Influence of general and specific autobiographical recall on subsequent behavior: The case of cognitive performance

Two studies tested the impact of autobiographical recall of general versus specific academic success or failure on actual task performance. As expected, it was found that general memories of failure and specific memories of success resulted in worse performance than general memories of success and specific memories of failure. In Study 1, this performance pattern was obtained on a standard math test. In Study 2, it was replicated on a test of intellectual ability, and a mediation by fear of failure was documented. The present findings offer direct evidence that autobiographical memories of success and failure impact actual performance and also reveal the role of memory specificity in this influence.     

Motivational influence on the quality of memories: recall of general autobiographical memories related to desired attributes

This article concerns recall of general autobiographical memories in motivated self‐perception. General memories, comprising abstraction of repeated or similar behaviours, have more impact on how one defines oneself than do specific memories. In a study, participants were first induced to believe that either extraversion or introversion leads to success. In the recall task that followed, introversion‐success participants recalled more general memories related to introversion than did extraversion‐success participants. In contrast, extraversion‐success participants recalled more general extraverted memories than did introversion‐success participants. Thus, to preserve a positive self‐image as characterized by desirable attributes, recall may be directed towards generation of general memories related to the attributes.

The effect of burn injury on adolescents autobiographical memory

Autobiographical memory recall was investigated in two female adolescent groups; one group who had experienced a burn injury and a matched control group. The Burn group was not currently depressed or anxious, but scored significantly higher on the intrusion subscale of the impact of event scale compared to controls. Two autobiographical memory tasks, the autobiographical memory cueing task and the Children's Autobiographical Memory Inventory (CAMI), were used. For the cueing task, the Burn group was significantly slower to recall specific memories. This group also recalled significantly fewer specific memories and significantly more extended overgeneral memories. For the CAMI, the burns group produced significantly lower semantic and episodic recall. The Burn group also produced significant correlations between sub-scales of the impact of event scale and selected measures on the autobiographical memory tasks. Higher intrusion scores were associated with less detailed episodic recall. Higher avoidance scores were associated with longer latencies to recall memories to negative cue words and fewer specific memories to all cue words. These results are discussed from the perspective that the Burn group experienced intrusive thoughts which interfered with normal autobiographical functioning.     

Impaired autobiographical memory in complicated grief

This study investigated the relationship between autobiographical memory and goals in complicated grief (CG). Twenty-four individuals with CG and 21 bereaved individuals without CG completed an autobiographical memory task and a personal goals task. CG participants were more likely to recall memories related to their loss, particularly in response to negative cues. There was a positive relationship between the proportion of loss-related memories recalled and the proportion of grief-related goals held by individuals after controlling for symptom level. Individuals with CG also showed impaired retrieval of specific autobiographical memories in response to both positive and negative cues. These results suggest that CG is characterised by impaired and biased retrieval of specific autobiographical memories. These patterns are consistent with propositions stemming from the self-memory models of autobiographical memory.     

Effect of self-discrepancy on specificity of autobiographical memory retrieval

Research using a cue word paradigm has consistently shown that depression, in both adults and adolescents, is associated with difficulties in retrieving specific autobiographical memories. Inspired by previous work stating that depressed feelings are related to a perceived discrepancy between attributes of the actual and the ideal self, the present study aimed to investigate the hypothesis that cues bringing discrepancies between the actual and ideal selves to the foreground might promote or facilitate the recall of overgeneral (instead of specific) autobiographical memories. In two studies adolescents provided autobiographical memories in response to 10 high-discrepant and 10 low-discrepant words. As predicted, results in both studies showed an effect of cue word discrepancy on the specificity of autobiographical memories such that participants retrieved a smaller proportion of specific and a greater proportion of overgeneral memories in response to high-discrepant words as compared to low-discrepant words. The findings are discussed in terms of the self-memory system (SMS) as a conceptual framework of autobiographical memory (Conway & Pleydell-Pearce, 2000).     

The role of executive function in autobiographical memory retrieval: does the type of cue word matter?

