A comparison of involuntary autobiographical memory retrievals

This study compared three different ways autobiographical memories are elicited involuntarily: (1) cued by an active goal common to memory and retrieval contexts in combination with sensory information associated with this goal-directed activity; (2) cued by sensory information that does not relate to goal-directed activity common to both memory and retrieval contexts; and (3) activated when no identifiable cue present in retrieval context. Two hundred and twenty eight participants recorded details of a single autobiographical memory that resulted naturally from a spontaneous, non-deliberate retrieval. Nearly all recorded memories described specific events (83%) with very few memories less than 7 days old (8%) and many memories more than 5 years old (44%). No significant differences resulted between the three retrieval types for the age, specificity or prior rehearsal of memories reported. However, the level of attention at retrieval was significantly more diffuse for retrievals without a clearly identifiable cue. The authors discuss the implications of these findings for current models of involuntary autobiographical memory retrieval. Copyright (c) 2006 John Wiley & Sons, Ltd.
