Reactive and proactive aggression is a dichotomous classification of aggression in adults and children. This distinction has been supported by a number of variable-based and factor analytic studies. Due to high inter-correlations, however, the reactive-proactive aggression distinction may not be entirely useful for understanding how group or individual aggressive behavior varies in children and adolescents. Drawing on a sample of primary school-aged children (N = 242) aged 7-12 years, this study sought to determine whether reactive and proactive aggression could be distinguished at the variable-level and the person-level in children...

BACKGROUND: Although impulsive aggression (IA) and dysfunctional response inhibition (RI) are hallmarks of attention-deficit/hyperactivity disorder (ADHD) and disrupted behavioral disorders (DBDs), little is known about their shared and distinct deviant neural mechanisms. AIMS AND METHODS: Here, we selectively reviewed s/fMRI ADHD and DBD studies to identify disorder-specific and shared IA and RI aberrant neural mechanisms. RESULTS: In ADHD, deviant prefrontal and cingulate functional activity was associated with increased IA...

BACKGROUND: Difficulty in controlling emotional impulses is a crucial component of borderline personality disorder (BPD) that often leads to destructive, impulsive behaviours against others. In line with recent findings in aggressive individuals, deficits in prefrontal amygdala coupling during emotional action control may account for these symptoms. METHODS: To study the neurobiological correlates of altered emotional action control in individuals with BPD, we asked medication-free, anger-prone, female patients with BPD and age- and intelligence-matched healthy women to take part in an approach-avoidance task while lying in an MRI scanner...

The enzyme steroid 5α-reductase 2 (5αR2) catalyzes the conversion of testosterone into the potent androgen 5α-dihydrotestosterone. Previous investigations showed that 5αR2 is expressed in key brain areas for emotional and socio-affective reactivity, yet the role of this enzyme in behavioral regulation remains mostly unknown. Here, we profiled the behavioral characteristics of 5αR2 heterozygous (HZ) and knockout (KO) mice, as compared with their wild-type (WT) littermates. While male 5αR2 KO mice displayed no overt alterations in motoric, sensory, information-processing and anxiety-related behaviors, they exhibited deficits in neurobehavioral correlates of dominance (including aggression against intruders, mating, and tube dominance) as well as novelty-seeking and risk-taking responses...

One of the core symptoms of borderline personality disorder (BPD) is emotion dysregulation, which comprises emotion sensitivity, heightened and labile negative affect, deficient appropriate regulation strategies, and a surplus of maladaptive regulation strategies. Although earlier studies provided some evidence for threat hypersensitivity in terms of a negatively biased perception of other people ("negativity bias") and deficits in the recognition of full-blown anger, i.e., higher error rates and slower reaction times, researchers have only recently started studying effects of interindividual differences (e...

Perpetrators of intimate partner violence (IPV) represent a heterogeneous group who engage in a variety of aggressive acts which often co-occur. However, few studies take this co-occurrence into consideration. Failure to consider overlapping forms of IPV confounds understanding of risk factors for physical IPV, which in turn undermines identification, prevention, and intervention efforts. Though rarely studied in emerging adults, personality variables have recently been identified as important correlates of IPV...

We compared long-term growth patterns in teachers' and mothers' ratings of Overt Aggression, Covert Aggression, Oppositional Defiance, Impulsivity/inattention, and Emotion Dysregulation across developmental periods spanning kindergarten through grade 8 (ages 5 to 13 years). We also determined whether salient background characteristics and measures of child temperament and parenting risk differentially predicted growth in discrete categories of child externalizing symptoms across development. Participants were 549 kindergarten-age children (51% male; 83% European American; 17% African American) whose problem behaviors were rated by teachers and parents each successive year of development through 8th grade...

Traditionally, the study of personality disorders had been based on psychoanalytic or behavioral models. Over the past two decades, there has been an emerging neuroscience model of borderline personality disorder (BPD) grounded in the concept of BPD as a condition in which dysfunctional neural circuits underlie its pathological dimensions, some of which include emotion dysregulation (broadly encompassing affective instability, negative affectivity, and hyperarousal), abnormal interpersonal functioning, and impulsive aggression...

Type A and B monoamine oxidases (MAO-A, -B) mediate and modulate intracellular signal pathways for survival or death of neuronal cells. MAO-A is associated with development of neuronal architecture, synaptic activity, and onset of psychiatric disorders, including depression, and antisocial aggressive impulsive behaviors. MAO-B produces hydrogen peroxide and plays a vital role in neuronal loss of neurodegenerative disorders, such as Parkinson's and Alzheimer's diseases. This review presents a novel role of MAO-A and B, their substrates and inhibitors, and hydrogen peroxide in brain function and neuronal survival and death...

Child-to-parent violence is a form of family violence that is still a well-kept secret. Abused parents can be victims of different types of abuse. Children can use both physical and psychological violence such as financial threats to take control of the home. In this situation, parents often no longer dare to contradict their children by fear of triggering uncontrollable violence. Although the phenomenon recently drew the attention of the media, there is still little knowledge about its prevalence and clinical characteristics...

Schizophrenia is associated with an elevated risk of aggression. Cognitive deficits have been associated with inpatient aggression and future violence. The relationship between cognitive deficits and violent behavior has however been inconsistent across studies. In addition, studies have failed to inform how cognitive deficits may contribute to aggression in schizophrenia. The current study examined the association of cognitive deficits with schizophrenia-related aggression and violent offending. It also explored the putative mediating role of negative emotionality on the impact of cognitive deficits on aggression...

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 among military personnel after deployment and may arise because of impaired top-down regulation of the amygdala 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 functional magnetic resonance imaging. Functional connectivity analyses were conducted with the following seed-regions: basolateral amygdala (BLA), centromedial amygdala, 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...