ABSTRACT

Autobiographical memories are memories for personally experienced life events. Previous research has revealed individual differences in the ability to recall specific memories that happened at a particular time and place. Some studies suggest such differences can be attributed to the varying capacity of executive function. However, little is known regarding which specific executive function skills predict autobiographical memory specificity. Participants were asked to complete multiple measures of executive function as well as an autobiographical memory task in which they were asked to recall a specific personal memory connected to concrete and abstract cue words. We hypothesised that executive function will be positively related to autobiographical memory specificity and that this relation will be moderated by the cue word type. The results revealed that individuals with higher executive function skills, specifically, higher inhibitory control and cognitive flexibility, recalled significantly more specific memories than those with lower executive function skills; however, no significant interaction between executive function ability and cue word type was found.     

Priming autobiographical memories: How recalling the past may affect everyday forms of autobiographical remembering

This study investigated the idea that when one recalls past episodes, that the content of those memories will activate additional episodic memories with like content, and such memories will then have the potential of surfacing in subsequent acts of involuntary and voluntary recall. We tested the episodic content priming hypothesis in two experiments. In Experiment 1, priming group participants first recalled memories about specific activities or events and then they were subsequently engaged in a word-cue voluntary autobiographical memory task. The results showed that priming group participants produced more episodic memories involving the primed content on this task than control participants occupied in the same task. In Experiment 2, episodic content priming was further tested on a measure of involuntary autobiographical memory (i.e., the vigilance task). The results on this task also revealed support for the episodic content priming hypothesis, including after a delay of 24 h.     

Recollecting positive and negative autobiographical memories disrupts working memory

The present article reports two experiments examining the impact of recollecting emotionally valenced autobiographical memories on subsequent working memory (WM) task performance. Experiment 1 found that negatively valenced recollection significantly disrupted performance on a supra-span spatial WM task. Experiment 2 replicated and extended these findings to a verbal WM task (digit recall), and found that both negative and positive autobiographical recollections had a detrimental effect on verbal WM. In addition, we observed that these disruptive effects were more apparent on early trials, immediately following autobiographical recollection. Overall, these findings show that both positive and negative affect can disrupt WM when the mood-eliciting context is based on autobiographical memories. Furthermore, these results indicate that the emotional disruption of WM can take place across different modalities of WM (verbal and visuo-spatial).     

Rumination and overgeneral autobiographical memory

Two studies investigated the effects of rumination on the retrieval of autobiographical memories in high-depressed and low-depressed individuals. Experiment 1 administered either a rumination or distraction task prior to a cued autobiographical memory task. High-depressed participants recalled more overgeneral memories following rumination relative to distraction, whereas experimental inductions did not influence low-depressed participants. Experiment 2 administered either a positive or negative rumination task prior to a cued autobiographical memory task. Negatively valenced rumination led high-depressed participants to recall more overgeneral memories than positively valenced rumination; this effect was not observed in low-depressed participants. These findings accord with the proposal that rumination is a mediating mechanism in the retrieval of overgeneral memories, and extends this proposal by indicating that negatively valenced ruminative content is particularly instrumental in inducing overgeneral retrieval.     

Are the memories of older adults positively biased?

There is disagreement in the literature about whether a "positivity effect" in memory performance exists in older adults. To assess the generalizability of the effect, the authors examined memory for autobiographical, picture, and word information in a group of younger (17-29 years old) and older (60-84 years old) adults. For the autobiographical memory task, the authors asked participants to produce 4 positive, 4 negative, and 4 neutral recent autobiographical memories and to recall these a week later. For the picture and word tasks, participants studied photos or words of different valences (positive, negative, neutral) and later remembered them on a free-recall test. The authors found significant correlations in memory performance, across task material, for recall of both positive and neutral valence autobiographical events, pictures, and words. When the authors examined accurate memories, they failed to find consistent evidence, across the different types of material, of a positivity effect in either age group. However, the false memory findings offer more consistent support for a positivity effect in older adults. During recall of all 3 types of material, older participants recalled more false positive than false negative memories.     

Memory lane and morality: how childhood memories promote prosocial behavior

Although research has established that autobiographical memory affects one's self-concept, little is known about how it affects moral behavior. We focus on a specific type of autobiographical memory: childhood memories. Drawing on research on memory and moral psychology, we propose that childhood memories elicit moral purity, which we define as a psychological state of feeling morally clean and innocent. In turn, heightened moral purity leads to greater prosocial behavior. In Experiment 1, participants instructed to recall childhood memories were more likely to help the experimenter with a supplementary task than were participants in a control condition, and this effect was mediated by moral purity. In Experiment 2, the same manipulation increased the amount of money participants donated to a good cause, and both implicit and explicit measures of moral purity mediated the effect. Experiment 3 provides further support for the process linking childhood memories and prosocial behavior through moderation. In Experiment 4, we found that childhood memories led to punishment of others' ethically questionable actions. Finally, in Experiment 5, both positively valenced and negatively valenced childhood memories increased helping compared to a control condition.     

