Meta-memory (prediction) of specific autobiographical recall: An experimental approach using a modified autobiographical memory test.

Autobiographical memory specificity is known to contribute to better mental health, social problem-solving, and episodic future thinking. While numerous studies have addressed variables that affect autobiographical memory specificity, little is known regarding the meta-memory processes that underpin memory retrieval. In this study, we introduced two meta-memory constructs, ease of retrieval judgments and anticipation of negative emotion evoked, which potentially affect autobiographical memory specificity. Participants (N = 109) first rated the ease of retrieval and anticipated emotions for positive and negative words used in a subsequent autobiographical memory test. We used the Optional Instructions of the Autobiographical Memory Test, in which participants were instructed that "specific memories are better, but other memories are permissible," allowing them to adjust how much cognitive effort they spent on generative retrieval after a failure of direct retrieval. They also self-judged whether each retrieval was generative (using additional cues with cognitive effort) or direct (immediate recall without much cognitive effort). Results showed that for generative retrieval, ease of retrieval was associated with greater specific and general memories and fewer omissions. A more negative anticipated emotion was associated with fewer specific memories and greater omissions, but was not with general memories. These results suggest that low retrievability and anticipated negative emotion prevent individuals from devoting efforts to generative retrieval. The lack of association between anticipated negative emotion and general memory calls into question the functional avoidance hypothesis regarding autobiographical memory specificity. We discussed how participants judged these meta-memories and directions for future research.

Direct accessibility for overgeneral memory predicts a worse course of depression: re-analysis of the online computerised memory specificity training for major depression study.

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms.

Working it out: can an acute exercise bout alleviate memory bias, rumination and negative mood?

Although it is well known that exercise reduces depressive symptoms, the underlying psychological mechanisms remain unclear. This experimental study examined the acute effect of exercise on mood, and depressotypic memory bias and state rumination. Trait rumination was tested as a possible moderator. A sample of non-regular exercisers (N = 100) was randomized to exercise or rest. After a negative mood induction, the exercise condition cycled for 24 min at moderate intensity, while the rest condition rested. Negative and overgeneral memory bias, as well as positive and negative affect were assessed after exercise/rest. To capture the lingering of negative mood and state rumination, both were assessed multiple times throughout the study. The exercise (as compared to rest) condition reported more positive affect. However, no differences were found on overgeneral memory bias, as well as depression-specific mood or state rumination measured throughout the study. Interestingly, the exercise condition showed more negative memory bias at higher levels of rumination. Individual differences in trait rumination moderated the exercise-memory bias relation, such that exercise increased negative memory bias at higher levels of rumination. It is possible that long-term exercise protocols are necessary to change cognitive processes related to depression.

Reduced specificity and increased overgenerality of autobiographical memory persist as cognitive vulnerabilities in remitted major depression: A meta-analysis.

Difficulty in accessing specific memories, referred to as reduced memory specificity or overgeneral memory (OGM), has been established as a marker of clinical depression. However, it is not clear if this deficit persists following the remission of depressive episodes. The current study involved a systematic review and meta-analysis of empirical studies with the aim of establishing whether remitted depression was associated with retrieving fewer specific and more overgeneral autobiographical memories. Seventeen studies were identified as eligible. The results indicated that people with remitted depression recalled fewer specific memories (k = 15; g = -0.314, 95% CI [-0.543; -0.085], z = -2.69, p = .007) and more categoric memories (k = 9; g = 0.254, 95% CI [0.007; 0.501], z = 2.02, p = .043) compared to people who had never been depressed. Given these deficits have elsewhere been shown to be prognostic of future depressive symptoms, these findings suggest that reduced memory specificity/overgeneral memory persists following remission and may be a risk factor for future episodes of depression in those that are in remission. The findings are discussed in terms of how this knowledge might influence clinical understanding of relapse prevention and maintenance of remission in those with a history of depression.

Direct retrieval bias for general and specific memories for negatively valenced cues in major depression.

