Autobiographical memory and social skills of men and women

The Impact of Emotion and Sex on Fabrication and False Memory Formation

The aim of the present study was to examine how negative emotion and sex affect self-generated errors as in fabrication set-up and later false recognition of those errors. In total, 120 university students volunteered to take part in the study. Participants were assigned at random into two equal sized groups (N = 60) depending on the type of event they received (negative emotional or neutral). We expected that fabrication and false recognition would be enhanced for the emotional event compared to the neutral one. We further hypothesized that both the willingness to fabricate and later false recognition would be enhanced for women compared with men. The results partly confirmed the hypotheses. The results showed that emotional valence (negative) affects both the willingness to fabricate about events that never took place, and the recognition of the fabrication as true at a later point. Women and men were equally likely to fabricate but women were more likely to recognize their fabrication, particularly for the emotional event. The results are discussed in the context of prior work.

The Effect of Social Anxiety on the Risk of Sexual Victimization via Assertiveness in an Ethnically Diverse Sample

Preliminary evidence suggests social anxiety may increase the risk of sexual victimization via decreased sexual assertiveness. A sample of 2,043 undergraduate students completed an online survey. Analyses of moderated indirect effects examined whether gender or ethnicity moderated the indirect effect of social anxiety on sexual victimization via sexual assertiveness. No moderation effects were found, but the indirect effect of social anxiety on sexual victimization via sexual assertiveness was significant for all five types of sexual victimization. Clinically, the findings suggest that sexual assault risk reduction programs may be improved by including assertive resistance strategies and behavioral rehearsals.

Gender identity better than sex explains individual differences in episodic and semantic components of autobiographical memory: An fMRI study

Advances in the literature of sex-related differences in autobiographical memory increasingly tend to highlight the importance of psychosocial factors such as gender identity, which may explain these differences better than sex as a biological factor. To date, however, none of these behavioral studies have investigated this hypothesis using neuroimaging. The purpose of this fMRI study is to examine for the first time sex and gender identity-related differences in episodic and semantic autobiographical memory in healthy participants (M=19, W=18). No sex-related differences were found; however, sex-related effects of masculine and feminine gender identity were identified in men and women independently. These results confirm the hypothesis that differences in episodic and semantic autobiographical memory are best explained by gender but are an interaction between biological sex and gender identity and extend these findings to the field of neuroimaging. We discuss the importance of hormonal factors to be taken into consideration in the future.

Biological Sex and Sex Hormone Impacts on Deficits in Episodic-Like Memory in a Rat Model of Early, Pre-motor Stages of Parkinson's Disease

Episodic memory deficits are among the earliest appearing and most commonly occurring examples of cognitive impairment in Parkinson's disease (PD). These enduring features can also predict a clinical course of rapid motor decline, significant cognitive deterioration, and the development of PD-related dementia. The lack of effective means to treat these deficits underscores the need to better understand their neurobiological bases. The prominent sex differences that characterize episodic memory in health, aging and in schizophrenia and Alzheimer's disease suggest that neuroendocrine factors may also influence episodic memory dysfunction in PD. However, while sex differences have been well-documented for many facets of PD, sex differences in, and sex hormone influences on associated episodic memory impairments have been less extensively studied and have never been examined in preclinical PD models. Accordingly, we paired bilateral neostriatal 6-hydroxydopamine (6-OHDA) lesions with behavioral testing using the What-Where-When Episodic-Like Memory (ELM) Task in adult rats to first determine whether episodic-like memory is impaired in this model. We further compared outcomes in gonadally intact female and male subjects, and in male rats that had undergone gonadectomy—with and without hormone replacement, to determine whether biological sex and/or sex hormones influenced the expression of dopamine lesioned-induced memory deficits. These studies showed that 6-OHDA lesions profoundly impaired recall for all memory domains in male and female rats. They also showed that in males, circulating gonadal hormones powerfully modulated the negative impacts of 6-OHDA lesions on What, Where, and When discriminations in domain-specific ways. Specifically, the absence of androgens was shown to fully attenuate 6-OHDA lesion-induced deficits in ELM for “Where” and to partially protect against lesion-induced deficits in ELM for “What.” In sum, these findings show that 6-OHDA lesions in rats recapitulate the vulnerability of episodic memory seen in early PD. Together with similar evidence recently obtained for spatial working memory, the present findings also showed that diminished androgen levels provide powerful, highly selective protections against the harmful effects that 6-OHDA lesions have on memory functions in male rats.

