Essentializing Happiness Mitigates the Changes in Subjective Well-Being Following Negative Life Events.

People hold different beliefs about the changeability of happiness. Some believe that happiness is biologically predetermined and thus unchangeable (essentialist beliefs), while others believe that it is malleable and can be changed (non-essentialist beliefs). Do these beliefs have a tangible impact on how individuals actually experience well-being? Here, we predict and empirically demonstrate that endorsing essentialist beliefs about happiness (EBH) can result in a self-fulfilling prophecy that buffers the changes in subjective well-being (SWB) following life events. Through a series of four studies utilizing diverse methodologies (total N = 7,364), we provide converging evidence that happiness essentialists, compared to non-essentialists, experience relatively stable levels of SWB following life events, particularly negative ones. We find that this pattern also emerges when people recall past events or anticipate hypothetical or impending future events. Together, happiness essentialism extends beyond mere belief and has real-world implications for how individuals experience fluctuations in SWB.

Involuntary Autobiographical Memory in Alzheimer's Disease: A Double-Edged Way of Remembering the Past?

Alzheimer's disease (AD) is characterized by severe memory alterations, affecting especially memories of personal past events. Until now, autobiographical memory impairments have been characterized using formal memory assessments, requiring patients to strategically and deliberately recall past events. However, contrary to this highly cognitively demanding mode of memory recall, autobiographical memories frequently come to mind unexpectedly based on automatic associative processes. The involuntary recall of personal memories is effortless and possibly represents a preserved way for AD patients to remember past events. This study aimed to investigate involuntary autobiographical memory in AD patients and compare the characteristics of these memories with those of healthy controls. Involuntary autobiographical memory was measured in 24 AD patients and 24 matched control participants using self-report measures. Participants were asked to report the frequency with which involuntary autobiographical memories were experienced in their daily life and to describe and self-assess one example of an involuntary memory. We showed that AD patients and control participants did not differ in terms of the frequency or subjective characteristics of their involuntary autobiographical memories in daily life, except for feelings of intrusiveness. Compared to control participants, AD patients reported their involuntary autobiographical memories as being more intrusive. In addition, more negative and vague involuntary autobiographical memories were associated with greater depressive symptoms. These findings open up a new avenue for research to better understand the extent to which involuntary autobiographical memory might be preserved in AD patients and why these memories may in turn become intrusive to patients.

REMINISCING AND RECOLLECTION OF LIFE IN ILIJA TROJANOW’S NOVEL THE WORLD IS BIG, AND SALVATION LURKS EVERYWHERE

IIija Trojanow, one of the Bulgarian writers of Contemporary German Literature, penned the story of the Luxow family's migration from Bulgaria to Germany in his first novel, "The World is Big, and Salvation Lurks Everywhere" (Die Welt ist groß und Rettung lauert überall, 1996). Employing self-reminiscences ingrained in his autobiographic memoir, the author reveals how the oppressive communist regime of the 70s affected society in the novel's story of the Luxow family. The novel is composed employing modern and post-modern narration techniques. The past is rendered in the story of Alex Luxow, the main character, who loses his family in a traffic accident in Germany and cannot recall past events before this accident. In addition, the main character's journeys in tandem with his godfather Bai Dan, who helps him in the healing process both physically and spiritually, indicate the search for an individual and cultural identity. This study discusses how the main character's memories of the overshadowed past are revived and what they point to while surpassing individual/cultural boundaries in the context of memory objects in autobiographical and collective reminiscences.

Dissecting cell-type-specific pathways in medial entorhinal cortical-hippocampal network for episodic memory.

Episodic memory, which refers to our ability to encode and recall past events, is essential to our daily lives. Previous research has established that both the entorhinal cortex (EC) and hippocampus (HPC) play a crucial role in the formation and retrieval of episodic memories. However, to understand neural circuit mechanisms behind these processes, it has become necessary to monitor and manipulate the neural activity in a cell-type-specific manner with high temporal precision during memory formation, consolidation, and retrieval in the EC-HPC networks. Recent studies using cell-type-specific labeling, monitoring, and manipulation have demonstrated that medial EC (MEC) contains multiple excitatory neurons that have differential molecular markers, physiological properties, and anatomical features. In this review, we will comprehensively examine the complementary roles of superficial layers of neurons (II and III) and the roles of deeper layers (V and VI) in episodic memory formation and recall based on these recent findings.

