Bayesian evaluation of diverging theories of episodic and affective memory distortions in dysphoria

People suffering from dysphoria retrieve autobiographical memories distorted in content and affect, which may contribute to the aetiology and maintenance of depression. However, key memory difficulties in dysphoria remain elusive because theories disagree how memories of different valence are altered. Here, we assessed the psychophysiological expression of affect and retrieved episodic detail while participants with dysphoria (but without a diagnosed mental illness) and participants without dysphoria relived positive, negative, and neutral memories. We show that participants with dysphoria retrieve positive memories with diminished episodic detail and negative memories with enhanced detail, compared to participants without dysphoria. This is in line with negativity bias but not overgeneral memory bias theories. According to confirmatory analyses, participants with dysphoria also express diminished positive affect and enhanced negative affect when retrieving happy memories, but exploratory analyses suggest that this increase in negative affect may not be robust. Further confirmatory analyses showed that affective responses to memories are not related to episodic detail and already present during the experience of new emotional events. Our results indicate that affective memory distortions may not emerge from mnemonic processes but from general distortions in positive affect, which challenges assumptions of memory theories and therapeutics.

Measuring hearing aid satisfaction in everyday listening situations: Retrospective and in-situ assessments complement each other

Background: Recently, we developed a hearing-related lifestyle questionnaire (HEARLI-Q) which asks respondents to rate their hearing aid (HA) satisfaction in 23 everyday listening situations. It is unknown how HA satisfaction on the retrospective HEARLI-Q scale compares to HA satisfaction measured on the same scale implemented in Ecological Momentary Assessments (EMA). Purpose: To learn how retrospective (HEARLI-Q) and in-situ (EMA) assessments can complement each other. Research Design: An observational study. Study Sample: Twenty-one experienced HA users. Data Collection and Analysis: The participants first filled out the HEARLI-Q questionnaire, followed by a one-week EMA trial using their own hearing aids. HA satisfaction ratings were compared between the two questionnaires and the underlying drivers of discrepancies in HA satisfaction ratings were evaluated. Results: HA satisfaction scores were significantly higher in EMA for speech communication with one or several people. Hearing difficulty in these situations was rated higher in HEARLI-Q than in EMA, but occurrence of those difficult listening situations was also rated to be lower. When comparing only the situations that occur on daily or weekly basis, the two questionnaires had similar HA satisfaction ratings. Conclusions: Lower occurrence of difficult listening situations seems to be the key driver of discrepancies in HA satisfaction ratings between EMA and HEARLI-Q. The advantage of EMA is that it provides insight into an individual’s day-to-day life and is not prone to memory bias. HEARLI-Q, on the other hand, can capture situations which occur infrequently or are inconvenient to report in the moment. Administering HEARLI-Q and EMA in combination could give a more holistic view of HA satisfaction.

Assessing cognitive biases induced by acute formalin or hotplate treatment: an animal study using affective bias test

Pain, a universal and burdensome condition, influences numerous individuals worldwide. It encompasses sensory, emotional, and cognitive facets, with recent research placing a heightened emphasis on comprehending pain’s impact on emotion and cognition. Cognitive bias, which encompasses attentional bias, interpretation bias, and memory bias, signifies the presence of cognitive distortions influenced by emotional factors. It has gained significant prominence in pain-related research. Human studies have shown that individuals experiencing pain exhibit cognitive bias. Similarly, animal studies have demonstrated cognitive bias in pain-induced states across various species and disease models. In this study, we aimed to investigate the memory bias displayed by rats experiencing acute pain, using the affective bias test (ABT) as a tool and administering either hotplate or formalin to induce acute pain. Our data showed that rats demonstrated a significant preference for the control treatment-related substrate over the substrate associated with formalin treatment (p < 0.001), an indication of the prominent memory bias stimulated by acute formalin injections. However, when exposed to substrates related to hotplate treatment and control treatment, the acute pain induced by the hotplate treatment failed to generate a statistically significant choice bias in rats (p = 0.674). Our study demonstrates that the negative emotions associated with acute pain can be reflected by memory bias in ABT, at least for formalin-induced acute pain. This finding will augment our comprehension of the emotional and cognitive aspects of acute pain.

More organized white matter is associated with positivity bias in older adults.

