RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Suicidal behavior and non-suicidal self-injury (NSSI) are common in adolescent patients with major depressive disorder (MDD). Thus, delineating the unique characteristics of suicide attempters having adolescent MDD with NSSI is important for suicide prediction in the clinical setting. Here, we performed psychological and biochemical assessments of 130 youths having MDD with NSSI. Participants were divided into two groups according to the presence/absence of suicide attempts (SAs). Our results demonstrated that the age of suicide attempters is lower than that of non-attempters in participants having adolescent MDD with NSSI; suicide attempters had higher Barratt Impulsiveness Scale (BIS-11) impulsivity scores and lower serum CRP and cortisol levels than those having MDD with NSSI alone, suggesting levels of cortisol and CRP were inversely correlated with SAs in patients with adolescent MDD with NSSI. Furthermore, multivariate regression analysis revealed that NSSI frequency in the last month and CRP levels were suicidal ideation predictors in adolescent MDD with NSSI, which may indicate that the increased frequency of NSSI behavior is a potential risk factor for suicide. Additionally, we explored the correlation between psychological and blood biochemical indicators to distinguish suicide attempters among participants having adolescent MDD with NSSI and identified a unique correlation network that could serve as a marker for suicide attempters. Our research data further suggested a complex correlation between the psychological and behavioral indicators of impulsivity and anger. Therefore, our study findings may provide clues to identify good clinical warning signs for SA in patients with adolescent MDD with NSSI.

RESUMEN

A person with impaired emotion recognition is not able to correctly identify facial expressions represented by other individuals. The aim of the present study is to assess eyes gaze and facial emotion recognition in a healthy population using dynamic avatars in immersive virtual reality (IVR). For the first time, the viewing of each area of interest of the face in IVR is studied by gender and age. This work in healthy people is conducted to assess the future usefulness of IVR in patients with deficits in the recognition of facial expressions. Seventy-four healthy volunteers participated in the study. The materials used were a laptop computer, a game controller, and a head-mounted display. Dynamic virtual faces randomly representing the six basic emotions plus neutral expression were used as stimuli. After the virtual human represented an emotion, a response panel was displayed with the seven possible options. Besides storing the hits and misses, the software program internally divided the faces into different areas of interest (AOIs) and recorded how long participants looked at each AOI. As regards the overall accuracy of the participants' responses, hits decreased from the youngest to the middle-aged and older adults. Also, all three groups spent the highest percentage of time looking at the eyes, but younger adults had the highest percentage. It is also noteworthy that attention to the face compared to the background decreased with age. Moreover, the hits between women and men were remarkably similar and, in fact, there were no statistically significant differences between them. In general, men paid more attention to the eyes than women, but women paid more attention to the forehead and mouth. In contrast to previous work, our study indicates that there are no differences between men and women in facial emotion recognition. Moreover, in line with previous work, the percentage of face viewing time for younger adults is higher than for older adults. However, contrary to earlier studies, older adults look more at the eyes than at the mouth.Consistent with other studies, the eyes are the AOI with the highest percentage of viewing time. For men the most viewed AOI is the eyes for all emotions in both hits and misses. Women look more at the eyes for all emotions, except for joy, fear, and anger on hits. On misses, they look more into the eyes for almost all emotions except surprise and fear.

RESUMEN

Seeing an angry individual in close physical proximity can not only result in a larger retinal representation of that individual and an enhanced resolution of emotional cues, but may also increase motivation for rapid visual processing and action preparation. The present study investigated the effects of stimulus size and emotional expression on the perception of happy, angry, non-expressive, and scrambled faces. We analyzed event-related potentials (ERPs) and behavioral responses of N = 40 participants who performed a naturalness classification task on real and artificially created facial expressions. While the emotion-related effects on accuracy for recognizing authentic expressions were modulated by stimulus size, ERPs showed only additive effects of stimulus size and emotional expression, with no significant interaction with size. This contrasts with previous research on emotional scenes and words. Effects of size were present in all included ERPs, whereas emotional expressions affected the N170, EPN, and LPC, irrespective of size. These results imply that the decoding of emotional valence in faces can occur even for small stimuli. Supra-additive effects in faces may necessitate larger size ranges or dynamic stimuli that increase arousal.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIM: Many authors have suggested that intimate partner violence (IPV) perpetrators present an imbalance between both branches of the autonomous nervous system when coping with acute stress. Concretely, there is a predominance of the sympathetic branches over the parasympathetic ones when recovering from stress. This imbalance can be explained by their tendency toward anger rumination, and more concretely, by their focus on thoughts of revenge during this period. Unfortunately, there is a gap in the scientific literature in terms of using magnetic resonance imaging (MRI) techniques to assess which brain structures would explain this tendency of IPV perpetrators when coping with acute stress. METHOD: The main objective of this study was to assess whether the gray matter volume (GMV) of relevant brain structures, signaled in previous scientific literature, moderates the association between thoughts of revenge and sympathetic activation during the recovery period, based on skin conductance levels (SCL) after being exposed to stress, in a group of IPV perpetrators (n = 58) and non-violent men (n = 61). RESULTS: This study highlighted that the GMV of the left nucleus accumbens, right lobules of the cerebellum, and inferior temporal gyrus in IPV perpetrators moderated the association between thoughts of revenge and SCL during the recovery period. Accordingly, the higher the thoughts of revenge, the higher the sympathetic predominance (or higher SCL levels), especially among IPV perpetrators with the lowest GMV of these brain structures. Nonetheless, those variables were unrelated in the control group. CONCLUSIONS: Our study highlights the involvement of certain brain structures and how they explain the tendency of some IPV perpetrators to ruminate anger or, more precisely, to focus on thoughts of revenge when they recover from acute stress. These results reinforce the need to incorporate neuroimaging techniques during screening processes to properly understand how IPV perpetrators deal with stress, which in turn helps target their needs and design concrete intervention modules.