Neural correlates of mental time travel in individuals with high level of schizotypy

BackgroundMental time travel (MTT) is the ability to re-experience past events (autobiographic memory, AM) and pre-experience possible future events (episodic future thinking, EFT) through mental simulation. Empirical findings suggest that individuals with high level of schizotypy exhibit MTT impairment. However, the neural correlates of this impairment remain unclear. MethodThirty-eight individuals with high level of schizotypy and 35 low level of schizotypy were recruited to complete an MTT imaging paradigm. Participants were required to recall past events (AM condition), imagine possible future events (EFT condition) related to cue words, or generate exemplars related to category words (control condition) while undergoing functional Magnetic Resonance Imaging (fMRI). ResultsAM showed greater activation in precuneus, bilateral posterior cingulate cortex, thalamus, and middle frontal gyrus than EFT. Individuals with high level of schizotypy exhibited reduced activation in the left anterior cingulate cortex during AM (vs. Control) and in the medial frontal gyrus during EFT (vs. Control) compared to individuals with low level of schizotypy. Although psychophysiological interaction analyses did not show any significant group difference, individuals with high level of schizotypy exhibited functional connectivity between left anterior cingulate cortex (seed) and right thalamus, between medial frontal gyrus (seed) and left cerebellum during MTT, whereas individuals with low level of schizotypy did not exhibit these functional connectivities. ConclusionThese findings suggest that decreased brain activations may underlie MTT deficits in individuals with high level of schizotypy.

Mental time travel for self and others in individuals with a high level of schizotypy.

Mental time travel (MTT) is the ability to project oneself to the past or future through mental simulation. Moreover, MTT can involve self-related or other-related information. This study aimed to compare MTT in individuals with high levels of schizotypy and that in their counterparts with low levels of schizotypy. Participants with high (n=37) and low (n=37) levels of schizotypy completed an MTT task with four conditions [2 (Condition: self vs. other) × 2 (Time orientation: past vs. future)]. They were required to recall past events that had happened to themselves or to a non-intimate person, and to imagine possible future events that might happen to themselves or to a non-intimate person, related to cue words. Outcome measures included specificity, vividness, sense of experience, emotional valence, emotional intensity, proportion of first-person visual perspective in events, and difficulty in event generation. A 2 (Group: high vs. low levels of schizotypy) × 2 (Condition) × 2 (Time orientation) mixed analysis of variance was conducted on each index. Results showed that self-related MTT was more specific than other-related MTT inlow levels of schizotypy participants but not in high levels of schizotypy participants. Participants with a high levelof schizotypy reported fewer specific events, and reported events with lower vividness and positive emotion than did those with a low levelof schizotypy. Self-related MTT showed higher levels of phenomenological characteristics than did other-related MTT. In conclusion, individuals with a high level of schizotypy have altered MTT, and cannot benefit from the self-advantage effect on the specificity of MTT.

Reminiscence Content and Quality Among Community-Dwelling Older Adults in Japan

Objective: It is well known that reminiscence therapy improves mental health by encouraging the elderly to recall past life events; however, the content and how it can contribute to the intervention is still not fully understood. This study examined the relationship between reminiscence content and the quality of reminiscence and determined whether the latter was associated with depression, life satisfaction, and self-esteem.

Differences in memory for what, where, and when components of recently formed episodes.

