Abstract
Male and female hamsters were trained to barpress for saccharin. Half of each group was gonadectomized and tested for response rate for saccharin reinforcement under water deprived and nondeprived conditions. Gonadectomized females did not differ from intact females in response rate or weight gain. Gonadectomized males gained more weight and barpressed less than intact males. These data were discussed as failing to support any current theory dealing with the effects of alterations in gonadal hormones on preference behavior.
