The effect of emotion on associative memory is still an open question. Our aim was to test whether discrepant findings are due to differential impact of emotion on different types of associative memory or to differences in the way participants encoded stimuli across studies. We examined the effect of negative content on multiple forms of associative memory, using the same encoding task. Two registered experiments were conducted in parallel with random allocation of participants to experiments. Each experiment included 4 encoding (...) blocks, in which participants read a neutral text comprised of 6 paragraphs, which were interleaved with neutral or negative images. Images were controlled for visual properties and semantic similarity. Memory tests included recognition memory, Remember/Know, order memory, temporal source memory and contextual memory. Analyses showed that emotion decreased contextual memory but not order memory or temporal source memory. We also found that temporal source memory and contextual memory were correlated. Recognition accuracy and subjective recollection were not impacted by emotion. In agreement with previous work, participants self-reported a reduced ability to integrate blocks containing negative images with paragraphs. In contrast to our hypothesis, results suggest that emotion does not impact all types of associative memory when stimuli are controlled. (shrink)

We argue that while the proposed memory model by Bastin et al. can explain familiarity-based memory judgements through the interaction of a core representation system and an attribution system, recollection-based memory judgements are not based on non-mnemonic signals being attributed to memory.

Remembering when emotional experiences occurred can be adaptive, yet there is no consensus on how emotion influences temporal aspects of memory. Temporal memory, a type of associative memory, refers to the capacity to encode, store, and retrieve information about the sequence and timing of events. This Special Issue presents evidence on how emotion affects three aspects of temporal memory: temporal-order, temporal source, and event segmentation. The contributions suggest that emotion often increases temporal-order memory, a result that is harder to reconcile (...) with some dominant emotional memory theories, including the Object-Based Framework, the Dual Representation Account or other trade-off models, but may fit with Arousal-Biased Competition theory. The contributions also suggest that emotion can act as a boundary between events, although only under some experimental set-ups. Findings regarding its effect on temporal source memory were less clear. We discuss the diversity of findings in light of theories of emotional associative memory and methodological factors, such as the direction of the shift in emotional experience and discrepancies between temporal-order and temporal distance measures as indices of event boundaries. We provide a roadmap for future studies aimed at understanding how emotion shapes the fate of our memories as they unfold in time. (shrink)
