Memory of pain induced by physical exercise

The aim of this study was to assess the memory of pain induced by running a marathon and the factors that influence it. Sixty-two marathon runners participated in the study, which comprised two phases. Immediately after a participant had reached the finishing line of the marathon, they were asked to rate the intensity and the unpleasantness of their pain and the emotions they felt at that time. Either three or six months later they were asked again to rate the intensity and the unpleasantness of the same pain experience. Regardless of the length of recall delay, participants underestimated both recalled pain intensity and unpleasantness. The pain and negative affect reported at the time of the pain experience accounted for 24% of the total variance in predicting recalled pain intensity and 22% of the total variance in predicting recalled pain unpleasantness. Positive affect at the time of pain experience was not a significant predictor of both the recalled pain intensity and pain unpleasantness. It is concluded that pain induced by physical exercise is not remembered accurately and the pain and negative affect experienced influence recall. Further research is needed on the influence of positive affect on the memory of pain.     

Cannabis-associated impairments in the fading affect bias and autobiographical memory specificity

We investigated potential relationships between cannabis use and 2 phenomena associated with autobiographical remembering: the fading affect bias (FAB) and memory specificity. The FAB is an emotional affect regulation mechanism that is observed when the intensity of affect associated with experiencing negative memories fades faster than the intensity of affect associated with experiencing positive memories. Memory specificity refers to the level of detail with which events are recalled. No studies have examined the relationships between cannabis use, the FAB, and memory specificity simultaneously. Chronic cannabis users (N = 47) and non-users (N = 52) recalled and described positive and negative autobiographical events and rated the affective intensity for the events at the time of occurrence and at time of test. Participants retrieved additional memories using a sentence-completion recall task, which were coded for specificity. Cannabis users showed reduced fading affect for unpleasant events and reduced memory specificity compared to non-users.     

Anxiety and Mood-congruent Autobiographical Memory: A Conceptual Failure to Replicate

This study further explored whether highly anxious participants exhibit a mood-congruent autobiographical memory bias, as was found in two previous studies (Burke & Mathews, 1992; Richards & Whittaker, 1990). The 74 high and low trait anxious participants retrieved personal memories to anxiety-related, neutral, and positive cue words, and were then asked to recall the original cue words. The study also explored how expression of emotional versus factual responses might affect a memory bias. On most dependent measures, no differences were found between anxiety groups. However, low anxious participants recalled more memories overall than high anxious participants. In addition, the emotions groups recalled more words at free recall than the facts groups. Findings fail to support previous studies that found an autobiographical memory bias to be associated with high anxiety, and cast more support for the mounting evidence against a mood-congruent memory bias in anxiety.     

Positive memory enhancement training for individuals with major depressive disorder

When in a negative mood state, individuals with major depressive disorder (MDD) may have difficulties recalling positive autobiographical memories in a manner that repairs that negative mood. Using cognitive bias modification techniques, investigators have successfully altered different aspects of cognition among individuals with MDD. However, little has been done to investigate the modification of positive autobiographical memory recall. This study examined the impact of a novel positive memory enhancement training (PMET) on the memories and subjective affective experiences of individuals with MDD (N = 27). Across a series of trials, participants first recalled a sad memory to elicit a negative mood state. They then recalled a happy memory and completed procedures to elicit a vivid, here-and-now quality of the memory. PMET procedures were hypothesized to promote mood repair via the recall of increasingly vivid and specific positive memories. PMET participants demonstrated improved memory specificity and greater perceived ability to “relive” positive memories. The procedures also repaired mood; PMET participants’ affect following recall of positive memories did not differ from control participants’ affect following recall of neutral memories. Results provide preliminary support for PMET as a method to improve the quality of positive memories and facilitate emotion regulation in MDD.     

Mood Regulation and Memory: Repairing Sad Moods with Happy Memories

A total of 106 undergraduates participated in a study examining how individuals retrieve memories to repair negative moods. Participants first completed a measure of depression. Two weeks later, participants were assigned to either a sad or neutral mood induction. After mood induction, they recalled two memories, rated their affective responses to the memories, and indicated why they chose the valence and order of the memories. Consistent with mood-congruent recall, participants in the sad condition reported sadder memories than those in the neutral condition. However, participants with prior low depression scores tended to recall more positive second memories, whereas participants with higher prior depression scores recalled consecutive negative memories. Sixty-eight per cent of sad participants who retrieved a negative first and positive second memory mentioned mood repair as motivating the recruitment of the more positive second memory.     

