RESUMO

Self-identification as a victim of violence may lead to increased negative emotions and stress and thus, may change both structure and function of the underlying neural network(s). In a trans-diagnostic sample of individuals who identified themselves as victims of violence and a matched control group with no prior exposure to violence, we employed a social exclusion paradigm, the Cyberball task, to stimulate the re-experience of stress. Participants were partially excluded in the ball-tossing game without prior knowledge. We analyzed group differences in brain activity and functional connectivity during exclusion versus inclusion in exclusion-related regions. The victim group showed increased anger and stress levels during all conditions. Activation patterns during the task did not differ between groups but an enhanced functional connectivity between the IFG and the right vmPFC distinguished victims from controls during exclusion. This effect was driven by aberrant connectivity in victims during inclusion rather than exclusion, indicating that victimization affects emotional responses and inclusion-related brain connectivity rather than exclusion-related brain activity or connectivity. Victims may respond differently to the social context itself. Enhanced negative emotions and connectivity deviations during social inclusion may depict altered social processing and may thus affect social interactions.

RESUMO

INTRODUCTION: Unplanned reactive aggressive acts are a clinical feature of particular interest in patients with borderline personality disorder (BPD). The early identification of personality traits correlated to aggressive behavior is certainly desirable in BDP populations. This study analyzes a clinical sample of 122 adult outpatients with BPD referred to Adult Mental Health Services of the Department of Mental Health of Bologna, in Italy. METHODS: The study examines the relationship with personality facets of the DSM-5 alternative model for personality disorders (AMPD), Personality Inventory for DSM (PID-5), with respect to the four main components of aggression measured by the Aggression Questionnaire (AQ): hostility, anger, verbal and physical aggression. Using robust regression models, the relationships between PID-5 facets and domains and the aggression components under consideration were identified. RESULTS: Verbal and physical aggression in our sample of BPD outpatients is mainly associated to PID-5 antagonism domain. Physically aggressive behavior is also related to callousness facet. CONCLUSIONS: The traits most consistently associated with aggression were the domain of Antagonism and the facet of Hostility. The study findings highlight the need for clinicians working with individuals with BPD to pay particular attention to traits of hostility, callousness, and hostility to understand aggression.

RESUMO

OBJECTIVE: The Minnesota Multiphasic Personality Inventory (MMPI) instruments have a long history with respect to the assessment of psychopathic personality traits. The most recent version, the MMPI-3, should be in a good position to continue this tradition, and the aim of the current research was to evaluate its scales for this purpose. We examined, on the basis of previous research, how well conceptually relevant MMPI-3 scales mapped onto dominant contemporary psychopathy models: the traditional three-factor model and triarchic psychopathy model. HYPOTHESES: We hypothesized that MMPI-3 markers of internalizing would be negatively correlated with boldness, whereas broad and specific markers of externalizing proclivities would be associated with disinhibition and antisociality. We also hypothesized that egocentricity and callousness would be associated with MMPI-3 scales measuring various features of externalizing, interpersonal aggression/antagonism, and grandiosity. METHOD: We used archival samples of male prison inmates (n = 452), community members with externalizing proclivities (n = 205), and university students (n = 645). These participants completed the Expanded Levenson Self-Report Psychopathy Scale and the Triarchic Psychopathy Measure. RESULTS: Zero-order correlation analyses indicated support for many of our hypotheses across samples, with notable exceptions. Regression and dominance analyses yielded information about the most potent MMPI-3 predictors of each psychopathy domain, with consistency across the three samples. Boldness was associated with low scores on Emotional/Internalizing Dysfunction, Low Positive Emotions, Shyness, and Negative Emotionality/Neuroticism and high scores on Self-Importance and Dominance. For meanness and disinhibition, we found substantial overlap with MMPI-3 scales (e.g., Behavioral/Externalizing Dysfunction, Antisocial Behavior). Meanness was indicated by high Aggression, Cynicism, Aggressiveness, and Disaffiliativeness; disinhibition/antisociality was primarily marked by high Antisocial Behavior, Hypomanic Activation, Impulsivity, and Disconstraint; and Anger Proneness, Aggression, and Cynicism were secondary indicators. CONCLUSIONS: These findings provide support for using the MMPI-3 in clinical assessments to corroborate other sources of information regarding psychopathy as well as generate hypotheses for further consideration.

