Aggression in dyadic interaction

It is shown that the notions of aggressive behavior as ‘intentional emission of noxious stimulation’ (Buss, 1961, 1963, 1966, 1971) and that of ‘injuriating goal response’ (Dollard, Doob, Miller, Mower and Sears, 1939) are identical. The usefulness of these theories to predict S's reaction to the reception of a given noxious stimulation is questioned. It is suggested that S's reactions to noxious stimulation may or may not be aggressive, depending on whether the noxious stimulation S receives is interpreted as being a behavior justified by the nom in the situation, or as reflecting an aggressive intent of O. It is hypothesized that the norms established in the situation depend on (i) victim's perception of the noxious stimulation received as being instrumental for O's goal attainment, (ii) victim's perception of the value of O's goal, and (iii) the value of victim's own goal. The establishment of norms regulating the exchange of noxious stimulation between Ss is operationalized in two experiments. Aggression, defined as an infringement of these norms, is measured. In Experiment I, participate 56 female students, and in Experiment 2, 80 male students. Subject is alternately victim (he performs a sensorimotor task and receives an electric shock) and aggressor (he shocks the other S). In Experiment I it is found that Ss counteraggress faster and more frequently if they interpret the shock received from the partner as an infringement of the norm. In Experiment 2, Ss do not counteraggress more frequently, but they do counteraggress faster and evaluate O more negatively. It is concluded that the results clearly contradict current positions and favor the authors' cognitive reformulation of the determinants of aggressive behavior.     

Influence of contextual information on observers' perceptions of actors' intentions to harm others

Previous examinations of perceptions of aggressive behaviors have used static stimulus presentations (e.g., photographs or slides). This investigation examined the impact of varying amounts of geographical and temporal contextual information on observers' perceptions of actors' intentions to physically and psychologically (intimidate) harm others. Participants (51 elite ice hockey players) were randomly assigned to view one of three video-taped presentations showing eight ice hockey behaviors in either a) a dynamic mode with contextual information, b) a dynamic mode with no context, or c) a static, “freeze-frame” mode. MANOVA results showed that non-aggressive stimuli were perceived as less aggressive, and aggressive stimuli were perceived as more aggressive in dynamic presentations with context than in static presentations. Based on these findings, it is suggested that future research focussing on perceptions of aggressive behavior utilize a dynamic stimulus presentation containing context material. © 1996 Wiley-Liss, Inc.     

Proactive and reactive aggression in early adolescence as precursors to anti- and prosocial behavior in young adults

Three groups of adolescents who were 14 years old in 1974 were formed on the basis of peer nominations and teacher ratings in an ongoing longitudinal study: 1) reactively aggressive (REA) individuals who displayed reactive, that is, self-defensive aggression but not proactive aggression (43 boys, 35 girls); 2) proactively aggressive (PROA) individuals who attacked another person without a reason (56 boys, 35 girls); and 3) nonaggressive (NONA) individuals who were low in proactive and reactive aggression (48 boys, 45 girls). The groups were compared at ages 8, 14, and 27 in variables representing the constructs of a two-dimensional model of emotional and behavioral regulation. The REA Ss were characterized by higher self-control, especially constructiveness, at each age and better adult adjustment than the PROA Ss. The PROA males were prone to externalizing problems and criminality in adulthood, whereas the PROA females were prone to internalizing problems and neuroticism in adulthood. Both exhibited conduct problems in adolescence, and became heavy users of alcohol in adulthood. The PROA Ss had more children at age 27 than the other Ss. © 1996 Wiley-Liss, Inc.     

