| Research Abstract |
In the Experiment 1, we compared explicit and implicit memory in the aged with those in the young, in terms of perceptual priming, conceptual priming and recognition. We found that although the magnitude of priming for the aged and the young was similar in the case of perceptual priming, there were differences in the levels of conceptual priming. Conceptual priming in the aged showed faster decay compared to perceptual priming. In terms of explicit memory, performance for the aged was worse than for the young, especially when items were encoded at the conceptual or semantic levels.
Experiment 2 dealt with procedural memory in the performance of problem solving tasks. The results showed that procedural memory in the aged is preserved at similar levels in the young. However, the quality of procedural memory in the young and the old differs, with procedural memory in the aged being based on motor-sensation processing, whereas this is based on cognitive-strategic processing in the young. In Experiment 3, although hypermnesia was found in the young, none was found in the old, however, it is uncertain why this was so.
