Odor Evoked Autobiographical Memory: A Pilot Study for Finding Appropriate Odors in Turkish Population

Presented by: Berçem Yar
Evidence shows that olfactory evoked personal memories are different from information evoked by the primary senses. Most such studies were carried out in countries such as Germany, the Netherlands, Sweden. Cross-cultural studies show that the role and attributed importance of odors differ in different cultures. This means that there may also be cross-cultural differences in the features of olfactory evoked autobiographical memories. There is a need for studies in different cultures, which then may contribute to our understanding of the mechanisms underlying the Proust phenomenon. In this pilot study, we aim to identify a subset of odors that are effective in evoking autobiographical memories. The enrollment target is 30 participants, of which 6 participant have been completed so far. A total of 30 cues were used to elicit autobiographical memories. Items were generated by replication of some stimuli used by other studies and also by inclusion of items that would be meaningful to a Turkish population. The study conducted in a single session. Participants were exposed to olfactory cues for 30 sec and asked to relate any autobiographical memory for the given cue. 3 minutes was allowed for retrieval. When a memory was evoked, the participant provided a short description of the event, rated emotional valence of the memory and then the familiarity, pleasantness and disgustingness of the odors. A preliminary analysis of the results of 6 participants showed that on average the odors are rated as familiar, as pleasant and emotions of both positive and negative valence are experienced. Importantly, most odors evoke autobiographical memories.We draw a tentative conclusion that effective odors that are culturally appropriate for Türkiye are in the selected set of odors. Once the ongoing data collection is completed, a subset of odors that can be identified less effective in evoking autobiographical memories will be excluded for use in future studies.
