Cognitive resources, valence, and memory retrieval of emotional events in older adults.

In 2 studies with older adults, the authors investigated the effect of executive attention resources on the retrieval of emotional public events. Participants completed a battery of working memory tasks, as a measure of executive attention, and a battery of tasks assessing memory, as well as subjective experiences associated with the retrieval of remote public events. Participants also rated the valence of each public event story. The group-rated valence of the public event stories predicted retrieval and the quality of experiences associated with them, such that emotionally arousing events elicited the highest memory rates and the richest experiences. Furthermore, positive public events elicited the highest memory rates. Executive attention moderated only the relationship between event valence and how participants' associated memories are experienced at retrieval, such that superior executive attention resources predicted richer experiences associated with positive relative to neutral and negative stories. The current results extend previous findings on the effects of aging on emotion regulation, suggesting that cognitive control resources modulate subjective experiences associated with retrieved memories for remote real life events, but not memory retrieval itself.

Gender differences in autobiographical memory for childhood emotional experiences.

Research to date has paid remarkably little heed to gender differences in autobiographical memory. To redress this, the author examined memory for childhood events in adult men and women remembering back to childhood, and in children themselves. Five studies were conducted, and results revealed that females consistently recalled more childhood memories than males did and were generally faster in accessing the memories recalled. Furthermore, the gender difference observed was specific to memories of events associated with emotion and was apparent across a diverse range of emotions experienced by both the self and others. The overall pattern of findings obtained is consistent with the proposition that gender-differentiated socialization processes influence the content and complexity of representations of autobiographical emotional events in memory. To some extent, then, autobiographical memory appears to be a socially constructed phenomenon. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Directed forgetting of recently recalled autobiographical memories.

In 6 experiments, the authors investigated list-method directed forgetting of recently recalled autobiographical memories. Reliable directed forgetting effects were observed across all experiments. In 4 experiments, the authors examined the impact of memory valence on directed forgetting. The forget instruction impaired recall of negative, positive, and neutral memories equally, although overall, participants recalled fewer unemotional memories than emotional memories. The preexisting organization of memories enhanced the directed forgetting effect, and a release from forgetting occurred only when the forgotten memories were directly cued. The authors discuss the roles of emotion, retrieval dynamics, and organization in these effects and suggest that the directed forgetting of recently recalled autobiographical memories may reflect the inhibition of recently formed memories of remembering, that is, episodic inhibition. The authors consider the implications of these findings for the control of autobiographical remembering in everyday life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neurobiology of reconstructed memory.

The authors present evidence that normal autobiographical memories and "recovered" autobiographical memories of long-forgotten traumatic events are produced by the same mechanisms. The basic process involves the parallel storage of information in a set of independent modules, the selective retrieval and reaggregation of this dispersed information within an appropriate spatiotemporal context, and the organization of this aggregate by a narrative. The result is a seamless blend of retrieved information (that which is recalled) and knowledge (that which is inferred) experienced as an autobiographical memory. The critical difference between normal and recovered memories, by this account, is the impact of trauma on the storage process: The physiological consequences of trauma can include a disabling of the neural module responsible for encoding the appropriate spatiotemporal context. Recovered memory involves retrieval of memory fragments, confabulation (innocent or not) driven by inference, and the fitting of a context to this incomplete aggregate. This too is experienced as an autobiographical memory. The implications of this view for estimating the veridicality of recovered memories are discussed.

Autobiographical memory in suicide attempters.

Examined both hedonic and nonhedonic aspects of autobiographical memory in 25 patients (mean age 31 yrs) who had recently attempted suicide by overdose, 25 hospital patients (clinical nonoverdose controls), and 25 Ss recruited from the authors' S panel (panel controls). Ss completed the Profile of Mood States, an autobiographical memory test, and semantic memory tasks. Results indicate that attempted-suicide Ss, who were required to retrieve specific personal memories to positive or negative cue words, showed biased retrieval when their performance was compared with that of control groups, but the bias was due to delayed retrieval of positive memories rather than to speeded retrieval of negative memories. At least part of this effect was due to inappropriate retrieval strategies that yielded general, rather than specific, memories in the overdose group, a finding that may have implications for associative network models of emotional memory.