Trait anxiety, trait depression, worry, and memory

A study is reported which investigated the proposal that high trait anxiety is associated with a memory bias for worry themes. Forty-five participants were categorised as being high or low trait anxious on the basis of scores on the (Spielberger et al., 1983) (Manual for the State-Trait Anxiety Inventory (Form Y) (1983)). The participants were requested to rate a number of worry and non-worry statements for how much they generally thought about the issues represented by them. Analysis of the ratings given by the participants showed that low trait anxiety individuals thought about the non-worry items significantly more than worry items. The high trait anxiety participants, however, showed little or no difference in the amount of time spent thinking about worry and non-worry themes. In a subsequent free recall task of the statements it was observed that the low trait anxiety group recalled significantly more non-worry than worry items, whereas there was no such difference for the high trait group. It was also found that the degree of memory bias was related to both positive affectivity and trait anxiety. The implications of such findings are discussed.     

Effects of self-complexity on mood-incongruent recall

Some people cope with negative moods by retrieving positive memories, which is mood-incongruent recall. Though mood-incongruent recall is helpful for mood-regulation, the factors that influence people's ability to utilize mood-incongruent recall are not well understood. This study investigated whether complex knowledge structure is a factor for the ability of mood-incongruent recall, based on self-complexity. In the experiment, 50 participants were requested to recall positive memories in both neutral and negative moods. The results of this study indicated that self-complexity was an important factor associated with participants' ability to recall positive memories while they were in negative moods. Participants who rated high in self-complexity were those whose knowledge is structured in a complex way, recalled more highly positive memories in negative moods than in neutral moods. On the other hand, participants who were rated low in self-complexity with simple knowledge structures recalled memories with a lower extent of positivity in negative moods than those in neutral moods.     

Mood and recall of autobiographical memory: the effect of focus of self-knowledge

Mood state facilitates recall of affectively congruent memories (i.e., mood-congruent recall). Mood state may also promote motivation to alleviate a negative affective state, leading to retrieval of affectively incongruent memories (i.e., mood incongruent recall). The present study demonstrates that the focus of self-knowledge influences the occurrence of both mood-congruent recall and mood-incongruent recall. Three experiments found that mood-congruent recall occurred when participants recalled their experiences from a self-aspect that was related to the elicitor of moods, whereas mood-incongruent recall occurred when they recalled their experiences from a self-aspect that was unrelated to the elicitor of moods. These results suggest that the nature of the self-aspect from which persons recall their experiences determines whether mood-congruent or mood-incongruent recall occurs.     

Trait anxiety, working memory capacity, and the effectiveness of memory suppression

We aimed at replicating the finding that humans are able to suppress unwanted memories, and tested whether this ability varies with individual differences in working memory capacity, trait anxiety and defensiveness. In a think/no-think experiment, participants either recalled or suppressed previously learned words for 0, 8 or 16 times. Suppression did not have an overall detrimental effect on later recall performance. However, higher recall rates after repeated suppression were exclusively predicted by higher trait anxiety. These results are discussed in relation to current theories on anxiety and executive control.     

The Role of the Listener on the Emotional Valence of Personal Memories in Emerging Adulthood

Many scholars stressed the role of social interactions in the construction of autobiographical memories, especially in late adolescence and emerging adulthood. This paper aims to assess the impact of the listener attitude on narrator’s emotional valence of past life events concerning the end of a close relationship. 157 emerging adults have been asked to recall a memory and to randomly narrate it to a listener previously trained to be distracted and detached (DL group) versus attentive and empathic (AL group). A control group (CG) had only to reflect internally on the recalled memory. Participants had to allocate one or more emotions to their memory from a 12-item list in a recall task, a narrative/reflection task and a 15-day recall follow-up. The percentages of negative, positive and neutral emotions were assessed and changes among the three emotional allocations were measured. Results showed that participants of the AL group after the narrative task increased the positive emotional engagement of memories and decreased the negative emotions in comparison to DL participants and the CG ones. The authors interpret the results suggesting that narrating autobiographical memories to attentive peers is a way to co-construct their emotional meaning and discuss findings in the light of the knowledge on the lifespan period of emerging adulthood.     

Abstract recall of a happy memory to repair sad mood in dysphoria: A possible link to negative cognition

The capacity to repair sad mood through the deliberate recall of happy memories has been found to be impaired in dysphoric individuals. Rumination, or adopting an abstract processing mode, has been proposed as a possible mechanism underpinning this effect. In low and high dysphoric participants, we examined the relative consequences of adopting an abstract or concrete processing mode during happy memory recall or engaging in distraction for (1) mood repair and (2) cognitive content. Recalling a happy memory in either an abstract or concrete way resulted in greater happiness than distraction. Engaging in abstract recall of a happy memory resulted in high dysphoric participants generating negative evaluations and negative generalisations. These findings raise the interesting possibility that abstract processing of positive memories has the potential to generate negative cognition.     

