Emotional stimuli (e.g. words, images) are often remembered better than neutral stimuli. However, little is known about how memory is affected by an environmentally induced emotional state (without any overtly emotional occurrences) – the focus of this study. Participants were randomly assigned to discovery (n = 305) and replication (n = 306) subsamples and viewed a desktop virtual environment before rating their emotions and completing objective (i.e. item, temporal-order, duration) and subjective (e.g. vividness, sensory detail, coherence) memory measures. In both (...) samples, a Partial Least Squares Correlation analysis showed that an emotional state characterised by high negative emotion (i.e. threat, fear, anxiety) and arousal was reliably associated with better memory in both objective (i.e. item) and subjective (i.e. vividness and sensory detail) domains. No reliable associations were observed for any temporal memory measures (objective or subjective). Thus, an environmentally induced state of negative emotion corresponds with enhanced memory for indices of episodic memory pertaining to “what” happened, but not necessarily “when” it happened.

Over twenty years of research have examined the cognitive consequences of positive affect states, and suggested that positive affect leads to a broadening of cognition (see review by Fredrickson, 2001). However, this research has primarily examined positive affect that is low in approach motivational intensity (e.g., contentment). More recently, we have systematically examined positive affect that varies in approach motivational intensity, and found that positive affect high in approach motivation (e.g., desire) narrows cognition, whereas positive affect low in approach motivation (...) broadens cognition (e.g., Gable & Harmon-Jones, Citation2008a; Harmon-Jones & Gable, 2009). In this article we will review past models and present a motivational dimension model of affect that expands understanding of how affective states influence attentional and cognitive breadth. We then review research that has varied the motivational intensity of positive and negative affect and found that affect of low motivational intensity broadens cognitive processes, whereas affect of high motivational intensity narrows cognitive processes.

Previous research has shown that moral failures increase compensatory behaviors, such as prosociality and even self-punishment, because they are strategies to re-establish one’s positive moral self-image. Do similar compensatory behaviors result from violations in normative eating practices? Three experiments explored the moral consequences of recalling instances of perceived excessive food consumption. In Experiment 1 we showed that women recalling an overeating (vs. neutral) experience reported more guilt and a desire to engage in prosocial behavior in the form of so-called self-sacrificing. (...) In Experimental 2 this logic was applied to actual spontaneous helping behaviors towards an experimenter, with participants who recalled an overeating (vs. neutral) experience exhibiting more such helping in the laboratory. Experimental 3 expanded the investigation to self-inflicted pain: Overeating (vs. neutral) recall led to higher levels of self-punishment as indicted by longer time periods spent engaging in the cold-pressor task. In sum, failures in normative food consumption can be viewed as moral transgressions that elicits both interpersonal and intrapersonal compensatory behaviors aimed at restoring a positive moral self-image.

Spontaneous intrusive recollections follow traumatic events in clinical and non-clinical populations. To determine whether any relationship exists between SIRs and enhanced memory for emotional events, participants viewed emotional or neutral films, had their memory for the films tested two days later, and estimated the number of SIRs they experienced for each film. SIR frequency related positively to memory strength, an effect more pronounced in the emotional condition. These findings represent the first demonstration of a relationship between SIRs occurring after an (...) emotional experience and subsequent memory strength for that experience. The results are consistent with the possibility that emotional arousal leads both to elevated SIR frequency and better memory, and that the covert rehearsal associated with SIRs enhances memory for emotional relative to neutral stimuli. Additional evidence of menstrual cycle influences on SIR incidence in female participants appears to merit consideration in future work. (shrink)

Emotional stimuli are consistently better remembered than neutral stimuli. However, the reported effects of emotional stimuli on source memory are less consistent. In four experiments, we examined spatial and temporal source memory and free recall for emotional words previously studied in an fMRI experiment. In the fMRI experiment, the unpleasant but not the pleasant words were shown to activate the amygdala. In the experiments reported here, spatial and temporal source memory were reduced for the unpleasant words compared to pleasant and (...) neutral words. Reduced spatial memory for unpleasant words was observed across studies that varied the specific stimuli, task conditions, and incidental versus intentional encoding instructions. Free recall was enhanced for the pleasant and unpleasant words compared to neutral words. The results demonstrate reduced source memory for unpleasant words even when item recall is enhanced. Our findings are consistent with prior reports of amygdala-mediated amnestic effects evoked by unpleasant stimuli. (shrink)

Emerging technologies raise the possibility that we may be able to treat trauma victims by pharmaceutically dampening factual or emotional aspects of their memories. Such technologies raise a panoply of legal and ethical issues. While many of these issues remain off in the distance, some have already arisen. In this brief commentary, I discuss a real-life case of memory erasure. The case reveals why the contours of our freedom of memory—our limited bundle of rights to control our memories and be (...) free of outside control—already merit some attention. (shrink)

