Normative data for the Advanced Raven's Progressive Matrices are presented based on 300 University of California, Berkeley, students. Correlations with the Wechsler Adult Intelligence Scale and the Terman Concept Mastery Test are explored. The relationship between the Advanced Raven's Progressive Matrices and Spearman's g is explored. (Author)

Compared the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R) in a sample of college students (N=70). A highly significant test order interaction was found. The WAIS-R will result in significantly higher ability estimates when administered following the WAIS than the WAIS will when following the WAIS-R. (JAC)

A cross-racial comparison of the Wechsler Adult Intelligence Scale (WAIS) was made with the revised version, the WAIS-R. Three groups of Anglo, Black, and Mexican-American male college students were administered both versions of the WAIS on the same day. Significant differences were found among the racial groups.

Two studies (N=4,261 persons) illustrate an inverse relationship between ability level and correlations among IQ measures. Low IQ subjects showed higher correlations than did high IQ subjects. Intercorrelations of IQ subtests, intercorrelations of cognitive ability measures, and correlations of IQ with measures of cognitive ability displayed the…
