The influence of memory on approach and avoidance decisions: Investigating the role of episodic memory in social...

People are motivated to make social decisions to approach or avoid social targets (i.e., other people). Prior work has shown people make approach/avoidance (AA) decisions based on factors like physical appearance, race, gender, sexuality, etc., but less work has investigated the extent that memory for past encounters with social targets might influence AA decisions. Here, we investigate the role of episodic memory (memory for specific details associated with specific social targets) on AA decisions. In this investigation, participants formed positive or negative impressions based on social targets' behaviors before completing a memory test for specific episodic details associated with targets (self-generated impressions formed about target; behavior associated with targets). Participants then made AA decisions for those social targets, as well as new targets. Results showed strong approach tendencies when participants correctly remembered positive details associated with targets (impressions; behaviors) and strong avoidance tendencies when participants correctly remembered negative impressions associated with targets. For novel targets (targets not seen before and thus not associated with prior memory representations), participants showed no approach or avoidance tendencies. Overall, these findings suggest an important role for episodic memory on AA decisions, which is a potentially important mechanism in social decisions.