On average, healthy older adults prefer positive over neutral or negative stimuli. This positivity bias is related to memory and attention processes and is linked to the function and structure of several interconnected brain areas. However, the relationship between the positivity bias and white matter integrity remains elusive. The present study examines how white matter organization relates to the degree of the positivity bias among older adults. We collected imaging and behavioral data from 25 individuals (12 females, 13 males, and a mean age of 77.32). Based on a functional memory task, we calculated a Pos-Neg score, reflecting the memory for positively valenced information over negative information, and a Pos-Neu score, reflecting the memory for positively valenced information over neutral information. Diffusion-weighted magnetic resonance imaging data were processed using Tract-Based Spatial Statistics. We performed two non-parametric permutation tests to correlate whole brain white matter integrity and the Pos-Neg and Pos-Neu scores while controlling for age, sex, and years of education. We observed a statistically significant positive association between the Pos-Neu score and white matter integrity in multiple brain connections, mostly frontal. The results did not remain significant when including verbal episodic memory as an additional covariate. Our study indicates that the positivity bias in memory in older adults is associated with more organized white matter in the connections of the frontal brain. While these frontal areas are critical for memory and executive processes and have been related to pathological aging, more extensive studies are needed to fully understand their role in the positivity bias and the potential for therapeutic interventions.

The effects of life experiences and polygenic risk for depression on the development of positive and negative cognitive biases across adolescence: The CogBIAS hypothesis.

The Cognitive Bias (CogBIAS) hypothesis proposes that cognitive biases develop as a function of environmental influences (which determine the valence of biases) and the genetic susceptibility to those influences (which determines the potency of biases). The current study employed a longitudinal, polygenic-by-environment approach to examine the CogBIAS hypothesis. To this end, measures of life experiences and polygenic scores for depression were used to assess the development of memory and interpretation biases in a three-wave sample of adolescents (12-16 years) (N = 337). Using mixed effects modeling, three patterns were revealed. First, positive life experiences (PLEs) were found to diminish negative and enhance positive forms of memory and social interpretation biases. Second, and against expectation, negative life experiences and depression polygenic scores were not associated with any cognitive outcomes, upon adjusting for psychopathology. Finally, and most importantly, the interaction between high polygenic risk and greater PLEs was associated with a stronger positive interpretation bias for social situations. These results provide the first line of polygenic evidence in support of the CogBIAS hypothesis, but also extend this hypothesis by highlighting positive genetic and nuanced environmental influences on the development of cognitive biases across adolescence.

Judgments during perceptual comparisons predict distinct forms of memory updating.

Comparing a visual memory with new visual stimuli can bias memory content, especially when the new stimuli are perceived as similar. Perceptual comparisons of this kind may play a mechanistic role in memory updating and can explain how memories can become erroneous in daily life. To test this possibility, we investigated whether comparisons can produce other types of memory distortion beyond memory bias that are commonly implicated in erroneous memories (e.g., memory misattribution). We hypothesized that the type of memory distortion induced during a comparison depends on the perceived overlap between the memory and incoming stimulus-when the input is perceived as similar, it biases memory content; when perceived as the same, it replaces memory content. Participants completed a delayed estimation task in which they compared their memories of color (Experiment 1) and shape stimuli (Experiment 2) to probe stimuli before reporting memory content. We found systematic errors in participants' memory reports following perceived similarity and sameness that were toward the probes and larger following perceived sameness. Simulations confirmed that these errors were not explained by noisy encoding processes that occurred before comparisons. Instead, computational modeling suggested that these errors were likely explained by the probabilistic replacement of the memory by the probe following perceived sameness and integration between the memory and the probe following perceived similarity. Together, these findings suggest that perceptual comparisons can prompt distinct forms of memory updating that have been described previously and may explain how memories become erroneous during their use in everyday behavior.

Impact of memory bias in the dietary estimation of older adults measured through a food frequency questionnaire and weighed food records: A cross-sectional study in older adults and primary caregivers.