Posthypnotic amnesia for a first romantic relationship: Forgetting the entire relationship versus forgetting selected events

This experiment investigated the impact of suggestion focus on posthypnotic amnesia (PHA) for memories of a first romantic relationship. During hypnosis, high and low hypnotisable participants recalled specific memories from this period in response to 10 cue phrases (Elicitation). They then received a PHA suggestion that targeted either the entire period or specific memories from that period. Participants' explicit memory was indexed by cued recall after PHA was administered (memories recalled to “old” and “new” cues; Recall 1) and after it was cancelled (Recall 2). A social judgement task indexed dissociations between implicit and explicit memory. PHA had the greatest impact on highs', but not lows', memory performance (in terms of memories recalled to old cues, recall latency, and qualitative memory ratings) when the suggestion targeted the entire period rather than specific events. We discuss these findings in terms of the parameters of PHA's influence on memory, its value for exploring the nature and structure of autobiographical memory, and its utility as a laboratory analogue of functional amnesia.     

Autobiographical memory specificity, psychopathology, depressed mood and the use of the Autobiographical Memory Test: a meta-analysis

Reviewing the literature on autobiographical memory overgenerality, as measured by a cueing task like the Autobiographical Memory Test (AMT), gives a diffuse view of the moderating role of depression. This meta-analysis is an attempt to investigate the role of depression in the specificity of autobiographical memory, while accounting for the role of patient and task variables as possible moderators. Meta-analytic techniques are used to synthesize data from 14 studies on the recall of specific autobiographical memories in psychiatric and non-psychiatric samples. The results confirm the relationship between overgenerality and depression. The psychiatric patients are less specific than their non-clinical controls. It is not possible to establish that this result is solely due to a (co-morbid) diagnosis of depression. Self-reported depressed mood is also related to an impairment of autobiographical memory specificity. The way of presenting cues, audio taping responses and the maximum available amount of time to respond, are moderators of AMT performance.     

Closure of autobiographical memories moderates their directive effect on behaviour

Specific autobiographical memories have been theorised to serve a directive function, whereby the content of the memory directs behaviour outside awareness. The present research tested whether the extent to which a memory feels low in closure, or psychologically not in the past, moderates this directive effect. A total of 163 participants in an online experiment were asked to recollect a specific autobiographical memory of a time they had failed to donate to charity, or were not asked to recollect a memory. Those who recollected a memory were randomly assigned to think of the memory as high versus low in closure. Recollecting an autobiographical memory made to feel low in closure led to more memory-relevant behaviour than either recollecting a memory made to feel high in closure, or no memory at all. Moreover, the directive effect of a low-closure memory occurred whether participants were made aware of an upcoming behavioural opportunity or not. Discussion centres on possible processes linking low closure and behaviour, as well as implications for the self-memory system theory of autobiographical memory.     

Priming voluntary autobiographical memories: Implications for the organisation of autobiographical memory and voluntary recall processes

The goal of this study was to show that voluntary autobiographical memories could be primed by the prior activation of autobiographical memories. Three experiments demonstrated voluntary memory priming with three different approaches. In Experiment 1 primed participants were asked to recall memories from their elementary school years. In a subsequent memory task primed participants were asked to recall memories from any time period, and they produced significantly more memories from their elementary school years than unprimed participants. In Experiment 2 primed participants were asked to recall what they were doing when they had heard various news events occurring between 1998 and 2005. Subsequently these participants produced significantly more memories from this time period than unprimed participants. In Experiment 3 primed participants were asked to recall memories from their teenage years. Subsequently these participants were able to recall more memories from ages 13–15 than unprimed participants, where both had only 1 second to produce a memory. We argue that the results support the notion that episodic memories can activate one another and that some of them are organised according to lifetime periods. We further argue that the results have implications for the reminiscence bump and voluntary recall of the past.     

