Mood-congruent false memories persist over time

Knott, L. & Thorley, C. (2014). Mood-congruent false memories persist over time. Cognition and Emotion, 28(5), pp. 903-912. doi: 10.1080/02699931.2013.860016


In this study we examined the role of mood-congruency and retention interval on the false recognition of emotion laden items using the Deese/Roediger-McDermott (DRM) paradigm. Previous research has shown a mood-congruent false memory enhancement during immediate recognition tasks. The present study examined the persistence of this effect following a one-week delay. Participants were placed in a negative or neutral mood, presented with negative-emotion and neutral-emotion DRM word lists, and administered with both immediate and delayed recognition tests. Results showed that a negative mood state increased remember judgments for negative-emotion critical lures, in comparison to neutral-emotion critical lures, on both immediate and delayed testing. These findings are discussed in relation to theories of spreading activation and emotion enhanced memory, with consideration of the applied forensic implications of such findings.
