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)

Persons representing the extremes of intelligence cannot be included in the same study unless they are approximately equated on mental age, in which case the relative performances of the extreme groups can provide useful information about the nature of intelligence. (Author/RD)

Examines the relationship between (a) the Peabody Picture Vocabulary Test (PPVT), (b) the Slosson Intelligence Test (SIT), (c) Quick Test (QT) forms 1 and 3, and (d) the Wechsler Intelligence Scale for Children-Revised (WISC-R). Subjects were 93 students in grades 1 through 11 with suspected learning problems. (CM)

The effects of family income, parents' education, maternal employment, and family composition on the IQ scores of four- and seven-year-olds are estimated, using a sample of more than 3,000 children. The results suggest that childhood cognitive development plays a minor role in the intergenerational transmission of wealth. (Author/CT)

A new auditory measure of cognitive style (reflective-impulsive), a standard measure and intelligence scores were related to college students' reading performance. Only intelligence and errors on the auditory test contributed significantly to the variance of the reading measures. The importance of auditory factors in understanding adults' reading…

A study of 22 learning disabled (LD) and normal children (mean age nine years) was undertaken to illustrate the research problems involved in using analysis of covariance to control for differences between LD and normal children on measures of intelligence. (SW)

The predictive power of various cognitive skills at three months of age in terms of later cognitive functioning was examined. Visual habituation and recovery predicted later intellectual functioning at 24 months better than global intelligence or object permanence scores. Changes in cognitive functioning may be a transformation of skills.…

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 20 matched controls and to standardization samples. Exceptional children exhibited more subtest scatter and variability than the standardization sample but not more than the control group. (Author/RD)

Comparisons of the PPVT-R, the PPVT, and placement IQ tests were made with 114 educable mentally retarded students, 46 White, 44 Black, and 24 Hispanic. The PPVT and PPVT-R correlated for all groups, but neither the PPVT nor PPVT-R, correlated to a significant degree with the placement IQ tests. (Author/RC)

Examined the appropriateness and fairness of the WISC-R for four sociocultural groups in terms of comparability of factor structures, and construct validity. Groups were similar in proportion of variance. The verbal-performance scale distinction appeared appropriate for all groups. Conclusions provide increased confidence in construct validity of…

Principal factor solutions to the WISC-R were compared across race for Anglo and Chicano children. Additional comparisons of factor solutions were made with those for Anglo, Chicano, Black, and Papago students and the WISC-R standardization sample. Substantial congruence occurred across race. The two-factor solution was most appropriate for this…

The authors review problems associated with currently practiced matrix methods of identifying gifted students, describe an aggregation method utilizing a statistical approach involving standard scores, and relate the method to specific program examples. (SB)

Compared the subtest and IQ scores obtained by learning disabled and retarded children and youth on the Wechsler Intelligence Scale for Children (Revised) after a two-year time interval. Stability coefficients were obtained. The evidence indicated the WISC-R provides stable full-scale IQs. (Author)

Reports a study of the correlation between intellectual development and students' understanding of scientific concepts and science processes. Results are reported concerning the reliability and validity of Piagetian or Piagetian-like tasks as measures of students' level of formal reasoning. (Author/SA)

Results show that Peabody Picture Vocabulary Test (PPVT) IQs are not interchangeable with Wechsler Intelligence Scale for Children-Revised (WISC-R) IQs in a sample of reading disabled children. The PPVT yielded higher IQs on the average than did the WISC-R, supporting results obtained with learning disabled students. (Author/BEF)