Introduction: changes in cognitive performance and memory of older adults (OA) can interfere in their reporting their diet. Objective: to evaluate the impact of memory bias in dietary estimation between OA and their primary caregivers (PC) through the food frequency questionnaire (FFQ) for Mexican OA and weighed food records (WFR). Methods: the present analysis uses the estimated dietary information based on the response provided by 51 older adults (OA) and their primary caregivers (PC) from the validation study of the FFQ for Mexicans OA was conducted during lockdowns for COVID-19. The personnel who applied FFQ and WFR were trained with standardized instruments and procedures. The Wilcoxon test was used to compare the intake per day of the foods and food groups, the Spearman correlation coefficient was used to evaluate the grams of intake per day of the food groups, and kappa coefficient was used to compare the level of food items and food groups between OA and PC. Results: in 11 of 14 food groups, no significant differences were observed between the amounts of intake reported by OA and PC. In the groups of dairy products, fruits, vegetables, and legumes, moderate agreement was observed (κ = 0.63 to 0.79), and in the rest of the groups was strong to perfect (κ ≥ 0.80). Correlation of the amount of intake between OA and PC was high in all food groups (r ≥ 0.87). Conclusion: the high correlation and high agreement between the amounts and frequencies of the food groups consumed as reported by the older adults and primary caregivers indicate that the information from both respondents is reliable.

Social Memory, Public Memory, and Marginality: The Case of the “Death in Migration”

Memory is a source of ‘immunization’ for individuals (psycho-cognitive memory and biological immune system) and for communities (De Martino). We can consider culture as the memory of society. Particularly, the cultural memory of disasters plays a fundamental role. Ideally, it should help to reduce the vulnerability of societies to the risks of recurrence of natural/technological/social catastrophic events. However, memory is not an exact process, but a selective and reconstructive one (Bartlett). Furthermore, the memory of society is multiple and continuously exposed to the risk of distortions, interpretations, and manipulations. Social memory (Halbwachs) is the broader sphere of communicability that delimits the arena in which the different collective memories (of groups) compete for the relevance and plausibility of their own discourses. It will correspond, with good approximation, to the term “public memory”. In particular, the media and journalism play a very important function, as public memory is a memory of the public sphere (Habermas) and, somehow, the public sphere is itself memory (Jedlowski). This presentation aims to compare two social memories of a single catastrophic event in which a marginal social category was involved: migrants illegally crossing the Mediterranean Sea. The research focus concerns a watershed event of the recent migratory phenomenon: the Lampedusa shipwreck that took place on the 3<sup>rd</sup> October 2013. The goal is to show how collective and public memory contrast each other. We will discuss two cultural and communicative processes located along the oppositional materialization/dematerialization axis. In the article we will reinterpret the evidence collected in the research carried out in 2014 on the Lampedusa shipwreck that took place on 3 October 2013 in order to reflect on the dynamics between different types of memories in the framework of the memory of disasters. We assume that they can be deeply distortive as they promote interrelated memory bias.

AUTONOMIC ACTIVITY AND THE AGING BRAIN

Abstract Aging affects both autonomic activity and the brain regions that help modulate autonomic activity. In this symposium, we present new findings on how the relationships between autonomic activity and the brain change in aging. In addition, we demonstrate that modulating autonomic activity can affect the aging brain and emotional and cognitive functions controlled by the brain. Kathy Liu will present research from over 600 participants showing that, unlike younger adults who show the expected positive relationship between heart rate variability (HRV) and brain and behavioral indicators of emotion regulation, older adults showed a negative relationship between HRV and emotion regulation. Julian Thayer will present findings on how blood pressure and total peripheral resistance relate to brain structure. Richard Song will present functional MRI data revealing that the older brain shows less blood oxygen level dependent (BOLD) response to physiological fluctuations than younger brains. Jungwon Min will present findings that random assignment to daily biofeedback to either increase or decrease heart rate oscillations had a large effect on plasma amyloid-β. Mara Mather will present a new theoretical model positing that older brains attempt to compensate for hyperactive peripheral sympathetic activity, and that this ventromedial prefrontal compensatory activity leads to the biases in attention and memory known as the age-related positivity effect. Together, the empirical findings and theoretical perspectives presented in this symposium indicate that the autonomic system exerts important influences over the aging brain and that this provides a significant opportunity for intervening to improve brain health.

