Reactive and proactive aggression as meaningful distinctions at the variable and person level in primary school‐aged children

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. Exploratory Factor Analysis of data from an aggression instrument measuring both functions and forms of aggression, found a two‐factor construct of aggression constituted by a reactive and proactive aggression factor. A person‐based analysis was then conducted after classifying children according to the presence of reactive and/or proactive aggression. Discriminant function analysis was used to discern whether classifications on the basis of aggression function produced meaningful distinctions in terms of antisocial traits and emotional valence and intensity measures. Two functions were identified which distinguished children with different combinations of reactive and proactive aggression. Reactive‐only aggressive children were defined primarily by high levels of impulsivity, while proactive‐only children were defined primarily by higher levels of antisocial traits. Children high in both types of aggression exhibited both the presence of antisocial traits and impulsivity. Contrary to recent findings, this suggests that differences in aggression functions remain meaningful at the person level in children. Implications for interventions are discussed.

     

Autonomic functioning in reactive versus proactive aggression: The influential role of inconsistent parenting

Research has consistently supported autonomic nervous system (ANS) functioning as a predictor of aggressive behavior in youth. Several studies have further examined how the functioning of the sympathetic (SNS) and parasympathetic (PNS) branches of the ANS interact with environmental factors to predict behavioral outcomes. One factor that has yet to be studied in this context however, is parenting practices. Given that many interventions for externalizing behavior target parenting practices, such as increasing consistent discipline, it may be particularly important to assess whether parenting practices interact with SNS and PNS functioning in the child to influence risk for aggressive behavior. Therefore, the current study addressed this question by examining inconsistent discipline as a moderator of the relationship between baseline SNS versus PNS activity and reactive versus proactive aggression. Data were collected from a sample of fourth graders identified as at‐risk for aggression (N = 188). Results indicated that baseline SNS activity was positively related to proactive aggression under high levels of inconsistent discipline, but negatively related to proactive aggression under very low levels of inconsistent discipline. Baseline PNS activity was negatively associated with reactive aggression under low levels of inconsistent discipline. No main effects were found for SNS or PNS functioning and either form of aggression, emphasizing the importance of taking a biosocial approach to examining the predictors of aggressive behavior in at‐risk youth. Results from this study help to better understand the circumstances under which children are most likely to exhibit reactive versus proactive aggression, better informing targeted prevention and treatment.

     

Insulin secretion during the glucose tolerance test among habitually violent and impulsive offenders

Male habitually violent and impulsive offenders were studied by means of the glucose tolerance tests (GTTs) and insulin measurements. Both in intermittent explosive disorder and in violent antisocial personality, there was a tendency for there to be reactive hypoglycemia. There was a more rapid decline of glucose from hyperglycemia and more rapid return from hypoglycemia to the original basal values in intermittent explosive disorder than in violent antisocial personality. Consistent with this, the enhanced insulin secretion started rapidly but lasted a short time in intermittent explosive disorder.     

The Dynamics of Personality Approach (DPA): 20 Tenets for Uncovering the Causal Mechanisms of Personality

Over the last few decades, most personality psychology research has been focused on assessing personality via scores on a few broad traits and investigating how these scores predict various behaviours and outcomes. This approach does not seek to explain the causal mechanisms underlying human personality and thus falls short of explaining the proximal sources of traits as well as the variation of individuals' behaviour over time and across situations. On the basis of the commonalities shared by influential process-oriented personality theories and models, we describe a general dynamics of personality approach (DPA). The DPA relies heavily on theoretical principles applicable to complex adaptive systems that self-regulate via feedback mechanisms, and it parses the sources of personality in terms of various psychological functions relevant in different phases of self-regulation. Thus, we consider personality to be rooted in individual differences in various cognitive, emotional–motivational, and volitional functions, as well as their causal interactions. In this article, we lay out 20 tenets for the DPA that may serve as a guideline for integrative research in personality science. © 2020 The Authors.

Bidirectional associations between affective empathy and proactive and reactive aggression

Preliminary evidence indicates that affective empathy is differentially related to proactive and reactive functions of aggression. However, additional longitudinal research is needed to understand the potential reciprocal nature of these links. The current study examined the bidirectional associations between affective empathy and proactive and reactive aggression over a 6-month period during middle childhood, with attention to potential gender differences. Data were collected from 294 elementary school children (52% girls; M = 9.25 years; SD = 0.944 years) and their homeroom teachers. Affective empathy was assessed using self-reports, and teachers provided ratings of children's functions of aggression. Data were collected during the fall and spring of one academic year. Overall, results suggest some evidence that affective empathy and functions of aggression are reciprocally linked over time. As predicted, Time 1 empathy was inversely associated with Time 2 proactive aggression and Time 1 reactive aggression was inversely associated with Time 2 empathy. Contrary to expectations, Time 1 proactive aggression was marginally positively associated with Time 2 empathy, and Time 1 empathy was not significantly associated with Time 2 reactive aggression. These prospective links did not differ according to gender. Implications and directions for future research are discussed.     