An integral feature of human memory is the ability to recall past events. What distinguishes such episodic memory from semantic or associative memory is the joint encoding and retrieval of "what," "where," and "when" (WWW) for such events. Surprisingly, little work has addressed whether all three components of WWW are retrieved with equal fidelity when remembering episodes. To study this question, we created a novel task where human participants identified matched or mismatched still images sampled from recently viewed synthetic movies. The mismatch images only probe one of the three WWW components at a time, allowing us to separately test accuracies for each component of the episodes. Crucially, each WWW component in the movies is easily distinguishable in isolation, thereby making any differences in accuracy between components due to how they are joined in memory. We find that memory for "when" has the lowest accuracy, with it being the component most influenced by primacy and recency. Furthermore, the memory of "when" is most susceptible to interference due to changes in task load. These findings suggest that episodes are not stored and retrieved as a coherent whole but instead their components are either stored or retrieved differentially as part of an active reconstruction process. NEW & NOTEWORTHY When we store and subsequently retrieve episodes, does the brain encode them holistically or in separate parts that are later reconstructed? Using a task where participants study abstract episodes and on any given trial are probed on the what, where, and when components, we find mnemonic differences between them. Accuracy for "when" memory is the lowest, as it is most influenced by primacy, recency, and interference, suggesting that episodes are not treated holistically by the brain.

Lateral Entorhinal Cortex Suppresses Drift in Cortical Memory Representations.

Memory retrieval is thought to depend on the reinstatement of cortical memory representations guided by pattern completion processes in the hippocampus. The lateral entorhinal cortex (LEC) is one of the intermediary regions supporting hippocampal-cortical interactions and houses neurons that prospectively signal past events in a familiar environment. To investigate the functional relevance of the activity of the LEC for cortical reinstatement, we pharmacologically inhibited the LEC and examined its impact on the stability of ensemble firing patterns in one of the efferent targets of the LEC, the medial prefrontal cortex (mPFC). When male rats underwent multiple epochs of identical stimulus sequences in the same environment, the mPFC maintained a stable ensemble firing pattern across repetitions, particularly when the sequence included pairings of neutral and aversive stimuli. With LEC inhibition, the mPFC still formed an ensemble pattern that accurately captured stimuli and their associations within each epoch. However, LEC inhibition markedly disrupted its consistency across the epochs by decreasing the proportion of mPFC neurons that stably maintained firing selectivity for stimulus associations. Thus, the LEC stabilizes cortical representations of learned stimulus associations, thereby facilitating the recovery of the original memory trace without generating a new, redundant trace for familiar experiences. Failure of this process might underlie retrieval deficits in conditions associated with degeneration of the LEC, such as normal aging and Alzheimer's disease.SIGNIFICANCE STATEMENT To recall past events, the brain needs to reactivate the activity patterns that occurred during those events. However, such reinstatement of memory traces is not trivial because it goes against the natural tendency of the brain to restructure the activity patterns continuously. We found that dysfunction of a brain region called the LEC worsened the drift of the brain activity when rats repeatedly underwent the same events in the same room and made them behave as if they had never experienced these events before. Thus, the LEC stabilizes the brain activity to facilitate the recovery of the original memory trace. Failure of this process might underlie memory problems in elderly and Alzheimer's disease patients with the degenerated LEC.

Developmental changes in episodic memory across early- to mid-childhood: insights from a latent longitudinal approach

ABSTRACT Episodic memory is a cornerstone ability that allows one to recall past events and the spatiotemporal context in which they occur. In an effort to characterise the development of this critical ability, many different tasks have been used independently to assess age-related variations in episodic memory. However, performance on memory tasks is multiply determined, and the extent to which different tasks with varying features relate to each other and represent episodic memory as a latent cognitive construct across childhood is unclear. The present study sought to address this question by exploring the feasibility of using four different laboratory-based tasks to characterise changes in episodic memory ability during early- to mid-childhood in 200 typically developing children (4–8 years). Using longitudinal data and a structural equation modeling framework, results suggest that multiple tests of episodic memory can be utilised to indicate a comparable latent construct of episodic memory ability over this period of development, and that this ability improves consistently between 4 to 8 years. Overall, results highlight that episodic memory measured as a construct increases at a similar rate over early- to mid-childhood and demonstrate the benefits of using multiple laboratory tasks to characterise developmental changes in episodic memory.

