Peer reviewedSpitz, Herman H. – Intelligence, 1989
Studies involving groups administered the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised were examined to determine the validity of J. R. Flynn's (1987) findings of massive intelligence quotient gains in a single generation in many nations. Results for sampled adults support Flynn for the average intelligence range only. (TJH)

Peer reviewedFeingold, Arnold – Sex Roles: A Journal of Research, 1993
Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)