Major depressive disorder (MDD) is associated with reduced specificity in autobiographical memory. It has been argued that this tendency occurs through a failure of effortful generative retrieval, regardless of valence of cue word. However, we propose that in MDD general memories are likely to be recalled via direct retrieval, and direct retrieval is more likely for negatively valenced cues. To provide a preliminary test of this, a large sample with MDD (N = 298; M age = 47.2) completed the autobiographical memory test and indicated whether retrievals were generative or direct. Categoric and extended memories for negatively valenced cues were more often directly retrieved than generatively retrieved, and more often than direct retrieval for positively valenced cues. In contrast, categoric and extended memories for positively valenced cues were more often generatively retrieved relative to generative retrieval for negatively valenced cues. Relative to non-clinical samples, direct retrieval for negatively valenced cues was high. Retrieval method and valence may be moderating processes in the type of memories recalled. This preliminary work presents the possibility of an extension of theory on retrieval tendencies in MDD.

Overgeneral and specific autobiographical memory predict the course of depression: an updated meta-analysis.

Impairments in retrieving event-level, specific autobiographical memories, termed overgeneral memory (OGM), are recognised as a feature of clinical depression. A previous meta-analytic review assessing how OGM predicts the course of subsequent depressive symptoms showed small effects for correlations and regression analyses when baseline depressive symptoms were controlled for. We aimed to update this study and examine whether their findings replicate given the decade of research that has been published since. A systematic literature review using the same eligibility criteria as the previous meta-analysis led to a doubling of eligible studies (32 v. 15). The results provided more precise estimates of effect sizes, and largely support the finding that OGM predicts the course of depressive symptoms. The effects were generally small, but significantly larger among clinical samples, compared to studies with non-clinical samples. There was some evidence that higher age was associated with stronger effects, and longer follow-up was associated with weaker effects. The findings on other moderating variables that were analysed were mixed. Continued research into this modifiable cognitive process may help to provide an avenue to better understand and treat highly prevalent and impactful depressive disorders.

Intergenerational transmission of autobiographical memory specificity: Indirect effects through maternal reminiscing.

Mother-child reminiscing, particularly maternal sensitive guidance, fosters the development of autobiographical memory specificity (AMS) in both typically developing and maltreated children, yet little is known regarding the processes underlying individual differences in maternal reminiscing that could also relate to child AMS. Emerging evidence has shown that maternal AMS is associated with maternal sensitive guidance in typically developing dyads. We extended this research to the context of maltreatment, a risk factor for impoverished maternal sensitive guidance and reduced AMS in children. In the current study, we evaluated the indirect effect of maternal AMS on child AMS through two dimensions of maternal reminiscing style-sensitive guidance and elaboration-while including parallel pathways between neglect and abuse/emotional maltreatment and child AMS through maternal reminiscing. Participants were 123 neglecting, 30 abuse/emotional maltreating, and 78 demographically matched nonmaltreating mothers and their 3- to 6-year-old children. Results indicated that maternal AMS was indirectly associated with child AMS through maternal sensitive guidance while controlling for associations among neglect, maternal reminiscing, and child AMS, providing evidence for intergenerational transmission of AMS in at-risk dyads. These results advance the understanding of mechanisms underlying both maternal sensitive guidance and child AMS in a low-socioeconomic-status and racially diverse sample.

Differential associations between impaired autobiographical memory recall and future thinking in people with and without schizophrenia.

OBJECTIVES: The ability to think about future events serves a range of important functions. People with schizophrenia show impairments in future thinking. However, whether these impairments are specific to positive or negative events and to what extent they are associated with impairments in verbal fluency and autobiographical memory remains poorly understood. METHODS: People with schizophrenia (n = 93) and people without psychiatric diagnoses (n = 111) were asked to generate future events and retrieve past autobiographical events and they also completed a test of verbal fluency. Participants also completed questionnaire measures of the positive and negative dimensions of schizophrenia and depression symptoms. RESULTS: People with schizophrenia generated significantly fewer positive and negative future events than controls. In a linear regression, the interaction between diagnosis and autobiographical memory retrieval explained a significant amount of variance in the number of future events that participants generated even when accounting for symptoms and verbal fluency. Past and future thinking abilities were correlated in controls but not in people with schizophrenia. CONCLUSIONS: People with schizophrenia may not rely on autobiographical content to imagine the future and may rely instead on semantic processes. Interventions that improve past and future thinking amongst people with schizophrenia are warranted. PRACTITIONER POINTS: Compared to control participants, people with schizophrenia have marked difficulty generating possible, positive and negative, future events. Unlike controls, for people with schizophrenia there is no relation between their ability to remember past events and their ability to think about the future. People with schizophrenia may have difficulty using their memories for their past to imagine and simulate possible future events.

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.

Valence-related impairments in the retrieval of specific autobiographical memories amongst patients with schizophrenia.

OBJECTIVES: People with schizophrenia have difficulty recalling specific autobiographical events from their past. However, the nature of this difficulty (e.g., whether these problems are only for memories that are negative or positive) and the mechanisms associated with it remain poorly understood. METHODS: The present investigation asked patients with schizophrenia (n = 91) and healthy controls (n = 109) to recall memories related to several positive and negative cue words. Participants also completed self-report measures of rumination and depressive symptoms and a measure of verbal fluency to assess executive functioning. Participants' memories were coded for specificity (whether or not they referred to a specific event lasting <24 hr) and valence (positive vs. negative). RESULTS: Patients recalled fewer specific memories than controls and they showed particular difficulty recalling specific negative memories cued by negative words. For healthy controls, impoverished verbal fluency was associated with recall of fewer specific memories and particularly recall of fewer positive specific memories. These variables were unrelated to specificity amongst patients. Rumination was not associated with specificity in either group. CONCLUSIONS: These findings are discussed with reference to other mechanisms that might contribute towards reduced specificity in schizophrenia, such as the tendency to avoid negative affect, and the implications of this for interventions for schizophrenia and memory specificity problems. PRACTITIONER POINTS: The experience of schizophrenia is associated with problems recalling specific events from one's past. In particular, patients have difficulty recalling specific negative memories from their past. These memory problems are independent of executive functioning difficulties, ruminative tendencies, and also depression symptoms. Interventions for memory problems in schizophrenia must target the difficulty people have in recalling specific negative events.

A test of the CaR-FA-X mechanisms and depression in adolescents.

People who have depression have difficulty recalling specific autobiographical information (Sumner, (2011) The mechanisms underlying overgeneral autobiographical memory: An evaluative review of evidence for the Ca R-FA-X model. Clinical Psychology Review, 3231(1), 34-48). This is called overgeneral autobiographical memory (OGM) and is associated with the development and persistence of depression. Williams, Barnhofer, Crane, Hermans, Raes, Watkins, & Dalgleish (2007 Autobiographical memory specificity and emotional disorder. Psychological Bulletin, 133(1), 122-148) proposed that OGM is maintained by three mechanisms: capture and rumination (CaR), functional avoidance (FA), and impaired executive control (X), and integrated these into the CaR-FA-X model. The aim of this study was to assess OGM and test the CaR-FA-X model in adolescents with low mood. We recruited 29 young people aged 12-17 with elevated symptoms of depression and 29 with minimal symptoms of depression, matched for gender and age. After controlling for IQ, adolescents with elevated depression retrieved fewer specific memories, ruminated more, and had poorer working memory and verbal fluency than adolescents with minimal depression. The groups did not differ on measures of inhibition or functional avoidance. The CaR-FA-X model was therefore partially supported. These results confirm that there is a relationship between low mood and OGM in young people and that OGM may arise as consequence of impaired working memory and verbal fluency and cognitive interference due to rumination.

Social support from friends predicts changes in memory specificity following a stressful life event.

Exposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N = 143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.

Retrieval process of overgeneral memory and the capture and executive control hypothesis: using Autobiographical Memory Test with thought sampling.

The retrieval process for underlying overgeneral autobiographical memory remains unclear. In this study, we identified what leads to self-referential and categoric thoughts and examined the influence error-monitoring ability has on the reporting of categoric memories. We also examined whether cue self-relevance and/or executive control task performance are related to the number of specific memories reported. Using thought sampling, 94 college students completed the Autobiographical Memory Test, as well as a verbal fluency task and a depression scale. The results indicated that depressive symptoms and negative highly self-relevant cues were associated with self-referential/categoric thoughts during memory retrieval. Further, preceding self-referential/categoric thoughts and low error-monitoring ability predicted immediate after-reporting of categoric memories. Simultaneously, highly self-relevant cues and executive control task performance predicted the reporting of many specific memories. Subdividing the retrieval process and examining the process involved in depression are essential.

Distinctions between autobiographical memory specificity and detail: Trajectories across cue presentations.

Autobiographical memory is central to identity and self-awareness, but individuals with depression and Post-Traumatic Stress Disorder tend to have overgeneral memories. Recent research has suggested that the ability to retrieve specific memories and individual differences in the amount of detail in specific memories are independent (Kyung, Yanes-Lukin, & Roberts, 2016). We re-analyzed data from Kyung et al. to test whether these constructs are distinct in terms of their trajectories over cue presentations. Results indicated a U-shaped trajectory for specificity, but a inverted-U trajectory for detail, suggesting a dissociation in which periods of decreasing probability of retrieving specific memories correspond to increasing amounts of detail. Further, trajectories had similar forms when memories included emotional content, but differed for recollections that did not include emotional content. Finally, at the individual level, slopes for specificity and detail across trials were uncorrelated. These findings provide further support for the independence of these constructs.

A test of the functional avoidance hypothesis in the development of overgeneral autobiographical memory.

Overgeneral memory (OGM) refers to the failure to recall memories of specific personally experienced events, which occurs in various psychiatric disorders. One pathway through which OGM is theorized to develop is the avoidance of thinking of negative experiences, whereby cumulative avoidance may maladaptively generalize to autobiographical memory (AM) more broadly. We tested this, predicting that negative experiences would interact with avoidance to predict AM specificity. In Study 1 (N = 281), negative life events (over six months) and daily hassles (over one month) were not related to AM specificity, nor was avoidance, and no interaction was found. In Study 2 (N = 318), we revised our measurements and used an increased timeframe of 12 months for both negative life events and daily hassles. The results showed no interaction effect for negative life events, but they did show an interaction for daily hassles, whereby increased hassles and higher avoidance of thinking about them were associated with reduced AM specificity, independent of general cognitive avoidance and depressive symptoms. No evidence was found that cognitive avoidance or AM specificity moderated the effect of negative experiences on depressive symptoms. Our findings suggest that life events over 6-12 months are not associated with AM specificity, but chronic daily hassles over 12 months predict reduced AM specificity when individuals avoid thinking about them. The findings provide evidence for the functional-avoidance hypothesis of OGM development and future directions for longitudinal studies.

Do Overgeneral Memories Make us feel better? An experimental examination.

A critical assumption of the CaR-FA-X model, that overgeneral memory is partly attributable to the "functional avoidance" of specific details about one's past experiences, has not been experimentally tested. Further, while it is assumed that the reinforcing properties of said avoidance leads to the emergence of an overgeneral recall style over time, this question has not been addressed developmentally. To explore these issues, two studies were conducted. In Study 1, 41 children and adolescents (Mage = 12 years) were randomly assigned to recall overgeneral or specific negative memories on the Autobiographical Memory Test; participants later listened to their memories and provided pre- and post-tests of their emotional states at four time points: before and after memory generation and before and after memory exposure. In Study 2, 52 college-aged participants (Mage = 19 years) completed the same protocol. Results indicated that children and adolescents in the overgeneral condition reported higher levels of positive affect relative to those in the specific condition, while recall condition did not impact adults' emotional states. These findings were not explained by differences in emotion regulation strategies or psychopathological symptoms. Implications for developmental models of autobiographical memory and emotion regulation are discussed.

