Unpacking the Impact of Retrieval Context: Investigating the Emotionality of Odor-Evoked Autobiographical Memory with the Single Cue Delayed Rating Method.

The assessment of odor-evoked autobiographical memories (OEAMs) typically yields in the finding that OEAMs are more emotional compared to autobiographical memories (AMs) evoked by other modalities. To date, there are only speculations as to why this could be the case, which range from neuroanatomical explanations - the olfactory sense has a unique neural pathway that projects into the amygdala and limbic areas - to the idea that the olfactory sense could play a more important role in the emotional period of childhood. Notably, prior studies in this domain share a design feature: the retrieval and evaluation of AMs occurs in close temporal proximity. Thus, we hypothesize that there could be a misattribution of the heightened emotionality of processing the odor to the evaluation of the retrieved AM. To test this hypothesis, we implemented a new method, the so-called Single Cue Delayed Rating Method. Analogous to the typical methods, participants are presented with stimuli of different modalities and asked to retrieve AMs in response. Importantly, for half of the AMs the ratings are obtained immediately, while half of the ratings are conferred to a follow-up session. In our study, 60 participants had to retrieve AMs in response to odors and words. The follow-up session was four weeks later. If the misattribution hypothesis is valid, we expect heightened emotionality of OEAMs compared to word-evoked AMs only in the immediate, but not the delayed rating condition, since the possible spill-over effect of the processing of the odor should not persist for 4 weeks.
