Self-defining memories in older adults: Distribution across lifespan and characteristics of the reminiscence bump

Many studies have investigated the temporal distribution of autobiographical memories, but none has focused on Self-Defining Memories (SDMs), i.e. memories that are particularly important for personal identity, in a large non-clinical sample. No study has examined the temporal distribution of Self-Defining Memories (SDMs), i.e. memories that are particularly important for personal identity, in a large non-clinical sample of older adults. Moreover, we examined for the first time the characteristics of SDMs located in RB. Two hundred and eighty elderly adults aged from 65 to 90 years old reported three SDMs. Participants were non-institutionalized retirees screened for global cognitive function. Participants were asked to recall three SDMs. They also completed the Mini-Mental State Examination. The period from 0 to 9 years corresponds to a very limited recall of SDMs. A RB appears between for the 10–24 years period. Recalled memories are enhanced after the age of 50. The temporal distribution of recalled SDMs differed according to thematic content and emotion. The percentage of positive SDMs was the highest in RB compared with other life periods. Specificity, meaning-making, tension, redemption and contamination did not differ for bump SDMs versus non-bump SDMs. In addition, differences between men and women were observed. Our results confirm the existence of the classical temporal distribution of autobiographical memories for SDMs. Recalling positive bump SDMs might improve well-being in older adults.
