Evaluating the Contribution of Emotional Valence to Associative Memory: Retrieval Practice Matters

Research has indicated that emotional valence can influence associative memory, but it is less clear whether it still works when the retrieval practice is controlled. The current study combined an associative recognition task with a paradigm of retrieval practice, with negative, neutral, and positive word pairs serving as stimuli. Results revealed that intact pairs possessed higher correct response proportions than rearranged, old+new, and new pairs; the rearranged pairs were more likely to be classified as intact; a negative impairment effect was observed in both learning conditions; the retrieval practice effect was sensitive to the interaction of emotional valence by pair type. We shows that the involvement of the recollection-driven process varies with pair type, providing telling evidence for the dual-process models; the occurrence of negative impairment effect conforms to the account of spontaneous interactive imagery; the contribution of desirable difficulty framework is modulated by the interaction of emotional valence by pair type.