Exposure to maternal vs. paternal partner violence,PTSD, and aggression in adolescent girls and boys

Adolescents who witness interparental violence (IPV) are at increased risk for perpetrating aggressive acts. They are also at risk for post‐traumatic stress disorder (PTSD). In this study, we examined the relation between exposure to maternal vs. paternal physical IPV and adolescent girls' and boys' aggressive behavior toward mothers, fathers, friends, and romantic partners. We also assessed the influence of PTSD (as assessed by the Diagnostic Interview for Children and Adolescents‐IV (DICA‐IV)) on the relation between exposure to IPV and aggressive behavior. Participants were 63 girls and 49 boys, ages 13–18, consecutively admitted to a youth correctional facility or assessment facility designated to serve aggressive and delinquent youth. Structural equation modeling was used to estimate unique relations between exposure to maternal vs. paternal IPV and youth aggression in relationships. Girls who observed their mothers' aggressive behavior toward partners were significantly more aggressive toward friends. Similarly, boys who witnessed their fathers' aggression were significantly more aggressive toward friends. Adolescent girls and boys who observed aggression by mothers toward partners reported significantly higher levels of aggression toward their romantic partners. Approximately one third of our sample met PTSD criteria; the relation between exposure to parental IPV and aggression was stronger for individuals who met criteria for PTSD. The implications of understanding the relations between parents' and their daughters' and sons' use of aggression are discussed within the context of providing support for families in breaking intergenerational patterns of violence and aggression.

Temporal Orientation,Human Movement Responses and Time Estimation

The relationship between temporal orientation, human movement (M) responses on the Barron inkblots, and brief time estimates was investigated. Knapp's Time Metaphor Test and the Barron inkblots were administered to 110 Ss. 40 Ss were selected on the basis of their scores on the Time Metaphor Test to participate in an individual time estimation experiment This produced two criterion groups: 20 Dynamic-Hasty (D-H) Ss and 20 Naturalist-Passive (N-P) Ss. Results indicated that N-P Ss had a lower M threshold, perceived more M and overestimated the passage of time. Discussion focused on the relationship between temporal orientation, fantasy behavior, and impulse control.     

Stimulus complexity,free looking time,and inspective exploration

Fourteen Ss rated 59 objects on a seven point complexity scale. From these ratings 10 objects were chosen at the high, middle, and low levels of complexity, and 35 mm slides were made of these 30 objects. Fifteen Ss manipulated and inspected each of the objects for as long as they wished and a second group of 15 Ss viewed slides of the objects for as long as they wished. Analysis of the time scores from these two groups revealed that both inspective manipulation time and free looking time increased as a function of stimulus complexity. Inspective manipulation time was greater than free looking time except at the low complexity level.     

Defending victims of cyberbullying: The role of self-efficacy and moral disengagement

Cyberbullying is a significant problem worldwide that affects adolescents' social relations, academic achievement, and mental health. As this form of bullying is typically viewed by a large audience it is important to understand the role of observers as they may hold a key for reducing bullying. The aim of this study was to investigate the role of the socio-cognitive factors of defending self-efficacy (i.e., belief in one's capability to defend) and moral disengagement (i.e., justifications for aggressive behavior) associated with general cyber defending behavior and cyber defending response types: constructive and aggressive. Participants were 540 male and female students of diverse racial identity between the ages of 11 and 15 years who completed a questionnaire comprising multiple measures. Regression analyses revealed that at low levels of defending self-efficacy, moral disengagement was unrelated to general cyber defending behavior. However, at high levels of defending self-efficacy, moral disengagement was positively associated with general cyber defending. Further regression analyses revealed that the results for constructive cyber defending were the inverse of those obtained for aggressive defending. Defending self-efficacy was positively associated with constructive defending and negatively associated with aggressive defending. Moral disengagement was negatively associated with constructive defending and positively associated with aggressive defending. These results address the perplexing issue of why moral disengagement has been related to defending in some studies and not in others. As with most measures of defending, the general cyber defending measure confounds constructive and aggressive defending.     

