Abstract
Memory and aging: Recall, recognition and positive bias. The aim of the present study was to analyze the decay and maintenance of various aspects of the mnemic performance among the aged population and its potential relationship with a positive information processing bias. Thus, we compared recall and recognition performance in two groups of different ages (young, old). Results indicated that the free recall deficit found among the aged participants did not affect the serial position curve evenly, but took its toll in the absence of the primacy effect, whereas it left the recency effect intact. The data also showed that the ability to recognize information did not change with age, and revealed the presence of a positive recall bias even when the stimuli had no emotional content. A re-interpretation of Carstensen and colleagues' socio-emotional selectivity theory was used to account for the results.