Reactivation, interference, and reconsolidation: Are recent and remote memories likewise susceptible?

The retrieval of a consolidated, apparently stable memory can return it to a labile state, necessitating another period of stabilization, termed reconsolidation. During reconsolidation, memories are susceptible to modifications, thus providing the opportunity to change unwanted memories. In a test of whether the possibility to alter retrieved memories depends on the age of the memories, participants learned a set of emotional and neutral pictures and recalled it 1, 7, or 28 days later. Immediately after retrieval, participants learned a second set of pictures. Memory retrieval per se enhanced 28-day-old memories but had no effect on 1-day- or 7-day-old memories. Learning new pictures interfered with 1-day-old and 28-day-old memories but not with 7-day-old memories. Evidence for reconsolidation effects was generally rather weak and at most present for 7-day-old memories. These findings show that retrieval and interference have opposite effects on memory that depend on the remoteness of the memories and raise the question under which conditions reconsolidation effects occur in human memory.

Self-guides and emotionally significant childhood memories: A study of retrieval efficiency and incidental negative emotional content.

Two studies examined the effects of several cue types on ease of retrieval (EOR) and incidental negative emotional content (INEC) of childhood memories. Ss were presented an individually tailored list of cues and verbalized the 1st memory of a childhood experience that came to mind. Both studies included self-guide cues (trait attributes representing accessible, emotionally significant self-evaluative standards), affect cues (positive and negative emotion labels), and yoked-control cues (self-guide cues of other Ss). In Study 1, both EOR and proportion of INEC varied by cue type; negative affect cues led to the most efficient retrieval and most negative content, whereas self-guide cues (especially self-discrepant cues) showed greater EOR and INEC than control cues. Study 2 included 2 additional self-referential cue types (TAT and self-rating checklist) to examine the influences of self-referentiality and affectivity on the dependent measures. Negative affect and self-guide cues were again associated with greater EOR and greater INEC. Both negative emotionality and self-evaluative significance appear to influence retrieval of emotionally significant childhood memories.

Becoming a better person: Temporal remoteness biases autobiographical memories for moral events.

Our autobiographical self depends on the differential recollection of our personal past, notably including memories of morally laden events. Whereas both emotion and temporal recency are well known to influence memory, very little is known about how we remember moral events, and in particular about the distribution in time of memories for events that were blameworthy or praiseworthy. To investigate this issue in detail, we collected a novel database of 758 confidential, autobiographical narratives for personal moral events from 100 well-characterized healthy adults. Negatively valenced moral memories were significantly more remote than positively valenced memories, both as measured by the valence of the cue word that evoked the memory as well as by the content of the memory itself. The effect was independent of chronological age, ethnicity, gender or personality, arguing for a general emotional bias in how we construct our moral autobiography.

Goal-directed memory: The role of cognitive control in older adults' emotional memory.

The present study revealed that older adults recruit cognitive control processes to strengthen positive and diminish negative information in memory. In Experiment 1, older adults engaged in more elaborative processing when retrieving positive memories than they did when retrieving negative memories. In Experiment 2, older adults who did well on tasks involving cognitive control were more likely than those doing poorly to favor positive pictures in memory. In Experiment 3, older adults who were distracted during memory encoding no longer favored positive over negative pictures in their later recall, revealing that older adults use cognitive resources to implement emotional goals during encoding. In contrast, younger adults showed no signs of using cognitive control to make their memories more positive, indicating that, for them, emotion regulation goals are not chronically activated.

Specifying what makes a personal memory unique enhances emotion regulation.

During recollection of past experiences, the way autobiographical information is processed affects the intensity of the emotion aroused. Two main hypotheses were proposed in this respect: One focuses on the type of information activated during retrieval; the second is centered on the mode of processing at work. This article defends the notion that both perspectives need to be integrated to predict emotional arousal during autobiographical recollection. The authors explored the consequences on emotional feeling intensity by manipulating the type of information processed, together with the cognitive mode activated (specific vs. general level of processing). Results support previous findings that voluntarily specifying memories reduces emotional intensity. However, this was observed only when the details that make the event unique were processed.

