Comparison of performance of nine groups of mentally retarded subjects (N=236) on the Wechsler Intelligence Scale for Children Scale-Revised (WAIS-R) indicated the WAIS-R produced higher IQs than the WISC-R and that this disparity increased as WISC-R IQ decreased. (Author/DB)

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 reviewedSpitz, Herman H. – American Journal of Mental Deficiency, 1986
For mildly and moderately mentally retarded individuals, the Wechsler Adult Intelligence Scale-Revised measures at about the same level as the Wechsler Adult Intelligence Scale, and, consequently, it also produces much higher IQs than the Wechsler children's scales or the Stanford-Binet Intelligence Scale, Form L-M, despite high intertest…
