Self-events and other-events: temporal dating and event memory.

A diary methodology was used to assess factors related to temporal dating and cued recall of real-world events. In one diary, participants kept a record of unique personal autobiographical events. In a second diary, participants recorded unique events from the life of a friend or relation. At the time each event was recorded, participants rated the event's pleasantness, person typicality, and degree of initial mental involvement in the event. At the end of the academic quarter, participants provided a recall rating, a rehearsal rating, a date estimate, and a report of the strategy used to estimate the date for each event. Results of regression analyses indicated that both self-events and other-events were characterized by superior memory for person-atypical events. Furthermore, there was a positivity bias in recall for self-events, but there was a negativity bias in recall for other-events. Mediational analyses indicated that the self-event positivity bias was due to enhanced mental involvement when the events occurred, whereas the other-event negativity bias was due to subsequent event rehearsal. The date estimation results indicated that self-event dating was more accurate and evinced less telescoping than other-event dating. Furthermore, the accuracy of date estimates was substantially mediated by event memory. However, mediational differences between self-events and other-events did not emerge. The theoretical implications of these results are discussed.
