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 10 subtests comprising the Wechsler Intelligence Scale for Children--Revised (WISC-R) were independently factor analyzed for middle (N=107) and low (N=158) socioeconomic status children. After testing for equivalence of covariance matrices between the two groups, coefficients of congruence between factors were calculated. These coefficients…

Compared the performance of Caucasian kindergartners (N=60) on the Stanford Binet, the Leiter International Performance Scale, and the Metropolitan Achievement Test. Results confirmed that the LIPS measures mental traits similar to the SB, although some scores were different. The LIPS is especially useful with hearing or speech impaired children.…

Examined the validity of a parallel form of the Primary Mental Abilities test for use with adults aged 50 to 90 years. Significant intraindividual performance gains on the parallel form were observed on the verbal and number subtests, while the effect on space and reasoning subtests was less substantial. (Author/JAC)
