When compared with nonalcoholics, chronic alcoholics and their children show significant deficits in the processing of visuospatial information. The literature supports two possible explanations of a visuospatial processing deficit in the child of an alcoholic (COA) when compared with the child of a nonalcoholic (NCOA). Ether the COA may suffer cognitive disruptions produced by personal and social development within an alcoholic family, or the COA may inherit or very early develop alterations in central nervous system substrates of neurocognitive operations. The present study was designed to continue our examinations of visuospatial information processing differences and the source of these differences in COAs. An evaluation of very young subjects not only assisted in providing a more complete view of visuospatial processing across the COA's life span, but also helped explain why the deficit occurs. Thirty matched male and female preschool children, aged 35.8–51.6 months, served as participants. Fifteen children were COAs from families in which the biological father and two other relatives had an alcoholism history. The other group of 15 children were NCOAs. Each child performed a visuospatial learning task similar to the task used in previous studies of older COAs. The visuospatial learning performance of the preschool COAs was inferior to that displayed by preschool NCOAs. The patterns of correct, error, and nonresponses emitted by the preschool COAs and the interrelationships of these data closely resembled the data from our previous studies of older children, adolescent, and adult COAs. The consistency of the deficit and its underlying processes in COAs sampled across the life span from different family environments support a model of visuospatial deficit that is more neurocognitive inheritance than personal/developmental.
