Higher Levels Of Reactive Aggression Research Articles

The cognitive neural mechanism of response inhibition and error processing to fearful expressions in adolescents with high reactive aggression.

Reactive aggression in adolescents is characterized by high levels of impulsivity. This is associated with deficits in response inhibition and error processing and spontaneous emotion-driven responses to a perceived threat. However, the characteristics and cognitive neural mechanisms of response inhibition and error processing to indirect threat in adolescents with high levels of reactive aggression are unclear. This study explored the characteristics and cognitive neural mechanisms of response inhibition and error processing to fearful expressions in adolescents with high levels of reactive aggression using an emotional Go/No-Go paradigm combined with ERP recordings. Adolescents with high levels of reactive aggression (n = 31) and a control group (n = 30) took part in this study. Results showed that when presented with fearful expressions, adolescents with high levels of reactive aggression showed a smaller No-Go P3 effect and smaller ERN amplitudes following commission errors on the No-Go task than the control group. Results suggested that when presented with fearful expressions, adolescents with high levels of reactive aggression have impaired response inhibition in the later stage of actual inhibitory control of the motor system and impaired error processing in the early stage of fast and automatic initial error detection.

Psychosocial Correlates of Reactive and Proactive Aggression among Protesters during the Social Movement in Hong Kong.

This pioneering study examined how psychosocial factors predicted reactive and proactive aggression among adolescents and young adults in Hong Kong during the Anti-Extradition Bill Movement. A total of 1027 local secondary and tertiary students (578 male, 449 female) aged from 12 to 25 years (M = 16.95, SD = 3.30) completed a questionnaire measuring political participation and attitudes, victimization experiences, aggression, life satisfaction, moral disengagement, and psychopathic traits. ANCOVA and multiple linear regression analyses were performed. The results revealed that compared with non-protesters, protestors had more negative traits and poorer well-being (higher levels of reactive aggression, moral disengagement, narcissism, and impulsivity; lower life satisfaction; more experiences of victimization by strangers related to political disputes). Nonetheless, protesters had similar psychosocial correlates of reactive and proactive aggression when compared to the non-protesters. Among the protesters, reactive aggression was positively predicted by anger towards the government, moral justification, diffusion of responsibility, impulsivity, and narcissism and negatively predicted by satisfaction with the government, advantageous comparison, and dehumanization. Furthermore, proactive aggression was positively predicted by narcissism, euphemistic language, and advantageous comparison and negatively predicted by moral justification. The implications of the findings for psychotherapy, school education, parenting, and social policies are discussed.

Modulation of Amygdala Response by Cognitive Conflict in Adolescents with Conduct Problems and Varying Levels of CU Traits

Adolescents with conduct problems and low callous-unemotional traits are characterised by high levels of reactive aggression. Prior studies suggest that they can have exaggerated neural and behavioural responses to negative emotional stimuli, accompanied by compromised affect regulation and atypical engagement of prefrontal areas during cognitive control. This pattern may in part explain their symptoms. Clarifying how neurocognitive responses to negative emotional stimuli can be modulated in this group has potential translational relevance. We present fMRI data from a cognitive conflict task in which the requirement to visually scan emotional (vs. calm) faces was held constant across low and high levels of cognitive conflict. Participants were 17 adolescent males with conduct problems and low levels of callous-unemotional traits (CP/LCU); 17 adolescents with conduct problems and high levels of callous-unemotional traits (CP/HCU, who typically show blunted reactivity to fear), and 18 typically developing controls (age range 10–16). Control participants showed typical attenuation of amygdala response to fear relative to calm faces under high (relative to low) conflict, replicating previous findings in a healthy adult sample. In contrast, children with CP/LCU showed a reduced (left amygdala) or reversed (right amygdala) attenuation effect under high cognitive conflict conditions. Children with CP/HCU did not differ from controls. Findings suggest atypical modulation of amygdala response as a function of task demands, and raise the possibility that those with CP/LCU are unable to implement typical regulation of amygdala response when cognitive task demands are high.

The long-term effect of media violence exposure on aggression of youngsters

The effect of media violence on aggression has always been a trending issue, and a better understanding of the psychological mechanism of the impact of media violence on youth aggression is an extremely important research topic for preventing the negative impacts of media violence and juvenile delinquency. From the perspective of anger, this study explored the long-term effect of different degrees of media violence exposure on the aggression of youngsters, as well as the role of aggressive emotions. The studies found that individuals with a high degree of media violence exposure (H-MVE) exhibited higher levels of proactive aggression in both irritation situations and higher levels of reactive aggression in low-irritation situations than did participants with a low degree of media violence exposure (L-MVE). After being provoked, the anger of all participants was significantly increased, and the anger and proactive aggression levels of the H-MVE group were significantly higher than those of the L-MVE group. Additionally, rumination and anger played a mediating role in the relationship between media violence exposure and aggression. Overall, this study enriches the theoretical understanding of the long-term effect of media violence exposure on individual aggression. Second, this study deepens our understanding of the relatively new and relevant phenomenon of the mechanism between media violence exposure and individual aggression.