RESUMO

The perception of facial expression plays a crucial role in social communication, and it is known to be influenced by various facial cues. Previous studies have reported both positive and negative biases toward overweight individuals. It is unclear whether facial cues, such as facial weight, bias facial expression perception. Combining psychophysics and event-related potential technology, the current study adopted a cross-adaptation paradigm to examine this issue. The psychophysical results of Experiments 1A and 1B revealed a bidirectional cross-adaptation effect between overweight and angry faces. Adapting to overweight faces decreased the likelihood of perceiving ambiguous emotional expressions as angry compared to adapting to normal-weight faces. Likewise, exposure to angry faces subsequently caused normal-weight faces to appear thinner. These findings were corroborated by bidirectional event-related potential results, showing that adaptation to overweight faces relative to normal-weight faces modulated the event-related potential responses of emotionally ambiguous facial expression (Experiment 2A); vice versa, adaptation to angry faces relative to neutral faces modulated the event-related potential responses of ambiguous faces in facial weight (Experiment 2B). Our study provides direct evidence associating overweight faces with facial expression, suggesting at least partly common neural substrates for the perception of overweight and angry faces.

RESUMO

INTRODUCTION: The majority of people experience anger at some point in their lives when confronted with unpleasant situations. In social settings, anger can lead to aggressive and hostile in the absence of adequate social competences. Our study aims to examine the moderating role of perceived social competences in the association between psychological distress and anger expression (trait anger, hostility, physical aggression, and verbal aggression) among a sample of Lebanese adults. METHODS: 403 participants above 18 years (the mean age was 24.56 ± 8.46) were enrolled in the cross-sectional study with 73% female participants. The candidates were asked to complete a structured questionnaire including the following scales: (1) Buss-Perry Aggression Questionnaire-Short Form (BPAQ-SF), (2) the Depression Anxiety Stress Scale (DASS-8), (3) Perceived Social Competencies (PSC), and (4) The De Jong-Gierveld Loneliness Scale. RESULTS: The interaction psychological distress by perceived social competence was not significantly associated with physical aggression, verbal aggression, or hostility but was significantly associated with anger. After adjusting the results over variables that showed a p <.25 in the bivariate analysis, this association was significant at low (Beta = 0.24; p <.001), moderate (Beta = 0.20; p <.001) and high (Beta = 0.16; p <.001) levels of perceived social competencies, where higher psychological distress was significantly associated with more anger. On another note, with higher perceived social competence, we find a decrease in levels of psychological distress in our sample. CONCLUSION: This study provided evidence that perceived social competencies such as communication skills, empathy and prosocial behaviors act as moderators in the association between psychological distress and anger. In future works, investigating and building advanced program in order to develop social competences of individuals might prove important. It is crucial to implement such strategies and projects in schools: this educational setting could be fruitful in a way that social skills could be instilled during childhood and anger-aggressive behaviors could be managed throughout adulthood.

RESUMO

Former United States President Ronald Reagan's use of media and his charismatic connection with viewers earned him the moniker "the great communicator". One aspect of his charisma, the influence of elicited laughter, during a highly critical 5-minute news story by CBS reporter Leslie Stahl during the 1984 US presidential election is examined here. Two experiments examining the effects of audience laughter on perceptions of charismatic leadership are reported. In the first experiment the effects of audience laughter in response to Reagan's comments were investigated. Here, Reagan's perceived warmth as an effective leader significantly diminished when strong laughter is removed, whereas perceptions of competence remained unaffected. The second study carried out on an older cohort replicated and extended the first in a pre-registered design by considering the perception of trait charisma. Here, the presence or absence of audience laughter did not affect judgements of charisma. Additionally, the affective response before, and then after, the presentation of the news story was measured. Emotions associated with a positive appraisal all decreased after being shown the news story while emotions associated negative appraisal all increased. However, only participant anger was significantly increased when audience laughter was removed. Taken together the findings of both studies converge on the fact that subtle changes in media presentation of political leaders can have a significant effect on viewers. The findings show that even after 40 years in office the social psychological effects of presidential charisma can still influence observers.