Culture and visual perspective in mental time travel: the relations to psychological well-being

ABSTRACT Current understanding of visual perspectives (i.e., first person vs third person) in mental time travel and their relations to psychological well-being is largely based on research with Western populations. To examine whether culture moderates the processes, we asked European American (EA) and Asian or Asian American (AA) college students to recall and imagine personal experiences in ten social situations and to report their psychological well-being. AA participants imagined future events less from a third-person perspective than did EA participants, and there was no cultural difference in visual perspective in the recall of past events. Furthermore, EA participants who retrieved positive memories more from a third-person perspective exhibited worse well-being, whereas AA participants who imagined negative future events more from a third-person perspective exhibited better well-being. These findings advance our understanding of the role of culture in visual perspectives during mental time travel as they relate to psychological well-being.

Ripples for recall: The hippocampus constructing the context?

In this issue of Neuron, Norman etal. (2021) show that contrary to classical systems consolidation theories, hippocampal ripples orchestrate recall of both autobiographical and semantic memories. Similarity of ripple patterns furthermore suggests a semantization process as autobiographical memories age.

Detecting neural state transitions underlying event segmentation

Segmenting perceptual experience into meaningful events is a key cognitive process that helps us make sense of what is happening around us in the moment, as well as helping us recall past events. Nevertheless, little is known about the underlying neural mechanisms of the event segmentation process. Recent work has suggested that event segmentation can be linked to regional changes in neural activity patterns. Accurate methods for identifying such activity changes are important to allow further investigation of the neural basis of event segmentation and its link to the temporal processing hierarchy of the brain. In this study, we introduce a new set of elegant and simple methods to study these mechanisms. We introduce a method for identifying the boundaries between neural states in a brain area and a complementary one for identifying the number of neural states. Furthermore, we present the results of a comprehensive set of simulations and analyses of empirical fMRI data to provide guidelines for reliable estimation of neural states and show that our proposed methods outperform the current state-of-the-art in the literature. This methodological innovation will allow researchers to make headway in investigating the neural basis of event segmentation and information processing during naturalistic stimulation.

Reminiscence intervention for community-dwelling older adults without dementia: a literature review.

The aim of the present integrative literature review is to summarise empirical evidence supporting the positive health benefits of reminiscence intervention for older adults without dementia who reside in community and long-term care settings. Reminiscence intervention may be used to improve cognitive ability in older adults by prompting them to share life stories and recall past events. Using Garrard's matrix method, 15 studies were identified and included in this review, with a total of 815 participants. The health outcomes of reminiscence intervention for older adults residing in the community and long-term care settings were improvements in depressive symptoms; greater wellbeing, peace and life satisfaction; and improvements in quality of life, social engagement, anxiety and cognitive skills/memory. Non-pharmacological approaches such as reminiscence intervention may contribute to a rich base for reformulating cognitive interpretations, increasing cognitive abilities, and improving social skills among older adults.

An investigation of methods to improve recall for the patient-reported outcome measurement in COPD patients: a pilot randomised control trial and feasibility study protocol

BackgroundPatient-reported outcomes (PRO) are used to measure the effectiveness of interventions for management of chronic conditions such as chronic obstructive pulmonary disease. Many of these instruments require respondents to describe the change in their health status from baseline to a follow-up assessment and poor recall of previous health status often limits the usefulness and validity of these PRO measures. The use of technology has recently increased in PRO measurement. This study aims to mitigate the problems of poor recall by evaluating different strategies as a way to improve the validity of recall of health status among adults with COPD.MethodsA pilot randomised controlled trial of three strategies to improve patient recall will be tested in an acute care clinical environment. The first strategy is the use of tablet computer technology’s audio-visual facility, the second strategy is the provision of base line PRO responses prior to patients completing their follow-up questionnaires and third is standard practice of completing a questionnaire independently of previous responses. The feasibility of conducting this study in a busy clinical environment will be ascertained using the NIHR criteria for assessing feasibility.DiscussionThere is variability in a person’s ability to recall past events. With studies utilising patient-reported outcome measurement, it has become critically important to develop strategies and ways of supporting the patient to be more accurate recalling their health status. The adaptation of various technological features within mobile devices may provide an opportunity in clinical research studies to improve patient recall of their health status.Trial registrationANZCTR12618001605280.

