Embodied simulation as part of affective evaluation processes: Task dependence of valence concordant EMG activity

The current studies investigated age-related biases in recall of emotion in older and younger adults. In two prospective–retrospective, Internet-based diary studies, older (aged 65 years and older) and younger participants (aged 18 to 37) reported on their affect at the end of every day. Participants then recalled their affect during the diary rating periods. In both studies, recall bias was assessed by comparing retrospective reports to the prospective diary ratings. Older adults tended to overestimate positive affect more than younger adults, who themselves tended to overestimate negative affect more than older adults, relative to diary ratings. Age-related patterns of recall bias are discussed in light of recent literature on the interface between cognition and emotion in ageing, particularly on increased positivity and reduced negativity effects in emotional processing and recall.     

SenseCam improves memory for recent events and quality of life in a patient with memory retrieval difficulties

A wearable camera that takes pictures automatically, SenseCam, was used to generate images for rehearsal, promoting consolidation and retrieval of memories for significant events in a patient with memory retrieval deficits. SenseCam images of recent events were systematically reviewed over a 2-week period. Memory for these events was assessed throughout and longer-term recall was tested up to 6 months later. A written diary control condition followed the same procedure. The SenseCam review procedure resulted in significantly more details of an event being recalled, with twice as many details recalled at 6 months follow up compared to the written diary method. Self-report measures suggested autobiographical recollection was triggered by the SenseCam condition but not by reviewing the written diary. Emotional and social wellbeing questionnaires indicated improved confidence and decreased anxiety as a result of memory rehearsal using SenseCam images. We propose that SenseCam images provide a powerful boost to autobiographical recall, with secondary benefits for quality of life.     

Remembering pride and shame: Self-enhancement and the phenomenology of autobiographical memory

People's self-images are grounded in autobiographical memories and, in particular, in the phenomenological experience associated with remembering. The desire to increase or maintain the positivity of the self-image (i.e., the self-enhancement motive) might thus play an important role in shaping memory phenomenology. This study examined this hypothesis by asking participants to recall positive and negative events that involve self-evaluations (i.e., pride and shame) and positive and negative events that involve evaluations about others (i.e., admiration and contempt); various phenomenological characteristics (e.g., sensory details, feeling of re-experiencing) were assessed using rating scales. The results show a positivity bias (i.e., subjectively remembering positive events with more details than negative events) for events that involve self-evaluations but not for events that involve evaluations of others. In addition, this bias was stronger for people high in self-esteem. It is concluded that biases affecting the phenomenology of autobiographical memory are part of the arsenal of psychological mechanisms people use to maintain a positive self-image.

Why people rehearse their memories: Frequency of use and relations to the intensity of emotions associated with autobiographical memories

People may choose to rehearse their autobiographical memories in silence or to disclose their memories with other people. This paper focuses on five types of memory rehearsal: involuntary rehearsal, rehearsal to maintain an event memory, rehearsal to re-experience the emotion of an event, rehearsal to understand an event, or rehearsal for social communication. A total of 337 participants recalled event memories, provided estimates of how often each event was rehearsed and for what reason, and rated the affective characteristics of the events. Rehearsal frequency was highest for social communication and lowest for rehearsals aimed at understanding events. For many rehearsal types, rehearsal was more frequent for positive than negative events. Frequently rehearsed events tended to show less affective fading. The pattern changed when events were socially rehearsed. For positive events, increased social rehearsal was related to a reduction in affective fading. For negative events, increased social rehearsal was associated with increased affective fading.     

Does a person selectively recall the good or the bad from their personal past? It depends on the recall target and the person’s favourability of self-views

In three studies, participants remembered real-life behaviours at Time 1 and attempted to recall them at Time 2. When the recall target was the self, a positivity bias emerged: self-positivity. In Study 3, self-positivity extended to an individual (target) who was liked by the participant, but did it not extend to a disliked target. For this latter target, a negativity bias emerged. For recall targets that were participants’ acquaintances, self-positivity in recall was also eliminated in Studies 1 and 3, and a negativity bias in recall emerged in Study 2. Finally, in Study 2 (but not Study 3), the favourability of participants’ self-view predicted the magnitude of the self-positivity in self-recall, but it did not predict valence effects in other-recall. Taken together, the results indicate that the link between behaviour valence and recall is moderated by the recall target and the favourability of one’s self-view.     

Flashbulb memories of the Paris attacks

Flashbulb memories are vivid autobiographical memories of the circumstances where an individual first learns about emotionally significant public events. Our paper assesses whether these memories were triggered by the attacks of Friday 13 November 2015 in Paris. Two hundred and ninety‐one participants answered a web‐based questionnaire that assessed their memory of the circumstances in which they first learned of the attacks. The questionnaire also assessed vividness, rehearsal, emotion, surprise and novelty. The results showed substantial and vivid recall of the context in which the participants first learned of the event. This recall was associated with fair rehearsal, negative emotional valence, surprise, and novelty. Regression analysis showed that the flashbulb recall was predicted by negative emotion. Negative emotion seems to play a key role in the formation of flashbulb memories, at least those associated with the Paris attacks.     

Valence of autobiographical memories: The role of mood, cognitive reappraisal, and suppression

The selective recall of positive memories is thought to be an effective mood repair technique, but little research has examined individual differences in the motivation or ability to implement this strategy. This study examined factors considered likely to impact valenced memory recall: dysphoria and emotion regulation strategies (i.e., cognitive reappraisal and suppression). Dysphoria was related to memory negativity but not positivity, whereas cognitive reappraisal was associated with positivity but not negativity. Suppression was not reliably related to the valence of self-reported memories, but was associated with increased accessibility of negative memories, as indicated by a response time measure. Our results indicate a relationship between cognitive reappraisal and more positive memory and suggest that the experience of dysphoria is more strongly related to negativity than positivity of memory. Our findings highlight the utility of examining emotion regulatory variables, in addition to mood, in the study of valenced memory recall, and underscore the importance of including both behavioral and self-report memory measures.     

