Relationship between personal recovery, autobiographical memory, and clinical recovery in people with mental illness in the acute phase

AimNarratives are important in psychiatric rehabilitation. People with a psychiatric diagnosis find it difficult to recall specific autobiographical memories of events that lasted less than a day. Although personal narratives play a central role in personal recovery, the factors influencing personal and clinical recovery, such as psychiatric symptoms and cognitive function, have not been fully explored. Therefore, this study examined the associations between personal recovery and autobiographical memory, age, psychiatric symptoms, and neurocognitive function. MethodThe Self-Identified Stage of Recovery, Parts A and B (SISR-A, SISR-B), Autobiographical Memory Test (AMT), Japanese version of the Brief Assessment Scale of Schizophrenia Cognitive Function, and Brief Psychiatric Symptom Rating Scale were administered to 40 individuals with psychiatric disorders who were undergoing psychiatric rehabilitation. ResultsA significant positive correlation was found between the total number of specific memories in the AMT and total SISR-B scores. A binary logistic regression analysis revealed that the total number of specific memories, especially high responsiveness to negative cue words, significantly predicted greater personal recovery. Age, psychiatric symptoms, and neurocognitive function did not significantly predict higher personal recovery. ConclusionIn psychiatric rehabilitation, negative episodes should be treated with caution; however, they may also facilitate personal recovery.

A Cross-Sectional Study of Cognitive Function, Illness Perceptions, and Immunosuppression Medication Adherence After Heart Transplantation.

There are few studies that examine relationships between cognitive function, illness perceptions, and medication adherence after heart transplantation, limiting the development of effective adherence-promoting interventions. The purpose of this study was to describe relationships between cognitive function, illness perceptions, and medication adherence among heart transplant recipients. A cross-sectional, observational design was used. Measures included the telephone-Montreal Cognitive Assessment (t-MoCA©), Patient Health Questionnaire-9, Brief Test of Adult Cognition by Telephone, Basel Assessment of Adherence to Immunosuppressive Medications Scale, and the Brief Illness Perceptions Questionnaire. Descriptive statistics, point-biserial correlations, Pearson's correlations, and logistic regression were used to describe relationships. Of the 35 participants (mean age: 61 years [SD: 10.3], 71.4% male, 71.4% white), 31.4% (n = 11) were classified as nonadherent to their immunosuppression medications. Higher immediate word recall, indicating better episodic memory (memory for autobiographical and recent events), and higher illness coherence scores were associated with not missing doses of medication. Higher t-MoCA© total scores, indicating normal cognitive function, and lower depression scores were associated with taking medications on time. More than 22% (n = 8) of participants scored less than 19 on the t-MoCA©, an indication of mild cognitive impairment. Cognitive impairment may be more common among heart transplant recipients than what is currently recognized, and specific domains of cognitive function were related to medication adherence after transplantation in this study. Future studies should include longitudinal evaluations of cognitive function, depression, and medication adherence. Consideration of these relationships is needed when designing adherence-promoting interventions for this population.

Scene construction and autobiographical memory retrieval in autism spectrum disorder.

Individuals with autism spectrum disorder (ASD) frequently exhibit difficulties in retrieving autobiographical memories (AMs) of specific events from their life. Such memory deficits are frequently attributed to underlying disruptions in self-referential or social cognition processes. This makes intuitive sense as these are hallmarks of ASD. However, an emerging literature suggests that parallel deficits also exist in ASD individuals' ability to reconstruct the rich spatial contexts in which events occur. This is a capacity known as scene construction, and in typically developing individuals is considered a core process in retrieving AMs. In this review, we discuss evidence of difficulties with scene construction in ASD, drawing upon experiments that involve AM retrieval, other forms of mental time travel, and spatial navigation. We also highlight aspects of extant data that cannot be accounted for using purely social explanations of memory deficits in ASD. We conclude by identifying key questions raised by our framework and suggest how they might be addressed in future research.

Self- and other-focused autobiographical memories of life story events across cultures

ABSTRACT Autobiographical memory and personal life stories are typically conceived as memories about the self. However, personal life stories often contain information about important events from other people’s lives. Sometimes those memories become an important part of our own life stories, illuminating the role that other people play in remembering our personal past. In this study, we examined the extent to which memories of important life story events are self-focused (e.g., I moved to Japan) or other-focused (e.g., My child graduated from college). Participants from Mexico, Greenland, China, Denmark and the United States recalled and dated seven autobiographical memories of important personal life story events. Participants also rated the memories for importance and emotional valence. The memories were coded as self- or other-focused. Participants recalled mainly self-focused memories. However, Danish and Chinese participants recalled about 20% other-focused memories. Danish participants recalled negative events about their parents, whereas Chinese participants recalled positive events about their children. Self-focused and other-focused memories differed in their emotional valence and lifespan distribution, but not in importance. The findings show that individuals remember other-focused memories and also incorporate them into their own personal life stories. Conceptual implications for autobiographical memory are discussed.

