This study investigated the joint effects of parasympathetic and sympathetic nervous system reactivity to social and non-social stressors on proactive (i.e., goal-directed, unemotional) and reactive (i.e., emotional, impulsive) functions of relational aggression. Two hundred and forty-seven (Mage=18.77years) participants completed a series of stressor tasks while their sympathetic arousal (i.e., skin conductance) and parasympathetic arousal (i.e., respiratory sinus arrhythmia) were assessed. Participants also provided self-reports of their aggressive behavior...

Impulsive aggression is common amongst military personnel after deployment, and may arise because of impaired top-down regulation of the amgydala by prefrontal regions. This study sought to further explore this hypothesis via resting-state functional connectivity analyses in impulsively aggressive combat veterans. Male combat veterans with (n = 28) and without (n = 30) impulsive aggression problems underwent resting-state fMRI. Functional connectivity analyses were conducted with the following seed-regions: basolateral amygdala (BLA), centromedial amygdala (CeM), anterior cingulate cortex (ACC), and anterior insular cortex (AIC)...

In this article the formation of psychopathological predictors auto-aggressive behavior in patients with a first psychotic episode were identified, which became "targets" in the framework of a comprehensive emergency suicide assistance to conduct the crisis psychotherapy. The work was done on the basis of the Sumy regional psychoneurologic dispensary, where 100 patients with a first psychotic episode were examined: 52 of them (core group) had suicidal symptoms and 48 (control group) had not. According to the test results of severity of auto-aggressive predictors (pre-suicidal syndrome) to clinicopsychopathological predictors of auto-aggressive behavior include: the narrowing of the cognitive function (p≤0,001), the avoidance of interpersonal contact (r≤0,001), the presence of affective (p≤0,001) and vegetative (p≤0,01) violations, the autoaggression of moderate severity (p≤0,001) and impulsivity (p≤0,001)...

BACKGROUND: Evaluation of broad-spectrum micronutrient (vitamins and minerals) treatment for childhood ADHD has been limited to open-label studies that highlight beneficial effects across many aspects of psychological functioning. METHOD: This is the first fully blinded randomized controlled trial of medication-free children (n = 93) with ADHD (7-12 years) assigned to either micronutrients (n = 47) or placebo (n = 46) in a 1:1 ratio, for 10 weeks. All children received standardized ADHD assessments...

Irritability and nonviolent aggression are common behavioral features across the population, yet there is limited neurobiological research into subclinical phenotypes representing the lower edge of a symptom continuum ranging from slight irritability to criminal violence. We studied brain structural correlates of irritability in a large healthy cohort to test the hypothesis of associations with fronto-limbic brain structures implicated in mood regulation. In a large multicenter effort, we recruited 409 mentally healthy adults from the community, who received T1-weighted high-resolution 3 T MRI scans...

Research has shown that ostracism results in aggressive behavior towards the ostracising other, but also causes displaced aggression-aggression directed towards an innocent person. Our study investigated whether displaced aggressive responses to ostracism were increased by three types of aggression proneness (readiness for aggression) based on different mechanisms: emotional-impulsive, habitual-cognitive or personality-immanent. Participants (n = 118) played a Cyberball game in which they were either excluded or included, next prepared a hot sauce sample for another person as an indicator of aggression and completed the Readiness for Interpersonal Aggression Inventory...

Although problems with emotion regulation (ER) have long been associated with internalizing symptoms, only recently has an ER framework been applied to the study of aggression. Therefore, little is known about the unique and independent associations between specific domains of the ER construct and different kinds of aggressive tendencies. We sought to explore these associations in two independent samples of young adults. Furthermore, we tested whether gender moderated the proposed emotion dysregulation-aggression link...

This short report presents preliminary data on the role of emotional intelligence (EI) in moderating the relationship between psychopathy and aggression in a nonforensic sample. A sample of 109 volunteer men was administered the Psychopathic Personality Inventory-Revised (PPI-R), the Reactive-Proactive Aggression Questionnaire, and the Mayer-Salovey-Caruso emotional intelligence Test in individual sessions. Correlation and moderation analyzes showed that, at low levels of EI (in terms of strategic ability to understand and manage one's own and others' emotions), people scoring high on the total PPI-R and impulsivity dimension seemed to be both reactively and proactively aggressive...

The Point Subtraction Aggression Paradigm (PSAP) measures aggressive behavior in response to provocations. The aim of the study was to implement the PSAP in a functional neuroimaging environment (fMRI) and evaluate aggression-related brain reactivity including response to provocations and associations with aggression within the paradigm. Twenty healthy participants completed two 12-min PSAP sessions within the scanner. We evaluated brain responses to aggressive behavior (removing points from an opponent), provocations (point subtractions by the opponent), and winning points...

