Comparing two perceived characteristics of autobiographical memory: Memory detail and accessibility

Four samples of participants recalled autobiographical memories. While some evidence emerged from regression analyses suggesting that judgements of the amount of detail contained in each memory and judgements of the ease with which events could be recalled were partially independent, the analyses generally showed that these judgements were similarly predicted by various event characteristics (age, typicality, self-importance, emotional intensity at event occurrence, rehearsal types). Co-occurrence frequency data yielded similar conclusions, showing that while ease ratings and detail ratings occasionally diverged, they were more often consistent with each other. Finally, the data also suggested that events that prompted emotional ambivalence were not judged to be more easily recalled, or to contain more detail, than non-ambivalent events.     

What characterizes life story memories? A diary study of Freshmen’s first term

We investigated whether memories are selected for the life story based on event characteristics. Sixty-one students completed weekly diaries over their first term at university. They described, dated and rated two events each week. Three months after the end of the term they completed an unexpected memory test. They recalled three memories from the diary period that were important to their life story. Three randomly selected events scoring low on importance to the life story functioned as control memories. Life story memories were rated higher on goal relevance, emotional intensity, importance and rehearsal in the diary and maintained their higher ratings at the test session, while ratings for control memories dropped off. Life story memories' content was less consistent over time but they were more accurately dated than control memories. The results suggest that event characteristics play an important role for the selection of life story memories.     

Phenomenal characteristics associated with real and imagined events: the effects of event valence and absorption

This study examined the effects of emotional valence of an event and individual differences in absorption on the phenomenal characteristics associated with real and imagined events. Each participant described four events. Two of these were real and two were imagined, with one pleasant and stressful event being generated for each category. Pleasant events (both real and imagined) contained more detail (visual detail, smell, and taste, and more information regarding location, time, etc.) than stressful events. In addition, higher levels of absorption were related to higher ratings for both real and imagined events (for both pleasant and stressful events). Discussion focused on implications for further research in source monitoring and other relevant domains. Copyright © 1999 John Wiley & Sons, Ltd.     

Collective memories of three wars in United States history in younger and older adults

A collective memory is a representation of the past that is shared by members of a group. We investigated similarities and differences in the collective memories of younger and older adults for three major wars in U.S. history (the Civil War, World War II, and the Iraq War). Both groups were alive during the recent Iraq War, but only the older subjects were alive during World War II, and both groups learned about the Civil War from historical sources. Subjects recalled the 10 most important events that occurred during each war and then evaluated the emotional valence, the relative importance, and their level of knowledge for each event. They also estimated the percentage of people that would share their memory of each event within their age group and the other age group. Although most historical events were recalled by fewer than 25 % of subjects, younger and older adults commonly recalled a core set of events for each war that conform to a narrative structure that may be fundamental to collective remembering. Younger adults showed greater consensus in the events that they recalled for all three wars, relative to older adults, but there was less consensus in both groups for the Iraq War. Whereas younger adults recalled more specific events of short duration, older adults recalled more extended and summarized events of long duration. Our study shows that collective memories can be studied empirically and can differ depending on whether the events are experienced personally or learned from historical sources.     

Adult attachment and memory of emotional reactions to negative and positive events

Relations between adult attachment and memory for earlier emotional reactions to negative and positive events were examined. Hypotheses were that avoidance would be associated with underestimating earlier negative affect, whereas anxiety would be associated with overestimating earlier negative affect. Also, both avoidance and anxiety were expected to relate to underestimating earlier positive affect intensity. Participants (119 college students) completed daily report forms three times a day for 4 days on which they described and rated their immediate emotional reactions to events within each time period. Approximately 10 days later, they were asked to estimate their immediate emotional reaction to one negative event and one positive event. Events were coded as interpersonal or non-interpersonal. Contrary to hypotheses, for those lower on avoidance, anxiety related to lower levels of recalled negative affect (i.e., greater underestimation) for negative interpersonal events. As expected, with positive events, anxiety and avoidance related to lower levels of recalled positive emotions. Results suggest that memory processes could be one explanation of how working models operate and are sustained over time.     