The memory enhancement effect of emotion is absent in conceptual implicit memory.

Memory for emotional stimuli is superior to memory for neutral stimuli. This study investigated whether this memory advantage is present in implicit memory. Memory was tested with a test of explicit memory (associate cued recall) and a test of conceptual implicit memory (free association) identical in all respects apart from the retrieval instructions. After studying emotional and neutral paired associates, participants saw the first member of the pair, the cue; in the test of explicit memory participants were instructed to recall the associate; in the test of implicit memory participants were instructed to generate the first word coming to mind associated to the word. Depth of study processing dissociated performance in the tests, confirming that the free-association test was not contaminated by an intentional retrieval strategy. Emotional pairs were better recalled than neutral pairs in the test of explicit memory but not in the equivalent test of implicit memory. The absence of an emotion effect in implicit memory implies that emotional material does not have a privileged global mnemonic status; intentional retrieval is necessary for observing the emotion-related memory advantage.

Memory, emotion, and REM sleep.

Explored the manner in which REM sleep deprivation might affect various aspects of memory processing. A series of tests, including S. Sternberg's (see record 1966-10810-001) test of scanning of immediate memory, past personal and nonpersonal memory, and past emotional memories, was administered to 8 college students after baseline, control-awakening, and REM-deprivation nights. Results show that only past, emotionally important memories may have been affected by REM deprivation; access to the emotion connected with the memories was decreased. This finding is discussed in relation to a possible function of REM sleep and to the effects of REM deprivation on depression.

Mood and memory.

Describes experiments in which happy or sad moods were induced in Ss by hypnotic suggestion to investigate the influence of emotions on memory and thinking. Results show that (a) Ss exhibited mood-state-dependent memory in recall of word lists, personal experiences recorded in a daily diary, and childhood experiences; (b) Ss recalled a greater percentage of those experiences that were affectively congruent with the mood they were in during recall; (c) emotion powerfully influenced such cognitive processes as free associations, imaginative fantasies, social perceptions, and snap judgments about others' personalities; (d) when the feeling-tone of a narrative agreed with the reader's emotion, the salience and memorability of events in that narrative were increased. An associative network theory is proposed to account for these results. In this theory, an emotion serves as a memory unit that can enter into associations with coincident events. Activation of this emotion unit aids retrieval of events associated with it; it also primes emotional themata for use in free association, fantasies, and perceptual categorization.

A Prospective Study of Autobiographical Memory and Posttraumatic Stress Disorder Following Cancer.

In this study, the authors investigated the relationship between autobiographical memory and the onset and maintenance of distressing memories following cancer. In Study 1, participants recently diagnosed with head, neck, or lung cancer were assessed for acute stress disorder (ASD). Participants with ASD reported fewer specific memories than did participants without ASD. In Study 2, the same participants were assessed 6 months later for autobiographical memory and cancer-related posttraumatic stress disorder (PTSD). Deficits in the retrieval of specific memories in Study 1 were not predictive of subsequent PTSD. Increased hopelessness during the 6 months was associated with a decline in the retrieval of positive memories and an increase in the retrieval of negative memories. These findings accord with propositions that retrieval of distressing memories is guided by current self-image and attitude toward one's future.

Working memory capacity and the self-regulation of emotional expression and experience.

This research examined the relationship between individual differences in working memory capacity and the self-regulation of emotional expression and emotional experience. Four studies revealed that people higher in working memory capacity suppressed expressions of negative emotion (Study 1) and positive emotion (Study 2) better than did people lower in working memory capacity. Furthermore, compared to people lower in working memory capacity, people higher in capacity more capably appraised emotional stimuli in an unemotional manner and thereby experienced (Studies 3 and 4) and expressed (Study 4) less emotion in response to those stimuli. These findings indicate that cognitive ability contributes to the control of emotional responding. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reconstructing memory for emotions.

