A renewed look at Miller's conflict theory of aggression displacement.

The present study is the first to examine Miller's theoretical assumptions of displaced aggression using human subjects. Subjects in the present study either served as nonangered controls, were angered by the experimenter's confederate, or were both angered by and led to fear the confederate. All subjects were then able to three targets: the confederate, a person described as a friend of the confederate, and a person having no association with the confederate. Targets received the most intense aggression from angered subjects. The difference between the aggression gradients for high-anger-low-fear and control subject. Frightened subjects gave their most intense aggression to the displaced targets. Results also support the suggestion that direct aggression is most likely if the aggressor can first extinguish some of his fear by attacking more indirect targets.     

The Jenkins Activity Survey measure of type a and frustration-induced anger

The present study examined the physiological and self-report responses of Type A and B males, defined by the Jenkins Activity Survey (JAS), to an anger-inducing frustration manipulation. Subjects jointly performed a task with a confederate and either were or were not frustrated by the confederate in their attempt to gain a prize. Physiological and self-report measures indicated that the frustration manipulation generated anger, but there was no evidence that Type A subjects were more angered than Type B subjects. Such findings may reflect a weakness in the Jenkins Activity Survey for adequately measuring the hostility component of the Type A pattern.The research reported here was supported by a Biomedical Sciences Support Grant RRO 7037 to the second author.     

Effects of viewing real versus fantasy violence upon interpersonal aggression

Of 96 male undergraduates, one-third saw a violent film which they were told represented a real event, one-third saw the same film presented as a fictional event, and the remaining subjects saw no film. One-half of the subjects in each group had been attacked previously by a confederate while the others had not. Each subject was then given an opportunity to aggress against the confederate by administering shocks to him as punishment in a learning task. Results indicate that subjects who observed real violence delivered stronger shocks to the confederate than subjects who viewed fantasy violence or saw no film. Subjects who were angered and saw the real film were the most punitive toward the confederate.     

The aggression-inhibiting influence of nonhostile humor

Forty undergraduate students participated in an experiment designed to investigate the hypothesis that prior exposure to nonhostile humor would markedly reduce the level of aggression directed by angry individuals against the person who had previously provoked them. In order to examine this suggestion, subjects were first angered or not angered by a confederate of the experimenter, then exposed to either humorous cartoons or nonhumorous pictures, and finally provided with an opportunity to aggress against this individual by means of electric shock. Results indicated that exposure to the nonhostile cartoons significantly reduced the duration of the shocks delivered to the confederate by subjects in the angry condition, but failed to influence the level of aggression demonstrated by subjects in the nonangry group. These findings were discussed in terms of the elicitation, by the cartoons, of responses and emotional states incompatible with anger or overt aggression. Possible implications of the aggression-inhibiting influence of humor for the prevention and control of human violence were also considered.     

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.     

The effects of humor-induced arousal upon aggressive behavior

The present experiment attempted to reconcile previous results in the area of humor and aggression. It was hypothesized that humor serves two functions, arousal and attentional shift, with regard to its influence on the relation of prior anger arousal and aggression. As a test of this assumption, subjects in the present experiment were subjected to three forms of humor (high arousing, low arousing, nonhumor) after being angered or treated in a neutral manner by a confederate. In an analysis on subsequent aggression toward the confederate, it was found that female subjects reduced their aggression after exposure to low arousing humor while maintaining aggression at a high level for high arousing stimuli. Male subjects were not influenced by humor exposure. Possible reasons for this sex difference are examined in light of the arousal and attentional shift properties of humorous stimuli.     

Effects of observing competitive and violent versions of a sport

Males were randomly assigned to view either (1) a film clip featuring hockey fights or (2) a film of nonaggressive hockey action or (3) a no-film control condition after having first been angered or treated politely by an experimental confederate. The dependent variable was represented by a measure of aggressive mood and a behavioral measure of retaliatory aggression. Analyses revealed that both angered and nonangered subjects exhibited an increase in aggressive mood following exposure to the fight film. However, the analysis involving retaliatory aggression against the confederate yielded an anger x film interaction. While angered subjects were more aggressive than nonangered, only angered subjects retaliated against the confederate after viewing the fight film. The results were discussed in terms of Berkowitz’s (1974) aggressive cue theory. A version of this paper was presented at the meeting of the North American Society for the Sociology of Sport, Edmonton, Canada, November 1987.

Facilitation of social interaction through deindividuation of the target

It was hypothesized that actors want their perception of a target to be consistent with the type of interaction they expect. It was predicted that subjects expecting to aggress would deindividuate their target through the selective recall of deindividuating information. Conversely, subjects expecting a prosocial interaction should individuate the target. Further, angry subjects should deindividuate the individual who angered them. Male subjects were either angered or not angered by an experimental confederate and then given the opportunity to either shock, reward, or have no interaction with him. Subjects recalled information about the confederate either prior to or after the learning task. Subjects expecting to aggress deindividuated the target, whereas subjects expecting a prosocial interaction individuated him. Angry subjects deindividuated the target, nonangry subjects did not. Since the selective recall of information occurred prior to the interaction, the deindividuation (individuation) was aimed at facilitating future behavior rather than justifying it.     