Is Deceitful Autobiographical Memory Really Forgotten?

Autobiographical memory for deceitful events is said to be forgotten over time to reduce guilt and stress. People who engage in deceitful behavior continue to do so because they are able to stretch their memories to match their moral outlook. In this study, the authors wanted to see if participants who engage in deceitful behavior will change their behavior if they are reminded of their previous misdeeds and compare it with reminding them of past moral behavior and any neutral event. We also studied how the experience, or phenomenology of remembering, differs between immoral and moral memories. In Experiment 1, we found evidence to suggest that reminding deceptive autobiographical memory does not reduce deceptive behavior. In Experiment 2, we found evidence to suggest phenomenological characteristics of Immoral and moral memories are not significantly different from each other but they are both significantly different from that of neutral memory. This contradicts established results in the field. It is interesting to note that only emotional valence is significantly different between immoral and moral memory.

Listeners’ effects on autobiographical memory for recent events

ABSTRACT The current study tested the effects of attentive versus distracted listening on both speakers and listeners in recall of an autobiographical memory. Participants included 128 pairs of friends who spoke with each other over a video call about recent negative experience that one of them had. Participants were randomly assigned to be speakers or listeners, and listeners were randomly assigned to an attentive and a distracted condition. Memory narratives were coded for factual and interpretive content. Participants returned approximately 4 weeks later, when both speaker and listener separately reported their memories of the prior conversation. Attentive listening was linked both to greater recall by the speaker at time 1 and greater listener recall at time 2, but not to speaker’s recall at time 2. Results show the effects of listener contributions to recall in the moment but raise questions as to whether they persist beyond the conversation in many scenarios.

Music cues impact the emotionality but not richness of episodic memory retrieval

ABSTRACT Previous studies have found that music evokes more vivid and emotional memories of autobiographical events than various other retrieval cues. However, it is possible such findings can be explained by pre-existing differences between disparate events that are retrieved in response to each cue type. To test whether music exhibits differential effects to other cues even when memory encoding is controlled, we compared music and environmental sounds as cues for memories of the same set of dynamic visual scenes. Following incidental encoding of 14 scenes (7 with music, 7 with sounds), the music and sounds were presented to participants (N = 56), who were asked to describe the scenes associated with these cues, and rate various memory properties. Music elicited fewer correct memories and more effortful retrieval than sound cues, and no difference was found in memory detail/vividness between cue types. However, music-evoked memories were rated as more positive and less arousing. These findings provide important critical insights that only partially support the common notion that music differs from other cue types in its effects on episodic memory retrieval.

Autobiographical event memory and aging: older adults get the gist.

We propose that older adults' ability to retrieve episodic autobiographical events, although often viewed through a lens of decline, reveals much about what is preserved and prioritized in cognitive aging. Central to our proposal is the idea that the so-called gist of an autobiographical event is not only spared with normal aging but also well adapted to serve memory-guided behavior in older age. To support our proposal, we review cognitive and brain evidence indicating an age-related shift toward gist memory. We then discuss why this shift likely arises from more than age-related decline and instead partly reflects a natural, arguably adaptive, outcome of experience, motivation, and mode-of-thinking factors. Our proposal reveals an upside of age-related memory changes and identifies important research questions.

"Be careful what you recall": Retrieval-induced forgetting of genuine real-life autobiographical memories.

Which episodes from our lives will be remembered and which will be forgotten, and why? This question has still not been answered satisfactorily by research into autobiographical memory. Previous work has shown that retrieval-induced forgetting (RIF) might be a factor responsible for forgetting parts of the autobiographical memory content. However, none of the previous studies assessed RIF in memories for recent, controlled, personal events. We report here the results of an experiment in which autobiographical memories of real-life events were induced in a controlled, but fully naturalistic, manner under the disguise of team-building exercises, while an adapted RIF paradigm was applied to these memories. Results clearly showed the influence of RIF on autobiographical memory retrieval. These findings demonstrate conclusively that RIF occurs in everyday life when remembering personal events.

Reminiscence groupwork and autobiographical memory as part of meaningful activities

The current paper describes a reminiscence group activity session held as part of meaningful activities engagement for older adults. Topics of reminiscence included both autobiographical memories and memories of broader historical events from the past. Participants included those with memory impairment and those without, and participants with healthy memory were helpful in prompting memories in participants with memory impairment. Semantic and episodic autobiographical memory were assessed at baseline and following the end of both group activities, using the Episodic Autobiographical Memory Interview (EAMI) and quality of life was assessed using the Quality of Life AD-scale (QOL-AD). The reminiscence intervention did not significantly affect autobiographical memory recall or quality of life. However, oral reminiscence was reported to have increased outside of the reminiscence sessions.