THE EMOTION PARADOX IN THE AGING BODY AND BRAIN

Abstract With age, parasympathetic activity decreases while sympathetic activity increases. Thus, the typical older adult has low heart rate variability (HRV) and high noradrenergic activity. Younger adults with this physiological profile tend to be chronically unhappy and stressed. Yet, with age, emotional experience tends to improve. Why doesn’t older adults’ emotional well-being suffer as their HRV decreases? To address this apparent paradox, I present the autonomic compensation model. In this model, failing organs and initial phases of Alzheimer’s pathology trigger noradrenergic hyperactivity in older adults. Older brains attempt to compensate by increasing autonomic regulatory processes in ventromedial prefrontal (vmPFC) cortex. Age-related declines in nerve conduction reduce the ability of these compensatory attempts to reduce hyperactive noradrenergic activity and increase peripheral HRV. However, despite their muted effects on peripheral autonomic activity, these autonomic compensation attempts bias brain processing in favor of stimuli that tend to increase parasympathetic activity and against stimuli that tend to increase sympathetic activity. The autonomic compensation model can account for the “age-related positivity effect” in which, compared with younger adults, older adults show attentional and memory biases favoring positive over negative stimuli. Consistent with the autonomic compensation model, the age-related positivity effect is associated with vmPFC activity and functional connectivity and is evident even in early attention processes resistant to goal-directed processing. The autonomic compensation model posits that the aging brain responds to sympathetic hyperactivity in ways that amplify on-going automatic emotion regulation processes and so help maintain emotional well-being.

Social feedback biases emerge during recall but not prediction and shift across the development of social anxiety.

Memory is a reconstructive process that can result in events being recalled as more positive or negative than they actually were. While positive recall biases may contribute to well-being, negative recall biases may promote internalizing symptoms, such as social anxiety. Adolescence is characterized by increased salience of peers and peak incidence of social anxiety. Symptoms often wax and wane before becoming more intractable during adulthood. Open questions remain regarding how and when biases for social feedback are expressed and how individual differences in biases may contribute to social anxiety across development. Two studies used a social feedback and cued response task to assess biases about being liked or disliked when retrieving memories vs. making predictions. Findings revealed a robust positivity bias about memories for social feedback, regardless of whether memories were true or false. Moreover, memory bias was associated with social anxiety in a developmentally sensitive way. Among adults (study 1), more severe symptoms of social anxiety were associated with a negativity bias. During the transition from adolescence to adulthood (study 2), age strengthened the positivity bias in those with less severe symptoms and strengthened the negativity bias in those with more severe symptoms. These patterns of bias were isolated to perceived memory retrieval and did not generalize to predictions about social feedback. These results provide initial support for a model by which schemas may infiltrate perceptions of memory for past, but not predictions of future, social events, shaping susceptibility for social anxiety, particularly during the transition into adulthood.

Emotional Bias among Individuals at Risk for Seasonal Affective Disorder-An EEG Study during Remission in Summer.

Emotional bias in attention and memory is well researched in depression. Patients with depression prioritize processing of negative information over positive input. While there is evidence that emotional bias exists in seasonal affective disorder (SAD) during winter, it is unclear whether such altered cognition exists also during summer. Moreover, it is unclear whether such bias affects attention, memory, or both. In this study, we investigated 110 individuals in summer, 34 of whom reported suffering from low mood during winter, according to the seasonal pattern assessment questionnaire. While the electroencephalogram was recorded, participants learned 60 emotional pictures and subsequently were asked to recognize them in an old/new task. There were no clear group differences in behavioral measures, and no brain response differences in frontal alpha power during learning. During recognition, at 100-300 ms post stimulus individuals with higher seasonality scores exhibited larger alpha power in response to negative as compared to neutral stimuli, while individuals with low seasonality scores exhibited larger alpha power in response to positive as compared to neutral stimuli. While we cannot draw conclusions whether this is an effect of attention or memory, the finding suggests that early cognitive processes are altered already during summer in individuals with increased likelihood to experience SAD during winter. Our data provide evidence for an all-year-round cognitive vulnerability in this population.

