Suppressing memory associations impacts decision-making preference: Evidence from the think/no-think paradigm

Conscious Cogn. 2024 Feb;118:103643. doi: 10.1016/j.concog.2024.103643. Epub 2024 Jan 14.ABSTRACTRecent research has suggested that episodic memory can guide our decision-making. Forgetting is one essential characteristic of memory. If certain memories are suppressed to be forgotten, decisions that rely on such memories should be impacted. So far, little research has examined whether suppression of episodic memory would impact decision-making. In the current pre-registered study, the effect of memory suppression on subsequent reinforcement decision-making was examined by combining the Think/No-think paradigm and a reinforcement decision-making task. We found that suppressing memories of learned associations significantly impaired recollected memories of those associations, and participants' decision bias disappeared after their memory associations were suppressed. Furthermore, the more memory associations participants recalled, the higher decision preferences they exhibited. Our findings provide additional support for the role of episodic memory in reinforcement decision-making, and suggest that suppressing memory associations can lead to behavioral consequences.PMID:38224648 | DOI:10.1016/j.concog.2024.103643