More than a feeling: Emotional cues impact the access and experience of autobiographical memories

Remembering is impacted by several factors of retrieval, including the emotional content of a memory cue. Here we tested how musical retrieval cues that differed on two dimensions of emotion—valence (positive and negative) and arousal (high and low)—impacted the following aspects of autobiographical memory recall: the response time to access a past personal event, the experience of remembering (ratings of memory vividness), the emotional content of a cued memory (ratings of event arousal and valence), and the type of event recalled (ratings of event energy, socialness, and uniqueness). We further explored how cue presentation affected autobiographical memory retrieval by administering cues of similar arousal and valence levels in a blocked fashion to one half of the tested participants, and randomly to the other half. We report three main findings. First, memories were accessed most quickly in response to musical cues that were highly arousing and positive in emotion. Second, we observed a relation between a cue and the elicited memory’s emotional valence but not arousal; however, both the cue valence and arousal related to the nature of the recalled event. Specifically, high cue arousal led to lower memory vividness and uniqueness ratings, but cues with both high arousal and positive valence were associated with memories rated as more social and energetic. Finally, cue presentation impacted both how quickly and specifically memories were accessed and how cue valence affected the memory vividness ratings. The implications of these findings for views of how emotion directs the access to memories and the experience of remembering are discussed.     

Memory for media: investigation of false memories for negatively and positively charged public events

Despite a large body of false memory research, little has addressed the potential influence of an event's emotional content on susceptibility to false recollections. The Paradoxical Negative Emotion (PNE) hypothesis predicts that negative emotion generally facilitates memory but also heightens susceptibility to false memories. Participants were asked whether they could recall 20 "widely publicised" public events (half fictitious) ranging in emotional valence, with or without visual cues. Participants recalled a greater number of true negative events (M=3.31/5) than true positive (M=2.61/5) events. Nearly everyone (95%) came to recall at least one false event (M=2.15 false events recalled). Further, more than twice as many participants recalled any false negative (90%) compared to false positive (41.7%) events. Negative events, in general, were associated with more detailed memories and false negative event memories were more detailed than false positive event memories. Higher dissociation scores were associated with false recollections of negative events, specifically.     

Emotion, memory, and attention in the taboo Stroop paradigm

This study tested the binding hypothesis: that emotional reactions trigger binding mechanisms that link an emotional event to salient contextual features such as event location, a frequently recalled aspect of naturally occurring flash-bulb memories. Our emotional events were taboo words in a Stroop color-naming task, and event location was manipulated by presenting the words in different task-irrelevant screen locations. Seventy-two participants named the font color of taboo and neutral words, with instructions to ignore word meaning; in one condition, several words were location consistent (i.e., always occupied the same screen location), whereas in another condition, several colors were location consistent. Then, in a surprise recognition memory test, participants recalled the locations of location-consistent words or colors. Although attention enhanced overall location memory for colors (the attended dimension during color naming), emotion (taboo vs. neutral words) enhanced location memory for words but not colors. These results support the binding hypothesis but contradict the hypothesis that emotional events induce image-like memories more often than non-emotional events.     

Closure of autobiographical memories: The effects of written recounting from first- or third-person visual perspective

Autobiographical memories are recalled with varying degrees of psychological closure. Closure is a subjective assessment of how far a remembered experience feels resolved, and it has been suggested that one predictor of closure is the amount of emotional detail in the memory. Study 1 examined which aspect of emotional detail is important for closure, and showed that open and closed negative memories were distinguished by ratings of emotion evoked during recall, not by remembered emotion from the time of the event. The recall of open memories was accompanied by more intense, more negative, and less positive emotion than the recall of closed memories. Biased retelling of memories has been shown to influence closure and on the basis of evidence that third-person recall serves a distancing function, Study 2 examined whether instructions to repeatedly recount an open memory from a third-person perspective would increase closure compared with a single or repeated recounting from a first-person perspective. While repeated third-person recounting had the greatest influence on closure, there were also increases in the first-person recounting groups. The results suggest that closure can be increased by reporting memories in written narrative form, particularly if repeatedly expressed from the third-person perspective.

