Some factors affecting the reduction of overt hostility.

2 assumptions were tested to explain observations that initial expressions of aggression may be followed by decline in such unfriendly attitudes. The "symbolic catharsis hypothesis" assumes the reduction of hostile attitudes due to vicarious (fantasy) expression of hostility; guilt theory assumes inhibition, rather than reduction, of hostile atitudes. Ss were fed information, supposedly opinions of each other, which encouraged unfriendly or friendly attitudes. Ss were then either allowed to associate to TAT cards or fed additional information so as to be made to feel guilty about unfriendly attitudes towards the other. Results were interpreted as supporting the guilt hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Expression of feeling and cognitive reinterpretation in the reduction of hostile aggression.

90 male college students were first angered by a confederate's critical evaluation of their autobiographical letters. They were then given 1 of 3 procedures designed to reduce hostile aggression: an expression of their feelings to the confederate; a reinterpretation of the criticism by the confederate; and a combination of expression and reinterpretation. In comparison to a hostility induction, no-reduction control group, and a no-hostility-induction control group, the combination of expression and reinterpretation produced a significant reduction in hostile aggression as measured by A. H. Buss's aggression machine and changes in verbal hostility ratings. Neither expression alone nor reinterpretation alone produced significant reductions in aggression.

Interpersonal aggression and the Type A coronary-prone behavior pattern: A theoretical distinction and practical implications.

In Study 1, 85 male undergraduates were classified as Type A (coronary prone) or Type B (noncoronary prone) on the basis of scores on the Jenkins Activity Survey. Ss participated in a version of A. H. Buss's (1961) teacher–learner procedure that allowed the isolation of hostile from instrumental acts. Results indicate that a prior task frustration produced greater aggression by Type A's than Type B's, but only under conditions where the aggressive act could not affect a confederate's immediate performance (i.e., hostile aggression). Study 2 examined the representation of Type A's and Type B's among 20 women in treatment for child abuse, 20 women who were victims of spouse abuse, and 20 control women. Findings show that Type A's were more likely than Type B's to exhibit the extreme hostility found in child abuse. Both studies suggest that a lack of control may underlie the greater aggression displayed by Type A's and Type B's. (39 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stress-induced asymmetric frontal brain activity and aggression risk.

Impersonal stressors, not only interpersonal provocation, can instigate aggression through an associative network linking negative emotions to behavioral activation (L. Berkowitz, 1990). Research has not examined the brain mechanisms that are engaged by different types of stress and serve to promote hostility and aggression. The present study examined whether stress exposure elicits more left than right frontal brain activity implicated in behavioral approach motivation and whether this lateralized brain activity predicts stress-induced aggression and hostile/aggressive tendencies. Results showed that (a) participants in the impersonal (assigned to stress by a computer) and interpersonal (assigned to stress by a provoking confederate) stress conditions both showed more left than right frontal electroencephalogram activity after condition assignment and stress exposure and (b) the 2 stress groups exhibited subsequent increases in aggression relative to the no-stress group. Importantly, left frontal asymmetry in response to stress exposure predicted increases in subsequent aggressive behavior, a finding that did not emerge in the no-stress condition. Thus, both the interpersonal and impersonal stressors impacted state changes in brain activity related to behavioral approach, suggesting that stress reactivity involving approach activation represents risk for behavioral dysregulation.

Pain cues and differing functions of aggression.

64 male undergraduates served in an experiment designed to demonstrate that the functional value of aggression (prosocial or hostile) determines the effect of potential antecedents (provocation) and reinforcers (victim's pain cues) of aggression on responses in the teacher-learner paradigm. Results support the hypothesis that provocation facilitates hostile aggression and reduces prosocial aggression. It was also hypothesized that high pain cues are reinforcing only for provoked Ss under hostile conditions. Contrary to this 2nd hypothesis, however, results indicate that high pain cues reduced aggression in all conditions.

Negative family environment as a predictor of boy's future status on measures of hostile attitudes, interview behavior, and anger expression.

The present study tested the hypothesis that family environments characterized as nonsupportive, unaccepting, and conflictual lead to the development of hostile traits in adolescent Caucasian boys. Negative behaviors during parent–son discussions aimed at resolving disagreements were observed in a laboratory setting in 51 intact families. Sons' hostile traits were assessed at the time of the interactions and then 3 years later. Results showed that a high frequency of negative behaviors exhibited by both parents and sons predicted sons' later hostile attitudes and outward expression of anger after adjustment for their initial level of hostile attitudes and anger expression, respectively. A low frequency of positive behaviors exhibited by the father and son predicted sons' later Potential for Hostility ratings after adjustment for their initial level. The meaning of these findings for the conceptualization of hostility is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Resting respiratory sinus arrhythmia buffers against rejection sensitivity via emotion control.

