Temporal distribution of autobiographical memory: Uncovering the reminiscence bump in Japanese young and middle-aged adults1

Abstract

The reminiscence bump is the effect that people recall more personal events from their teenage period than from adjacent lifetime periods. The effect is generally found in studies that divide the results of participants, who were at least 40 years old, into age bins of 10 years. In this study, the temporal distribution of autobiographical memories of Japanese young and middle-aged adults was examined. Because the questionnaire was presented on the internet, many participants could take part (N = 252). By dividing the personal events into smaller age bins and applying a mathematical method that corrects for the increased recall of recent events, a reminiscence bump could be identified in the memories of young adults. The location of the reminiscence bump of young adults was similar to the location of the reminiscence bump of middle-aged adults.
