The development of bystander intentions and social–moral reasoning about intergroup verbal aggression

A developmental intergroup approach was taken to examine the development of prosocial bystander intentions among children and adolescents. Participants as bystanders (N = 260) aged 8–10 and 13–15 years were presented with scenarios of direct aggression between individuals from different social groups (i.e., intergroup verbal aggression). These situations involved either an ingroup aggressor and an outgroup victim or an outgroup aggressor and an ingroup victim. This study focussed on the role of intergroup factors (group membership, ingroup identification, group norms, and social–moral reasoning) in the development of prosocial bystander intentions. Findings showed that prosocial bystander intentions declined with age. This effect was partially mediated by the ingroup norm to intervene and perceived severity of the verbal aggression. However, a moderated mediation analysis showed that only when the victim was an ingroup member and the aggressor an outgroup member did participants become more likely with age to report prosocial bystander intentions due to increased ingroup identification. Results also showed that younger children focussed on moral concerns and adolescents focussed more on psychological concerns when reasoning about their bystander intention. These novel findings help explain the developmental decline in prosocial bystander intentions from middle childhood into early adolescence when observing direct intergroup aggression.     

FUNCTIONAL ANALYSIS AND TREATMENT OF ESCAPE-MAINTAINED AGGRESSION CORRELATED WITH SLEEP DEPRIVATION

Functional analysis identified the consequences that maintained aggressive behavior and the relationship between those consequences and sleep deprivation for an individual with severe mental retardation. Results showed that aggression was maintained by negative reinforcement contingencies (escape from demand) and that aggression was more severe when sleep deprivation was present. A multicomponent intervention resulted in reductions of aggression for up to 7 months.     

A comparison of human aggression committed by groups and individuals: An interindividual-intergroup discontinuity

Experimental research comparing aggressive behavior committed by groups and individuals is important but sparse. This experiment compared aggressive behavior (i.e., amount of hot sauce allocated for others to consume) in four types of interactions: intergroup, interindividual, group-to-individual, and individual-to-group. The results revealed that intergroup interactions were significantly more aggressive than interindividual interactions. In addition, groups allocated and received significantly more hot sauce than individuals. These effects were not explained by diffusion of responsibility or trait aggressiveness. The experiment reveals two noteworthy conclusions: (1) the interindividual-intergroup discontinuity effect extends to aggressive behavior and (2) interactions in which a group is either the source or target of aggression are situational influences that can increase it.     

Rumination and the Displacement of Aggression in United Kingdom Gang‐Affiliated Youth

The concept of gang aggression oftentimes elicits images of brutal intergang violence. In reality, gang‐related aggression can vary widely, can have various motivations and causal factors, and includes interpersonal as well as intergroup aggression. This study examined the tendency of UK youth to engage in displaced aggression (aggression aimed at undeserving targets) and examined the relationship among gang affiliation, ruminative thought, and aggression levels. Students in three London schools were asked to complete a questionnaire that assessed levels of gang affiliation, rumination about aversive events, and a tendency to engage in displaced aggression. Our analyses found a three‐way interaction between gang affiliation, rumination, and gender, such that males who were high in affiliation and rumination had the greatest tendency to displace aggression toward innocent others. Additionally, it was shown that rumination could account for a significant part of the correlation between gang affiliation and displaced aggression. Furthermore, regression analyses showed that even after controlling for trait aggression, anger, hostility, and irritability, rumination remained a significant predictor of displaced aggression. The implications for understanding gang‐related aggression and for conducting future research in this area were discussed. Aggr. Behav. 38:89‐97, 2012. © 2011 Wiley Periodicals, Inc.

Reciprocal influences between maternal discipline techniques and aggression in children and adolescents

Most studies assessing the link between parental discipline and child aggression have focused primarily on discipline as a cause and aggression as an outcome. In addition to the pathway from discipline to aggression, however, aggressive behavior on the part of the child may lead to future use of discipline by the parent. In this study, structural equation modeling was used to assess reciprocal influences over time between a mothers' use of discipline and aggression in children. Data were drawn from the Springfield Child Development Project, a longitudinal study of middle childhood and adolescence, focusing on antecedents of aggression. The original sample consisted of 440 mother-child dyads living in the city of Springfield, MA. Children in the sample were between 7 and 14 years of age at the first data collection period and between 12 and 19 years of age at the final data collection period. Four hypotheses were tested: (1) a mother's use of aggressive discipline predicts an increase in later child aggression, (2) child aggression predicts an increase in later use of aggressive discipline, (3) the use of reasoning predicts a decrease in later child aggression, and (4) child aggression predicts an increase in later use of reasoning. All hypotheses except number 3 were supported to some degree. Results suggest that children's early aggressive behavior leads to an increase in their mothers' use of both reasoning and aggressive discipline; in turn, increased use of aggressive discipline leads to an increase in aggression during both childhood and adolescence.     

