| Abstract | Both the human and animal literature report observations of marked age-related declines in cognitive functioning. The existing evidence indicates that the larger deficit involves the retention of newly learned behaviors, rather than the acquisition of those behaviors. However, one learning and memory paradigm, conditioned taste avoidances, suggests that aged animals show improvement in both learning and memory. Rather than displaying the usual decline in acquiring and maintaining a new behavior, aged animals show more robust learning and retention of these food-illness associations than younger cohorts. Following is a review of the age-related changes observed in the more traditional learning and memory paradigms, the age-related changes observed in the conditioned taste avoidance paradigm, hypotheses to explain the observed differences in both types of paradigms, and two preliminary experiments examining the impact of extinction on the reacquisition of a conditioned taste avoidance. |
