Abstract
Autobiographical memory (AM) refers to memory for personally significant events and experiences. Though the retrieved outcome of autobiographical memory (e.g., narratives) have been well researched, the dynamic processes involved in search and access and subsequent elaboration of autobiographical memories are only beginning to be explored. Moreover, it is unclear how factors such as gender and emotion influence the AM retrieval process. In the present study, we developed a novel application of pupillometry to study effects of gender and emotion as participants retrieved and typed narratives of emotional autobiographical events. Participants produced more words and had a longer duration of typing for emotional narratives than non-emotional narratives; females used more words and typed for longer relative to males. A longitudinal analysis applied to the pupillary dilation revealed a curvilinear trend of pupil dilation. The effects of gender emerged over time. For males only, pupil size was negatively correlated to the number of emotional words in their narratives. This study confirmed the promising application of pupillometry to the study of AM retrieval, and further explored the temporal process of the effects of gender and emotion on AM retrieval.