RESUMO

BACKGROUND: In recent decades, there has been a significant transformation in the world of work that is characterized by a shift from traditional manufacturing and managerial capitalism, which offered stable full-time employment, to new forms of entrepreneurial capitalism. This new paradigm involves various forms of insecure, contingent, and non-standard work arrangements. Within this context, there has been a noticeable rise in Self-Employed individuals, exhibiting a wide range of -working arrangements. Despite numerous investigations into the factors driving individuals towards Self-Employment and the associated uncertainties and insecurities impacting their lives and job prospects, studies have specifically delved into the connection between the precarious identity of Self-Employed workers and their overall health and well-being. This exploratory study drew on a 'precarity' lens to make contributions to knowledge about Self-Employed workers, aiming to explore how their vulnerable social position might have detrimental effects on their health and well-being. METHODS: Drawing on in-depth interviews with 24 solo Self-Employed people in Ontario (January - July 2021), narrative thematic analysis was conducted based on participants' narratives of their work experiences. The dataset was analyzed with the support of NVIVO qualitative data analysis software to elicit narratives and themes. FINDINGS: The findings showed that people opt into Self-Employment because they prefer flexibility and autonomy in their working life. However, moving forward, in the guise of flexibility, they encounter a life of precarity, in terms of job unsustainability, uncertainties, insecurities, unstable working hours and income, and exclusion from social benefits. As a result, the health and well-being of Self-Employed workers are adversely affected by anger, anomie, and anxiety, bringing forward potential risks for a growing population. CONCLUSION AND IMPLICATIONS: Neoliberalism fabricates a 'precariat' Self-Employed class. This is a social position that is vague, volatile, and contingent, that foreshadows potential threats of the health and wellbeing of a growing population in the changing workforce. The findings in this research facilitate some policy implications and practices at the federal or provincial government level to better support the health and wellbeing of SE'd workers.

RESUMO

Experiencing victimization or mistreatment often induces feelings of anger. The catharsis hypothesis suggests that venting anger may aid in alleviating these negative emotions. Although this hypothesis has faced criticism, therapeutic interventions rooted in catharsis are employed to assist victims in managing their anger. One notable application of the catharsis principle in psychotherapeutic practice with victims involves engaging in aggressive fantasies: Victims who harbor aggressive fantasies against their offenders are supported in working with these fantasies to navigate the complex emotions arising from their victimization. Research investigating the effects of aggressive fantasizing on victims has yielded inconsistent findings, with some studies indicating positive and others suggesting negative outcomes. Herein, we examine whether (instructed) aggressive fantasizing diminishes (catharsis hypothesis) or heightens (escalation hypothesis) subsequent aggressive inclinations compared to non-aggressive fantasizing. Additionally, the moderating role of victims' dispositional tendencies to express anger, specifically Anger Expression-out and Anger Expression-control, in the relationship between aggressive fantasizing and aggressive inclinations was examined. We recruited individuals (N = 245) who had experienced victimization through highly unfair treatment and instructed them to imagine confronting their wrongdoer using either aggressive or non-aggressive communication. Participants then reported their aggressive inclinations. Data supported the escalation hypothesis, revealing that aggressive fantasizing amplifies subsequent aggressive inclinations. Importantly, individuals with higher Anger Expression-out demonstrated greater susceptibility to this effect; whereas, Anger Expression-control did not moderate the link between aggressive fantasizing and inclinations. These findings further challenge the catharsis hypothesis and underscore the role of dispositional anger expression tendencies on the effects of aggressive fantasizing.

