ABSTRACT Though emotion conveys memory benefits, it does not enhance memory equally for all aspects of an experience nor for all types of emotional events. In this review, I outline the behavioral evidence for arousal's focal enhancements of memory and describe the neural processes that may support those focal enhancements. I also present behavioral evidence to suggest that these focal enhancements occur more often for negative experiences than for positive ones. This effect of valence appears to arise because of valence-dependent effects on the neural processes recruited during episodic encoding and retrieval, with negative affect associated with increased engagement of sensory processes and positive affect leading to enhanced recruitment of conceptual processes.

    • "Discrimination between old and new action events was larger for emotional than for neutral events for both younger and older adults, demonstrating that emotion enhanced memory for actions regardless of age. There was a nonsignificant trend for negative emotion to enhance memory for actions more than positive emotion which is consistent with Kensinger's (2009) hypothesis that negative emotion enhances memory more than positive emotion.

    ABSTRACT: When remembering an event, it is important to remember both the features of the event (e.g., a person and an action), and the connections among features (e.g., who performed which action). Emotion often enhances memory for stimulus features, but the relationship between emotion and the binding of features in memory is unclear. Younger and older adults attempted to remember events in which a person performed a negative, positive, or neutral action. Memory for the action was enhanced by emotion, but emotion did not enhance the ability of participants to remember which person performed which action. Older adults were more likely than younger adults to make binding errors in which they incorrectly remembered a familiar actor performing a familiar action that had actually been performed by someone else, and this age-related associative deficit was found for both neutral and emotional actions. Emotion increased correct recognition of old events for older and younger adults but also increased false recognition of events in which a familiar actor performed a familiar action that had been performed by someone else. Thus, although emotion may enhance memory for the features of an event, it does not increase the accuracy of remembering who performed which action.

    • "It is known that emotion is important for memory recall : for example , memories that are emotional are even easier to recall than memories that have been specifically attempted to be remembered ( Heuer and Reisberg , 1990 ) . Similarly , emotional memories ( regardless of valence ) are recalled better than neutral ones ( although there are differential effects for negative and positive emotions : Kensinger , 2009 ) . Walker ( 2009 ) notes that emotional memories are retained , though the emotion itself is reduced over time . "

    ABSTRACT: In this paper we propose an emotion assimilation function of sleep and dreaming. We offer explanations both for the mechanisms by which waking-life memories are initially selected for processing during sleep, and for the mechanisms by which those memories are subsequently transformed during sleep. We propose that emotions act as a marker for information to be selectively processed during sleep, including consolidation into long term memory structures and integration into pre-existing memory networks; that dreaming reflects these emotion assimilation processes; and that the associations between memory fragments activated during sleep give rise to measureable elements of dream metaphor and hyperassociativity. The latter are a direct reflection, and the phenomenological experience, of emotional memory assimilation processes occurring during sleep. While many theories previously have posited a role for emotion processing and/or emotional memory consolidation during sleep and dreaming, sleep theories often do not take enough account of important dream science data, yet dream research, when conducted systematically and under ideal conditions, can greatly enhance theorizing around the functions of sleep. Similarly, dream theories often fail to consider the implications of sleep-dependent memory research, which can augment our understanding of dream functioning. Here, we offer a synthesized view, taking detailed account of both sleep and dream data and theories. We draw on extensive literature from sleep and dream experiments and theories, including often-overlooked data from dream science which we believe reflects sleep phenomenology, to bring together important ideas and findings from both domains.

    • "Although we do not have a clear explanation for this finding, we can entertain several possibilities. First, studies have shown that negative information can be remembered more easily and with a greater sense of vividness and detail than positive information (e.g., Kensinger, 2009; Mickley & Kensinger, 2008), and our particular instructions may have emphasized the need to generate the type of vivid details during episodic simulation that are more easily associated to negative than positive events. Moreover, limiting the time that participants had to respond on each trial might have favored the negative condition, as imaging a positive future event may have required placing an experience in a more elaborate context than imaging a negative future event.

    ABSTRACT: People often think of themselves and their experiences in a more positive light than is objectively justified. Inhibitory control processes may promote this positivity bias by modulating the accessibility of negative thoughts and episodes from the past, which then limits their influence in the construction of imagined future events. We tested this hypothesis by investigating the correlation between retrieval-induced forgetting and the extent to which individuals imagine positive and negative episodic future events. First, we measured performance on a task requiring participants to imagine personal episodic events (either positive or negative), and then we correlated that measure with retrieval-induced forgetting. As predicted, individuals who exhibited higher levels of retrieval-induced forgetting imagined fewer negative episodic future events than did individuals who exhibited lower levels of retrieval-induced forgetting. This finding provides new insight into the possible role of retrieval-induced forgetting in autobiographical memory.