Autobiographical recall of mastery experiences is a mechanism of self-affirming under social identity threat

Autobiographical memories are relevant to many areas of psychological functioning. So far, however, there is no evidence whether personal memories can also be instrumental for self-affirmation. We conducted two experiments, varying national identity threat among U.S. Americans recruited through MTurk. In Study 1, participants spontaneously recalled autobiographical memories after being exposed to varying levels of threat. When the threat was identity-relevant, those who spontaneously recalled mastery autobiographical memories had higher collective self-esteem than those who did not. In Study 2, we instructed participants to recall either mastery autobiographical memories or routine memories. When the threat was identity-relevant, collective self-esteem was again higher for mastery recall compared to routine recall, moderated by national identification and self-esteem. We also found a general, self-affirmative effect of autobiographical memories, regardless of threat relevance or recall content. Findings provide a first empirical demonstration that autobiographical recall can enhance self-affirmation in identity threat situations.

Positive emotional induction interferes with the reconsolidation of negative autobiographical memories, in women only

After reactivation, a previously consolidated memory can enter into a labile state followed by a re-stabilization process defined as reconsolidation. The aim of this study was to explore whether an existing negative autobiographical memory can be modified by using a non-invasive interference (audiovisual positive preparation) after reactivation and to determine if this effect could be dependent on the reconsolidation process. We found that the presentation of a positive inductor after a negative autobiographical memory reactivation may lead to a change in the emotional information of the original trace and that such effect can be mediated by the reconsolidation process. The modification of the memory has been shown in women only. These results suggest that a positive audiovisual induction may play a potential role in psychotherapeutic techniques for the modification of dysfunctional autobiographical memories.

The Social Function of Autobiographical Stories in the Personal and Virtual World: An Initial Investigation

Receiving another's autobiographical story may serve to elicit feelings of liking and empathy for the story sharer. Research has mostly examined social functions of autobiographical stories for in-person communications. The current experiment (N = 60) examined whether levels of liking, closeness, and empathy felt for a stranger (female confederate) after receiving her story depended on if (a) the story was received in-person or through instant message (IM), and (b) the story was positive or negative. Liking and having empathy for the stranger was higher in the in-person conditions compared to IM conditions. This effect was mediated by how engaged participants were with the story. Participants liked the stranger more after receiving the positive autobiographical story, but they felt more empathy toward her after the negative autobiographical story. The discussion considers parameters of the communication platform and people's perceptions of stories as explanations for the results. Limitations are considered.

Association between precuneus volume and autobiographical memory impairment in posterior cortical atrophy: Beyond the visual syndrome

Posterior cortical atrophy is a neurodegenerative syndrome characterised by progressive disruption of visual and perceptual processing, associated with atrophy in the parieto-occipital cortex. Current diagnostic criteria describe relative sparing of episodic memory function, but recent findings suggest that anterograde memory is often impaired. Whether these deficits extend to remote memory has not been addressed. A large body of evidence suggests that the recollection of an autobiographical event from the remote past coincides with the successful retrieval of visual images. We hypothesised that the profound visual processing deficits in posterior cortical atrophy would result in impaired autobiographical memory retrieval. Fourteen posterior cortical atrophy patients, eighteen typical Alzheimer's disease patients and twenty-eight healthy controls completed the Autobiographical Interview. Autobiographical memory in posterior cortical atrophy was characterised by a striking loss of internal, episodic detail relative to controls and to same extent as typical Alzheimer's disease patients, in conjunction with an increase in external details tangential to the memory described. The memory narratives of posterior cortical atrophy patients showed a specific reduction in spatiotemporal and perceptual detail. Voxel-based morphometry analysis revealed atrophy of the parieto-occipital cortices in posterior cortical atrophy but relatively spared hippocampi bilaterally, compared with characteristic atrophy of the medial temporal lobes in typical Alzheimer's disease. Analysis of brain regions showing posterior cortical atrophy-specific atrophy revealed a correlation between perceptual details in autobiographical memory and grey matter density in the right precuneus. This study demonstrates remote memory impairment in posterior cortical atrophy despite relatively preserved medial temporal lobe structures. The results demonstrate, for the first time, profound autobiographical memory impairment in PCA and suggest that this is driven by the well-recognised deficits in higher-order visual processing. The findings are discussed in the context of posterior parietal contributions to imagery and memory, and the clinical implications of autobiographical memory impairment for diagnostic and management protocols in posterior cortical atrophy.