Aggression is associated with greater subsequent alcohol consumption: A shared neural basis in the ventral striatum

Alcohol use and abuse (e.g., binge drinking) are among the most reliable causes of aggressive behavior. Conversely, people with aggressive dispositions (e.g., intermittent explosive disorder) are at greater risk for subsequent substance abuse. Yet it remains unknown why aggression might promote subsequent alcohol use. Both aggressive acts and alcohol use are rewarding and linked to greater activity in neural reward circuitry. Through this shared instantiation of reward, aggression may then increase subsequent alcohol consumption. Supporting this mechanistic hypothesis, participants’ aggressive behavior directed at someone who had recently rejected them, was associated with more subsequent beer consumption on an ad‐lib drinking task. Using functional MRI, both aggressive behavior and beer consumption were associated with greater activity in the bilateral ventral striatum during acts of retaliatory aggression. These results imply that aggression is linked to subsequent alcohol abuse, and that a mechanism underlying this effect is likely to be the activation of the brain's reward circuitry during aggressive acts.

     

Flies on the wall are less aggressive: Self-distancing “in the heat of the moment” reduces aggressive thoughts,angry feelings and aggressive behavior

People tend to ruminate after being provoked, which is like using gasoline to put out a fire—it feeds the flame by keeping aggressive thoughts and angry feelings active. In contrast, reflecting over past provocations from a self-distanced or “fly on the wall” perspective reduces aggressive thoughts and angry feelings. However, it is unclear whether people can self-distance “in the heat of the moment” (i.e., immediately after being provoked), and if they can, whether doing so reduces actual aggressive behavior. Two experiments addressed these issues. The results indicated that provoked participants who self-distanced had fewer aggressive thoughts and angry feelings (Experiment 1) and displayed less aggressive behavior (Experiment 2) than participants who self-immersed or were in a control group. These findings demonstrate that people can self-distance in the heat of the moment, and that doing so reduces aggressive thoughts, angry feelings, and aggressive behavior.     

Ego depletion and aggressive behavior: Is the inhibition of aggression a limited resource?

If self‐regulation is a limited resource, the capacity to inhibit aggressive behavior should be lower among people who have already exercised self‐regulation. In Experiment 1, participants who had to resist the urge to eat tempting food later reacted more aggressively to an insult than other participants who were allowed to eat as much as they wanted. In Experiments 2 and 3, some participants had to self‐regulate by making themselves concentrate on a boring film and stifling their physical and facial movements, and afterward they, too, responded more aggressively than controls. Experiment 3 also showed that the results were not due to differential moods and that one act of self‐regulation (unrelated to aggression) was sufficient to enhance subsequent aggressive responses toward the experimenter.

The Conditional Reasoning Measurement System for Aggression: An Overview

The Conditional Reasoning Measurement System is described. This procedure focuses on how people solve what on the surface appear to be inductive reasoning problems. The true intent of the problems is to determine if solutions based on implicit biases are logically attractive to a respondent. In this article, we focus on the types of implicit biases that underlie aggressive individuals' attempts to justify aggressive behavior. People who consistently select solutions based on these types of biases are scored as being potentially aggressive because they are cognitively prepared to rationalize aggression. Scores on the Conditional Reasoning Test for Aggression (CRT-A) have been shown to have acceptable psychometric properties and an average, uncorrected validity of .44 against behavorial criteria (in 10 studies).     

Rape Myth Acceptance in College Students: How Far Have We Come?

Researchers have emphasized the significant roleof rape myth acceptance in individuals' predispositionto engage in sexually aggressive behavior, includingrape. The purpose of this study was to examine the current state of rape myth acceptance incollege students and the factors which differentiatedacceptance vs nonacceptance of rape myths. One hundredfifty-eightprimarily Caucasian respondents were provided with two measures of attitudes towardrape and asked the degree to which they agreed ordisagreed with each statement. Results indicated thatcollege students reported disagreement with rape myth statements. However, variations in the degreeof disagreement emerged; men and individuals who had notattended a rape awareness workshop expressed weakerdisagreement with rape myths than women and individuals who had attended a rape awareness workshop.Discriminant analysis of these variables successfullyidentified a core set of rape myths which differentiatedindividuals in terms of the degree to which they subscribed to rape-supportive attitudes.Conclusions were drawn regarding rape myth acceptanceand the need for further research.     

