Emotion perception in habitual players of action video games.

Emotion 2020 Jul 6. Epub 2020 Jul 6.

Faculty of Psychology and Educational Sciences, University of Geneva, Campus Biotech.

Action video game players (AVGPs) display superior performance in various aspects of cognition, especially in perception and top-down attention. The existing literature has examined these performance almost exclusively with stimuli and tasks devoid of any emotional content. Thus, whether the superior performance documented in the cognitive domain extend to the emotional domain remains unknown. Read More

Self-Persuasion: An Experimental Evaluation of a Sexual Aggression Preventive Intervention for U.S. College Men.

J Interpers Violence 2020 Jul 4:886260520936369. Epub 2020 Jul 4.

Indiana University Bloomington, USA.

Grounded in the self-persuasion paradigm (an indirect persuasion approach, which places people in situations that motivate them to change their behavior), this study evaluated a brief, online intervention to reduce sexual aggression perpetration and increase prosocial bystander behaviors among heterosexual male college students ( = 241) in the United States. Students were randomly assigned to three conditions: (a) a self-persuasion intervention, (b) a social norms control condition, and (c) a control condition focusing on sense of belongingness. The self-persuasion intervention integrated three social psychological theoretical perspectives on attitudinal and behavioral change-cognitive dissonance (e. Read More

Whose fault is it? Attribution of causes of patient violence among exposed and unexposed community-based family physicians.

Health Soc Care Community 2020 Jul 6. Epub 2020 Jul 6.

Maccabi Health Care Services, Tel-Aviv, Israel.

Extensive research has dealt with violence directed at healthcare workers in hospital settings; however, few studies have examined community-based settings. Furthermore, there is also scant literature regarding the perceptions of healthcare providers who were exposed to violence, compared to those who were not. This study aims to narrow these gaps in the literature by examining community-based family physicians' (CBFPs) perceptions in a large national Health Maintenance Organisation (HMO) regarding patient-initiated violence.

The effects of callous-unemotional traits and aggression subtypes on amygdala activity in response to negative faces.

Psychol Med 2020 Jul 6:1-9. Epub 2020 Jul 6.

Department of Child and Adolescent Psychiatry and Psychotherapy, Central Institute of Mental Health, Medical Faculty Mannheim/Heidelberg University, Mannheim, Germany.

Background: Brain imaging studies have shown altered amygdala activity during emotion processing in children and adolescents with oppositional defiant disorder (ODD) and conduct disorder (CD) compared to typically developing children and adolescents (TD). Here we aimed to assess whether aggression-related subtypes (reactive and proactive aggression) and callous-unemotional (CU) traits predicted variation in amygdala activity and skin conductance (SC) response during emotion processing.

Methods: We included 177 participants (n = 108 cases with disruptive behaviour and/or ODD/CD and n = 69 TD), aged 8-18 years, across nine sites in Europe, as part of the EU Aggressotype and MATRICS projects. Read More

Examining the Role of Genetic Risk and Longitudinal Transmission Processes Underlying Maternal Parenting and Psychopathology and Children's ADHD Symptoms and Aggression: Utilizing the Advantages of a Prospective Adoption Design.

Behav Genet 2020 Jul 4. Epub 2020 Jul 4.

Prevention Science Institute, University of Oregon, Eugene, OR, USA.

Although genetic factors may contribute to initial liability for ADHD onset, there is growing evidence of the potential importance of the rearing environment on the developmental course of ADHD symptomatology. However, associations between family-level variables (maternal hostility, maternal depressive symptoms) and child behaviors (developmental course of ADHD and aggression) may be explained by genes that are shared by biologically related parents and children. Furthermore, ADHD symptoms and aggression commonly co-occur: it is important to consider both simultaneously to have a better understanding of processes underlying the developmental course of ADHD and aggression.

Effect of previous fighting on the dynamic of agonistic encounters in zebrafish males.

Anim Cogn 2020 Jul 2. Epub 2020 Jul 2.

Laboratorio de Neuroendocrinología y Comportamiento, DBBE, IBBEA-CONICET, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, CABA, Intendente Güiraldes 2160, Pabellón 2, Piso 4º, Laboratorio26, C1428EHA, Buenos Aires, Argentina.

Aggression among individuals which compete for resources such as food or territory, or to establish dominance relationships, can cause injuries that may be risky for the contenders. In this way, individuals of many species have strategies to resolve conflicts reducing levels of aggression. Thus, if individuals are able to recognize each other and remember previous agonistic experiences and the result of the fight, they will resolve the subsequent encounter with lower levels of aggression.

Polytomous Item Explanatory Item Response Theory Models.

Educ Psychol Meas 2020 Aug 13;80(4):726-755. Epub 2019 Dec 13.

University of California at Berkeley, Berkeley, CA, USA.