Autobiographical memory style in seasonal affective disorder and its relationship to future symptom remission

Autobiographical memory was examined in participants with seasonal affective disorder (SAD). In Experiment 1, participants with SAD performed an autobiographical memory task (AMT) in the winter, when depressed. The AMT required participants to generate autobiographical memories to positive and negative cue words. Symptom levels were reassessed in the summer, when participants were remitted. The number of overly general memories to positive cues generated when the SAD participants were depressed predicted symptom levels when remitted, over and above initial symptom levels, with greater winter overgenerality being associated with high levels of summer symptoms. However, this was dependent on the exact measure of depressive symptoms used. The degree of overgenerality of memories in SAD participants was further investigated in Experiment 2. Results revealed that SAD participants did not show elevated recall of overgeneral memories relative to controls. The results as a whole indicate that, even when levels of general memories are no greater in a given target group than in controls, the absolute level of general memories to positive cue words is still independently related to symptom outcome.     

A content analysis of involuntary autobiographical memories: examining the positivity effect in old age

Although research on autobiographical memory is growing steadily, very little is known about involuntary autobiographical memories that are spontaneously recalled in everyday life. In addition, very few studies have examined the actual content of autobiographical memories and how the content might change as a function of age. The present study carried out a content analysis of involuntary autobiographical memories recorded by young (N = 11) and old (N = 10) volunteers over a period of 1 week. A total of 224 memories were classified into 17 categories according to the type of content recalled (e.g., births, holidays, school). The results support the socioemotional theory of ageing (Carstensen, Isaacowitz & Charles, 1999) by showing that although young and old adults recalled a similar number of memories with a typically positive content (e.g., holidays, special occasions), older adults recalled very few memories with a typically negative content (e.g., accidents, stressful events). Moreover, even when such negative memories were recalled, they were rated by older adults as neutral or even positive. This so-called positivity effect in old age could not be entirely explained by participants' ratings of mood at the time of recall. Theoretical and practical implications of these findings for ageing and autobiographical memory research are discussed.     

Involuntary autobiographical memories in and outside the laboratory: How different are they from voluntary autobiographical memories?

In two studies, we compared the characteristics and retrieval times of involuntary and voluntary autobiographical memory under controlled laboratory conditions. A new laboratory task of involuntary autobiographical memories involved detecting vertical lines in a stream of stimuli with horizontal lines (an undemanding vigilance task) and recording any involuntary memories during the session. The majority of these memories were reported as being triggered by irrelevant cue phrases presented on the screen. Voluntary autobiographical memories were sampled via a standard word-cue method in Session 2. The results showed that involuntary memories were more specific and were retrieved significantly faster than voluntary memories. They were also more likely to be triggered by negative cues, whereas cue valence did not have any effect on the number of voluntary memories. Furthermore, laboratory involuntary memories did not differ from naturalistic involuntary memories recorded in a diary by the same participants (Study 2). Taken together, these results have important implications for current theories of autobiographical memory, and they open up interesting avenues for future research.     

Involuntary autobiographical memories in dysphoric mood: a laboratory study

The frequency and characteristics of involuntary autobiographical memories were compared in 25 stable dysphoric and 28 non-dysphoric participants, using a new laboratory-based task (Schlagman & Kvavilashvili, 2008). Participants detected infrequent target stimuli (vertical lines) in a simple vigilance task and recorded any involuntary autobiographical memories that came to mind, mostly in response to irrelevant words presented on the screen. Dysphoric participants reported involuntary memories as frequently and as quickly as non-dysphoric participants and their memories were not repetitive intrusive memories of negative or traumatic events. Additional content analysis showed that dysphoric participants did not recall more memories of objectively negative events (e.g., accidents, illnesses, deaths) than non-dysphoric participants. However, significant group differences emerged in terms of a mood congruency effect whereby dysphoric participants rated their memories as more negative than non-dysphoric participants. Moreover, the proportion of negatively rated involuntary memories was related to lower mood ratings at the end of the session in the dysphoric but not in the non-dysphoric group. Finally, groups did not differ on several memory characteristics such as vividness, specificity (high in both groups) and rates of rehearsal (low in both groups). Theoretical and practical implications of these findings for research on depression and autobiographical memory are discussed.     

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.