The longitudinal relationship between angry rumination and reactive–proactive aggression and the moderation effect of consideration of future consequences-immediate

The idea that influential factors for two subtypes of aggression (reactive and proactive aggression) should be different is popular, but the common influential factors have not been examined. Such an examination could help understand the influential factors of aggression from the perspective of multiple motivations affecting the development of aggressive motivations over time. The present study argued that angry rumination would be a common influential factor for both reactive and proactive aggression. In addition, consideration of future consequences (CFC) may moderate the longitudinal effect of angry rumination on proactive aggression. Two studies were conducted to test these hypotheses. In Study 1, a cross-lagged analysis with a 6-month interval was employed. A total of 505 undergraduate students (46% males) completed the questionnaires twice. Results indicated that after a 6-month period, angry rumination predicted reactive aggression but not proactive aggression. Furthermore, reactive aggression predicted angry rumination over time. In Study 2, a moderation analysis was performed with another 437 participants (130 males). The results partly supported our hypotheses, indicating that CFC-immediate (CFC-I) moderated the longitudinal effect of angry rumination on proactive aggression. The present results extended prior research regarding the predictors of proactive and reactive aggression and may contribute to a greater understanding of the development of aggressive motivation. In addition, our research suggested that high CFC-I may be an important factor for the motivation change from reactive aggression to proactive aggression.     

Aggression and bullying

Models are presented describing how bullying others and being bullied are related to proactive and reactive aggressiveness. This was investigated among 1801 pupils in Norwegian schools at the end of grade five and among 2083 pupils at the end of grade eight. Pupils in the two samples were approximately 11 and 14 years old, respectively. The procedure of structural equation modeling with latent variables was followed using LISREL 8.30 to estimate the parameters. Analyses were conducted for boys and girls separately at fifth and eighth grades. Support for the assumptions of factor solution and factorial invariance of the concepts across gender and age was obtained independently from estimating structural parameters. Both proactive and reactive aggressiveness were related to bullying others and to being bullied at Level 5. Among the older pupils, there was a strong relationship between proactive aggressiveness and bullying others, while reactive aggressiveness was much more weakly related to bullying others. Being bullied, on the other hand, was only weakly related to proactive and reactive aggressiveness among the older pupils. Age was therefore an important factor in determining how proactive and reactive aggressiveness were related to bullying. When pupil gender is concerned, power‐related proactive aggressiveness in predicting bullying was a more important factor for boys, while affiliation‐related proactive aggressiveness was a more powerful factor for girls.

敌意归因偏向对反应性攻击的预测及报复动机的中介作用

敌意归因偏向指将模糊情境中他人的行为意图进行敌意归因的倾向,其被认为是导致攻击的主要认知因素,但还缺乏其与反应性、主动性攻击的纵向关系的考察,而且其影响反应性攻击的动力机制也不清楚。本研究通过两个子研究来分别回应这两个问题。研究1的纵向调查结果显示,敌意归因偏向只纵向预测反应性攻击,而不能跨时间地预测主动性攻击。研究2对另一批大学生的横断面调查发现,报复动机可以中介敌意归因偏向与反应性攻击的关系。研究结果提示,敌意归因偏向很可能主要是在反应性攻击的形成中起到重要作用,而对主动性攻击的影响不大,报复动机则很可能是这种作用背后的动力机制之一。     

State anxiety impairs attentional control when other sources of control are minimal

Research suggests anxiety impairs attentional control; however, this effect has been unreliable. We argue that anxiety’s impairment of attentional control is subtle, and can be obscured by other non-emotional sources of control. We demonstrate this by examining conflict adaptation, an enhancement in attentional control following a trial with high conflict between distracter and target stimuli. Participants completed a Stroop task featuring incongruent (e.g. RED in green font; high-conflict) and control (e.g. +++ in green font; low-conflict) trials. More state-anxious participants showed greater Stroop interference following control trials, but interference was uniformly low following incongruent trials. This suggests state anxiety can impair attention, but other sources of top-down control – such as conflict adaptation – can easily overcome this impairment. This is consistent with recent theories of anxious cognition and shows that anxiety researchers must attend to the dynamics and sources of attentional control.