Mood repair and processing mode in depression

Recalling positive autobiographical memories is a powerful emotion regulation strategy that can be used to repair low mood and alleviate negative affect. Unlike healthy individuals, those with current or past depression do not experience an improvement in mood as a consequence of recalling positive memories. We tested whether differences in processing mode might account for this impairment. Following mood induction procedures designed to ensure equivalence of mood state, depressed (n = 35) and recovered depressed (n = 33) participants were instructed to recall a positive memory and focus on it while adopting either an abstract or a concrete mode of processing. Participants in the abstract processing condition experienced no change in mood, while those in the concrete processing condition showed improved mood after memory recall. This research illustrates that the process by which positive autobiographical memories are recalled is important in determining their emotional impact and suggests that psychological interventions for depression may be improved by explicitly targeting processing mode.     

Continulty in the Life Story: Self-Defining Memories, Affect, and Approach/Avoidance Personal Strivings

To study affective responses to memories and their relationship to personal strivings, 117 participants (65 males, 52 females) wrote selfdefining memories and indicated their affective responses to the memories. A week later they generated personal strivings, rated them along 10 dimensions, and indicated the relevance of their memories to the strivings. Participants who recalled more memories relevant to the attainment of their strivings felt more positively about their memories. Additionally, participants who listed greater percentages of avoidance strivings also recalled more memories related to the nonattainment of their strivings. Participants with higher percentages of avoidance strivings also recalled less positive memories. In an extension of Emmons's (1986) research, participants' feelings about personal strivings were linked to their affective responses to memories generated a week earlier. These results support a goal-based theory of affect and a role for motivation in memory.     

Emotion and vantage point in autobiographical

Autobiographical memories may be recalled from two different perspectives: Field memories in which the person seems to remember the scene from his/her original point of view and observer memories in which the rememberer sees him/herself in the memory image. Here, 122 undergraduates participated in an experiment examining the relation between field vs. observer perspective in memory for 10 different emotional states, including both positive and negative emotions and emotions associated with high vs. low intensity. Observer perspective was associated with reduced sensory and emotional reliving across all emotions. This effect was observed for naturally occurring memory perspective and when participants were instructed to change their perspective from field to observer, but not when participants were instructed to change perspective from observer to field.     

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.     

Assessing the specificity of autobiographical memory in individuals at a trait-based vulnerability to bipolar disorder using a sentence completion task

Overgeneral autobiographical memory recall has been associated with the diagnosis of bipolar disorder, but the role of overgenerality in the vulnerability to bipolar disorder remains under-researched. While a previous study suggested that high-risk individuals for bipolar disorder recall emotionally negative memories in specific detail, this is in contrast to memory recall patterns noted in bipolar samples. The Autobiographical Memory Test (AMT) used in previous non-clinical studies has also been criticised for not being sensitive to overgenerality due to its repetition of specificity instructions and practice trials. The traditional AMT format may allow some individuals to override their trait-based tendencies to be overgeneral. The current study used a sentence completion task to assess memory specificity in groups of students at a low and high trait-based vulnerability for bipolar disorder. In contrast to previous research, high-risk individuals recalled fewer specific positive memories and greater numbers of overgeneral negative memories than low-risk individuals. These results support the notion that the vulnerability for bipolar disorder might be associated with similar recall biases as demonstrated in bipolar samples, and that the AMT might not be sufficiently sensitive to detect overgenerality in non-clinical groups. The implications of these findings and directions for future research are discussed.     

The valence and the functions of autobiographical memories: Does intensity matter?

Autobiographical memories serve psychosocial functions in daily life and the use of memories is related to their valence. In the present study, we examined whether functions are also related to the intensity of positive and negative memories. Our sample included 110 participants (57–89 years of age). Memories were prompted with 30 emotionally neutral cue words. Participants rated the emotional quality of each memory and indicated how frequently they had recalled it for self-continuity, directing behavior, social-bonding, and mood-enhancement. We used multilevel modeling to test whether individual differences in the use of memories can explain why individuals recall different numbers of positive and negative memories as well as memories high or low in intensity. Each function revealed its specific pattern regarding valence and intensity but also regarding within-person and between-person effects. Mood-enhancement showed the strongest relations, which points to the importance of considering emotion regulation as a function of autobiographical memory.
