Abstract
Three breeding pairs of rats were randomly assigned to one of three caffeine-exposure conditions (pre- and postnatal, postnatal, or control) to assess the effects of caffeine on barpressing. Pre- and postnatally exposed pups received .50 mg/ml of caffeine in their drinking water throughout gestation and thereafter. Postnatal pups received caffeine-adulterated drinking water only following birth. Control pups received plain tap water both pre- and postnatally. At 45 days of age, a series of 15 daily, 8-min barpress sessions began. The results indicated that postnatal-only exposure hindered performance, whereas pre- and postnatal exposure facilitated performance.