Men's memory for women's sexual‐interest and rejection cues

The current work characterizes young men's memory for young women's heterosocially relevant affective cues (e.g. sexual interest and rejection) and examines characteristics of both the woman being perceived and the male perceiver as predictors of memory. Undergraduate men (n = 232) completed similarity‐ratings and recognition‐memory tasks with photos of undergraduate women who varied in attractiveness, provocativeness of clothing and expression of sexual interest. Participants also completed a control memory task and a measure relevant to the risk of exhibiting sexually aggressive behaviour, as well as indicating how many serious relationships they had experienced. Multilevel regression techniques revealed that (a) men's memory for women's sexual interest improved when women were sexually interested at encoding, attractive and dressed provocatively; (b) men who reported more frequent serious relationships showed better memory for women's sexual interest and (c) men at risk of exhibiting sexually aggressive behaviour showed worse memory for women's sexual interest.

Decentration as a means for reducing aggression after exposure to violent stimuli

Studied the effects of decentration as a self-control process to reduce the aggression subsequent to exposure to filmed violence. 48 Belgian French-speaking military recruits were run in four groups of subjects. Two saw either aggressive or neutral slides without special instructions. The other two groups saw only aggressive slides but one underwent the decentration training while the fourth one performed a subsidiary task instead. The famous ‘weapons effect’ is replicated for those subjects who did not receive the special instructions (<.025 one-tailed test) and decentration significantly reduces aggression (<.05 one-tailed test). The absence of a change in the meaning of the slides is interpreted in terms of reappraisal of the stimuli. Besides practical questions, theoretical implications are raised concerning the social context of viewing filmed violence.     

Judgment stability and pseudorecognition of random and patterned configurations

Thirty six simple patterns were judged as “random” or “patterned” by adult Ss. Category judgments were consistent whether Ss were told that 1/4, 1/2, or 3/4 of the patterns were random or if no proportion was specified. In a second experiment, Ss viewed a series of slides previously judged patterned followed by a recognition series with two additional patterned slides inserted in a series of otherwise random slides. Although slides were never labeled random or patterned, Ss made the most false recognitions for the two patterned slides. In another condition where random and patterned slides were reversed, most false recognitions were made for the two random slides. Both Gamer’s notion of hypothetical set size and an analysis of balanced elements fit the results, but the adequacy of both hypotheses can be questioned when applied to previous results with more complex patterns.     

Pain thresholds,pain-induced frontal alpha activity and pain-related evoked potentials are associated with antisocial behavior and aggressiveness in athletes

ObjectivesDeficiencies in perceptual and cognitive functions have been linked with antisocial and aggressive behavior. To test whether these putative relationships generalize to sport – a context where such behavior is common – we determined the extent to which pain thresholds and cortical activity in response to painful electrical stimulation were associated with antisocial and aggressive behavior in sport; we also examined their link to moral disengagement.DesignA cross-sectional design was used.MethodNinety-four participants completed questionnaires, had their pain threshold determined, and then had their central and frontal pain-related cortical activity recorded while they were electrically stimulated at supra-threshold intensity.ResultsSubjective pain thresholds were positively related while pain induced frontal alpha power was negatively related to antisocial behavior and aggressiveness. Central pain evoked potential amplitudes were negatively related to aggressiveness and moral disengagement.ConclusionsSensitivity to and cortical processing of noxious stimuli were reduced in individuals who more frequently behave antisocially and aggressively when playing sport and who are more likely to use psychosocial maneuvers to justify their harmful behavior. Our findings reveal that pain-related deficits are a feature of individuals who engage in more frequent antisocial and aggressive behavior in the context of sport.     

Mothers' responses to infant physical appearance

Mothers' responses to slides of infants were assessed. During individual presentations of the slides they showed increases in smiling to infant photographs in general, but showed large skin conductance responses only to pictures of their own infant. They did not look differentially at the photographs. During paired presentations, mothers looked longer at their own infant's photograph. Moreover, they looked longer at unfamiliar infants who they perceived to be high in cuteness. These findings are discussed with reference to the role of infant physical appearance in infant-adult social relations.     