Functions of personal and vicarious life stories: identity and empathy

The present study investigates functions of personal and vicarious life stories focusing on identity and empathy. Two-hundred-and-forty Danish high school students completed two life story questionnaires: one for their personal life story and one for a close other's life story. In both questionnaires, they identified up to 10 chapters and self-rated the chapters on valence and valence of causal connections. In addition, they completed measures of identity disturbance and empathy. More positive personal life stories were related to lower identity disturbance and higher empathy. Vicarious life stories showed a similar pattern with respect to identity but surprisingly were unrelated to empathy. In addition, we found positive correlations between personal and vicarious life stories for number of chapters, chapter valence, and valence of causal connections. The study indicates that both personal and vicarious life stories may contribute to identity.

Children's Vantage Point of Recalling Traumatic Events

This study investigated the recollections of child survivors of the 2004 Asian tsunami in terms of their vantage point and posttraumatic stress disorder (PTSD) responses. Five years after the tsunami, 110 children (aged 7–13 years) living in Aceh, Indonesia were assessed for source of memories of the tsunami (personal memory or second-hand source), vantage point of the memory, and were administered the Children’s Revised Impact of Event Scale-13. Fifty-three children (48%) met criteria for PTSD. Two-thirds of children reported direct memories of the tsunami and one-third reported having memories based on reports from other people. More children (97%) who reported an indirect memory of the tsunami recalled the event from an onlooker’s perspective to some extent than those who recalled the event directly (63%). Boys were more likely to rely on stories from others to reconstruct their memory of the tsunami, and to adopt an observer perspective. Boys who adopted an observer’s perspective had less severe PTSD than those who adopted a field perspective. These findings suggest that, at least in the case of boys, an observer perspectives of trauma can be associated with levels of PTSD.

Sex Differences in the Neural Correlates of Specific and General Autobiographical Memory

Autobiographical memory (AM) underlies the formation and temporal continuity over time of personal identity. The few studies on sex-related differences in AM suggest that men and women adopt different cognitive or emotional strategies when retrieving AMs. However, none of the previous works has taken into account the distinction between episodic autobiographical memory (EAM), consisting in the retrieval of specific events by means of mental time travel, and semantic autobiographical memory (SAM), which stores general personal events. Thus, it remains unclear whether differences in these strategies depend on the nature of the memory content to be retrieved. In the present study we employed functional MRI to examine brain activity underlying potential sex differences in EAM and SAM retrieval focusing on the differences in strategies related to the emotional aspects of memories while controlling for basic cognitive strategies. On the behavioral level, there was no significant sex difference in memory performances or subjective feature ratings of either type of AM. Activations common to men and women during AM retrieval were observed in a typical bilateral network comprising medial and lateral temporal regions, precuneus, occipital cortex as well as prefrontal cortex. Contrast analyses revealed that there was no difference between men and women in the EAM condition. In the SAM condition, women showed an increased activity, compared to men, in the dorsal anterior cingulate cortex, inferior parietal and precentral gyrus. Overall, these findings suggest that differential neural activations reflect sex-specific strategies related to emotional aspects of AMs, particularly regarding SAM. We propose that this pattern of activation during SAM retrieval reflects the cognitive cost linked to emotion regulation strategies recruited by women compared to men. These sex-related differences have interesting implications for understanding psychiatric disorders with differential sex prevalence and in which one of key features is overgenerality in AM.

Empathy and autobiographical memory: are they linked?

Autobiographical memory and empathy have been linked with social interaction variables as well as gender in independent bodies of literature. However a scarcity of research exists on the direct link between autobiographical memory and empathy. Exploring this link, in particular for memory of friendships and empathy, was the authors' main aim. A total of 107 Italian undergraduates participated. A memory fluency task was used to assess accessibility of memories spanning their entire life (preschool through university) and an empathy scale (Italian version of the Interpersonal Reactivity Index) was employed to measure the participants' level and dimensions of empathy. For men, empathy scores were related to how many memories they could recall. Specifically, men with higher scores on the fantasy and empathic concern scales and those with lower scores on the personal distress scales recalled more memories of friends. However, affective quality of their memories was unrelated to empathy. In contrast, for women there was no relationship between number of memories and empathy, but the emotional tone of their memories was related to empathy: those with higher scores on the personal distress scale had proportionately fewer affectively positive memories. Results are discussed in terms of gender differences in both empathy and parental socialization patterns.

Behavioral and neuroanatomical investigation of Highly Superior Autobiographical Memory (HSAM)

A single case study recently documented one woman's ability to recall accurately vast amounts of autobiographical information, spanning most of her lifetime, without the use of practiced mnemonics (Parker, Cahill, & McGaugh, 2006). The current study reports findings based on eleven participants expressing this same memory ability, now referred to as Highly Superior Autobiographical Memory (HSAM). Participants were identified and subsequently characterized based on screening for memory of public events. They were then tested for personal autobiographical memories as well as for memory assessed by laboratory memory tests. Additionally, whole-brain structural MRI scans were obtained. Results indicated that HSAM participants performed significantly better at recalling public as well as personal autobiographical events as well as the days and dates on which these events occurred. However, their performance was comparable to age- and sex-matched controls on most standard laboratory memory tests. Neuroanatomical results identified nine structures as being morphologically different from those of control participants. The study of HSAM may provide new insights into the neurobiology of autobiographical memory.

