Does counting to ten increase or decrease aggression? The role of state self-control (ego-depletion) and consequences

Analyzing the effects of physical activity levels on aggressive behavior in college students using a chain-mediated model

This study aims to examine the mediating role of self-efficacy (SE) and self-control (SC) in the relationship between physical activity (PA) and aggressive behaviors (AB) among college students. It provides a basis for the prevention and control of AB among college students. This study employed a survey research methodology, including the PA Level Scale, the General Self-efficacy Scale, the Self-control Scale, and the Chinese Aggressive Behaviors Scale on 950 college students. The chain mediating effect test and Bootstrap analysis were applied. The results were as follows: (1) There was a main effect of PA on SE, SC, and AB as well as all sub-indicators (physical aggression, verbal aggression, anger, hostility, self-directed aggression), i.e., PA had a direct effect on the control of all three; (2) PA level was significantly negatively correlated with AB and significantly positively correlated with SE and SC. That is, the higher the level of PA, the better the SE and SC, and the lower the probability of AB; (3) The three pathways had mediating effects: PA → SE → AB, PA → SC → AB, PA → SE → SC → AB, with effect sizes of 8.78%, 28.63%, and 19.08%, respectively. It is concluded that regular PA is a potent method for decreasing aggressive behavior and psychological issues in university students while additionally promoting self-efficacy and self-control. Increasing the intensity of PA may enhance the effectiveness of these chain benefits.

How it ends: A review of behavioral and psychological phenomena, physiological processes and neural circuits in the termination of aggression in other animals and anger in people

More is known about aggression initiation and persistence in other animals, and anger in people, than about their cessation. This review summarizes knowledge of relevant factors in aggression, mostly in vertebrates, and anger termination in people. The latency, probability and intensity of offensive aggression in mice is controlled by activity in a neuronal subpopulation in ventromedial hypothalamus [VMH]. This activity instantiates an aggressive state termed angriffsbereitschaft ["attack-readiness"]. Fighting in many species is broken into bouts with interbout breaks due to fatigue and/or signals from dorsal raphe to VMH. Eventually, losers decide durations and outcomes of fighting by transitioning to submission or flight. Factors reducing angriffsbereitschaft and triggering these defeat behaviors could include metabolic costs, e.g., lactate accumulation and glucose depletion detected by the hypothalamus, central fatigue perhaps sensed by the Salience Network [insula and anterior cingulate gyrus] and pain of injuries, the latter insufficiently blunted by opioid and non-opioid stress analgesia and transduced by anterior VMH neurons. Winners' angriffsbereitschaft continue for awhile, as indicated by post-victory attacks and, perhaps, triumph displays of some species, including humans. In longer term situations, sensory and/or response habituation of aggression may explain the "Dear enemy" tolerance of competitive neighbors. Prolonged satiation of predatory behavior could involve habenula-regulated reduction of dopaminergic reward in nucleus accumbens. Termination of human anger involves at least three processes, metaphorically termed decay, quenching and catharsis. Hypothesized neural mechanisms include anger diminution by negative feedback from accumbens to anterior cingulate and/or activity in the Salience Network that controls anger's "accumulation/offset" phase.

Relationships Among Normative Beliefs About Aggression, Moral Disengagement, Self-Control and Bullying in Adolescents: A Moderated Mediation Model

Purpose

Adolescent bullying has varying degrees of negative impact on both bullies and victims. Bullying in adolescents is complex, and the influence of individual factors and social factors should not be underestimated. Normative beliefs about aggression play an important role in adolescents’ bullying. However, the mediating and moderating mechanisms underlying this association remain largely unknown. The current study investigated the mediating role of moral disengagement between normative beliefs about aggression and bullying, as well as the moderating role of self-control in this relationship from the perspective of individual cognition.

Methods

A sample of 491 Chinese adolescents (female = 38.9%; mean age = 13.05 years) were study participants. They completed questionnaires about normative beliefs about aggression, bullying, moral disengagement and self-control. SPSS21.0 statistical software was used to collate the obtained data, analyze descriptive statistics, and carry out reliability analysis and correlation analysis.

Results

Moral disengagement mediated the relationship between normative beliefs about aggression and bullying (ab=0.13, 95% CI=[0.07, 0.21]). The association between normative beliefs about aggression and moral disengagement was moderated by self-control (β=−0.08, t=−2.25, p<0.05). The association between moral disengagement and bullying was moderated by self-control (β=−0.09, t=−2.42, p<0.05).

Conclusion

Results revealed that moral disengagement mediates the link between normative beliefs about aggression and bullying. Self-control moderated the relationship between normative beliefs about aggression and moral disengagement, and between moral disengagement and bullying.

Does state self-control depletion predict relationship functioning and partner aggression? An ecological momentary assessment study of community couples

Intimate relationship functioning depends upon the ability to accommodate one's partner and to inhibit retaliatory and aggressive impulses when disagreements arise. However, accommodation and inhibition may be difficult when self-control strength is weak or depleted by prior exertion of self-control. The present study considered whether state self-control depletion prospectively predicts male and female self-reports of anger with partner and arguing with partner. Consistent with the I³ Model (Finkel, 2014, Adv Exp Soc Psychol, 49, 1-104), we also considered whether the association between elevated anger and arguing (i.e., instigation) and partner aggression was stronger when state self-control (i.e., inhibition) was depleted or among people high in negative urgency. In this ecological momentary assessment (EMA) study, heavy drinking married and cohabiting heterosexual couples (N = 191) responded to three randomly signaled reports each day for 30 days. Depletion predicted anger and arguing with partners both cross-sectionally and prospectively for men and women. However, after controlling for prior levels of anger and arguing, these effects were diminished, and supplemental analyses revealed that anger and arguing with partner predicted subsequent depletion. Anger and arguing were strongly associated with concurrent reports of partner aggression perpetration and victimization (verbal and/or physical). However, neither state self-control depletion nor negative urgency moderated these effects. Overall, results suggest a modest impact of depletion on daily couple functioning as well as a potential cyclical effect of arguing on depletion.

The Relationship Between Self-Efficacy and Aggressive Behavior in Boxers: The Mediating Role of Self-Control

Aggressive behavior has been one of the core issues in sports psychology, whereas boxers' aggressive behavior has received limited attention. Although some literature reported that self-efficacy is related to aggressive behavior, the mechanism whereby self-efficacy affects aggressive behavior remains unclear. The present study investigated the relationship between self-efficacy and aggressive behavior, as well as the effect of self-control as a mediating factor. This study uses the Self-efficacy Scale for Athletes, the Self-control Questionnaire for Athletes, and the Buss-Perry Aggression Questionnaire. This relationship is explored through self-reported measures from N = 414 Chinese professional boxers, n = 243 were male and n = 171 were female, the average age was M = 17.72 years (SD = 3.147), the participants, the average number of years of exercise was M = 3.89 years (SD = 2.734); Results showed that male boxers reported greater aggression than female boxers; It was found that the self-efficacy and self-control improved as age of the participants increased; The higher the level of competition, the higher levels of self-efficacy and self-control; Self-efficacy was negatively related with aggressive behavior and positively correlated with self-control. Self-control was also negatively correlated with aggressive behavior among boxers. Self-control had a full mediating effect on the relationship between self-efficacy and aggressive behavior.
