Differences in familiarity according to the cognitive reserve of healthy elderly people

subject

description

This study examines the relationship between cognitive reserve and familiarity processes in recognition memory. We hypothesize that people with high cognitive reserve are able to better compensate in alternative information retrieval processes. Forty-five participants, divided into high and low cogni- tive reserve groups, conducted a recognition experiment where they were asked to discriminate between studied and non-studied words that varied in perceptual familiarity. The results indicated that participants were able to use perceptual familiarity to improve their level of recognition. More importantly, people with high cognitive reserve used familiarity better than those with low cognitive reserve. The results provide the first empirical evidence indicating that people with high cognitive reserve are more efficient at balancing recol- lection and familiarity processes, and thus maintain a better performance level than those with low cognitive reserve.
