Abstract

Emotional events have been shown to protect individuals against false memory when remembering scripted material. Whether the same is true also for older adults, however, is unclear, and it has been investigated in the present study. Seventy-six older adults (age range 65-89 years) were presented with a series of photographs depicting scripted events. Each event included the consequence of an action whose corresponding cause was not presented; the consequence was either neutral, negative, or positive. False recognitions of unseen causes of the consequences (i.e., 'causal errors') were calculated. A Bayesian inferential approach was adopted in order to include evidence from previous studies and to use it as a benchmark for newly collected information. Older adults showed enhanced false memories and lower accuracy than previously reported in studies on young adults. Compared to neutral ones, both negative and positive events were associated with fewer false memories in older adults. The emotional false memory 'profile' of older adults was very similar, in terms of the effect size, to the one previously found in young adults, although the overall chances of older adults incurring errors were higher. Results are discussed considering both cognitive and socioemotional hypotheses on emotional memory in late adulthood.
