Sex differences and residual effects of food deprivation in the satiated rat.

Following 100 days of food deprivation, during which 9 male and 9 female albino rats received acquisition and extinction training in a runway, and following 2 mo of ad lib feeding, Ss were given a reacquisition test under satiated conditions. Results indicate that females were significantly superior in running speed and frequency of food consumption during satiated reacquisition; while there was a large performance decrement in males following the drive shift, females performed at about the same level during satiation as during food deprivation.