RESUMEN

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).

RESUMEN

Ethnic out-group members are disproportionately more often the victim of misidentifications. The so-called other-race effect (ORE), the tendency to better remember faces of individuals belonging to one's own ethnic in-group than faces belonging to an ethnic out-group, has been identified as one causal ingredient in such tragic incidents. Investigating an important aspect for the ORE-that is, emotional expression-the seminal study by Ackerman and colleagues (2006) found that White participants remembered neutral White faces better than neutral Black faces, but crucially, Black angry faces were better remembered than White angry faces (i.e., a reversed ORE). In the current study, we sought to replicate this study and directly tackle the potential causes for different results with later work. Three hundred ninety-six adult White U.S. citizens completed our study in which we manipulated the kind of employed stimuli (as in the original study vs. more standardized ones) whether participants knew of the recognition task already at the encoding phase. Additionally, participants were asked about the unusualness of the presented faces. We were able to replicate results from the Ackerman et al. (2006) study with the original stimuli but not with more standardized stimuli.

RESUMEN

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.

RESUMEN

The ability to detect and recognize facial emotions emerges in childhood and is important for understanding social cues, but we know relatively little about how individual differences in temperament may influence early emotional face processing. We used a sample of 419 children (Mage = 10.57 years, SD = 1.75; 48% female; 77% White) to examine the relation between temperamental shyness and early stages of emotional face processing (assessed using the P100 and N170 event-related potentials) during different facial expressions (neutral, anger, fear, and happy). We found that higher temperamental shyness was related to greater P100 activation to faces expressing anger and fear relative to neutral faces. Further, lower temperamental shyness was related to greater N170 activation to faces expressing anger and fear relative to neutral faces. There were no relations between temperamental shyness and neural activation to happy faces relative to neutral faces for P100 or N170, suggesting specificity to faces signaling threat. We discuss findings in the context of understanding the early processing of facial emotional display of threat among shy children.

RESUMEN

Major functions of the olfactory system include guiding ingestion and avoidance of environmental hazards. People with anosmia report reliance on others, for example to check the edibility of food, as their primary coping strategy. Facial expressions are a major source of non-verbal social information that can be used to guide approach and avoidance behaviour. Thus, it is of interest to explore whether a life-long absence of the sense of smell heightens sensitivity to others' facial emotions, particularly those depicting threat. In the present, online study 28 people with congenital anosmia (mean age 43.46) and 24 people reporting no olfactory dysfunction (mean age 42.75) completed a facial emotion recognition task whereby emotionally neutral faces (6 different identities) morphed, over 40 stages, to express one of 5 basic emotions: anger, disgust, fear, happiness, or sadness. Results showed that, while the groups did not differ in their ability to identify the final, full-strength emotional expressions, nor in the accuracy of their first response, the congenital anosmia group successfully identified the emotions at significantly lower intensity (i.e. an earlier stage of the morph) than the control group. Exploratory analysis showed this main effect was primarily driven by an advantage in detecting anger and disgust. These findings indicate the absence of a functioning sense of smell during development leads to compensatory changes in visual, social cognition. Future work should explore the neural and behavioural basis for this advantage.

RESUMEN

AIM: Anger expression is associated with an increased risk of cardiovascular disease. This positive association was confined to individuals with lower perceived social support and outdoor recreational activity. However, the effects of retirement status remain unclear. This study aimed to investigate whether retirement status after the age of 60 years modifies the association between anger expression and the risk of cardiovascular disease in the Japanese population. METHODS: This longitudinal study included 499 community-dwelling retired and employed workers aged 60-79 years, who completed a cardiovascular risk survey in 1997. A Cox proportional hazards model was used to estimate the hazard ratios and 95% confidence intervals of incident cardiovascular disease (ischemic heart disease and stroke) according to anger expression in retired and employed workers after adjusting for potential cardiovascular risk factors. RESULTS: A total of 37 participants experienced incident cardiovascular disease during the mean follow-up period of 14.8 years (standard deviation 5.5 years). In retired workers, anger expression was associated with an increased cardiovascular disease risk, whereas no such association was observed in employed workers. The respective hazard ratio per one-standard deviation increment of total anger expression was 1.77 (95% confidence interval 1.29-2.43) and 1.03 (95% confidence interval 0.64-1.66; P for interaction = 0.036) among retired and employed workers, respectively. CONCLUSIONS: A positive association between anger expression and the risk of cardiovascular disease was confined to retired workers, suggesting that continuing work after retirement age could reduce anger expression-related cardiovascular disease risk.