The enduring effect of availability

The present study addressed whether experienced ease of retrieval of autobiographical events affects trait judgments made immediately and after a delay (Experiment 1) and whether this influence is modulated by either of two discounting instructions (Experiment 2). In Experiment 1, participants first attempted to retrieve 6 or 12 personal memories for different traits and then made ease of retrieval and self-trait judgments immediately or 1 week later. In Experiment 2, participants made immediate ratings and then delayed ratings under 3 instructional manipulations: a generic instruction to repeat these judgments, to make these ratings after they were reminded of their original recall total, or to make these ratings after they had their retrieval ease discounted or augmented. In each experiment, an enduring effect of availability was obtained in that the relationship between ease of retrieval and self-trait rating was only slightly affected by the delay. Being reminded of the original number of recalled memories nullified the relationship between ease of retrieval and trait rating. However, discounting or augmenting ease of retrieval, which altered ease of retrieval ratings, did not. Potential explanations for an enduring effect of availability are discussed.     

Emotional discussions reduce memory recall

People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses’ discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.     

Dimensions and determinants of judgements of colour samples and a simulated interior space by architects and non-architects.

Architects and non-architects made Semantic Differential ratings of colour samples (chips) and a simulated interior space (a model). In analyses of the total samples' ratings (architects and non-architects) of (a) colour chips and (b) models, and individual sample analyses, (c) architects' chip judgements, (d) architects' model judgements, (e) non-architects' chip judgements, and (f) non-architects' model judgements, five factors occurred, though not necessarily all in any one analysis. These were: (i) dynamism; (ii) spatial quality; (iii) emotional tone; (iv) evaluation; (v) complexity. Linear correlations between parameters of the Munsell Color System and the above factors in the various analyses were calculated, while parallel analyses were carried out employing a graphical technique described by Sivik (1974a) involving isosemantic maps. In all analyses, linear correlations between the colour parameters and judgements were found for the dynamism factor, spatial quality factor, and emotional tone factor. They were associated respectively with chroma, value, and hue. Inspection of the isosemantic maps indicated subsidiary effects of the non-dominant dimensions of a non-linear sort, though the maps also exhibited the linear relations. Linear correlations were low or non-existent for the evaluation and complexity factors, and the complex nature of their determinants was clear from the isosemantic maps. The dterminants of judgements were similar for architects and non-architects, with the exception of evaluative judgements for the models in which markedly different determinants were noted. Comparability of the present findings with other studies carried out in a variety of countries over a 20 year period was high for dynamism, spatial quality, and emotional tone, and it is suggested that there may be something inherent in the response to colour in relation to such judgements. Recent physiological work is discussed, and its limitations in terms of colours sampled and an overconcentration on the hue dimension noted. In contrast, it is suggested that dimensions of judgement, such as evaluation or complexity, reflect to a greater extent culture or training, and are hence independent of the basic colour attributes.     

Daily experiences and well-being: Do memories of events matter?

Retrospective subjective well-being (SWB) refers to self-reported satisfaction and emotional experience over the past few weeks or months. Two studies investigated the mechanisms linking daily experiences to retrospective SWB. Participants reported events each day for 21 days (Study 1) or twice a week for two months (Study 2). The emotional intensity of each event was rated: (1) when it had recently occurred (proximal intensity); and (2) at the end of the event-reporting period (distal intensity). Both sets of ratings were then aggregated across events and used to predict retrospective SWB at the end of the study. Path analyses showed that proximal intensity predicted retrospective SWB whereas distal intensity did not. The effect remained even after controlling for trait happiness and neuroticism. These results suggest that daily experiences influence retrospective SWB primarily through abstract representations of the past few weeks or months (as measured by aggregated proximal intensity ratings) rather than the explicit recollection of individual events during the same period (as measured by aggregated distal intensity ratings). Retrospective SWB, in turn, mediated the effect of daily experiences on global SWB (i.e., self-reported satisfaction and emotional experiences in general).     