Zur Aufhebung von Scheinerinnerungen: Neue Befunde von Oeberst et al. (2021) und ihre aktuelle Übertragbarkeit in die forensische Praxis

A current finding by Oeberst et al. (2021) suggests a reversal of false memories of autobiographical events by means of source and false memory sensitization. The use of both techniques led to a significant reduction in the recollection quality of false memories in the sample examined. At the same time, the quality of memories of true experiences was barely diminished. Such results are seldom and significant, transferring them into forensic practice would be beneficial. However, if the meaningfulness and potential transferability of the results is examined more closely against the backdrop of forensic practice’s demands, it becomes apparent that using techniques in such a manner has not yet been sufficiently investigated and empirically verified. This applies to the psychological assessment of credibility as for the police questioning of witnesses. More details are discussed in the present article, whereby the study by Oeberst et al, its results, informative value and validity is successively and primarily referred to in relation to the psychological assessment of credibility.

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.

Autobiographical recall of a stressful negative event in veterans with PTSD

ABSTRACT Posttraumatic stress disorder (PTSD) is characterised by alterations in autobiographical memory for traumatic and non-traumatic events. Studies that focus on event construction – the ability to search for and identify a specific event – have documented overgeneral memory in PTSD. However, the quality of autobiographical memory also depends on the ability to elaborate on an event once constructed by providing additional details. In a prior study, individuals with PTSD generated as many episodic (event-specific) details as trauma-exposed controls when demands on event construction were minimized, albeit the PTSD group generated more non-episodic details. The current study sought to further characterize PTSD-related alterations in event elaboration by asking participants to describe a stressful negative event specified by the experimenter, thus minimizing event construction demands. Narratives were scored for episodic and non-episodic details and relations with measures of executive function and self-reported avoidance were examined. Compared to controls, the PTSD group generated narratives with equivalent episodic detail but greater non-episodic detail, including semantic information and repeated or extended events. Non-episodic detail generation was associated with greater avoidance but not executive functions. Elaborated non-trauma memories may be perceived as overgeneral in PTSD due to greater generation of non-episodic details, rather than diminished episodic detail.

Rich false memories of autobiographical events can be reversed

False memories of autobiographical events can create enormous problems in forensic settings (e.g., false accusations). While multiple studies succeeded in inducing false memories in interview settings, we present research trying to reverse this effect (and thereby reduce the potential damage) by means of two ecologically valid strategies. We first successfully implanted false memories for two plausible autobiographical events (suggested by the students' parents, alongside two true events). Over three repeated interviews, participants developed false memories (measured by state-of-the-art coding) of the suggested events under minimally suggestive conditions (27%) and even more so using massive suggestion (56%). We then used two techniques to reduce false memory endorsement, source sensitization (alerting interviewees to possible external sources of the memories, e.g., family narratives) and false memory sensitization (raising the possibility of false memories being inadvertently created in memory interviews, delivered by a new interviewer). This reversed the false memory build-up over the first three interviews, returning false memory rates in both suggestion conditions to the baseline levels of the first interview (i.e., to ∼15% and ∼25%, respectively). By comparison, true event memories were endorsed at a higher level overall and less affected by either the repeated interviews or the sensitization techniques. In a 1-y follow-up (after the original interviews and debriefing), false memory rates further dropped to 5%, and participants overwhelmingly rejected the false events. One strong practical implication is that false memories can be substantially reduced by easy-to-implement techniques without causing collateral damage to true memories.

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.

Autobiographical memory for repeated events: remembering our vacations

ABSTRACT We aimed to explore autobiographical memory for repeated events. For that aim, five instances of the same event category (i.e. last, first, random, distinct, and typical vacation) were collected from 57 (32 females) adults (Mage = 21.8; SDage = 2.0). Participants also provided the vacation scripts they have in mind. The last instances were expected to be highest in script consistency whereas the first instances would be the lowest due to duration between encoding and retrieval in addition to the frequency of potential script updates. We predicted that random instances selected freely by the participants would display high script-consistency due to ease of access. Finally, distinct instances would vary in their script consistency to the extent that they deviate from a script-consistent vacation experience. Overall, results were in line with the predictions. Findings are discussed in the context of the schema pointer plus tag model and the dynamic memory model.

