In a longitudinal, prospective study, 95 children born to mothers who used cocaine and other drugs during pregnancy and 75 matched, nonexposed children born to mothers who had no evidence of alcohol or illicit substance use during pregnancy were evaluated for cognitive and behavioral outcome at 6 years of age. Prenatal exposure to cocaine and other drugs had no direct effect on the child's cognitive outcome (measured as IQ), but it had an indirect effect as mediated through the home environment. However, prenatal exposure to cocaine and other drugs did have a direct effect on the child's behavioral characteristics at 4-6 years of age, with the home environment having little impact. This study helps us to understand the fragile interaction of biological and environmental factors affecting the cognitive and behavioral development of children prenatally exposed to cocaine and other drugs.

Subjects were asked to indicate, by a simple motor response, the presence or absence of a predesignated target letter in unilaterally presented consonant trigrams. Perceptual sensitivity (d') was signficantly greater in the right visual hemifield and did not depend upon hand of response. Reaction times were slightly higher in the left hemifield and for the left hand. Response bias (beta) did not differ between hemifields. Models of perceptual asymmetry as a consequence of information loss transcallosally are weakened by the results.
