Fifty-eight students ranging in age from 8 to 11 years were administered the Matching Familiary Figures test and the Wechsler Intelligence Scale for Children-Revised (WISC-R). The primary purpose of the study was to determine if impulsive and reflective subjects differed on the major factors of the WISC-R. Reflective children scored significantly higher than impulsive children on the attention-concentration subtests and the visual organization subtests. The two groups did not differ significantly on the verbal comprehension subtests.
