Instigation to aggress and escalation of aggression examined from a personological perspective: The role of irritability and of emotional susceptibility

Two studies were conducted using Buss hostility machine paradigm to investigate the role of individual differences in irritability and emotional susceptibility on the instigation to aggress by a self-esteem lowering manipulation and on the hypothesized escalation of aggression over trials. The role of sex was also examined. In the first study, 60 highly irritable and 60 low irritable subjects were given the opportunity to deliver electric shocks to an experimental confederate, half after being provoked by a negative judgement on their performance in a learning task, half without such an experience. Each group of subjects was divided equally between males and females. It was found that highly irritable subjects, both males and females, delivered higher shocks after provocation than low irritable subjects under similar circumstances. An upward drift of shock level over trials was found only in provoked males and only in highly irritable females. In the second study, 60 highly emotionally susceptible and 60 low emotionally susceptible males and females were given the opportunity to deliver electric shocks to an experimental confederate, half after experiencing provocation, half without such an experience. It was found that provoked subjects delivered higher shocks than unprovoked subjects and that highly emotionally susceptible subjects delivered higher shocks than low emotionally susceptible subjects. Whereas an upward drift of shock levels over trials was found only in provoked males, the same effect was found in females, whether provoked or not. These findings are discussed in terms of the importance of stable personality characteristics that may mediate aggressive response.     

The effects of alcohol and the salience of aggressive cues on triggered displaced aggression

Alcohol increases the aggression-augmenting effects of provocation. Theories of alcohol and aggression suggest that impaired cognitive processing induced by acute intoxication leads individuals to process aggression-inducing social cues differently depending on whether they are high or low in salience. We examined the effects of intoxication and aggressive cue salience within the triggered displaced aggression paradigm. An ethnically diverse sample of 74 primarily young adult participants (40 men and 34 women; M=23.28, SD=3.14 years) were recruited from the university community and surrounding area. All participants were provoked by an experimenter, randomly assigned to a 2 (alcohol condition: alcohol vs. placebo) x 2 (trigger salience: high vs. low salience) between-subjects design, and then given the opportunity to aggress against the undeserving triggering agent. As expected, intoxication combined with a salient triggering cue elicited the most displaced aggression among all conditions. These results provide the first evidence that the effect of alcohol on triggered displaced aggression is moderated by the salience of the triggering event.     

Trait displaced aggression and psychopathy differentially moderate the effects of acute alcohol intoxication and rumination on triggered displaced aggression

When angered, alcohol and rumination increase aggression toward the source of a subsequent minor annoyance. Little is known about individual differences that moderate this phenomenon. One hundred university students (47 men, 53 women) were provoked and given either alcohol or placebo and subsequently induced to ruminate or engage in distraction. Participants were then given the opportunity to aggress against a somewhat annoying fictitious participant by determining the amount of hot sauce the other participant must consume. Alcohol and rumination independently augmented aggressive behavior, and these effects were moderated by trait displaced aggression and psychopathy, respectively. These findings suggest alcohol use and rumination as targets of intervention, specifically for those high in trait displaced aggression and psychopathy.     

Status of the provoker,opportunity to retaliate,and interest in video violence

Two hypotheses derived from affect-dependent stimulus arrangement theory [Zillmann D, Bryant J (1985): In: “Selective Exposure to Communication.” Hillsdale, NJ: Erlbaum Associates.] were tested: (1) provoked persons will express less interest in seeing video violence than will those not provoked, unless they anticipate an opportunity to retaliate against their provocateur; and (2) when provoked persons anticipate an opportunity to retaliate against a provocateur who is not high status, they will express greater interest in seeing video violence than will those not provoked. After being provoked or not provoked by a high or low status experimenter, half the 160 male college student participants were led to believe that their evaluation of the experimenter would determine the experimenter's grade for conducting the research, and half were not given any reason to expect an opportunity to evaluate him. Then each man indicated his degree of interest in seeing each of twelve video selections that had been described in brief paragraphs, three each in four content categories: aggressive, humorous, mildly erotic, and neutral. In confirmation of the first hypothesis, provoked subjects who did not anticipate opportunity to retaliate expressed less interest in seeing aggressive material than did those not provoked. In relationship to the second hypothesis, provoked subjects showed the greatest interest in aggressive video material when they anticipated an opportunity to retaliate against a low status provocateur, but their interest was not greater than corresponding nonangered subjects. The effect of provocation upon interest in the other categories of video material was generally in line with what would be predicted from the theory. When there was no anticipated opportunity to retaliate, interest in humorous material was greater in provoked subjects than in those not provoked. In the case of the mildly erotic category of video selections, there was less interest expressed among provoked subjects when they anticipated having a chance to retaliate against a low status experimenter.     

