Abstract
Sex differences in response rates were observed during acquisition of behavior on different random ratio schedules of reinforcement. Intact male rats responded at higher rates than intact female rats. Response rates of castrated males were found to be lower than response rates of intact males. Differences were not observed between intact and ovariectomized females.Entities:
