Autobiographical Memory Specificity Research Articles

Age effects in autobiographical memory depend on the measure.

Studies examining age effects in autobiographical memory have produced inconsistent results. This study examined whether a set of typical autobiographical memory measures produced equivalent results in a single participant sample. Five memory tests (everyday memory, autobiographical memory from the past year, autobiographical memory from age 11–17, word-cued autobiographical memory, and word-list recall) were administered in a single sample of young and older adults. There was significant variance in the tests’ sensitivity to age: word-cued autobiographical memory produced the largest deficit in older adults, similar in magnitude to word-list recall. In contrast, older adults performed comparatively well on the other measures. The pattern of findings was broadly consistent with the results of previous investigations, suggesting that (1) the results of the different AM tasks are reliable, and (2) variable age effects in the autobiographical memory literature are at least partly due to the use of different tasks, which cannot be considered interchangeable measures of autobiographical memory ability. The results are also consistent with recent work dissociating measures of specificity and detail in autobiographical memory, and suggest that specificity is particularly sensitive to ageing. In contrast, detail is less sensitive to ageing, but is influenced by retention interval and event type. The extent to which retention interval and event type interact with age remains unclear; further research using specially designed autobiographical memory tasks could resolve this issue.

Maternal Emotional Reminiscing, Child Autobiographical Memory, and Their Associations with Pre-Schoolers’ Socioemotional Functioning

ABSTRACT This study aimed to explore the possible indirect pathway between maternal reminiscing style and child socioemotional functioning (prosocial behaviors and emotional adjustment difficulties) through children’s autobiographical memory (elaboration and specificity). A secondary exploratory aim was to examine whether cultural context moderated these indirect effects. Participants included 94 mother-child dyads drawn from middle- and high-income families in China and Australia. The dyads completed measures of child memory specificity, maternal report of child socioemotional functioning, and a shared emotional reminiscing task that assessed child memory elaboration and maternal sensitive guidance. Path analysis results indicated an indirect effect of maternal supportive reminiscing via child memory elaboration (but not memory specificity) on children’s prosocial behaviors, regardless of the cultural group. However, there was no evidence to suggest an indirect pathway between maternal supportive reminiscing and child adjustment difficulties (or prosocial behaviors) through child memory specificity in either cultural context. These findings provide preliminary support to the recent conceptualization of an indirect pathway between maternal sensitive guidance during emotional reminiscing and children’s prosocial behaviors through child memory elaboration. However, it is important to note that the cross-sectional design limits the causal inferences that can be drawn from the findings. The implications for memory specificity in child socioemotional functioning were less clear and indicated a need for further research in this area.

Autobiographical memory impairments as a transdiagnostic feature of mental illness: A meta-analytic review of investigations into autobiographical memory specificity and overgenerality among people with psychiatric diagnoses.

Decades of research has examined the difficulty that people with psychiatric diagnoses have in recalling specific autobiographical memories of events that lasted less than a day. Instead, they seem to retrieve general events that have occurred many times or which occurred over longer periods of time, termed overgeneral memory. We present the first transdiagnostic meta-analysis of memory specificity/overgenerality and the first meta-regression of proposed causal mechanisms. A keyword search of Embase, PsycARTICLES, and PsycINFO databases yielded 74 studies that compared people with and without psychiatric diagnoses on the retrieval of specific (k = 85) or general memories (k = 56). The majority of studies included participants with Major Depressive Disorder (∼49%), Schizophrenia (∼19%), and Posttraumatic Stress Disorder (∼17%) with few studies involving other groups of participants, for example, Anxiety Disorders (∼5%). Multilevel meta-analysis confirmed that people with psychiatric diagnoses typically recall fewer specific, g = -0.864, 95% CI [-1.030, -0.698], and more general, g = 712, 95% CI [0.524, 0.900], memories than diagnoses-free people. The size of these effects did not differ between diagnostic groups. There were no consistent moderators of effect size heterogeneity; effect sizes were not explained by methodological factors such as cue valence or demographic variables such as participants' age or between-group differences in process variables (e.g., rumination). Deficits in autobiographical memory retrieval may be a transdiagnostic factor, but further research in underrepresented diagnostic groups, and with novel experimental manipulations of encoding and retrieval processes, is warranted before full transdiagnosticity and the processes underlying reduced specificity/overgenerality can be established.