Autobiographical memory in adults with autism spectrum disorder: The role of depressed mood, rumination, working memory and theory of mind

Autobiographical memory difficulties have been widely reported in adults with autism spectrum disorder (ASD). The aim of the current study was to explore the potential correlates of autobiographical memory performance (including depressed mood, rumination, working memory and theory of mind) in adults with ASD, relative to a group of typical adults matched for age, gender and IQ. Results demonstrated that the adults with ASD reported higher levels of depressed mood and rumination than the typical adults, and also received lower scores on measures of theory of mind and working memory. Correlational analysis suggested that theory of mind and working memory were associated with autobiographical memory performance in the adults with ASD, but no significant relationships were observed between autobiographical memory, depressed mood and rumination in this group. To explore these patterns further, two cases of adults with a dual diagnosis of ASD and depression are discussed. These participants present a profile in line with the idea that depressed mood and rumination do not have the same influence on autobiographical memory in adults with ASD as they do in typical adults.

Gender differences in autobiographical memory for everyday events: retrieval elicited by SenseCam images versus verbal cues

Gender differences are frequently observed in autobiographical memory (AM). However, few studies have investigated the neural basis of potential gender differences in AM. In the present functional MRI (fMRI) study we investigated gender differences in AMs elicited using dynamic visual images vs verbal cues. We used a novel technology called a SenseCam, a wearable device that automatically takes thousands of photographs. SenseCam differs considerably from other prospective methods of generating retrieval cues because it does not disrupt the ongoing experience. This allowed us to control for potential gender differences in emotional processing and elaborative rehearsal, while manipulating how the AMs were elicited. We predicted that males would retrieve more richly experienced AMs elicited by the SenseCam images vs the verbal cues, whereas females would show equal sensitivity to both cues. The behavioural results indicated that there were no gender differences in subjective ratings of reliving, importance, vividness, emotion, and uniqueness, suggesting that gender differences in brain activity were not due to differences in these measures of phenomenological experience. Consistent with our predictions, the fMRI results revealed that males showed a greater difference in functional activity associated with the rich experience of SenseCam vs verbal cues, than did females.

Number of Siblings in Childhood Explains Cultural Variance in Autobiographical Memory in Cameroon, People’s Republic of China, and Germany

In the present study, the authors set out to investigate whether number of siblings as a contextual ontogenetic factor can explain cultural variance in autobiographical memory (AM). After replicating the commonly found cultural differences in AM in samples from Asia (PR China, N = 77), Africa (Cameroon, N = 68), and Europe (Germany, N = 100), the authors demonstrate that the number of siblings has a substantial effect on AM variables. The cultural variance explained by the number of siblings ranges from 30% in the age of first memory to 99% in specificity and integration. These findings (a) point towards the necessity to include contextual variables in the investigation of cultural differences in AM and (b) highlight the importance of sensitive periods in early childhood for the development of AM.

Social performance is more closely associated with theory of mind and autobiographical memory than with psychopathological symptoms in clinically stable patients with schizophrenia-spectrum disorders

The purpose of this study was to examine the association of deficits in theory of mind ability (ToM), deficits in recalling autobiographical memories (AM) and social performance in patients with psychosis. Furthermore, the study aimed to investigate if deficits in ToM and AM are better predictors of social performance than psychopathological symptoms and other neurocognitive variables. In a cross-sectional design, patients with schizophrenia-spectrum disorders (n=55) and healthy controls (n=45) completed a ToM movie paradigm in which they had to infer the characters' intentions and emotions in movies displaying social situations and a first- and second-order false belief ToM paradigm. Recall of AM was investigated using a structured interview. Social performance was assessed in a standardized role-play situation, which was later rated by trained raters, blind to diagnosis. Deficits in AM were associated with deficits in the ability to infer intentions of movie characters and in social performance in patients with schizophrenia-spectrum disorders. ToM ability to infer emotions of movie characters and recalling of AM were better predictors of social performance than psychopathological symptoms and other neurocognitive deficits. The results suggest that interventions aiming to enhance ToM deficits and deficits in AM might result in improvement of social performance.