Threats,Promises, and Coalitions: A Study of Compliance and Retaliation in a Simulated Organizational Setting1

This research sought to examine the effects of threats and promises on compliance and the formation of subordinate coalitions in a simulated employeremployee conflict situation. It also sought to determine some of the motives underlying coalition decisions-tangible and intangible-and the conditions under which each of these possible motive types would be salient. Coalition motives were examined by manipulating the consequences for coalition members following their use of coalition power (presence vs. absence of monetary gain). A control condition was present in which no such power was available. Ninety male undergraduate business students were randomly assigned to one of six experimental conditions in a 3 × 2 factorial design. Three Ss engaged in a modified bilateral monopoly bargaining task in which two of them (the “employees”) believed they were exchanging a series of offers and counteroffers with the third (the “employer”) over a hypothetical wage increase for a maximum of eight rounds. Ss were told they would earn a sum of money proportional to the effectiveness of their bargaining. In actuality, all Ss were assigned the employee role and all employer “offers” were pre-programmed. On round six, the Ss were “sent” either a threat or promise message by the employer demanding that they accept his round five offer. Compliance-noncompliance was defined as employee acceptance-rejection of this demand, respectively. In addition to compliance behavior, S s in coalition conditions had the power to form an alliance with the other employee against the employer after the latter used his threat or promise power. Coalitions could confiscate up to 25% of the employer's earnings and, depending on experimental condition, could either keep or not keep any money their coalition acquired. It was hypothesized that threateners would elicit less compliance, and be responded to with more, and more severe subordinate coalitions than would promisers. It was further assumed that there would be less compliance when subordinates had coalition power, and that the effect of monetary reward on the likelihood of coalition formation would be contingent on the type of power (threats vs. promises) the employer used. Specifically, it was assumed that a majority of S s in the Threat condition who had this power would form coalitions against the employer regardless of whether or not they realized any tangible gain for doing so. In the promise condition, however, it was expected that coalition decisions would be based primarily on whether Ss stood to gain monetarily. The hypotheses were supported. These results were discussed in terms of the impact of power acquisition as a variable mediating perception and compliance behavior, and in terms of the role of economic vs. retaliatory motives as factors underlying subordinate coalition decisions. Some of the conditions which influence the relative salience of these two coalition motives were proposed, and the organizational implications of these findings were suggested.     

Aggression levels in college students after exposure or non-exposure to an aggressive life experience

Through a secondary analysis of existing data, the authors researched the question of what types of aggressive behaviors are learned from an individual's social environment. The findings included data on three student groups: 1) students who had never been in military service; 2) students who had been in military service and had been to Viet Nam; and 3) students who had been in military service, but who had not been to Viet Nam. The results indicated that assault is clearly one aggressive behavior that appears to increase with exposure to an aggressive life experience.     

Punitiveness in response to films varying in content: A cross-national field study of aggression

Punitiveness in male movie-goers in London, Philadelphia, Rome and Toronto was measured before or after they attended films varying in content (aggressive, sexual, neutral) and arousal potential (low, high). A second dependent variable, altruism, was also assessed for some Ss. Hypotheses stemming from social learning theory and arousal theory were tested by comparing changes in punitiveness at aggressive, nonaggressive arousing (sexual) and nonaggressive nonarousing (neutral) films. At aggressive films there was an increase in punitiveness whereas a reduction in punitiveness was found at neutral films. Sexual films led to a smaller (nonsignificant) increase in punitiveness than aggressive films. The findings implied that arousal was a necessary, but not sufficient, condition for increasing punitiveness. There were no significant cross-national differences in response to the films. Since the results did not generalize to other, nonaggressive responses, the film effects may be aggression-specific. Two additional findings in the U.S. sample were that urban Ss were more punitive than rural Ss and that the length of urban residency correlated negatively with altruism.
