, Performance IQ, and Full Scale IQ. The mean PPVT-R standard score was significantly…

The Kaufman Assessment Battery for Children (K-ABC) and the Wechsler Intelligence for Children-Revised (WISC-R) were compared with respect to the magnitudes of the average White-Black differences in standardized scaled scores and in raw scores. Subjects were 172 fourth- and fifth-grade children matched in Black-White pairs. (Author/LMO)

Explored the relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Peabody Individual Achievement Test (PIAT) administered to a sample of 29 mentally retarded children. Findings indicated that the PPVT-R predicted achievement as measured by the PIAT only moderately; and that PPVT-R scores correlated with achievement…

Examined the relationships between the McCarthy Scales General Cognitive Index, the McCarthy Screening Test, Kaufman's McCarthy short form, and the Peabody Individual Achievement Test using a sample of elementary students. Found the Estimated General Cognitive Index by Kaufman's short form was virtually identical to the McCarthy Scales Index.…

Scores on Kaufman's (1977) McCarthy short form and the McCarthy Screening Test (1978) were obtained for first graders (N=53). As follow-up nine months later, the Metropolitan Achievement Test was administered. Results showed Kaufman's short form scores usually indicated a smaller number of false negatives than did McCarthy Screening Test scores.…

Compared the standard scores and age scores obtained from the Peabody Picture Vocabulary Test (PPVT)(1965) and the Revised Peabody Picture Vocabulary Test (PPVT-R)(1981) with (N=88) preschool children. Results found the mean PPVT IQ and Mental Age scores were significantly higher. Discusses implications for using the PPVT-R. (Author)