RESUMO

Anger is an unpleasant emotion that most people want to get rid of. Some anger management activities focus on decreasing arousal (e.g., deep breathing, mindfulness, meditation), whereas others focus on increasing arousal (e.g., hitting a bag, jogging, cycling). This meta-analytic review, based on 154 studies including 184 independent samples involving 10,189 participants, tested the effectiveness of both types of activities. The results indicated that arousal-decreasing activities decreased anger and aggression (g = -0.63, [-0.82, -0.43]), and the results were robust. Effects were stable over time for participants of different genders, races, ages, and cultures. Arousal-decreasing activities were effective in students and non-students, in criminal offenders and non-offenders, and in individuals with and without intellectual disabilities. Arousal-decreasing activities were effective regardless of how they were delivered (e.g., digital platforms, researchers, therapists), in both group and individual sessions, and in both field and laboratory settings. In contrast, arousal-increasing activities were ineffective overall (g = -0.02, [-0.13, 0.09]) and were heterogenous and complex. These findings do not support the ideas that venting anger or going for a run are effective anger management activities. A more effective approach for managing anger is "turning down the heat" or calming down by engaging in activities that decrease arousal.

RESUMO

Autistic individuals generally demonstrate impaired emotion recognition but it is unclear whether effects are emotion-specific or influenced by oxytocin receptor (OXTR) genotype. Here we implemented a dimensional approach using an implicit emotion recognition task together with functional MRI in a large cohort of neurotypical adult participants (N = 255, male = 131, aged 17-29 years) to establish associations between autistic traits and neural and behavioral responses to specific face emotions, together with modulatory effects of OXTR genotype. A searchlight-based multivariate pattern analysis (MVPA) revealed an extensive network of frontal, basal ganglia, cingulate and limbic regions exhibiting significant predictability for autistic traits from patterns of responses to angry relative to neutral expression faces. Functional connectivity analyses revealed a genotype interaction (OXTR SNPs rs2254298, rs2268491) for coupling between the orbitofrontal cortex and mid-cingulate during angry expression processing, with a negative association between coupling and autistic traits in the risk-allele group and a positive one in the non-risk allele group. Overall, results indicate extensive emotion-specific associations primarily between patterns of neural responses to angry faces and autistic traits in regions processing motivation, reward and salience but not in early visual processing. Functional connections between these identified regions were not only associated with autistic traits but also influenced by OXTR genotype. Thus, altered patterns of neural responses to threatening faces may be a potential biomarker for autistic symptoms although modulatory influences of OXTR genotype need to be taken into account.

RESUMO

For undergraduate pharmacy students, the first step of antimicrobial stewardship learning objectives is to integrate antimicrobial knowledge from the foundational sciences. We hypothesised that using a multidisciplinary approach including two sessions of tutorials could be relevant in term of students' interest, satisfaction and learning retention time. The evaluation of students' feelings was based on a questionnaire including different dimensions and three focus groups with four students. Quantitative data were analysed with the EPI-INFO 7.2 software and a thematic analysis was implemented for qualitative data by using NVivo 12 software. The evaluation of students' learning concerned both short-time learning retention (STLR) and medium-time learning retention (MTLR), six months after the last session. Overall, 63 students responded to the questionnaire. Most of them appreciated the tutorials according to the different dimensions envisaged. Focus groups confirmed the interest of students for the multidisciplinary approach, interactions with teachers and opportunities of learning transfers. Concurrently, a lack of self-efficacy, low confidence towards the other students, external regulation of motivation and poor autonomy were recorded for some participants. Finally, there was no significant decrease between the scores of the STLR assessment and those of the MTLR assessment (58.5 ± 12.1/100 and 54.4 ± 8.9/100, respectively).

RESUMO

Activation of the Wnt signalling pathway is vital in the anterior-posterior patterning during neural development. In a new study, Stephane Angers and colleagues leverage previously developed selective antibodies against Frizzled receptors of the Wnt pathway to stimulate midbrain progenitor differentiation in human pluripotent stem cells. We caught up with first author Andy Yang and corresponding author Stephane Angers, Professor at the University of Toronto, to learn more about the story behind the paper.