Attribution and aggression: The misattribution of anger

An experiment was designed to test the effect of misattribution of anger on subsequent aggression. Subjects were induced to take a placebo with half of the subjects led to expect arousal symptoms and the other half led to expect relaxation. Crosscutting the pill manipulation, half of the subjects were provoked by a confederate and half were not. All subjects were then given an opportunity to aggress against the confederate. As predicted, relaxation pill-provoked subjects were significantly more aggressive than subjects in the other conditions (p < .025), with arousal pill-provoked subjects no more aggressive than no provocation controls.     

Aggression and Heat: The Mediating Role of Negative Affect1

Sixty-four undergraduate males received either very postive or very negative personal evaluations from an attitudinally similar or dissimilar stranger, and were then given an opportunity to aggress against this person by means of electric shock. Half were exposed to these stimuli under comfortably cool environmental conditions, while half were so treated under uncomfortably hot conditions. It was predicted that aggression toward the victim would increase as the degree of negative affect induced among subjects by the experimental conditions increased up to moderate levels, but that beyond this point, further increments in negative affect would actually tend to inhibit such behavior. A significant (p < .007) curvilinear relationship between negative affect and aggression supported these predictions, and suggested that such affect mediates the influence of high ambient temperatures on human aggression.     

Olfaction and Human Social Behavior: Effects of Pleasant Scents on Physical Aggression

Forty-eight male undergraduates participated in an experiment designed to investigate the effects of pleasant scents on physical aggression. Subjects were first angered or not angered by a male or female confederate, and then provided with an opportunity to aggress against this person. One third aggressed in the presence of a very pleasant scent (perfume), a second third aggressed in the presence of a mildly pleasant scent (pine-scented aerosol). The remaining subjects aggressed in the absence of any pleasant aroma. Results indicated that when the victim was male, aggression was enhanced by the presence of perfume if subjects had been angered, but reduced by this scent d they had not been provoked, in contrast, when the victim was female, aggression was enhanced by the presence of perfume regardless of whether subjects had previously been angered. The pine-scented aerosol failed to exert any significant effects upon subjects' behavior. These findings were interpreted as consistent with the suggestion that the impact of pleasant scents on social behavior may stem from several different mediating mechanisms, including heightened arousal and shifts in social perception.     

Retaliatory motivation enhances attributions of hostility when people process ambiguous social stimuli

We hypothesized that provocation and readiness to aggress (Retaliatory Motivation) would increase the tendency to construe the ambiguous actions of others as reflecting hostile intent. Male undergraduates were either verbally provoked or not provoked by a male experimenter and half were led to believe that they would be allowed to retaliate anonymously against the provoker in the form of a potentially damaging written evaluation. Participants then rated the hostility and aggressive intent of the characters in brief ambiguous scenarios of interpersonal conflict. According to prediction, men who were provoked and anticipated retaliation against their provoker rated the scenarios as containing hostility and aggression to a significantly greater extent than did non‐provoked or merely provoked participants. Results are discussed within a motivation‐based affective relevance model of perception. Aggr. Behav. 29:155–172, 2003. © 2003 Wiley‐Liss, Inc.     

Lashing Out after Stewing over Public Insults: The Effects of Public Provocation,Provocation Intensity,and Rumination on Triggered Displaced Aggression

Four studies present the first evidence showing that public (vs. private) provocation augments triggered displaced aggression by increasing the perceived intensity of the provocation. This effect is shown to be independent of face‐saving motivation. Following a public or private provocation, Study 1 participants were induced to ruminate or were distracted for 20 min. They then had an opportunity to aggress against another person who either acted in a neutral or mildly annoying fashion (viz. triggering event). As expected, the magnitude of the greater displaced aggression of those who ruminated before the triggering event compared with those distracted was greater under public than private provocation. Study 2 replicated the findings of Study 1 and confirmed that public provocations are experienced as more intense. Studies 3 and 4 both manipulated provocation intensity directly to show that it mediated the moderating effect of public/private provocation found in Study 1. The greater intensity of a public provocation increases reactivity to a subsequent trigger, which in turn, augments triggered displaced aggression. Aggr. Behav. 39:13‐29, 2013. © 2012 Wiley Periodicals, Inc.     

Anger rumination: an antecedent of athlete aggression?

Objectives. The aim of this study was to examine the relationship between anger rumination (the propensity to think almost obsessively over past experiences that have provoked negative affect in the form of anger) and athlete aggression. It was predicted that high levels of anger rumination would be associated with an increased propensity to aggress.Method. A questionnaire comprising the Anger Rumination Scale (Sukhodolsky, Golub, & Cromwell, 2001), aggression and demographic questions was distributed to 305 male and female competitive athletes of varying ability who represented several team and individual sports.Results. Principal component factor analysis revealed a single rumination factor rather than the four-factor solution previously described. No differences in Anger Rumination Scale score were found between males and females, team and individual sport players or competitive level. Provocation and anger rumination were significantly correlated with athletes’ reported aggressive behaviour. Aggression was higher in males compared to females. Type of sport was also related to incidence of aggression; athletes who participated in individual sports reported lower levels of aggression than athletes who played team sports.Conclusions. It was concluded that provocation and anger rumination were significant predictors of subsequent aggression and suggestions for preventing rumination, such as thought stopping and thought switching, were made.     