Memory Can Define Individual Beliefs and Identity—and Shape Society

Memory profoundly define individual beliefs and identity, shaping how societies make decisions. Five key memory phenomena include—first impressions and the primacy effect, risky decision-making and memory availability, information reliability and source memory, music preferences and the reminiscence bump, and long-term planning and episodic future thinking. Each phenomenon is explored for its impact on policy, revealing the profound ways that memory biases and processes shape critical societal choices, such as judicial decisions, hiring practices, financial planning, and pro-environmental behavior. Although memory's importance in daily life is widely recognized, its central role in shaping self-identity and influencing societal structures is often underestimated. Memory biases, evident in various aspects, from cultural exposures to decision-making heuristics, play a pivotal role in individual and collective behavior. These biases, often manifesting subtly, guide the formation of beliefs and preferences, with strong implications for policy making. Taken together, this work advocates for a multidisciplinary approach to bridge memory theory and policy practice.

The Effect of Rumination on the Stability of Intimate Relationships

The primary purpose of this investigation is to understand the affect of rumination on intimacy and satisfaction. Many previous studies have found that sharing good memories between partners can make their intimate relationships more stable. Therefore, this paper proposes a hypothesis that rumination will destroy the stability of the partnership and reduce intimacy. In this study, Sojump was used to survey 252 Internet users, including 107 males and 145 females. Three questionnaires were used: Rumination Reflection Questionnaire (RRQ), Relationship Assessment Scale and Relationship Closeness Inventory. Correlation analysis and ANOVA were carried out on the data to analyze the relationship between gender, age and 5 variables. The results showed that rumination and future plans with partners showed a significant positive relationship, so it can be considered that rumination and partner intimacy have a positive relationship. In addition, significant negative correlation between age and rumination. The limitation is that the age range of the sample is relatively concentrated, the selected statistical method only shows correlation, and cannot directly reflect its causal relationship, and the questionnaire is based on individual self-report, which may be affected by subjectivity and memory bias. Future research could focus on the reasons for the positive relationship between rumination and partner planning for the future or the relationship between rumination and relationship satisfaction.

Enhanced memory for negative words is associated with amnestic mild cognitive impairment and in vivo cerebral amyloid‐β burden independently of depression

AbstractBackgroundEmotion dysregulation was studied as a potential risk marker for Alzheimer’s disease (AD) by assessing emotional memory in high AD‐risk groups characterized by the presence of mild cognitive impairment (MCI) or remitted major depressive disorder (rMDD) and by evaluating the relationship between emotional memory and in vivo cerebral amyloid‐β deposition.Method435 participants enrolled in the PACt‐MD clinical trial of cognitive remediation plus transcranial direct current stimulation were evaluated at baseline. The sample included 127 older adults with amnestic mild cognitive impairment (aMCI), 51 non‐amnestic MCI (naMCI), 60 rMDD without MCI, 81 rMDD+aMCI, 42 rMDD+naMCI, and 74 cognitively unimpaired older adults (CU). Diagnoses were established during a consensus conference based on psychiatric, medical, and neuropsychological assessment. Emotional memory was assessed by evaluating immediate and short‐term delayed recall of 15 personality adjectives (5 each of positive, negative and neutral words) from the Emotional Verbal Learning Test (Mah et al., 2017, American Journal of Geriatric Psychiatry, 25:1160). A subset (N = 167) completed a Positron Emission Tomography (PET) scan with carbon‐11 Pittsburgh Compound B ([11C] PIB). Valence and diagnostic group effects on recall were assessed using mixed ANOVA. Regression modelling assessed the association between emotional memory bias and amyloid‐β burden.ResultRelative to CU, both aMCI and rMDD+aMCI groups showed enhanced memory for negative words at immediate recall, which persisted after short delay in the aMCI group only (F(1, 339) = 2.66, p = .048; Figure 1). Enhanced memory for negative words at short delay was predictive of in vivo cerebral amyloid‐β deposition (standardized beta = .117, t = 1.84, p = .067), over and above the contributions of age, sex, Apolipoprotein E genotype, depression diagnosis and symptoms, and long delayed verbal recall (F(4,154) = 25.8, p<.001, R2 = .41; Figure 2).ConclusionThe association between enhanced memory for negative personality adjectives and aMCI replicates earlier work in single‐domain aMCI (Mah et al., 2017) and suggests that aMCI is characterized by a negativity bias in memory. These findings, taken together with the relationship between a negativity bias in memory and amyloid‐β burden, suggest that emotion dysregulation, in the form of enhanced memory for negative information, is a potential marker of AD risk.

Disruption of Anterior Temporal Lobe Reduces Distortions in Memory From Category Knowledge.