Lifetime Trauma History and Cognitive Functioning in Major Depression and Their Role for Cognitive-Behavioral Therapy Outcome.

While cognitive-behavioral therapy (CBT) is the gold-standard psychological treatment for major depression (MD), non-response and lacking stability of treatment gains are persistent issues. Potential factors influencing treatment outcome might be lifetime trauma history and possibly associated primarily prefrontal-cortex- and hippocampus-dependent cognitive alterations. We investigated MD and healthy control participants with (MD+T+, n = 37; MD-T+, n = 39) and without lifetime trauma history (MD+T-, n = 26; MD-T-, n = 45) regarding working memory, interference susceptibility, conflict adaptation, and autobiographical memory specificity. Further, MD+T+ (n = 21) and MD+T- groups (n = 16) were re-examined after 25 CBT sessions, with MD-T- individuals (n = 34) invited in parallel in order to explore the stability of cognitive alterations and the predictive value of lifetime trauma history, cognitive functioning, and their interaction for treatment outcome. On a cross-sectional level, MD+T+ showed the highest conflict adaptation, but MD+T- the lowest autobiographical memory specificity, while no group differences emerged for working memory and interference susceptibility. Clinical improvement did not differ between groups and cognitive functioning remained stable over CBT. Further, only a singular predictive association of forward digit span, but no other facets of baseline cognitive functioning, lifetime trauma history, or their interaction with treatment outcome emerged. These results indicate differential roles of lifetime trauma history and psychopathology for cognitive functioning in MD, and add to the emerging literature on considering cognitive, next to clinical remission as a relevant treatment outcome.

Specificity and wealth of autobiographical memories in restrictive and mixed anorexic patients.

The reduced specificity of positive and negative autobiographical memories observed in anorexic (AN) patients may reflect a global disturbance in their emotional information processing. However, their emotional difficulties may differ according to the subtype of AN, implying possible differences in the manifestation of autobiographical memory impairments. The aims of the study were (1) to confirm the autobiographical memory deficits in AN patients in terms of specificity and wealth of memories, and (2) to compare autobiographical deficits according to the AN subtype: restrictive type (AR) or binge/purging type (AB). Ninety-five non-clinical (NC) individuals and 95 AN patients including 69 AR and 22 AB patients were administered the Williams’ and Scott’s Autobiographical Memory Test. The results confirmed a lack of specificity regardless of emotional valence in the overall AN patient group without any distinction of subtype, which was linked to the number of hospitalizations. When the AN subtype was considered, AR patients demonstrated reduced specificity for negative memories only, suggesting differences in emotional functioning or in the mechanisms underlying reduced specificity between AR and AB patients. Furthermore, the overall AN group demonstrated lower variability and complexity in their memory content than the NC group. However, this difference in the complexity of recalled memories was only found in response to negative cues. When AN subtypes were considered, AR patients showed fewer complex memories than NC individuals. Beyond a reduced specificity, AN patients also depict a poverty in the range of event recall and a difficulty in developing narrative content. The clinical implications of such autobiographical memory deficits need to be further investigated.

ODor-evoked Autobiographical Memory in Alzheimer's disease?

Because memory decline is the hallmark of Alzheimer's disease (AD), an important endeavor for both clinicians and researchers is to improve memory performances in AD. This can be pursued by olfactory stimulation of memory in patients with AD and by studying the effects of olfactory stimulation on autobiographical memory (i.e., memory for personal information). The effects of olfactory stimulation on autobiographical memory in patients with mild AD have been reported by recent research. We thus provide the first comprehensive overview of research on odor-evoked autobiographical memory in AD. We also establish the basis for solid theoretical analysis concerning the memory improvement reported by research on odor-evoked autobiographical memory in AD. We examined literature on odor-evoked autobiographical memories in AD and propose the "OdAMA" (Odor-evoked Autobiographical Memory in Alzheimer's disease) model. According to OdAMA model, odor exposure activates involuntary access to specific autobiographical memories, which promotes enhanced experience subjective of retrieval in patients with AD and improves their ability to construct not only recent and remote events but also future ones. The OdAMA model could serve as a guide for researchers and clinicians interested in odor-evoked autobiographical memory in AD.