Effects of sex,status, and mating cues on expected aggressive responses

The effect of sex, status, and mating cues on expected aggression was examined via three scenario‐based studies in which participants imagined themselves in a situation with a same‐sex instigator of a provocation. Participants were randomly assigned to receive a scenario, which included one of two levels of status of instigator (high, low), one of two levels of attractiveness of the instigator (unattractive, attractive), and one of two levels of provocation (apology, insult). Sex and dispositional aggressivity were also included in a full factorial design. Based on evolutionary psychology ideas, we anticipated that status and attractiveness would differentially influence expected aggression for men vs. women. Participants in Experiment 1 were instructed to imagine that they were alone, whereas participants in Experiments 2 and 3 imagined themselves in a situation that included mating‐related primes. In general expected aggression was greater for aggression‐prone participants and under conditions of provocation and/or a high‐status instigator. Experiments 2 and 3 found that, in the context of mate competition, sex differences in the effects of instigator provocation, status, and attractiveness emerged: greater aggressivity now only predicted more aggression for males but not females who were insulted; aggression was highest for females confronting an unattractive, high‐status instigator and for males confronting an attractive, high‐status instigator; females were more likely to aggress against a high‐status instigator, regardless of being in a steady relationship or a first date situation, but males were only more likely to aggress against a high‐status instigator in a first date situation.

Mitigating circumstance information, censure, and aggression

One hundred men received one of two levels of mitigating circumstance information either before or after being insulted or not insulted by a co-worker. Participants were then provided with an opportunity ostensibly to deliver aversive noise to the co-worker under either high or low social censure conditions. Physiological data and self-report measures revealed that participants who learned of mitigating circumstance information before being provoked exhibited smaller increases in physiological arousal and reported less annoyance than did those who learned of mitigating circumstance information after insult. Aggression data showed that angered participants evaluated their provoker more favorably and retaliated less when they learned of mitigation before rather than after being insulted. These findings supported attribution theory assumptions that mitigating circumstance information known before the provoking incident influences the individual's interpretation of harm, thereby reducing anger and the instigation to aggression. The reduced impact of information on aggression that is acquired after provocation may reflect the provoked individual's shift of attention from cues surrounding harm to a consideration of inhibitory factors for aggression.     

Aggressive disposition,alcohol, and aggression

This study investigated the effect of aggressive disposition on intoxicated and non-intoxicated aggressive behavior. Prior aggressiveness was measured with a structured questionnaire. Based on a bipartite split of scores, 28 subjects were assigned to the high aggressor group, and 29 to the low aggressor group. Subjects in both disposition groups were then randomly assigned to either a drunk or sober condition, and participated in a competitive reaction time task involving the administering and receiving of electric shocks to/from a fictitious opponent under conditions of high and low provocation. Aggression was defined as shock level intensity delivered to the sham opponent. When highly provoked, sober high aggressors were significantly more aggressive than low aggressors, thus validating the measure of aggressive disposition. When intoxicated, highly provoked individuals in both the high and low aggressive disposition groups attained equal levels of aggression. It was low aggressors who responded to escalated provocation with a significant increase in aggression responding when intoxicated. These results lend support to the notion that a pharmacological effect of alcohol can increase aggressive behaviour. Aggr. Behav. 23:11–18, 1997. © 1997 Wiley-Liss, Inc.     

Mood Adjustment to Social Situations Through Mass Media Use: How Men Ruminate and Women Dissipate Angry Moods

Mood adjustment goals served to explain gender differences regarding media preferences. Before reacting to antagonism, females are likely to prevent aggression by dissolving aversive states through media consumption, whereas males could preserve aggression by choosing negative content. In a computerized procedure, participants (N = 86) were provoked by supervisor feedback to instigate angry moods. Half of the sample was led to anticipate a retaliation opportunity. In a purportedly separate study, participants were free to choose from online news while software unobtrusively logged their selective news exposure. The articles had been classified as positive or negative news in a pretest. When anticipating a retaliation opportunity, females spent more time reading positive news to dissipate their anger. Males expecting a retaliation opportunity spent more time on negative news to sustain their anger. Males’ generally lower news consumption, especially when anticipating a chance to retaliate, indicated anger rumination through news avoidance altogether.     