AGGRESSION AS POSITIVE REINFORCEMENT IN MICE UNDER VARIOUS RATIO‐ AND TIME‐BASED REINFORCEMENT SCHEDULES

There is evidence suggesting aggression may be a positive reinforcer in many species. However, only a few studies have examined the characteristics of aggression as a positive reinforcer in mice. Four types of reinforcement schedules were examined in the current experiment using male Swiss CFW albino mice in a resident—intruder model of aggression as a positive reinforcer. A nose poke response on an operant conditioning panel was reinforced under fixed‐ratio (FR 8), fixed‐interval (FI 5‐min), progressive ratio (PR 2), or differential reinforcement of low rate behavior reinforcement schedules (DRL 40‐s and DRL 80‐s). In the FR conditions, nose pokes were maintained by aggression and extinguished when the aggression contingency was removed. There were long postreinforcement pauses followed by bursts of responses with short interresponse times (IRTs). In the FI conditions, nose pokes were maintained by aggression, occurred more frequently as the interval elapsed, and extinguished when the contingency was removed. In the PR conditions, nose pokes were maintained by aggression, postreinforcement pauses increased as the ratio requirement increased, and responding was extinguished when the aggression contingency was removed. In the DRL conditions, the nose poke rate decreased, while the proportional distributions of IRTs and postreinforcement pauses shifted toward longer durations as the DRL interval increased. However, most responses occurred before the minimum IRT interval elapsed, suggesting weak temporal control of behavior. Overall, the findings suggest aggression can be a positive reinforcer for nose poke responses in mice on ratio‐ and time‐based reinforcement schedules.     

Children’s social cognition about proactive aggression

In this study, 6- and 9-year-old children (N = 258) observed two instances of proactive aggression (one relational and the other direct aggression) that were committed by members of a group toward out-group members. Participants were either members of the group or independent observers. Analyses of participants’ social cognition about the aggressor and the aggression (cause of aggression, moral judgment of aggression, attitudes toward the aggressor, and exclusion of the aggressor) indicated that, overall, group members were more positive toward aggressors than were independent observers. Although intergroup competition was perceived to be the cause of the aggression, participants disapproved of both types of aggression (especially direct aggression), disapproval increased with age, and girls disapproved of relational aggression more than did boys. Group members’ social cognition about the aggressor and the aggression comprised a coherent cognitive process for both types of aggression, but the observers’ process was simpler and differed by aggression type.     

Group membership,group norms,empathy, and young children's intentions to aggress

This study assessed the effect of ingroup norms and empathy on 6 and 9‐year‐old children's (N=161) attitudes and aggressive intentions toward outgroup members. Prior to an intergroup drawing competition against an outgroup, participants' empathy was measured, and they were randomly assigned to a simulated group with a norm of direct or indirect aggression, or no aggression norm. Results indicated participants' attitudes were less positive toward the outgroup vs. the ingroup, and that both direct and indirect aggressive intentions were displayed toward the outgroup. Most importantly, the ingroup was liked less when it had an aggression norm, and the participants' aggressive intentions were not enhanced by the group aggression norm. Empathy was a significant negative predictor of direct but not indirect aggression intentions. Implications for understanding the instigation and inhibition of children's aggression intentions are discussed. Aggr. Behav. 35:244–258, 2009. © 2009 Wiley‐Liss, Inc.     

Evaluation of aggressive interactions in interpersonal and intergroup contexts

The article deals with possible differences in the evaluation of interpersonal and intergroup aggression. Study I investigated whether the typical perspective-specific divergence in judgments about aggressive interactions (with actors evaluating their behavior as more reasonable and less inappropriate than recipients) varied in interpersonal and intergroup contexts. Additionalty, the possible mediating influence of lay epistemic motivation and subjective judgmental confidence was explored. Results indicated that the social context had an important impact on the evaluation of aggressive interactions: there was a lower dissent between actors and recipients in the intergroup than in the interpersonal condition. However, the direction of this pattern of data differed from what could be derived from theories of aggressive and intergroup behavior. Subjective confidence and lay epistemic motivation did not influence the inappropriatencess ratings. Study II tried to shed some further light on the context-specific evaluation of aggressive interaction by presenting episodes of different severity and by obtaining judgments on both actions as well as reactions. Results showed that-irrespective of severity-aggressive reactions were evaluated more negatively in intergroup contexts. It is proposed that this effect stemmed from context-specific differences in the application of the norm of reciprocity.