Individual Differences in Autobiographical Memory: The Autobiographical Recollection Test Predicts Ratings of Specific Memories Across Cueing Conditions

The Autobiographical Recollection Test (ART; Berntsen et al., 2019) measures individual differences in autobiographical memory. We here examined whether the ART correlates with characteristics of people’s specific autobiographical memories. Participants ( N s ≥ 475) completed the ART and rated recollective qualities of autobiographical memories cued by words (Study 1), by positive and negative emotional valence (Study 2), and by future and past temporal direction (Study 3). Scores on the ART consistently correlated with recollective qualities of specific memories and future thoughts, both immediately and after a 1-week delay. The magnitude of these correlations was at the same level as the correlations between individual memory items, underscoring the ability of the ART, as a trait measure to predict ratings of individual memories. The findings support the construct validity of the ART and demonstrate that people’s evaluation of their autobiographical memory, in general, is reliably related to how they remember specific events.

Neurophysiological correlates of disorder-related autobiographical memory in anorexia nervosa.

Anorexia nervosa (AN) is characterized by an overgeneralization of food/body-related autobiographical memories (AM). This is regarded as an emotion regulation strategy with adverse long-term effects implicated in disorder maintenance and treatment resistance. Therefore, we aimed to examine neural correlates of food/body-related AM-recall in AN. Twenty-nine female patients with AN and 30 medication-free age-sex-matched normal-weight healthy controls (HC) underwent functional magnetic resonance imaging while recalling AMs in response to food/body-related and neutral cue words. To control for general knowledge retrieval, participants engaged in a semantic generation and riser detection task. In comparison to HC, patients with AN generated fewer and less specific AMs in response to food/body-related words, but not for neutral cue words. Group comparisons revealed reduced activation in regions associated with self-referential processing and memory retrieval (precuneus and angular gyrus) during the retrieval of specific food/body-related AM in patients with AN. Brain connectivity in regions associated with memory functioning and executive control was reduced in patients with AN during the retrieval of specific food/body-related AM. Finally, resting-state functional connectivity analysis revealed no differences between groups, arguing against a general underlying disconnection of brain networks implicated in memory and emotional processing in AN. These results indicate impaired neural processing of food/body-related AM in AN, with a reduced involvement of regions involved in self-referential processing. Our findings are discussed as possible neuronal correlates of emotional avoidance in AN and provide new insights of AN-pathophysiology underscoring the importance of targeting dysfunctional emotion regulation strategies during treatment.

Mindfulness-Based Cognitive Therapy for Late-Life Depression: a Randomised Controlled Trial.

Rumination and overgeneral autobiographical memory are dysfunctional cognitions commonly found in older adults with depression. The theoretical underpinnings of mindfulness-based cognitive therapy (MBCT) address the ruminative tendencies and the non-specific retrieval of autobiographical memories. This study aims to examine the efficacy and cognitive mechanisms of MBCT in older adults with active depressive symptoms. 57 older adults (mean age, 70 years) with normal cognition and mild to moderate depressive symptoms were randomly allocated to either the MBCT group or the active control group for 8 weeks. The MBCT group consisted of eight 2-hour weekly sessions and a 7-hour full-day retreat, with different themes for each class, guided mindfulness exercises, feedback and discussion, homework review, and psychoeducation. The active control group comprised a 1-hour physical exercise and a standardised health education of the specific theme with group discussion (eg fall prevention, chronic pain). Participants were assessed before and after the 8-week intervention for four outcome measures: the Hamilton Depression Rating Scale (HAMD), the Ruminative Response Scale (RRS), the Autobiographical Memory Test (AMT), and the Mindful Attention Awareness Scale (MAAS). There was a significant reduction in severity of depressive symptoms (HAMD score) in both the MBCT group (F(1, 27) = 35.9, p < 0.001, η2 = 0.57) and the active control group (F(1, 28) = 9.29, p < 0.01, η2 = 0.24), but only the MBCT group showed substantial improvements in autobiographical memory specificity (AMT score), rumination (RRS score), and mindfulness (MAAS score). Although both MBCT and active control programme decrease the severity of depressive symptoms in older adults, only MBCT improves AMS, rumination, and mindfulness. Our findings provide empirical support for the theoretical underpinnings of MBCT. Older adults with more severe depression and more severe dysfunctional cognition may benefit more from the specific therapeutic effects of MBCT.