Neuropsychological and neuropathological observations of a long-studied case of memory impairment

We report neuropsychological and neuropathological findings for a patient (A.B.), who developed memory impairment after a cardiac arrest at age 39. A.B. was a clinical psychologist who, although unable to return to work, was an active participant in our neuropsychological studies for 24 y. He exhibited a moderately severe and circumscribed impairment in the formation of long-term, declarative memory (anterograde amnesia), together with temporally graded retrograde amnesia covering ∼5 y prior to the cardiac arrest. More remote memory for both facts and autobiographical events was intact. His neuropathology was extensive and involved the medial temporal lobe, the diencephalon, cerebral cortex, basal ganglia, and cerebellum. In the hippocampal formation, there was substantial cell loss in the CA1 and CA3 fields, the hilus of the dentate gyrus (with sparing of granule cells), and the entorhinal cortex. There was also cell loss in the CA2 field, but some remnants remained. The amygdala demonstrated substantial neuronal loss, particularly in its deep nuclei. In the thalamus, there was damage and atrophy of the anterior nuclear complex, the mediodorsal nucleus, and the pulvinar. There was also loss of cells in the medial and lateral mammillary nuclei in the hypothalamus. We suggest that the neuropathology resulted from two separate factors: the initial cardiac arrest (and respiratory distress) and the recurrent seizures that followed, which led to additional damage characteristic of temporal lobe epilepsy.

Imagery Rescripting of Painful Memories in Social Anxiety Disorder: A Qualitative Analysis of Needs Fulfillment and Memory Updating

Imagery rescripting (IR) is an effective intervention for social anxiety disorder (SAD) that targets autobiographical memories of painful past events. IR is thought to promote needs fulfillment and memory updating by guiding patients to change unhelpful schema through addressing the needs of the younger self within the memory. Qualitative coding was used to examine the features of clinically relevant strategies enacted during IR to fulfill needs and update memories in 14 individuals with SAD. Participants typically enacted multiple strategies to address the needs of the younger self during rescripting, with compassionate and assertive strategies used more frequently than avoidance. Most strategies were practically feasible and enacted by the imagined self rather than imagined others, with the majority of patients achieving a strong degree of needs fulfillment, especially when strategies were consistent with identified needs. Participants’ reflections on how their memories have changed are provided from follow-up data collected 6 months post-intervention. Themes of self-reappraisal, self-compassion, and self-distancing are highlighted as potentially important for facilitating needs fulfilment and memory updating. Findings illuminate the clinical processes through which socially traumatic memories in SAD may be updated in IR by guiding patients to fulfill their needs and promote improved emotional health.

Default network contributions to episodic and semantic processing during divergent creative thinking: A representational similarity analysis

Cognitive and neuroimaging evidence suggests that episodic and semantic memory—memory for autobiographical events and conceptual knowledge, respectively—support different aspects of creative thinking, with a growing number of studies reporting activation of brain regions within the default network during performance on creative thinking tasks. The present research sought to dissociate neural contributions of these memory processes by inducing episodic or semantic retrieval orientations prior to performance on a divergent thinking task during fMRI. We conducted a representational similarity analysis (RSA) to identify multivoxel patterns of neural activity that were similar across induction (episodic and semantic) and idea generation. At the behavioral level, we found that semantic induction was associated with increased idea originality, assessed via computational estimates of semantic distance between concepts. RSA revealed that multivoxel patterns during semantic induction and subsequent idea generation were more similar (compared to episodic induction) within the left angular gyrus (AG), posterior cingulate cortex (PCC), and left anterior inferior parietal lobe (IPL). Conversely, activity patterns during episodic induction and subsequent generation were more similar within left parahippocampal gyrus and right anterior IPL. Together, the findings point to dissociable contributions of episodic and semantic memory processes to creative cognition and suggest that distinct regions within the default network support specific memory-related processes during divergent thinking.

Predicted and remembered emotion: tomorrow’s vividness trumps yesterday’s accuracy

ABSTRACTPeople rely on predicted and remembered emotion to guide important decisions. But how much can they trust their mental representations of emotion to be accurate, and how much do they trust them? In this investigation, participants (N = 957) reported their predicted, experienced, and remembered emotional response to the outcome of the 2016 U.S. presidential election. They also reported how accurate and vivid they perceived their predictions and memories to be, and the importance of the election. Participants remembered their emotional responses more accurately than they predicted them. But, strikingly, they perceived their predictions to be more accurate than their memories. This perception was explained by the greater importance and vividness of anticipated versus remembered experience. We also assessed whether individuals with Highly Superior Autobiographical Memory for personal and public events (N = 33) showed superior ability to predict or remember their emotional responses to events. They did not and, even for this group, predicting emotion was a more intense experience than remembering emotion. These findings reveal asymmetries in the phenomenological experience of predicting and remembering emotion. The vividness of predicted emotion serves as a powerful subjective signal of accuracy even when predictions turn out to be wrong.