Sleep restriction alters reactive aggressive behavior and its relationship with sex hormones.

Few studies have experimentally manipulated sleep to study its effect on aggressive behavior. The current study examined how reactive aggression was affected by having sleep restricted to 4-hours on a single night, a level of disruption commonly experienced. Both rested and sleep-restricted participants completed the Point Subtraction Aggression Paradigm (PSAP), a laboratory task in which participants seek to earn points, are provoked by a fictitious opponent stealing their points, and may choose to steal points in response. Logistic mixed-effect models were used to investigate the effect of sleep restriction and the role of sex hormones on the odds of choosing to steal. For men, and women in the luteal phase of the menstrual cycle, sleep restriction did not result in significant changes reactive aggression, although the patterns of aggressive behavior appeared less reactive and retaliatory in nature. For women in the follicular phase of the menstrual cycle, sleep restriction was associated with higher levels of reactive aggression. For both men and women in the luteal phase, sleep restriction disrupted an association between hormone change over the task (testosterone and estradiol, respectively) and reactive aggression that was observed in their control participants. In addition, higher testosterone before the PSAP in men was associated with maintaining a high level of stealing over the task. These results indicate a complex dynamic in which sex hormones and sleep interact to predict aggressive behavior in response to provocation.

Theory of Mind Deficits and Reactive Aggression in Child Psychiatric Inpatients: Indirect Effects Through Emotion Dysregulation

Nationwide, there is a pressing need to develop more efficacious treatment regimens for reactively aggressive youth receiving inpatient psychiatric services. Identifying the relevant clinical characteristics of youth with reactive aggression is an important first step in this process. Past research findings and theoretical formulations have suggested that deficits in both social skills and emotional regulation abilities are significantly associated with the development of reactive aggression in children. Utilizing a highly aggressive child inpatient sample (65 males and 36 females) receiving crisis-stabilization services, we tested the hypothesis that emotion dysregulation statistically mediated the relationship between theory of mind deficits and reactive aggression. As hypothesized, results of bootstrapped mediational analyses indicated that theory of mind deficits were associated with higher levels of reactive aggression via the indirect influence of dysregulated affect. These findings suggest that intervention programs for reactively aggressive children should promote both theory of mind skills and emotion regulation abilities. Children that develop more thoughtful styles of perspective taking coupled with an enhanced ability to modulate their emotions may develop a greater ability to employ the rational conflict resolution skills that underlie peaceful social relationships.

The Effects of Child Maltreatment From Parents on Reactive Aggression Among Upper-Elementary-School Students and the Moderating Role of Effortful Control

Objective: This study examined the influences of child maltreatment and effortful control on reactive aggression among upper-elementary-school students and investigated whether children’s effortful control had any moderating effects on the relationship between child maltreatment and reactive aggression. Methods: The participants of this study consisted of 438 students (225 boys and 213 girls) from four elementary schools located in Seoul, Incheon, and the Gyeonggi Province. The level of reactive aggression was assessed via the Peer Conflict Scale (Marsee, Kimonis, & Frick, 2004). The Child Trauma Questionnaire (Bernstein & Fink, 1998) was used to measure the level of child maltreatment from parents. Effortful control was measured by the Early Adolescent Temperament Questionnaire—Revised (Ellis & Rothbart, 2001). The statistical analyses of data for this study included descriptive statistics and hierarchical regressions. The moderating effect of effortful control was analyzed by using the procedures proposed by Baron and Kenny (1986). Results: The results of this study indicate that the level of child maltreatment increases the level of reactive aggression and that the level of effortful control decreases the level of reactive aggression for boys and girls. In addition, effortful control only moderated the influence of maltreatment on reactive aggression for girls. Conclusion: Higher levels of child maltreatment led to lower levels of child effortful control and (subsequently) higher levels of reactive aggression.

Bidirectional Associations between Peer Victimization and Functions of Aggression in Middle Childhood: Further Evaluation across Informants and Academic Years.