Investigating whether maternal memory specificity is indirectly associated with child memory specificity through maternal reminiscing.

Maternal reminiscing and remembering has a profound influence on the development of children's autobiographical remembering skills. The current study investigated the relationships between maternal memory specificity, maternal reminiscing and child memory specificity. Participants consisted of 40 mother-child dyads. Children's age ranged between 3.5 and 6 years. Mothers and children participated in individual assessments of autobiographical memory specificity. Dyads participated in a joint reminiscing task about three past emotional (happy, sad, stressful) events. A positive moderate association was found between maternal autobiographical memory specificity and child autobiographical memory specificity. Maternal autobiographical memory specificity was significantly correlated with mothers' focus on the task, involvement and reciprocity, resolution of negative feelings, and structuring of narratives in the mother-child reminiscing task. Moderate positive associations were found between maternal focus and structuring and child memory specificity. There was no evidence to suggest maternal elaborative reminiscing style was significantly positively correlated with mother or child memory specificity. Finally, there was support for an indirect pathway between maternal memory specificity and child memory specificity through quality of support and guidance provided by the mother in maternal reminiscing. Theoretical and clinical implications are considered.

The Impact of Upward versus Downward Movement Patterns on Memory Characteristics of Depressed Individuals.

BACKGROUND/AIMS: Basic research on embodiment has demonstrated that manipulating the motoric system has broad effects on cognitive and emotional processes. The aim of the present study was to investigate the effects of an embodiment manipulation on the affective memory bias and specificity of autobiographic memories of depressed individuals. METHODS: Forty currently depressed patients practiced either an upward-opening Qi Gong movement, which runs counter to the habitual slumped and downward depressive movement style, or a downward-closing Qi Gong movement. They were required to retrieve specific personal memories to positive or negative cue words during movement. Moreover, an incidental recall of the cue words was conducted. RESULTS: Patients in the upward-opening movement condition in contrast to the downward-closing movement condition showed a more positively biased recall of affective words and recalled more specific autobiographical memories. CONCLUSIONS: Results indicate that the motoric system and key maintaining cognitive factors in depressive disorders are closely interrelated.

Overgeneral autobiographical memory and depression in older adults: a systematic review.

OBJECTIVES: Overgeneral autobiographical memory (OGM) is a well-researched phenomenon in working age adults with depression. However, the relevance and importance of OGM in older adult depression is not well established. The aim of this review was to synthesise existing literature on OGM and depressive symptoms in older adults under the framework of the Capture and Rumination, Functional Avoidance and Impaired Executive Control (CaR-FA-X) model. METHOD: Literature searches were conducted using PsychINFO, PubMed and Web of Knowledge. Eighteen articles were reviewed. RESULTS: OGM is elevated in healthy older adults compared to adults of working age, and further elevated in older adults with depression. Evidence supports the role of impaired executive function as a mechanism for OGM in older adults with depression, but no studies measured other components of the CaR-FA-X model (i.e. functional avoidance and rumination). CONCLUSION: OGM is prevalent in older adults and more so for those with depression; however, there is no clear understanding of the underpinning mechanisms. It is recommended that future research looks at the role of functional avoidance and rumination, and at the use of memory specificity interventions being developed in the working age adult literature.

Is remembering less specifically part of an avoidant coping style? Associations between memory specificity, avoidant coping, and stress.

Individuals higher on avoidant coping may remember fewer specific autobiographical memories and more nonspecific memories on the Autobiographical Memory Test (AMT) in order to protect themselves from the painful emotions accompanying some specific memories. Habitually remembering this way (overgeneral memory) may be a risk factor for depression. In Studies 1 and 2 (nondepressed samples), avoidant coping was associated with more specific memories and fewer overgeneral memories, at odds with the functional avoidance view. In Study 3 (depressed sample), there were no significant relationships between AMT indices and avoidant coping. Results are discussed in light of ironic process theory.