Aggression-inhibiting influence of sexual humor

Forty-eight undergraduate males participated in an experiment designed to investigate the hypothesis that prior exposure to sexual humor would reduce the level of aggression directed by angry individuals against the person who had previously provoked them. In order to examine this suggestion, subjects were first angered or not angered by a male confederate; next, exposed to either neutral, nonhumorous pictures or to one of two types of sexual humor (nonexploitative, exploitative); and finally, provided with an opportunity to aggress against this individual by means of electric shock. Results indicated that exposure to exploitative sexual humor, but not exposure to nonexploitative sexual humor, significantly reduced the strength of subjects' later attacks against the victim. These findings are discussed in terms of the results of a follow-up study suggesting that individuals are more likely to think or fantasize about exploitative than nonexploitative sexual humor following the removal of such stimuli.     

Task-related arousal of type A and type B persons: level of challenge and response specificity

To determine whether different levels of challenge had differential effects on the arousal levels of Type A and Type B persons, 30 Type A and 30 Type B male subjects worked on an intelligence test task (digits backwards recall) that was easy, moderately difficult, or extremely difficult. Arousal was measured in terms of systolic blood pressure, diastolic blood pressure, pulse rate, pulse volume, skin resistance, and subjective arousal. Results indicated that while working on the extremely difficult task, the Type A subjects evidenced reliably higher systolic blood pressure than did the Type B subjects (p = 0.1; difference = 7.52 mm of Hg) and that there were not reliable differences between the subjects in systolic blood pressure at other levels of challenge or on other measures of arousal.     

Hostile aggression and type A behavior

Type A and Type B male college students were given the opportunity to display hostile aggression against an insulting confederate on a bogus ESP task, using either aversive noise or a monetary penalty. Preliminary correlational analyses confirmed that Ss' aggressive responding covaried directly with their reported desire to hurt the confederate but was, in contrast, unrelated to their reported desire to help the confederate. Thus, Ss' aggressive behavior was motivated by hostile intentions. Subsequent analyses revealed that Type As were more aggressive and reported a greater desire to hurt the confederate than Type Bs, regardless of the mode of aggression. These data support the results of a recent study which questioned the intuitively appealing assumption that Type As should only display aggressive behavior when motivated by some external achievement goal.     

Annoyance, type and duration of postannoyance activity, and aggression: the "cathartic effect".

A series of experiments was conducted to elucidate the conditions conductive to a decrease in aggression following annoyance. The potential capacity of expression of aggression to bring about a reduction in the amount of subsequent aggression was of particular interest. This empirical concern was supplemented by tests of several influential and competing theoretical concepts dealing with the cathartic aspects of human aggressive behavior. Given the failure of such concepts to account for major portions of the data, an integrative theoretical model was proposed. experiment 1 evaluated the usefulness of the hydraulic, self-arousal, and dissipation of anger concepts in accounting for the earlier demonstrations of the cathartic effect. In a 2 x 3 x 2 design, half of the subjects were annoyed by a confederate, while the other half were treated neutrally. During the next stage (the interpolated period), a third of all subjects gave "shocks" to the confederate, another third simply waited, while the remaining third worked on mathematical problems. Orthogonal to the first two facotrs was the duration of the interpolated period (7 to 13 min). The main dependent measure was the number of shocks administered to the confederate in the final stage of the experiment. It was found that annoyed subjects gave more shocks than nonannoyed ones did, and that only the former were substantially affected by other manipulations. In the case of the annoyed wait and annoyed math subjects, the anger dissipation hypothesis correctly predicted that the mere passage of time would decrease the amount of subsequent aggression, presumably due to the action of homeostatic processes. The self-arousal hypothesis correctly predicted that the annoyed math subjects would give fewer shocks than the annoyed wait ones would. Since the subjects were engaged in an absorbing activity, the likelihood of their arousing themselves by ruminations about the preceding annoying incident was minimized, and the amount of subsequent aggression reduced. Yet, when annoyed subjects had given the confederate a moderate number of shocks in the interpolated period, they subsequently gave him fewer shocks than the 7-min annoyed wait and annoyed math subjects; this was the only outcome predicted correctly by the hydraulic model. In contrast, when a large number of shocks had been administered in the interpolated period, the amount of subsequent aggression was relatively high. The interpretation of the latter result in terms of an "adaption effect" was tested by further experiments.     

Heightened sexual arousal and physical aggression: An extension to females

In order to examine the effects of heightened sexual arousal upon aggression by females, subjects were first angered or not angered by a female confederate, next exposed to one of four types of stimuli (nonerotic scenes; pictures of seminude young males; pictures of nude males; pictures of couples engaged in various acts of lovemaking), and finally provided with an opportunity to aggress against the confederate by means of electric shock. In accordance with previous research conduced with males, it was hypothesized that exposure to mild erotic stimuli would inhibit subsequent aggression, while exposure to more arousing stimuli of this type would facilitate such behavior. Results offered support for both predictions. In addition, it was found that females responded with increased aggression to types of erotic stimuli previously found to inhibit such behavior by males.     