Specific Autobiographical Recall Mediates Impact of Cognition and Depression on Independence Function and Well-Being in Older Adults.

Autobiographical memory specificity has been associated with cognitive function, depression, and independence in older adults. This longitudinal study of 162 older adults moving to active supported living environments tracks changes in the role of the ability to recall specific autobiographical memory as a mediator between underlying cognitive function, or depression, and outcome perceived health or independence (e.g., Instrumental Activities of Daily Living, IADLs), across 18 months, as compared with controls not moving home. Clear improvements across time in autobiographical specificity were seen for residents but not controls, supporting the role of a socially active environment, and confirmed by correlation with number of activities reported in diaries, although the impact of diary activities on the effect of time on autobiographical specificity was not found. The role of autobiographical specificity in mediating general cognition and outcome functional limitations was clear for social limitations at 12 and 18 months, but its role in mediating effects of executive function and perceived health persisted throughout. The role of specificity in mediating between depression and perceived health, IADLs, and Functional Limitations persisted throughout. Analysis examining autobiographical specificity and depression as joint mediators between cognition and independence showed a forward effect such that higher specificity scores reduced the negative mediation effect of depression on independence. Finally, data showed the reduction of many of these mediations over time, supporting the role of autobiographical memory in times of change in a person's social situation. Data support potential autobiographical memory intervention development.

Clinical and Cognitive Functioning Changes After Partial Hospitalization in Patients With Anorexia Nervosa.

Introduction: Anorexia nervosa is usually associated with emotional and cognitive difficulties. Little knowledge is available about the changes in cognitive functioning in patients undergoing treatments. The aim of the present study was to longitudinally assess the impact of partial hospitalization on clinical and cognitive functioning in anorexia nervosa.Materials and Methods: 56 women with anorexia nervosa according to DSM-5 criteria and 58 healthy women were enrolled in the study. At baseline, all participants underwent clinical, diagnostic and neuropsychological assessment (T0). Patients were also assessed at the end of the treatment program (T1; n = 56).Results: BMI improved significantly throughout treatment. At baseline, patients showed significantly poorer executive abilities and less specific autobiographical memory. After the day-hospital program, decision-making abilities improved significantly. Response to treatment was predicted by BMI at admission and duration of illness, but neuropsychological performance did not contribute to the prediction model.Discussion: Cognitive difficulties, mostly regarding executive functions, resulted differently affected by clinical improvement. In particular, while cognitive monitoring and cognitive inhibition appear to be mostly stable trait-like characteristics, decision-making is both more state-dependent and sensitive to clinical status. None of the cognitive variables added information about the response to day hospital treatment; patients with short duration of illness and a rapidly decreasing BMI would benefit more from intensive interventions than less “acute” patients. These observations, if confirmed by future studies, have important clinical implications in order to understand the impact of malnutrition on cognitive functioning and to provide individualized effective treatment for patients with anorexia nervosa.