Autobiographical memory in two older adults over a twenty-year retention interval

This article reports on a study of autobiographical memory in two older adults, wife and husband, over a retention interval of 20 years. The female participant kept a 20-year log of daily events. A sampling of events that varied in distinctiveness, from unique, one-of-a-kind events to routine, almost daily events, was used to examine cued recall using an incremental scoring system. Each event recalled was also rated on phenomenological scales of remembering versus knowing, rehearsal, and importance. The strongest effect on recall was the order of the cues, with an initial what cue, containing the content of the event, proving superior to cues containing who or where elements. When was the most effective second cue. The results demonstrate regularity in retention over time and highlighted the utility of this approach for understanding the factors that influence autobiographical memory performance.     

Memory conjunction errors for autobiographical events: more than just familiarity

Two diary studies investigated the prevalence of memory conjunction errors for real-life events. In both studies, participants completed detailed diary pages over the course of several weeks. Participants in both diary studies committed memory conjunction errors on a later recognition memory test. In the second diary study participants also made remember/know judgements. For a large proportion of their memory conjunction errors participants indicated that they "remembered" the event occurring in that context. These diary studies demonstrate that memory conjunction errors do occur for autobiographical memories, and these errors can seem compelling.     

Placing events in time: the role of autobiographical recollection

Episodic experience is argued to be rich in temporal information, but it remains unclear whether temporal information is directly coded in the event memory or is reconstructed at retrieval. The two experiments reported here emphasise the role of reconstructive processes of autobiographical context in establishing the date of memories. Younger and older participants were presented with famous public events, although only the latter had actually lived through them. Participants were asked to make forced-choice judgements about the date of the event and other event-related facts. Overall, while the older group showed better fact knowledge of the events, this did not translate into better dating performance. This older group showed similar dating performance across events with high and low factual knowledge. In contrast, the younger group's dating accuracy was determined by their level of knowledge. This suggests that older individuals who have direct episodic experience of an event may perform the task in a qualitatively different manner, eschewing semantic facts in favour of other sources of information. Crucially, this process does not appear to enhance performance. A second experiment addressed the issue of whether older participants date events based on general qualities of the event memory (e.g., vividness), the availability of other event-related semantic facts, or autobiographical context. It was found that the ability to place an event in autobiographical context is related to dating accuracy, but not to other aspects of memory.

What happens if you retest autobiographical memory 10 years on?

Burt (1992a, 1992b) reported data on the autobiographical memory of diarists for events that had occurred on average 3.3 years earlier. This paper reports data on 11 of the diarists, who were recontacted after a further 10 years and who agreed to a retest of their memory. Estimates of event date and event duration from the two recall attempts were compared. As predicted, duration estimation was extremely stable and showed no detrimental effects of the additional 10 years of retention interval. Estimation of event date was predicted to show an increase in forward telescoping due to the increased remoteness of the event sample, but, contrary to this prediction, backward telescoping dominated dating errors. A combination of the establishment of a recent boundary and Kemp's (1999) associative model of dating is proposed as an explanation for these results. It is argued that the nature of dating errors may depend on the time of the event's occurrence in the life span and the age of the individual dating the events.

An exploration of the relationship among valence,fading affect,rehearsal frequency,and memory vividness for past personal events

The affect associated with negative (or unpleasant) memories typically tends to fade faster than the affect associated with positive (or pleasant) memories, a phenomenon called the fading affect bias (FAB). We conducted a study to explore the mechanisms related to the FAB. A retrospective recall procedure was used to obtain three self-report measures (memory vividness, rehearsal frequency, affective fading) for both positive events and negative events. Affect for positive events faded less than affect for negative events, and positive events were recalled more vividly than negative events. The perceived vividness of an event (memory vividness) and the extent to which an event has been rehearsed (rehearsal frequency) were explored as possible mediators of the relation between event valence and affect fading. Additional models conceived of affect fading and rehearsal frequency as contributors to a memory’s vividness. Results suggested that memory vividness was a plausible mediator of the relation between an event’s valence and affect fading. Rehearsal frequency was also a plausible mediator of this relation, but only via its effects on memory vividness. Additional modelling results suggested that affect fading and rehearsal frequency were both plausible mediators of the relation between an event’s valence and the event’s rated memory vividness.     

Remembering the past and imagining the future: A role for nonvisual imagery in the everyday cognition of blind and sighted people

Past research has associated depression with memory biases pertaining to the frequency, duration, and specificity of past events. Associations have been proposed between both negative and positive memory biases and depression symptoms. However, research has not examined the occurrence of actual events over time in the study of memory bias. To address these limitations and investigate whether a negative or positive memory bias is associated with symptoms of depression, we collected weekly data on specific types of life events over a 4-year period from a sample of college students, and asked students to recall event frequency at the end of that period. Exaggerated recall of frequency for positive events but not other types of events was associated with depression symptoms, using both continuous and categorical measures. Moderator analyses indicated that these effects were evidenced primarily for memories involving the self and among individuals low in trait self-enhancement. The current study indicates that positive memory-frequency bias is an important type of memory bias associated with symptoms of depression. Results support the idea that the link between memory bias for positive event frequency and depressed mood arises out of a current-self vs past-self comparison.
