Differences in emotional bias effect on working memory in elderly.


This study investigated age-related differences in the inhibition mechanism for negative emotional information and in the facilitation mechanism for positive emotional information in working memory. Thirty-six older and thirty-six younger adults performed three RSTs: the neutral, negative, and positive emotional conditions. For each RST condition, all target words were neutral words, while the sentences themselves corresponded to the conditions. In older adults, the percentage of correct responses in the negative condition was worse than that of the neutral condition. Conversely, in younger adults, there was no significant difference between the neutral and negative conditions. In contrast, performance in the positive condition was better than the neutral condition for both age groups. These results suggest that the inhibition of negative information comes at a greater cost to older adults compared to younger adults, but the benefit of the positive information is the same in both age groups.