Autobiographical memory in Korsakoff syndrome: A review

Autobiographical memory (AM) (i.e., memory for personal information) is a unique form of memory that goes beyond recalling information such as what, where and when of an event, to include what that event means and why it is important to our life story. This paper therefore reviews the available literature on AM in Korsakoff syndrome (KS). It summarizes the characteristics of AM disorders in KS patients. These disorders are mainly characterized by the difficulties that patients with KS have in retrieving and reliving specific AMs and in retrieving recent and remote memories. Another core characteristic of AM disorders in KS is confabulations. This paper hypothesizes that patients with KS may produce autobiographical confabulations to support their objectives and beliefs or even to answer a social demand or simply to share personal experiences with others. Although the current evidence demonstrates disorders of AM in KS, there is a need for more research about the characteristics of these disorders. This review thus proposes several perspectives for theoretical and clinical research.

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.

The longitudinal association between individual differences in recall of positive specific autobiographical memories and daily cortisol

The present study examines the longitudinal association between cortisol (dys)regulation – mean cortisol awakening response (CAR) and area under the curve with respect to ground (AUCg) for total daily cortisol – and autobiographical memory. 135 participants (mean age at baseline = 16.1; Females = 78.5 %) provided cortisol samples (T1). Seven months later participants retrieved autobiographical memories cued by positive and negative words (T2). Four years subsequently, participants provided cortisol samples again (T3). The retrieval of more specific memories cued by positive words, but not negative words, was associated with higher AUCg four years later, independent of sex, recent life stressors and self-reported negative self-related cognitions. There were no associations between CAR and autobiographical memory. Neither AUC nor CAR at T1 predicted subsequent autobiographical memory abilities. People who retrieve more positive specific memories may be more likely to imagine and seek out positive experiences and this may be associated with higher cortisol levels.

Developmental and Intervention-Related Change in Autobiographical Memory Specificity in Maltreated Children: Indirect Effects of Maternal Reminiscing.

This study examined the development of autobiographical memory specificity (AMS) in a longitudinal randomized controlled trial of 242 maltreated and nonmaltreated children (aged 36-86months; 50.4% male; 39.7% Black, 25.9% White, 34.5% Latinx/other) and their mothers. Half of the maltreated families were randomized to receive an intervention to improve maternal reminiscing. The effects of maltreatment and the intervention on children's AMS via two indices of maternal reminiscing, sensitive guidance, and elaboration, were evaluated. Bidirectional associations between AMS and child maladjustment were also examined. Intervention-related improvement in maternal sensitive guidance 6-month postintervention (b*=.36) related to greater AMS among maltreated children 1year later (b*=.19). These findings underscore the role of maternal sensitive guidance in facilitating AMS.

Does self-focus orientation influence recall of autobiographical memories and subsequent mood in dysphoria?

ABSTRACT Past research suggests that depressed individuals are less likely than non-depressed individuals to engage in mood-incongruent recall in response to negative mood and do not experience associated mood reparative effects. The present study examined the effects of adopting a reflective versus ruminative self-focus orientation towards one's mood on the valence of autobiographical memories recalled following a negative mood induction and the extent of mood repair following memory recall among individuals with varying depressive symptomatology. Participants underwent a negative mood induction and either a ruminative (n = 69) or reflective (n = 49) self-focus manipulation, and then recalled five specific autobiographical memories. Depression symptoms were associated with recall of less positive memories and reduced mood repair. The valence of recalled memories was associated with the extent of mood improvement, and depressive symptoms did not moderate this association. Contrary to our hypothesis, a reflective self-focus was not associated with recall of more positive memories or greater mood improvement than a ruminative self-focus. The results suggest that more depressed individuals are less likely to spontaneously engage in mood-incongruent recall in a negative mood state; however, recall of positive memories is associated with similar mood reparative effects regardless of depressive symptomatology.

Early life adversity and the specificity of autobiographical memory amongst people with schizophrenia

BackgroundPeople with schizophrenia diagnoses are thought to have difficulty retrieving memories of specific autobiographical events because of attempts to avoid the negative affect associated with previous adversity. We provide the first investigation of the association between early adversity (e.g., childhood abuse) and autobiographical memory problems amongst people with and without schizophrenia. MethodParticipants with diagnoses of schizophrenia (n = 79) and participants without diagnoses (n = 41) completed the Maltreatment and Abuse Chronology of Exposure (MACE) interview schedule and a cued recall task. ResultsParticipants exposed to greater number of, and more severe, childhood adversity retrieved fewer specific autobiographical memories. However, participants with schizophrenia retrieved fewer specific memories than control participants without diagnoses irrespective of the presence, severity or number of adversities they experienced. ConclusionsAdversity contributes towards autobiographical memory difficulty but adversity does not explain why people with schizophrenia differ from diagnoses-free people in their autobiographical memory abilities.