The Effects of Acute Alcohol Intoxication and Self-Focused Rumination on Triggered Displaced Aggression

An experiment simultaneously examined the effects of acute alcohol intoxication and self-focused rumination on triggered displaced aggression. An ethnically diverse sample of 97 young adult participants (41 men, 56 women) were recruited from a university community and surrounding area. Participants were provoked by an experimenter, randomly assigned to a 2 (alcohol, sober)?×?2 (rumination, distraction)?×?2 (trigger, no trigger) between-participants design, and then given an opportunity to aggress against an undeserving other who was either completely innocent or slightly annoying. Self-focused rumination increased displaced aggression only when participants were triggered by the slightly annoying participant. Alcohol independently augmented aggression.     

Do Big Five personality traits associated with self-control influence the regulation of anger and aggression?

This study examined whether Big Five personality traits associated with the ability to exhibit self-control would moderate the anger–aggression link. A total of 126 participants (63 women) completed personality measures. In a separate experimental session, participants wrote an essay and then received either positive or negative feedback from a fictitious participant. Participants were given the opportunity to aggress against the supposed other person. Baseline and post-experimental emotions were assessed. EEG was recorded to measure activity in midfrontal, lateral-frontal, and parietal areas. Results replicated previous findings that anger is associated with left relative to right prefrontal asymmetry and aggression. Conscientiousness was negatively associated with anger and relative left prefrontal asymmetry. Conscientiousness also moderated the link between anger and aggression. Agreeableness was positively associated with anger, but only when levels of conscientiousness were low.     

Attribution of apparent arousal and proficiency of recovery from sympathetic activation affecting excitation transfer to aggressive behavior

In a pretest, subjects' proficiency to recover from sympathetic arousal induced by strenuous exercise was assessed. The results were used to determine conditions of high, intermediate, and low recovery proficiency (fitness). After an assessment of subjects' unprovoked aggressiveness, subjects were aggressively provoked. Within proficiency blocks, they were then given one of two treatments, (a) sitting followed by exercising (no decay) or (b) exercising followed by sitting (partial decay), and were there-after provided with an opportunity to retaliate against their tormentor. Under conditions of no decay, in which the high levels of arousal experienced were attributable to exertion, the provocation treatment failed to increase aggressiveness significantly, and there were no differences in aggressiveness in the various proficiency conditions in spite of differentiations in the magnitude of prevailing excitatory residues. Under partial decay, in the absence of cues linking arousal to exertion, the magnitude of residual arousal did affect aggressive behavior: In the conditions of intermediate and low recovery proficiency, aggressiveness increased significantly with provocation and was more pronounced than in the condition of high proficiency (best fitness); in the condition of low proficiency (least fitness) aggressiveness was higher than in the condition of intermediate proficiency, but not reliably so.     

The Type A behaviour pattern,induced mood,and the illusion of control

This study investigated the hypothesis that mood moderates the illusion of control among Type As and Bs. A facial positioning procedure was used to induce either positive, negative, or neutral moods in Type As and Bs during a control judgment task where no objective control was possible. Type Bs induced to experience a positive mood perceived greater control than did Type Bs experiencing a negative mood. There was no effect of induced mood on judged control for Type As.     

The eliciting cue value of aggressive slides reconsidered in a personological perspective: The weapons effect and irritability

A study was conducted, according to a 2 × 2 × 2 × 3 design and using the Buss aggression machine paradigm, to investigate the aggression-eliciting properties of slides of firearms. One hundred and twenty highly irritable and 120 low irritable subjects, equally divided between males and females, were given the opportunity to deliver electric shocks to an experimental confederate after having been randomly assigned to one of the six different conditions resulting from presence versus absence of previous instigation to aggress and from exposure to aggressive slides versus exposure to non-aggressive slides versus non-exposure to slides. It was found that aggressive cues, were sufficient per se to increase subsequent aggressive behaviours in observers, whether or not previously instigated to aggress. While sex differences did not seem to play any relevant role, the importance of irritability was stressed, especially where exposure to aggressive slides followed a previous instigation to aggress.     

Violence restrained: Effects of self-regulation and its depletion on aggression

Aggressive impulses arise from many factors, but they are usually held in check by social norms for self-control. Thus, the proximal cause of aggression is often failure of self-restraint. In five studies, depleted capacity for self-regulation (caused by prior, even irrelevant acts of self-regulation) increased aggressive responding, especially after an insulting provocation. When participants were insulted and their self-regulatory strength was depleted (i.e., after completing previous tasks that required self-regulation), participants were more likely to aggress. When the urge to aggress was relatively weaker (i.e., when participants were not insulted), self-regulatory depletion did not increase aggressive behavior. This effect was moderated by trait self-control: Participants low in trait self-control were particularly likely to express intentions of behaving aggressively in response to provocation, whereas participants high in trait self-control did not express intentions of responding aggressively. Laboratory, autobiographical memory, and hypothetical responses confirmed the pattern.