This study investigates polytomous item explanatory item response theory models under the multivariate generalized linear mixed modeling framework, using the linear logistic test model approach. Building on the original ideas of the many-facet Rasch model and the linear partial credit model, a polytomous Rasch model is extended to the item location explanatory many-facet Rasch model and the step difficulty explanatory linear partial credit model. To demonstrate the practical differences between the two polytomous item explanatory approaches, two empirical studies examine how item properties explain and predict the overall item difficulties or the step difficulties each in the Carbon Cycle assessment data and in the Verbal Aggression data.

Qualitative Systematic Review of Emotional Processes and Social Interaction: Behavioral Analysis in Contexts of Political Violence.

Int J Psychol Res (Medellin) 2019 Jul-Dec;12(2):91-104

Laboratory of studies and clinical applications in contexts of political violence, Faculty of Psychology, Fundación Universitaria Konrad Lorenz, Bogotá, Colombia Fundación Universitaria Konrad Lorenz Bogotá Colombia.

Emotional processes and social interactions are relevant units in the study of the actors involved in contexts of political violence, since they have been exposed to constant conflict and they can develop inappropriate behaviors in daily life. Despite the fact that works on the subject are outlined, very few approach the phenomenon from a perspective of behavioral analysis, specially because of the advances that are denoted in related topics. That is why this review seeks to analyze the conceptual and methodological trends in written production on this subject from this theoretical perspective. Read More

Triarchic Model Traits as Predictors of Bullying and Cyberbullying in Adolescence.

J Interpers Violence 2020 Jun 29:886260520934448. Epub 2020 Jun 29.

University of Florence, Italy.

The triarchic model of psychopathy includes a disinhibition dimension related to externalizing outcomes, a meanness dimension pertaining to callous-unemotional traits, and a boldness dimension referring to emotional stability and high confidence in peer relationships. Some dimensions of psychopathy have been extensively investigated in samples of children and adolescents; in particular, the callous-unemotional (meanness) dimension has been associated with aggression and bullying in numerous studies. However, the other dimensions of the triarchic model have been relatively unexplored in samples of adolescents. Read More

Key Laboratory of Biorheological Science and Technology, Ministry of Education, College of Bioengineering, Chongqing University, Chongqing 400030, China.

Cross-talk between tumor cells and mechanical stress in the tumor microenvironment has been shown to be involved in carcinogenesis. High mechanical stress in tumors can alter the metabolism and behaviors of cancer cells and cause cancer cells to attain cancer stem-like cell properties, thus driving tumor progression and promoting metastasis. The mechanical signal is converted into a biochemical signal that activates tumorigenic signaling pathways through mechanotransduction. Read More

In this essay, I show how difficult emotions, like aggression and murderous rage, are grappled with in horror movies. Patients' reactions to viewing these films can take place in a safe, creative, therapeutic space that allows for even the darkest themes. I discuss three patients who related to intense rage at the mother when viewing the films Joker and Jurassic Park. Read More

Sensation seeking, impulsivity, and aggression moderate sex effects on adolescent laboratory binging.

Psychol Addict Behav 2020 Jun 25. Epub 2020 Jun 25.

Department of Psychiatry and Psychotherapy.

Sex, comprising biological and gender-related distinctions, is a known risk factor for alcohol use disorders. Moreover, sensation seeking, impulsivity, and aggression have been found to predict binge drinking and to reflect behavioral disinhibition. We tested effects of these disinhibited traits on binging during intravenous alcohol self-administration (ivASA), a method that eliminates sex differences in the pharmacokinetics of alcohol.

A novel in vivo measure of cyberaggression.

Aggress Behav 2020 Jun 24. Epub 2020 Jun 24.

Department of Advertising and Social Media, Michigan State University, East Lansing, Michigan.

Cyberaggression (CA), or the use of information communication technologies to inflict harm on others, is an emerging public health crisis. Unfortunately, our current ability to assess CA in a research context remains limited, curtailing efforts to address this important issue. We sought to fill this gap in the literature by developing an adapted "chat" version of the Taylor aggression paradigm (TAP) that would more closely resemble a social gaming format (hereafter referred to as the TAP-Chat).

Alcohol, conflict, and aggression in intimate relationships: A dyadic approach.

J Soc Pers Relat 2019 May 2;36(5):1459-1475. Epub 2019 Apr 2.

Rochester Institute of Technology, USA.

Intimate partner aggression (IPA) is a critical public health problem that requires clear and testable etiological models that may translate into effective interventions. While alcohol intoxication and a pattern of heavy alcohol consumption are robust correlates of IPA perpetration, there has been limited research that examines this association from a dyadic perspective. In the present review, we discuss compelling reasons for understanding dyadic factors that assist our understanding of alcohol-facilitated IPA, review the relatively small number of studies that have investigated such factors, and provide a theoretical and methodological framework for researchers to conceptualize how to model alcohol-facilitated IPA from a dyadic framework.