ABSTRACTPrevious research has shown that, in comparison to neutral stimuli, false memories for high arousing negative stimuli are greater after very fast presentation and limited attention at study. However, full compared to limited attention conditions still produce comparably more false memories for all stimuli types. Research has also shown that emotional stimuli benefit from a period of consolidation. What effect would such consolidation have on false memory formation even when attention is limited at study? The aim of the present study (...) was to investigate the effect of fast presentation on false memory production for negatively-arousing and neutral items over time using the DRM paradigm. Sixty-eight participants studied Negative and neutral DRM lists with fast or slow presentation conditions. Half completed a recognition test immediately and half completed a recognition test after one-week. Results revealed that, for fast presentation, negative critical lures increased after one week and were comparab... (shrink)

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 result 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.

This study tested the hypothesis that overt rehearsal is sufficient to explain enhanced memory associated with emotion by experimentally manipulating rehearsal of emotional material. Participants viewed two sets of film clips, one set of emotional films and one set of relatively neutral films. One set of films was viewed in each of two sessions, with approximately 1 week between the sessions. Participants were given a free recall test of all of films viewed approximately 1 week after the second session. Rehearsal (...) was manipulated by instructing one group of participants not to discuss the films with anyone (no talkgroup) and instructing a second group to discuss both sets of films with at least three people (forced talkgroup). A third group consisted of participants instructed not to discuss the films with anyone, but who did not comply with these instructions (talkersgroup). All groups recalled significantly more of the emotional films than the neutral films. Furthermore, the relative number of emotional and neutral films recalled did not differ significantly among the three groups. The results indicate that overt rehearsal is insufficient to explain the enhancing effects of emotion on memory. (shrink)

Spontaneous intrusive recollections are known to follow emotional events in clinical and non-clinical populations. Previous work in our lab has found that women report more SIRs than men after exposure to emotional films, and that this effect is driven entirely by women in the luteal phase of the menstrual cycle. To replicate and extend this finding, participants viewed emotional films, provided saliva samples for sex hormone concentration analysis, and estimated SIR frequency following film viewing. Women in the luteal phase reported (...) significantly more SIRs than did women in the follicular phase, and SIR frequency significantly correlated with salivary progesterone levels. The results are consistent with an emerging pattern in the literature suggesting that menstrual cycle position of female participants can potently influence findings in numerous cognitive domains. The potential implications of these results for disorders characterized by intrusions, such as post-traumatic stress disorder, are also discussed. (shrink)

The effect of early emotional memories have been one of the most researched topics in modern scientific psychology. On the other hand, rigorous qualitative studies have been relatively rare, investigating the lived consequences of early emotional memories. The purpose of this paper is to report on some human scientific research results on the phenomenon, the lived persistent psychological meaning of early emotional memories. The study utilized Giorgi's descriptive phenomenological psychological method. A general psychological structure was discovered indicating constituents such as, (...) the vividness of early emotional memories; emotional needs coping strategies; everyday and life choices; as well as personal values attached to the meaning of an object that was present during the early emotional situation . The results might have implications for human service professionals in that they can contribute to a human scientific foundation in terms of understanding the persistent psychological meaning of early emotional memories as well as opening up for new venues of research on phenomena related to human memory, personality, and life-span developmental psychology.

This article reconsiders the problem of memorization in rituals in light of recent empirical work in memory research. Four hypotheses are put forward in particular: Emotionally laden details will enhance the formation of memories about any detail of the ritual; harsh sensory stimuli will function as attention-magnets, resulting in increased memorization of the stimuli at the cost of remembering other elements of the ritual; the self-relatedness of a ritual will enhance the formation of memories about the ritual, although the positive (...) effect might be limited to details that are self-related; and stress can be understood to function as a “zoom,” limiting the range of details remembered. The effects of stress will be modulated by gender differences and the timing of the ritual within the circadian cycle. The consequences of the four hypotheses are compared with the predictions of the Modes Theory and the Ritual Form Theory. (shrink)

We developed a technique to examine the effects of emotional content and context on verbal memory. Two sets of sentences were devised: in the first, each sentence was emotionally arousing due to the inclusion of an emotional “target” word. In the second set, “targets” were replaced with well-matched neutral words. Subjects read aloud a selection of emotional and neutral sentences, and were then surprised with memory tasks after a range of time delays. Emotional target words were remembered significantly better than (...) neutral words in all experiments. Recognition of emotional words was relatively stable despite increasing delays between encoding and recognition testing, in contrast to memory for neutral words, which decayed over time. Memory for neutral non-target words was enhanced when words had been presented in an emotional context. The results confirm the phenomenon of emotional enhancement of memory at short and long delays and suggest that emotional context may be encoded independently of word meaning. (shrink)