Odor is more effective than a visual cue or a verbal cue for the recovery of autobiographical memories in AD

ABSTRACT Alzheimer’s disease (AD) is associated with an impairment of autobiographical memories, leading to the production of nonspecific memories. Recent research has demonstrated that odor can serve as a powerful cue for the retrieval of autobiographical memories in AD. Moreover, studies conducted in young adults have showed that odor-evoked autobiographical memories are evoked with more details compared with memories triggered by other sensory modalities. Building on the latter research, we compared specificity, subjective experience, emotional characteristics and retrieval time of autobiographical memories evoked by odor cue, visual cue and verbal cue. To this end, we invited participants with mild AD and control participants to retrieve autobiographical memories after the presentation of an odor, a visual representation of the odorant, or a verbal label of the odorant. Results showed more specificity, higher arousal and more positive memories after odor exposure compared to the visual cue and verbal cue in AD and control participants. In AD participants, autobiographical were retrieved faster after odor-exposure compared to memories evoked by a visual cue and a verbal cue, suggesting the automatic nature of odor-evoked autobiographical memories. Overall, these findings demonstrate that odor is more effective than visual or verbal cues for autobiographical retrieval in AD.

Impaired Autobiographical Memory Flexibility in Iranian Trauma Survivors With Posttraumatic Stress Disorder.

Reduced ability to retrieve specific autobiographical memories is a well-defined feature of posttraumatic stress disorder (PTSD), and science-driven interventions have emerged to improve memory specificity and thereby symptoms. However, research in depressed samples indicates that the ability to flexibly move between retrieval of specific and general memory types (i.e., memory flexibility) may more accurately conceptualize autobiographical memory deficits in emotional disturbance. In this study, we evaluated memory specificity and memory flexibility in Iranian trauma survivors (N = 63) with and without PTSD relative to community control participants. Trauma-exposed participants had experienced a serious road-traffic accident. Results indicated that individuals with PTSD experienced reduced memory specificity and memory flexibility relative to trauma-exposed participants and community control participants. A small sample size limits the strength of conclusions, although good statistical power was obtained. Findings suggest that reduced memory flexibility may be a transdiagnostic marker of emotional disturbance and support further development of memory flexibility interventions for PTSD.

Episodic Autobiographical Memory in Adults With Autism Spectrum Disorder: An Exploration With the Autobiographical Interview.

Introduction: The literature has provided contradictory results regarding the status of episodic memory in autism spectrum disorder (ASD). This might be explained by methodological differences across studies. In the present one, the well-recommended Autobiographical Interview was used in which important aspects of episodic memory were assessed, namely, the number and richness of phenomenological memory details, before and after a retrieval support.Method: Twenty-five well-documented adults with ASD without Intellectual Disability (nine women) and 25 control participants were included and asked to recall six specific autobiographical events. The number and richness of details were assessed globally and for five categories of details (perceptual/sensory, temporal, contextual, emotional, and cognitive), firstly before and then after a specific cueing phase consisting in a series of specific questions to elicit more precise memory details.Results: Cumulatively, from the spontaneous recall to the cueing phase, the number of internal details was lower in ASD individuals compared to controls, but this difference was relevant only after the specific cueing procedure and observed only for contextual details. In contrast, no relevant group difference was observed during spontaneous recall. The detail richness was not impaired in ASD throughout the Autobiographical Interview procedure.Conclusion: Our results speak against a clear impairment of episodicity of autobiographical memory in ASD individuals. They thus challenge previous ones showing both a reduced specificity and episodicity of autobiographical memory in this population and call for further studies to get a better understanding on the status of episodic autobiographical memory in ASD.