All in the mind's eye? Anger rumination and reappraisal

Research on rumination has demonstrated that compared with distraction, rumination intensifies and prolongs negative emotion. However, rumination and distraction differ both in what one thinks about and how one thinks about it. Do the negative outcomes of rumination result from how people think about negative events or simply that they think about them at all? To address this question, participants in 2 studies recalled a recent anger-provoking event and then thought about it in 1 of 2 ways: by ruminating or by reappraising. The authors examined the impact of these strategies on subsequent ratings of anger experience (Study 1) as well as on perseverative thinking and physiological responding over time (Study 2). Relative to reappraisal, rumination led to greater anger experience, more cognitive perseveration, and greater sympathetic nervous system activation. These findings provide compelling new evidence that how one thinks about an emotional event can shape the emotional response one has.     

Memory for events after twenty years

This is a study of one person's memory for events that occurred twenty years earlier. Memory was observed to follow an asymptotic rate of decay. No experience of recovered memories occurred. Factors found to be related to recall were the rarity of the event, its vividness, and the emotional intensity experienced at the time. Factors unrelated or only weakly related were perceived importance of the event, its association with knowledge, and intensities of physical sensations. Pleasant events were recalled a little better than unpleasant. Though less strongly associated with memory than is location, moderate marking of events with date and time was found. The results suggest that personal memory declines as the images of events one by one submerge into the mass of generalized experiences. The more vivid, rare, and emotional experiences are more likely to remain discriminable, and may be sustained by rehearsal. Copyright © 2002 John Wiley & Sons, Ltd.     

Regulatory focus and affective recall

In two studies, we tested the impact of regulatory focus on recalled affect for past academic outcomes. Because promotion focus concerns achieving gains, it should be related to greater recalled positive affect. In contrast, prevention focus concerns avoiding losses, and should be related to greater recalled negative affect. In Study 1, promotion focus led to greater recalled positive affect for positive events, while prevention focus led to greater recalled negative affect regardless of event valence. In Study 2, promotion focus increased recalled positive affect for both positive and negative events, whereas prevention focus increased recalled negative affect for both positive and negative events. These studies demonstrate that current motivation can alter memory for past affective experiences; the regulatory focus ascribed to a previous event changes the extent to which people remember their emotional experience. Implications are discussed.     

Children as Earwitnesses: Memory for Emotional Auditory Events

We examined the influence of age and emotionality of auditory stimuli on long‐term memory for environmental sound events. Sixty children aged 7–11 years were presented with two environmental sound events: an emotional car crash and a neutral event, someone brushing their teeth. The sound events comprised six individual environmental sounds, and the participants passively listened to the sound events through a headset. After a two‐week delay, participants performed a cued recall task and a recognition task. Independent of age, children were notably poor at recalling the sound events. Children recalled and recognized significantly more sounds from the emotional sound event than the neutral sound event. Additionally, the older children performed the recall task better than the younger children. The present findings confirm and expand the previously reported superiority of emotional material in memory.Copyright © 2016 John Wiley & Sons, Ltd.     

The fading affect bias: Effects of social disclosure to an interactive versus non-responsive listener

The intensity of negative emotions associated with event memories fades to a greater extent over time than positive emotions (fading affect bias or FAB). In this study, we examine how the presence and behaviour of a listener during social disclosure influences the FAB and the linguistic characteristics of event narratives. Participants recalled pleasant and unpleasant events and rated each event for its emotional intensity. Recalled events were then allocated to one of three experimental conditions: no disclosure, private verbal disclosure without a listener or social disclosure to another participant whose behaviour was experimentally manipulated. Participants again rated the emotional intensity of the events immediately after these manipulations and after a one-week delay. Verbal disclosure alone was not sufficient to enhance the FAB. However, social disclosure increased positive emotional intensity, regardless of the behaviour of the listener. Whilst talking to an interactive listener led unpleasant event memories to decrease in emotional intensity, talking to a non-responsive listener increased their negative emotional intensity. Further, listener behaviour influenced the extent of emotional expression in written event narratives. This study provides original evidence that listener behaviour during social disclosure is an important factor in the effects of social disclosure in the FAB.
