Some aspects of the development of sex differences in DRL behavior

Adult female rats acquired efficient DRL performance more rapidly than males. This sex difference was not observed in rats that began training as weanlings because both young males and females acquired efficient DRL performance about as rapidly as adult females and more rapidly than adult males. Although it is possible that proficiency on the DRL task declines with age in males, differences in the effortfulness of the response or the incentive value of the reward may explain the observed age difference.
