Formation and Retrieval of Emotional Memories: An Investigation into Differences in Neural Oscillations using Time Frequency Analyses
(2022) PSYP01 20221Department of Psychology
- Abstract
- How do emotions influence our memory? While emotionally salient memories are typically found to be remembered better and more vividly than mundane events, emotion- memory interactions can also be maladaptive. Though ample research has emphasized the modulatory role of emotion in memory, much remains to be understood about the way in which emotions may modulate neural mechanisms underlying memory processes. In a novel 2x3 paired associates memory paradigm, the current study employed electroencephalography (EEG) to measure neural oscillatory activity during the formation and retrieval of episodic memories (N = 40). Using time-frequency analyses, we investigated if and how emotion modulates neural oscillatory patterns during memory encoding... (More)

In a novel 2x3 paired associates memory paradigm, the current study employed electroencephalography (EEG) to measure neural oscillatory activity during the formation and retrieval of episodic memories (N = 40). Using time-frequency analyses, we investigated if and how emotion modulates neural oscillatory patterns during memory encoding and retrieval. During encoding, we observed subsequent memory effects represented by expected alpha desynchronization and, contrary to previous work, theta desynchronization. At retrieval, we observed alpha desynchronization and theta synchronization in support of previous theory. Our findings suggest these memory effects are influenced by the emotional nature of the material presented to participants. In support of the prevailing information by desynchronization theory, we reconcile these findings by considering the influence of other relevant cognitive processes. (Less)
