Autobiographical memory questionnaire results. Age tended to be the technique used by most participants to recall autobiographical memories older than 5 years. A one-way analysis of variance showed a significant main effect of past period (F_(9,81) = 19.23, p < 0.0001). A post-hoc test revealed that the incidence of subjects using age to recall events was significantly increased for events that occurred 20 and 30 years prior to testing, compared with events that had occurred on the day of testing through to 3 years prior (p < 0.05 for all values)