The current 3-wave study examined bidirectional associations between peer victimization and functions of aggression across informants over a 1-year period in middle childhood, with attention to potential gender differences. Participants included 198 children (51% girls) in the third and fourth grades and their homeroom teachers. Peer victimization was assessed using both child- and teacher-reports, and teachers provided ratings of reactive and proactive aggression. Cross-classified multilevel cross-lagged models indicated that child-reports, but not teacher-reports, of peer victimization predicted higher levels of reactive aggression within and across academic years. Further, reactive aggression predicted subsequent increases in child- and teacher-reports of peer victimization across each wave of data. Several gender differences, particularly in the crossed paths between proactive aggression and peer victimization, also emerged. Whereas peer victimization was found to partially account for the stability of reactive aggression over time, reactive aggression did not account for the stability of peer victimization. Taken together with previous research, the current findings suggest that child-reports of peer victimization may help identify youth who are risk for exhibiting increased reactive aggression over time. Further, they highlight the need to target reactively aggressive behavior for the prevention of peer victimization in middle childhood.

Reactive/proactive aggression and the development of internalizing problems in males: The moderating effect of parent and peer relationships

The current study examined whether reactive and/or proactive aggression in adolescent males prospectively predicted increased levels of internalizing symptoms (depression and anxiety) in late adolescence. It was postulated that reactive aggression would be robustly related to later internalizing problems, but only among adolescent males who had problematic family or peer social relationships. Participants were a racially diverse group of 289 adolescent males (Mean age = 16). Measures of reactive and proactive aggression, peer rejection, and poor parent-adolescent communication were examined as predictors of both depression and anxiety symptoms assessed approximately 3 years later. The interactive effects between the two facets of aggression and measures of peer rejection and poor parent-adolescent communication in predicting internalizing problems was also examined. Adolescents with high levels of reactive aggression were more likely to exhibit elevated internalizing problems during late adolescence, even when controlling for pre-existing levels of anxiety/depression. However, this association only emerged for adolescents who had high levels of peer rejection and/or poor communication with their parent. Consistent with expectations, proactive aggression was unrelated to internalizing symptoms regardless of social relationship quality. Adolescent reactive, but not proactive, aggression is a risk factor for the development of internalizing problems. However, the findings suggest that interventions designed to foster positive social relationships among reactively aggressive youth may help protect them from developing significant internalizing problems over time.

Social Problems as a Mediator of the Link Between Reactive Aggression and Withdrawn/Depressed Symptoms

The current study examined whether social problems accounted for the relation between reactive aggression and withdrawn/depressed symptoms in a sample of 147 children (54.4% male) ranging from 5 to 13 years of age (M = 8.22 years) who attended a community based after-school program. Findings suggested that indeed social problems mediated the link between reactive aggression and withdrawn/depressed symptoms, such that high levels of reactive aggression are associated with high levels of social problems, which in turn are associated with high levels of withdrawn/depressed symptoms. Findings suggest the need to target peer relationships in the prevention of subsequent negative emotions for children who exhibit high levels of reactive aggression.

Aggression, ADHD symptoms, and dysphoria in children and adolescents diagnosed with bipolar disorder and ADHD

BackgroundThis study had two objectives: (1) examine characteristics of aggression in children and adolescents diagnosed with bipolar disorder and (2) determine whether the CBCL pediatric bipolar disorder profile differentiated youngsters with bipolar disorder from youngsters with ADHD. MethodChildren and adolescents referred to a pediatric psychopharmacology clinic were systematically evaluated for psychopathology using a psychiatrist-administered diagnostic interview, parent- and teacher-report rating scales assessing the child's behavior, and child-completed self-report scales. In this sample, 27 children and adolescents were diagnosed with bipolar disorder and 249 youngsters were diagnosed with ADHD without co-occurring bipolar disorder. These two groups were compared to determine whether there were significant differences on various measures of psychopathology. ResultsYoungsters diagnosed with bipolar disorder were more verbally aggressive and exhibited higher levels of reactive aggression than youngsters with ADHD without co-occurring bipolar disorder. Youngsters with bipolar disorder also reported higher levels of depressive symptoms than youngsters with ADHD without bipolar disorder. The CBCL pediatric bipolar disorder profile did not accurately identify youngsters diagnosed with bipolar disorder. ConclusionsThe present findings present a picture of manic youngsters as verbally aggressive and argumentative, who respond with anger when frustrated. Youngsters diagnosed with bipolar disorder and ADHD exhibited significant levels of impulsive behavior and attention problems, but youngsters with bipolar disorder also exhibited significant levels of aggressive behavior and dysphoric mood. Finally, the CBCL pediatric bipolar disorder profile did not accurately identify youngsters who were diagnosed with bipolar disorder.