RESUMO

This study aimed to investigate whether attentional bias to threat, commonly observed in clinically anxious children, also manifests in healthy children, potentially aiding the early detection of at-risk individuals. Additionally, it sought to explore the moderating role of parent-child attachment security on the association between vulnerability factors (anxiety sensitivity, intolerance of uncertainty, perseverative cognitions) as indicators of vulnerability to anxiety, and attentional bias towards threat in healthy children. A total of 95 children aged 8 to 12 years completed the Visual Search Task to assess attentional bias. Vulnerability to anxiety was measured using a composite score derived from the Childhood Anxiety Sensitivity Index, Intolerance of Uncertainty Scale for Children, and Perseverative Thinking Questionnaire. Parent-child attachment security was assessed using the Security Scale-Child Self-Report. Analyses revealed that higher vulnerability to anxiety was associated with faster detection of anger-related stimuli compared to neutral ones, and this association was further influenced by high maternal security. These findings in healthy children suggest an interaction between specific factors related to anxiety vulnerability and the security of the mother-child relationship, leading to cognitive patterns resembling those seen in clinically anxious individuals. These results hold promise for early identification of children at risk of developing anxiety disorders.

RESUMO

This study aims to examine the mediating role of self-efficacy (SE) and self-control (SC) in the relationship between physical activity (PA) and aggressive behaviors (AB) among college students. It provides a basis for the prevention and control of AB among college students. This study employed a survey research methodology, including the PA Level Scale, the General Self-efficacy Scale, the Self-control Scale, and the Chinese Aggressive Behaviors Scale on 950 college students. The chain mediating effect test and Bootstrap analysis were applied. The results were as follows: (1) There was a main effect of PA on SE, SC, and AB as well as all sub-indicators (physical aggression, verbal aggression, anger, hostility, self-directed aggression), i.e., PA had a direct effect on the control of all three; (2) PA level was significantly negatively correlated with AB and significantly positively correlated with SE and SC. That is, the higher the level of PA, the better the SE and SC, and the lower the probability of AB; (3) The three pathways had mediating effects: PA → SE → AB, PA → SC → AB, PA → SE → SC → AB, with effect sizes of 8.78%, 28.63%, and 19.08%, respectively. It is concluded that regular PA is a potent method for decreasing aggressive behavior and psychological issues in university students while additionally promoting self-efficacy and self-control. Increasing the intensity of PA may enhance the effectiveness of these chain benefits.

RESUMO

BACKGROUND: Emotion processing deficits are known to accompany depressive symptoms and are often seen in stroke patients. Little is known about the influence of post-stroke depressive (PSD) symptoms and specific brain lesions on altered emotion processing abilities and how these phenomena develop over time. This potential relationship may impact post-stroke rehabilitation of neurological and psychosocial function. To address this scientific gap, we investigated the relationship between PSD symptoms and emotion processing abilities in a longitudinal study design from the first days post-stroke into the early chronic phase. METHODS: Twenty-six ischemic stroke patients performed an emotion processing task on videos with emotional faces ('happy,' 'sad,' 'anger,' 'fear,' and 'neutral') at different intensity levels (20%, 40%, 60%, 80%, 100%). Recognition accuracies and response times were measured, as well as scores of depressive symptoms (Montgomery-Åsberg Depression Rating Scale). Twenty-eight healthy participants matched in age and sex were included as a control group. Whole-brain support-vector regression lesion-symptom mapping (SVR-LSM) analyses were performed to investigate whether specific lesion locations were associated with the recognition accuracy of specific emotion categories. RESULTS: Stroke patients performed worse in overall recognition accuracy compared to controls, specifically in the recognition of happy, sad, and fearful faces. Notably, more depressed stroke patients showed an increased processing towards specific negative emotions, as they responded significantly faster to angry faces and recognized sad faces of low intensities significantly more accurately. These effects obtained for the first days after stroke partly persisted to follow-up assessment several months later. SVR-LSM analyses revealed that inferior and middle frontal regions (IFG/MFG) and insula and putamen were associated with emotion-recognition deficits in stroke. Specifically, recognizing happy facial expressions was influenced by lesions affecting the anterior insula, putamen, IFG, MFG, orbitofrontal cortex, and rolandic operculum. Lesions in the posterior insula, rolandic operculum, and MFG were also related to reduced recognition accuracy of fearful facial expressions, whereas recognition deficits of sad faces were associated with frontal pole, IFG, and MFG damage. CONCLUSION: PSD symptoms facilitate processing negative emotional stimuli, specifically angry and sad facial expressions. The recognition accuracy of different emotional categories was linked to brain lesions in emotion-related processing circuits, including insula, basal ganglia, IFG, and MFG. In summary, our study provides support for psychosocial and neural factors underlying emotional processing after stroke, contributing to the pathophysiology of PSD.