Memory retrieval does not provide a perfect recapitulation of past events, but instead an imperfect reconstruction of event-specific details and general knowledge. However, it remains unclear whether this reconstruction relies on mixtures of signals from different memory systems, including one supporting general knowledge. Here, we investigate whether the anterior temporal lobe (ATL) distorts new memories because of prior category knowledge. In this preregistered experiment (n = 36), participants encoded and retrieved image-location associations. Most images' locations were clustered according to their category, but some were in random locations. With this protocol, we previously demonstrated that randomly located images were retrieved closer to their category cluster relative to their encoded locations, suggesting an influence of category knowledge. We combined this procedure with TMS delivered to the left ATL before retrieval. We separately examined event-specific details (error) and category knowledge (bias) to identify distinct signals attributable to different memory systems. We found that TMS to ATL attenuated bias in location memory, but this effect was limited to exploratory analyses of atypical category members of animal categories. The magnitude of error was not impacted, suggesting that a memory's fidelity can be decoupled from its distortion by category knowledge. This raises the intriguing possibility that retrieval is jointly supported by separable memory systems.

Sex / gender bias on the Face‐Name Associative Memory Exam in clinically‐normal older adults

AbstractBackgroundMany studies of memory in older adults report a sex difference, usually with female participants scoring slightly better than males. These sex differences may be partially due to the content of the tests, with some content being more memorable to males or females (https://doi.org/10.1093/ARCLIN/ACAC102). We investigated whether male and female older adults show differences on the Face‐Name Associative Memory Exam (FNAME‐12, designed to detect subtle Alzheimer’s disease‐related memory impairment). Specifically, do they show a bias towards remembering the stimuli that match their own sex?MethodParticipants (n = 432, see Table 1) in ‘Insight 46’, a sub‐study of the MRC National Survey of Health and Development (British 1946 birth cohort), completed FNAME‐12 (version A) at age ∼73 years. Stimuli comprise six male and six female faces (presented in alternating order), with names and occupations. Recall is tested four times after various delay intervals. Four total scores were calculated across all recall trials: female names; female occupations; male names; male occupations. We fitted multivariable regression models using Generalised Estimating Equations to investigate effects of item type (name/occupation), item gender (male/female) and participant sex (male/female), and interactions between these variables, controlling for age, education, socioeconomic position and prospectively‐collected childhood cognitive ability.ResultWomen outperformed men (coefficient averaged across the four conditions = 2.2 points [95% CIs 1.3, 3.1], p<0.001) (Fig1; Fig2). This difference was exaggerated for female stimuli (interaction coefficient = 2.0 [1.4, 2.6], p<0.001), and female stimuli occupations (3‐way interaction coefficient = 0.8 [‐0.0, 1.6] p = 0.050) i.e. women scored better than men even on male names, whereas men were particularly disadvantaged at recalling information associated with female stimuli, especially their occupations (Fig2).ConclusionWe found evidence of a gender bias on FNAME‐12 among male participants, where their recall was worse for female stimuli compared to male stimuli, which may partially explain their poorer performance on this test. Such biases should be considered when interpreting sex differences on memory tests. Further analyses before the conference will investigate longitudinal FNAME‐12 performance over ∼2.4 years, to explore whether this memory bias remains constant, or whether it may be a marker of memory decline (potentially reflecting increased reliance on the relatability of test content).

Social Media and Human Behaviour: How Social Media has Exacerbated Myopic Perspectives among Individuals and How can we Tackle it

This paper investigates the impact of social media on human behaviour, specifically focusing on the exacerbation of myopic perspectives among individuals. Social media platforms, driven by algorithmic systems and filter bubbles, have created a digital landscape that reinforces pre-existing beliefs, fosters echo chambers, and hinders exposure to diverse viewpoints. This myopic environment, characterised by selective interpretation and biased memory, has significant implications for societal discourse, and polarising opinions. To tackle this issue, various strategies can be employed, including raising awareness about algorithmic bias, promoting media literacy and critical thinking skills, fostering open dialogue across diverse communities, and encouraging platform design changes that prioritise balanced content curation. By understanding and addressing the adverse effects of social media, we can strive towards a more inclusive, informed, and intellectually vibrant digital ecosystem.