Anger arousal,deindividuation, and aggression

We tested the notion that angered persons' aggression would be increased through a process of excitation transfer when they are deindividuated, but that individuated subjects would be most aggressive in circumstances under which they could use the information that they had ingested an arousing drug as a pretext for their aggression. Sixty-two male undergraduates participated under either deindividuated or individuated conditions, ingested either 350 mg of caffeine or a placebo, were informed that they had either taken a stimulant or a nonarousing drug, and were all angered by a confederate. According to prediction, when deindividuated and aroused by caffeine the amount of noxious stimulation subjects delivered to the provocateur was greater if they believed that the drug they had taken was nonarousing than if they thought it was a stimulant; in contrast, individuated subjects' aggression was greater when aroused subjects believed the drug was a stimulant. The results are discussed in terms of excitation transfer and the effect of aggression inhibition on the use of information about one's arousal.     

Dynamics of hostile aggression: Influence of anger,hurt instructions,and victim pain feedback

The research basically examined some of the dynamics of hostile aggression by looking at the effects of different Buss procedure instructions and levels of victim pain feedback on the aggressive behavior of angered and nonangered men. In a 2 × 2 × 2 completely crossed factorial experiment, male undergraduates were initially either angered or not by an experimental accomplice. When later given the ostensible opportunity to administer shocks to the same accomplice in a typical Buss procedure, the subjects were either told that longer and more intense shocks would probably interfere with the person's learning as well as causing him more pain (hurt instructions) or given no information about the effects of shocks on learning (standard instructions). Finally, after each shock they administered, the subjects were provided with either high or low victim pain feedback. The angered men were significantly more aggressive than their nonangered counterparts, and a significant interaction between anger and instructions indicated this was especially true for the men given hurt instructions. Significant interactions between the other independent variables and trial blocks revealed that the angered men, particularly those receiving hurt instructions and high victim pain feedback, displayed the greates increases in aggression. The results provide qualified support for the derived proposition about hostile aggression that signs and/or knowledge of victim injury and pain can stimulate more intense aggression from angry individuals.     

Immediate and delayed effects of victim suffering on the attacker's aggression

On the first day of a two-day experiment, male undergraduates were either angered or not, and they were given either high, low, or no metered pain feedback after each shock they supposedly delivered to their previous evaluator for his errors on a learning task. After the learning task the subjects made a number of ratings, including how much they had enjoyed this first session. On the second day, all subjects were simply required to administer shocks to a different person for his mistakes on the same learning task. The angered subjects were more punitive on both days toward both learners than the nonangered men. On the first day the angered men also increased the intensity of the shocks they delivered over trial blocks. Most interestingly, the angered men showed more enjoyment of the first session of the experiment as their victim's pain increased, and this enjoyment rating was related to the angered subjects' level of aggression on the second day of the experiment when they punished an “innocent” victim. The results were interpreted as consistent with the hypothesized reinforcement process which essentially states that signs and/or knowledge of the victim's suffering can reinforce impulsive or angry aggressive behavior.     

Cheating,intention, and punishment from an equity theory perspective

Male college students were given the opportunity to deliver aversive noise to a partner (confederate) contingent on the partner's “mistakes” in a learning task. Subjects were either not informed about a reward or told that they, their partner, or a charity would receive a monetary reward for speedy learning. Half of the subjects observed the confederate cheat, while half did not observe any deceptive behavior. The intensity of punitive behavior seemed to vary in accordance with predictions derived from equity theory. That is, cheating for a charity, a “good cause” resulted in less intense punishment than did cheating for selfish gain. On the other hand, mistakes, uncomplicated by cheating, which deprived a charity were punished more intensely than were mistakes whose only result accrued to the confederate himself.     

Identification with film characters, covert aggressive verbalization, and reactions to film violence

To determine some conditions governing the aggressive aftereffects of identification with aggressive film characters, men were first angered by a confederate and then exposed to a film clip of a violent boxing match. Subjects instructed to identify with the winner of the prize-fight were subsequently more aggressive toward the confederate than subjects instructed to identify with the loser or subjects not asked to identify with a film aggressor. Apparently, viewers must perceive their identificand incur reinforcement for his aggression before they become more aggressive themselves. However, requiring subjects to make implicit aggressive verbalizations during the film completely eliminated any aggressive aftereffects of identification. This finding was opposite to prediction and suggested that covert verbalization interfered with subjects' ability to make the vicarious aggressive responses which mediate increased subsequent aggression.     

Evaluation of a fortuitously reward other

Under the guise of an experiment on gambling decisions, subjects briefly met a confederate of the experimenter, whom they later evaluated. The major hypothesis was that the confederate would be evaluated more favorably by subjects who were told that she had received a fortuitous reward than by control subjects. The hypothesis was confirmed for female subjects only.