RESUMO

This study explores the effectiveness of Explainable Artificial Intelligence (XAI) for predicting suicide risk from medical tabular data. Given the common challenge of limited datasets in health-related Machine Learning (ML) applications, we use data augmentation in tandem with ML to enhance the identification of individuals at high risk of suicide. We use SHapley Additive exPlanations (SHAP) for XAI and traditional correlation analysis to rank feature importance, pinpointing primary factors influencing suicide risk and preventive measures. Experimental results show the Random Forest (RF) model is excelling in accuracy, F1 score, and AUC (>97% across metrics). According to SHAP, anger issues, depression, and social isolation emerge as top predictors of suicide risk, while individuals with high incomes, esteemed professions, and higher education present the lowest risk. Our findings underscore the effectiveness of ML and XAI in suicide risk assessment, offering valuable insights for psychiatrists and facilitating informed clinical decisions.

RESUMO

This article is part of a study aimed to map antiracist knowledge and practices in mental health by monitoring the practices of three collectives of professionals working in/with the psychosocial care network in the city of São Paulo, allowing us to characterize their intervention strategies. To contribute to the conceptualization of this article, through a review of the decolonial literature, three major ideas have been outlined that have allowed us to give substance to the decolonization of Psychiatric Reform: bewilderment, which, in dialogue with Achille Mbembe and Frantz Fanon, invites us to affirm madness and blackness without, however, establishing fixations; the antimanicolonial, which occurs in the promotion of the free and countercultural exercise of imagining diasporas, in light of that proposed by Édouard Glissant, Paul Gilroy, and Lélia Gonzales regarding an Atlantic (de)orientation in which elements of the black diaspora and Latin America can re-signify blackness and unreason; and aquilombar, as a liberatory praxis whose genesis lies in the quilombos as a living metaphor for the radicalisation of relationships in differences, based on Abdias do Nascimento's quilombismo, Clóvis Moura's quilombagem, Beatriz Nascimento's (k)quilombo, and Mariléa de Almeida's devir quilomba.


Este artigo é parte de uma pesquisa que buscou cartografar saberes e fazeres antirracistas em saúde mental por meio do acompanhamento das práticas de três coletivos de profissionais trabalhando na/com a rede de atenção psicossocial na cidade de São Paulo, o que possibilitou caracterizar suas estratégias de intervenção. Buscando contribuir para sua conceitualização, delineamos, por meio da revisão da literatura descolonial, três ideias-força que nos permitem dar corpo à descolonização da Reforma Psiquiátrica: o desnortear, que, em diálogo com Achille Mbembe e Frantz Fanon, nos convida à afirmação da loucura e da negritude - sem, no entanto, estabelecer fixações; o antimanicolonial, que se dá no fomento do exercício livre e contracultural de imaginar diásporas, em relação com as proposições de Édouard Glissant, Paul Gilroy e Lélia Gonzales quanto a uma (des)orientação atlântica na qual elementos da diáspora negra e da América Latina possam ressignificar negritude e desrazão; e o aquilombar, como práxis libertária que tem em sua gênese os quilombos como metáfora viva da radicalização das relações nas diferenças, a partir do quilombismo de Abdias do Nascimento, da quilombagem de Clóvis Moura, do (k)quilombo de Beatriz Nascimento e do devir quilomba de Mariléa de Almeida.

RESUMO

When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions.
