Abstract
: The effects of emotional stimuli on memory in older adults are often addressed in terms of socio-emotional selectivity theory and the valence dimension. Older adults usually remember positive stimuli better than negative stimuli. However, studies examining the effects of discrete emotions on the elderly are still limited. The present study examined the effects of negative and positive discrete emotions (fear, disgust, and happiness) on recognition memory of older and younger adults. : In the encoding phase, participants studied happiness-, disgust-, fear-, and neutral- related photos while doing a line discrimination task that assessed their attention. After 45 minutes, they completed an old/new recognition memory test on a confidence rating scale and also rated self-relevance of photos. : Younger participants showed a more liberal response bias for disgust- and fear-related stimuli, and were also more accurate in recognizing disgust-related photos compared to others. Older adults showed a more liberal bias only for disgust-related stimuli, however, their recognition accuracy did not differ across emotion categories. : These results suggested that the effect of disgust-related stimuli on recognition memory may decrease with age and emotion effects cannot solely be accounted for by the valence/arousal dimensions.