This research assessed the stability of peoples' memory for their past emotions over time and the role of changing appraisals in accounting for biases in emotion recall. Following Ross Perot's abrupt withdrawal from the presidential race in July 1992, supporters (N?=?227) rated their initial emotional reactions and described their interpretations of the event. After the elections in November, supporters (N?=?147) again recalled their initial emotional reactions and described their current appraisals of Perot. In contrast to some current models, memories for past emotions were not indelible, and a general tendency to overestimate the intensity of past emotions was not observed. Rather, systematic distortions in emotion recall were found in the direction of consistency with current appraisals. These findings support the conclusion that memories for emotional responses are partially reconstructed or inferred on the basis of current appraisals of events.

Stress, memory, and emotion: developmental considerations from the study of child maltreatment

Emotion and memory are examined within a developmental framework. The point of departure for this discussion is the study of maltreated children whose traumatic experiences have been linked to difficulties in emotional development. It is suggested that cognitive processes such as memory and attention serve to link experience with emotion and emotion with psychopathology. Thus, an information processing approach is used to explain the development of maltreated children's adaptive and maladaptive coping responses. It is argued that maltreated children's association of affective stimuli with traumatic experiences and memories selectively alters the meaning of emotions for these children. More generally, the role of experience and learning as a component of emotional development is emphasized.     

Psychobiology of active and inactive memory.

Presents a brief history and review of the short-term and long-term memory distinction and concludes that this distinction is no longer adequate for either human or animal memory data. Simple memories for events are apparently formed quickly and are permanent. In such cases, an initial physiologically unstable period is not required. Thus, most forgetting is the result of a retrieval failure rather than a storage failure. A distinction between active memory (AM) and inactive memory (IM) is made. AM is a subset of IM and contains either newly formed memories or established retrieved memories or both. Implications for psychobiology of the AM and IM distinction are discussed. It is suggested, for example, that while in AM, memories are particularly open to disruption either by amnesic agents or through other forms of interference. The forgetting process for new and established memories is time dependent (but independent of memory age) and is based on interference. It is desirable to maintain the distinction between memory storage and memory retrieval even while recognizing that associative storage aids in retrieval. The search for the biological basis of rapidly forming memories, perhaps based on the restructuring of protein fragments, remains important, but the physiological brain processes underlying memory interference and retrieval require greater emphasis.

Autobiographical memory phenomenology and content mediate attachment style and psychological distress.

In 2 studies, the present research tested the phenomenology and content of autobiographical memory as distinct mediators between attachment avoidance and anxiety and depressive symptoms. In Study 1, participants (N = 454) completed measures of attachment and depressive symptoms in 1 session and retrieved and rated 2 self-defining memories of romantic relationships in a separate session. In Study 2, participants (N = 534) were primed with attachment security, attachment insecurity, or a control prime and then retrieved and rated a self-defining relationship memory. Memory phenomenology, specifically memory coherence and emotional intensity, mediated the association between attachment avoidance and depressive symptoms, whereas the negative affective content of the memory mediated the association between attachment anxiety and depressive symptoms. Priming attachment security led to retrieval of a more coherent relationship memory, whereas insecurity led to the retrieval of a more incoherent relationship memory. Discussion focuses on the construction and recollection of memories as underlying mechanisms of adult attachment and psychological distress, the importance of memory coherence, and the implications for counseling research and practice.

Interactive effects of personality and mood on emotion-congruent memory and judgment.

Prior research on emotion congruency has tended to focus on either the effects of mood states or of personality traits on cognition. The aim of the present research was to explore when and how personality traits and mood states interact to influence emotion-congruent memory and judgment. In Study 1, participants filled out measures of personality and natural mood and then completed a series of memory and judgment tasks. The same procedure was used in Study 2, except a positive or negative mood state was induced prior to completion of the cognitive tasks. Extraversion and positive affectivity were related to retrieval of positive memories and the tendency to make positive judgments. Neuroticism and negative affectivity were related to retrieval of negative memories and the tendency to make negative judgments. In addition, several significant personality by mood interaction effects on memory and judgment were obtained in Study 2, which suggests that personality and mood effects on cognition are not independent of one another. Discussion focuses on integrating mood-congruency theories with personality theories and specifying the conditions under which mood by trait interaction effects emerge.