Brief Report: Self-defining and everyday autobiographical memories in adults with autism spectrum disorders

Autobiographical memory impairments in autism spectrum disorders (ASD) have been attributed to a failure in using the self as an effective memory organisational system. To explore this hypothesis, we compared self-defining and everyday memories in adults with and without ASD. Results demonstrated that both groups were able to distinguish between self-defining and everyday memories, although the ASD group generated fewer specific memories overall. Despite qualitative similarities between the narratives of the two groups, the adults with ASD extracted less meaning from their narratives. Difficulties in eliciting meaning from memories suggests a failure in using past experiences to update the self. We therefore propose that the self-memory relationship might be static, rather than dynamic, in ASD.

The Emergence of the Independent Self: Autobiographical Memory as a Mediator of False Belief Understanding and Sociocultural Motive Orientation in Cameroonian and German Preschoolers

Applying a preschooler version of an instrument measuring implicit motives (Operant Multimotive Test), the authors investigated the interrelations of autobiographical memory, theory of mind, and implicit motives in the preschool years. Four- to 6-year-old children from Bamenda (Cameroon, N = 30) and Osnabrück (Germany, N = 52) were tested using a location false belief task, and a second order task as measures for theory of mind and a version of Wang and Leichtman’s task on children’s narratives as a measure of autobiographical memory coded with the Cognitive Complexity Scoring Manual. Regression analyses for mediator effects while controlling for moderating effects of culture show that cognitive complexity of autobiographical memory mediates the relationship of mentalistic abilities and sociocultural orientation of implicit motivation. Results are discussed within the framework of the independent-interdependent construal of the self.

Sex influences on the neurobiology of learning and memory

In essentially every domain of neuroscience, the generally implicit assumption that few, if any, meaningful differences exist between male and female brain function is being challenged. Here we address how this development is influencing studies of the neurobiology of learning and memory. While it has been commonly held that males show an advantage on spatial tasks, and females on verbal tasks, there is increasing evidence that sex differences are more widespread than previously supposed. Differing performance between the sexes have been observed on a number of common learning tasks in both the human and animal literature, many neither purely spatial nor verbal. We review sex differences reported in various areas to date, while attempting to identify common features of sexually dimorphic tasks, and to place these differences in a neurobiological context. This discussion focuses on studies of four classes of memory tasks for which sex differences have been frequently reported: spatial, verbal, autobiographical, and emotional memory. We conclude that the female verbal advantage extends into numerous tasks, including tests of spatial and autobiographical abilities, but that a small but significant advantage may exist for general episodic memory. We further suggest that for some tasks, stress evokes sex differences, which are not normally observed, and that these differences are mediated largely by interactions between stress and sex hormones.

The impact of gender stereotypes on the evaluation of general practitioners' communication skills: an experimental study using transcripts of physician-patient encounters

OBJECTIVE

The present study has been designed to test for the effect of physicians' gender on the perception and assessment of empathic communication in medical encounters.

METHODS

Eighty-eight volunteers were asked to assess six transcribed interactions between physicians and a standardized patient. The effects of physicians' gender were tested by the experimental manipulation of physicians' gender labels in transcripts. Participants were randomly assigned to one of two testing conditions: (1) perceived gender corresponds to the physician's true gender; (2) perceived gender differs from the physician's true gender. Empathic communication was assessed using the Rating Scales for the Assessment of Empathic Communication in Medical Interviews.

RESULTS

A 2 (physician's true gender: female vs. male)x2 (physician's perceived gender: female vs. male)x2 (rater's gender: female vs. male) mixed multivariate analysis of variance (MANOVA) yielded a main effect for physician's true gender. Female physicians were rated higher on empathic communication than male physicians irrespective of any gender labels.

CONCLUSION

The present findings suggest that gender differences in the perception of physician's empathy are not merely a function of the gender label. These findings provide evidence for differences in male and female physicians' empathic communication that cannot be attributed to stereotype bias.

PRACTICE IMPLICATIONS

Future efforts to evaluate communication skills training for general practitioners may consider gender differences.

Memory for emotional and neutral information: Gender and individual differences in emotional sensitivity

In studies of autobiographical memory, women typically remember more emotional information than do men. The present study evaluated whether women recall more emotional information than men when the content of an event is controlled. Participants read a script containing emotional and neutral information, under instructions to prepare advice for the characters addressing either interpersonal issues (emotional focus), concrete plans (neutral focus), or with no particular topic suggested (undirected focus). After writing out advice, on a surprise memory test women recalled more emotional information than men in all focus conditions with no deficit in neutral recall. Women recalled more neutral information than men in the neutral focus condition. A measure of emotional sensitivity mediated the gender difference in emotional recall suggesting that memory for emotional information is not solely a function of gender.