Consumer Demographics and Self-Medication: A Cross-Sectional Study of Karachi City in Pakistan

The purpose of this study is to find the statistical relationship between self-medication and demographic characteristics. A cross-sectional study was conducted in the local settings of Karachi. A total of 210 individuals participated in the study. The data was collected through self-administered questionnaire. SPSS.20 was used for data analysis. This software help in data management from above mentioned sources, and statistical analysis of the data. Chi-square and Phi and Cramer’s V test was used to measure attitude of consumer towards self medications. The study shows that 82% of the surveyed people practice self-medication, mostly for minor illnesses. The common reasons for self-medication as stated by the respondents are prior experience, convenience, and recommendation. The majority of the respondent regarded self-medication as an acceptable practice and a short-term cure to the illness. Finally, there is no statistical relationship between self-medication and demographic characteristics of the population. The sample size that has been taken is small. Thus it is possible that the results do not give the exact image of the population. Moreover, responses of the participants could be inaccurate, as participants may not have been able to correctly recall past events.

Memory Loss: A Webliography

Memory loss is often the failure, or inability, to recall past events or knowledge. The loss of memory can be partial or total. The facets of memory loss encompass forgetfulness, amnesia, impaired memory, and total loss of memory. Forgetfulness is generally mild and is experienced by almost everyone at some point during life. Amnesia is complete loss of memories, such as name and personal history. Most memory loss occurs as part of the normal aging process, but memory loss may also occur because of mild cognitive impairment, medication or brain damage following disease or trauma. This article will introduce conditions contributing to memory loss and useful resources which may provide needed support.

Effectiveness of instrumental reminiscence intervention on improving coping in healthy older adults.

Reminiscence is a psychological intervention that uses the recall of past events, feelings, and thoughts to facilitate pleasure, quality of life, and adjustment to present life. The main goal of this study was to investigate the effect of a reminiscence intervention programme on coping strategies. One hundred fifty healthy older adults attended the reminiscence sessions. In order to evaluate the effects of the programme and find out if its effects lasted over time, we used an experimental design with pretest, posttest, and follow-up assessments, comparing a control group to the intervention group. Repeated-measures analysis of variance showed significant differences in problem-solving coping, positive reappraisal, social support seeking, and avoidance coping with the treatment group obtaining higher scores than the control group in all cases. The effects declined after 3months, but some differences were found in the treatment group obtaining higher scores in problem-solving coping and positive reappraisal and lower in overt emotional expression. The study suggests that reminiscence therapy contributes to mental health by enhancing coping strategies that can allow the elderly to cope successfully and overcome psychological distress.

The Effects of Manipulating Worry and Happiness on the Experience of Acute Pain and Worry about Pain

The empirical and clinical study of the relationship between emotions and pain has a long history. In the current study, participants rated pain intensity and worry about pain during noxious stimulation before and after they were asked to recall past events associated with worry, happiness, or pain. Participants in the worry condition evidenced increases in both pain intensity and worry about pain, and those in the happiness condition evidenced decreases in pain intensity and worry about pain, in response to the noxious stimulation. Asking participants to recall a physically painful episode had no significant effect on either pain intensity or pain-related worry. The effects of the emotion manipulation on pain were eliminated when the changes in worry about pain were controlled. The results are discussed in reference to the two-factor theory of pain and how the findings could inform clinical decisions.

On the origins of endogenous thoughts.

Endogenous thoughts are thoughts that we activate in a top-down manner or in the absence of the appropriate stimuli. We use endogenous thoughts to plan or recall past events. In this sense, endogenous thinking is one of the hallmarks of our cognitive lives. In this paper, I investigate how it is that we come to possess endogenous control over our thoughts. Starting from the close relation between language and thinking, I look into speech production-a process motorically controlled by the inferior frontal gyrus (IFG). Interestingly, IFG is also closely related to silent talking, as well as volition. The connection between IFG and volition is important given that endogenous thoughts are or at least greatly resemble voluntary actions. Against this background, I argue that IFG is key to understanding the origins of conscious endogenous thoughts. Furthermore, I look into goal-directed thinking and show that IFG plays a key role also in unconscious endogenous thinking.