OBJECTIVE: Melatonin, a hormone released preferentially by the pineal gland during the night, affects circadian rhythms and aging processes. As animal studies have shown that melatonin increases resident-intruder aggression, this study aimed to investigate the impact of melatonin treatment on human aggression. METHODS: In a double-blind, randomized, placebo-controlled between-participant design, 63 healthy male volunteers completed the Taylor Aggression Paradigm (TAP) after oral administration of melatonin or placebo...

BACKGROUND: This study tested a moderated-mediation model whereby dimensions of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) differentially predict perpetration of physical intimate partner aggression (IPA) through problematic drinking in intoxicated and nonintoxicated heavy drinkers. METHODS: Participants were 249 heavy drinkers (148 men and 101 women) with a recent history of psychological and/or physical IPA perpetration toward their current partner recruited from 2 metropolitan U...

OBJECTIVES: The association between schizophrenia and violence represents an important issue in psychiatry. Often highly publicized, violent acts raise the question of their detection, prevention, management and treatment. There is no single, direct and exclusive link between aggressiveness and the underlying psychiatric disorder. On the contrary, the processes underlying this violence are multiple and interlinked. In addition to static and dynamic risk factors, cognitive deficits play an important role in the genesis and maintenance of violent and aggressive behavior...

To compare the outcomes among war veterans who pray/do not pray and who were not suffering mental disorders after the Bosnia-Herzegovina war (1992-95). The sample consists of 100 healthy Bosnian war veterans divided in two equal groups-one, a highly religious group inside which were individuals who perform five obligatory prayers every day, and another group of individuals who do not practice any daily prayer. We used Minnesota Multiphase Personal Inventory (MMPI), Profile Index of Emotions (PIE) and Life Style Questionnaire (LSQ)...

The UPPS-P seems to be a promising instrument for measuring different domains of impulsivity in forensic psychiatric patients. Validation studies of the instrument however, have been conducted only in student groups. In this validation study, three groups completed the Dutch UPPS-P: healthy student ( N = 94) and community ( N = 134) samples and a forensic psychiatric sample ( N = 73). The five-factor structure reported previously could only be substantiated in a confirmatory factor analysis over the combined groups but not in the subsamples...

Serotonin has a well-established role in emotional processing and is a key neurotransmitter in impulsive aggression, presumably by facilitating response inhibition and regulating subcortical reactivity to aversive stimuli. In this study 44 men, of whom 19 were violent offenders and 25 were non-offender controls, completed an emotional Go/NoGo task requiring inhibition of prepotent motor responses to emotional facial expressions. We also measured cerebral serotonin 1B receptor (5-HT1BR) binding with [(11)C]AZ10419369 positron emission tomography within regions of the frontal cortex...

OBJECTIVES: A growing empirical literature indicates that emotion-related impulsivity (compared to impulsivity that is unrelated to emotion) is particularly relevant for understanding a broad range of psychopathologies. Recent work, however, has differentiated two forms of emotion-related impulsivity: A factor termed Pervasive Influence of Feelings captures tendencies for emotions (mostly negative emotions) to quickly shape thoughts, and a factor termed Feelings Trigger Action captures tendencies for positive and negative emotions to quickly and reflexively shape behaviour and speech...

Serotonergic mechanisms mediate the expression of personality traits (such as impulsivity, aggression and anxiety) that are linked to vulnerability to psychological illnesses, and modulate the identification of emotional expressions in the face as well as learning about broader classes of appetitive and aversive signals. Faces with neutral expressions signal a variety of socially relevant information, such that inferences about the big five personality traits, including Neuroticism, Extraversion and Agreeableness, can be accurately made on the basis of emotionally neutral facial photographs...

OBJECTIVE: Borderline personality disorder (BPD) is associated with elevated risk for a variety of risky behaviors, including criminal behaviors. Yet, limited research has examined the relation of BPD to criminal justice (CJ) involvement, or the mechanisms underlying this relation. PROCEDURES: This study examined the role of two mechanisms, emotion-driven difficulties controlling impulsive behaviors and physical aggression, in the relation between BPD symptom severity and CJ involvement among 118 patients in residential substance abuse treatment (76% male; 62% African-American)...

BACKGROUND: Risky driving is a common cause of traffic accidents and injuries. However, there is no clear evidence of how difficulties in emotion regulation contribute to risky driving behavior, particularly in small post-Soviet countries. The present study aimed to investigate the relationship between difficulties in emotion regulation and self-reported risky driving behavior in a sample of Lithuanian drivers. METHODS: A total of 246 nonprofessional Lithuanian drivers participated in a cross-sectional survey...

Conduct disorder (CD) is a developmental disorder defined by a repetitive and persistent display of antisocial and aggressive behaviors that violates the rights of others or basic social rules. Recently, resting-state functional magnetic resonance imaging (rsfMRI) has been widely adopted to investigate the altered intrinsic neural activities and the disrupted endogenous brain connectivity of CD. In this study, functional connectivity density (FCD) mapping, a newly developed ultrafast voxel-wise method based on rsfMRI, was applied for the first time to examine the changes in the brain functional connectivity in CD at the voxel level...