Traditional and Cyber Aggressors and Victims: A Comparison of Psychosocial Characteristics

To date, relatively little is known about differences between perpetrators and victims of cyber and traditional forms of aggression. Hence, this study investigated differences among traditional and cyber aggressors and victims on psychosocial characteristics typically examined in research on traditional aggression and victimization, specifically effortful control, manipulativeness, remorselessness, proactive and reactive aggression, and anxious/depressive symptoms. Participants (N = 300; 63.2% female; M age = 12.89, SD = .95; 52% Caucasian, 27% African American, 11% Latino, and 10% other) were categorized based on aggressor type (non/low aggressor, traditional-only, cyber-only, and combined traditional and cyber) and victim type (non-victim, traditional-only, cyber-only, and combined traditional and cyber). Cyber aggressors reported lower levels of reactive aggression compared to traditional-only and combined aggressors. Combined aggressors demonstrated the poorest psychosocial profile compared to all other aggressor groups. For victimization, cyber-only and combined victims reported higher levels of reactive aggression and were more likely to be cyber aggressors themselves compared to traditional-only victims and non-victims. Findings suggest that there may be unique aspects about cyber aggression and victimization that warrant further investigation.

The Relation Between Childhood Proactive and Reactive Aggression and Substance Use Initiation

The current study examined whether proactive and reactive aggression were associated with the risk for initiation of substance use from fourth to ninth grade in a sample of 126 aggressive children (66% male). In addition, the study examined whether these functions of aggression increased risk for initiation via peer delinquency and peer rejection. Proactive aggression was marginally significantly directly associated with risk for initiation of alcohol use and indirectly associated with risk for initiation of marijuana and tobacco use through peer delinquency. Reactive aggression was associated with increased risk for initiation of tobacco and marijuana use through a complex chain that included both peer rejection and peer delinquency. However, high levels of reactive aggression that did not lead to peer rejection were negatively associated with risk for initiation of tobacco and marijuana use. Implications for intervention are discussed.

Pathways from proactive and reactive aggression to substance use.

Childhood aggression is a known risk factor for adolescent substance use; however, aggression is a complex construct, and developmental researchers have identified a variety of subdimensions that may be germane to substance use. Very little research has examined risk pathways from subdimensions of aggression. The current study examined a developmental model and tested whether childhood proactive aggression, reactive aggression, or both were related to the development of substance use in adolescence in a sample of 126 children (mean age at initial assessment = 10.4 years, SD = 0.51). Peer rejection and peer delinquency were examined as potential mediators of these relations. The findings suggest that proactive aggression was indirectly associated with substance use through peer delinquency. Reactive aggression was also indirectly associated with substance use through a complex mediational chain, such that high levels of reactive aggression were associated with high levels of peer rejection, which in turn were associated with peer delinquency (p = .06), which subsequently predicted substance use.

The Relations among Observational, Physiological, and Self‐Report Measures of Children's Anger

AbstractOur first goal was to examine the relations among observational, physiological, and self‐report measures of children's anger. Our second goal was to investigate whether these relations varied by reactive or proactive aggression. Children (272 second‐grade boys and girls) participated in a procedure in which they lost a game and prize to a confederate who cheated. Skin conductance reactivity, heart rate reactivity, self‐reports of anger, angry facial expressions, and angry nonverbal behaviors were measured for each turn of the game. We used multi‐level regressions to calculate the relations among the 10 pairs of the five anger variables over the course of the game. Six of the 10 pairs of anger variables were positively related. These findings suggest that measuring children's anger using any one approach may not capture the full complexity of children's overall experience and expression of anger. Furthermore, three of the 10 relations were stronger at higher levels of reactive aggression, although none varied by proactive aggression. These findings suggest that reactive aggression is related to greater cohesiveness in the experience and expression of anger than is proactive aggression.

Reactive and Proactive Aggression Differentially Predict Later Conduct Problems

This study tested whether proactive and reactive aggression were differently predictive of later externalizing problems such as delinquency and DSM‐related disruptive behaviors (i.e. oppositional defiant and conduct disorders). It also tested whether these two subtypes of aggressive behaviors interacted in predicting externalizing problems. A community sample of low SES boys participated in the study. Proactive and reactive aggression were rated by teachers when boys were 12 years old. Delinquency, oppositional disorders, and conduct disorders were assessed during mid‐adolescence. Proactive but not reactive aggression predicted delinquency and disruptive behaviors. Moreover, high levels of reactive aggression weakened the link between proactive aggression and delinquency. Reactive aggression, however, did not moderate the link between proactive aggression and disruptive behaviors. We conclude that reactive and proactive aggression are two distinct types of aggressive behaviors with different predictive abilities. We also offer tentative explanations to account for the present findings.
