As part of the first phase of a prospective longitudinal study on alcoholism, a battery of neuropsychological tests covering general intelligence, memory, attention, field-dependence, categorizing ability, and organizing and planning, was administered to 204 18-19-year-old males. Of these, 134 subjects are the sons of alcoholic fathers and are thereby themselves at high risk for becoming alcoholic. The remaining 70 subjects comprise a control group matched for several social and familial variables. The high risk group was found to have a relatively poorer vocabulary and to perform worse on tests of categorizing ability and organization and planning. All of these findings concur with other results from this study. The anticipated future alcoholics from among the high risk subjects may prove to be those who differed most on these tests.