Emerging evidence suggests that high resting heart rate variability in the respiratory frequency band, or respiratory sinus arrhythmia (RSA) may capture individual differences in the capacity to engage in situationally appropriate regulation of affect and behavior. The authors therefore hypothesized that high RSA may act as a protective factor against difficulties controlling negative affect and hostile behaviors in conflicts with romantic partners in highly rejection-sensitive individuals--a population otherwise vulnerable to these responses. Results were consistent with this hypothesis such that highly rejection-sensitive participants reported less emotion control and more hostility in conflicts only if they were also low in RSA. Furthermore, emotion control mediated the joint effect of rejection-sensitivity and RSA on hostile conflict behavior. These results are consistent with the argument that resting RSA is a marker of flexible responding in the context of highly emotional situations, and further suggest that it may serve as a protective factor particularly in vulnerable populations.

Exposure to violent media: The effects of songs with violent lyrics on aggressive thoughts and feelings.

Five experiments examined effects of songs with violent lyrics on aggressive thoughts and hostile feelings. Experiments 1, 3, 4 and 5 demonstrated that college students who heard a violent song felt more hostile than those who heard a similar but nonviolent song. Experiments 2-5 demonstrated a similar increase in aggressive thoughts. These effects replicated across songs and song types (e.g., rock, humorous, nonhumorous). Experiments 3-5 also demonstrated that trait hostility was positively related to state hostility but did not moderate the song lyric effects. Discussion centers on the potential role of lyric content on aggression in short-term settings, relation to catharsis and other media violence domains, development of aggressive personality, differences between long-term and short-term effects, and possible mitigating factors.

Social-information-processing factors in reactive and proactive aggression in children's peer groups.

In Study 1, a teacher-rating instrument was developed to assess these behaviors in elementary school children (N?=?259). Reactive and proactive scales were found to be internally consistent, and factor analyses partially supported convergent and discriminant validities. In Study 2, behavioral correlates of these forms of aggression were examined through assessments by peers (N?=?339). Both types of aggression related to social rejection, but only proactively aggressive boys were also viewed as leaders and as having a sense of humor. In Study 3, we hypothesized that reactive aggression (but not proactive aggression) would occur as a function of hostile attributional biases and intention-cue detection deficits. Four groups of socially rejected boys (reactive aggressive, proactive aggressive, reactive-proactive aggressive, and nonaggressive) and a group of average boys were presented with a series of hypothetical videorecorded vignettes depicting provocations by peers and were asked to interpret the intentions of the provocateur (N?=?117). Only the two reactive-aggressive groups displayed biases and deficits in interpretations. In Study 4, attributional biases and deficits were found to be positively correlated with the rate of reactive aggression (but not proactive aggression) displayed in free play with peers (N?=?127). These studies supported the hypothesis that attributional biases and deficits are related to reactive aggression but not to proactive aggression.

Marital aggression, observed parental hostility, and child behavior during triadic family interaction.

This study used direct observation to examine how a history of exposure to interparental aggression relates to children's behavior during conflict with both parents present. Ninety 2-parent families with a child 9–13 years of age participated. Consistent with a sensitization hypothesis, results indicated that exposure to interparental physical aggression during the previous year was related to child withdrawal, anxiety, and distraction during a family discussion task. In addition, the interaction between reported interparental aggression and observed child-directed hostility accounted for significant variance in boys' behavior. Follow-up correlation analyses revealed that boys who had been exposed to physical marital aggression were more anxious and distracting when their parents were more hostile toward them during the discussion, whereas boys who had not been exposed withdrew more.

Cardiovascular and emotional responses in women: The role of hostility and harassment.

The relation of hostility and harassment to cardiovascular and emotional responses was examined by having 51 women (aged 18–26 yrs) high and low in hostility complete a task with or without harassment. Harassed high hostile Ss showed greater systolic blood pressure (SBP) increases during task and recovery periods than did harassed low hostile Ss and nonharassed Ss. Harassed low hostile Ss evidenced greater SBP increases during task and recovery periods than did nonharassed Ss. Among high hostile women, cardiovascular elevations during the task were associated with self-reported levels of negative affect. Antagonistic hostility, relative to neurotic hostility, was positively associated with harassment-induced SBP changes. These results support the hypothesis that hostile people exhibit excessive behaviorally induced cardiovascular responses to interpersonally challenging tasks that evoke anger-related emotional states.

Associative and spontaneous appraisal processes independently contribute to anger elicitation in daily life.

There has been a great deal of debate concerning the antecedents of anger, with appraisal theorists emphasizing the role of hostile interpretations and cognitive neo-associationistic theorists emphasizing the role of more basic associative processes. Recently, theorists have sought to reconcile these views by acknowledging the role of both associative and inferential processes, and the current investigation drew upon recent social–cognitive research to test this compromise. Individual differences in hostile inferences and associations were assessed in an implicit cognitive paradigm, and relevant outcomes were assessed in a daily diary protocol. Implicit hostile inferences predicted both anger and aggression in daily life, and such relationships were mediated by propensities toward hostile interpretations in daily life. Hostile associations also predicted anger in daily life, but this relationship proved to be independent of daily hostile interpretations. Results therefore support a model that acknowledges the role of both associative and appraisal processes in anger elicitation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Status restoration and the reduction of hostility.

"The present study reports positive results on a test of the implications of a 'threat' theory of hostility, namely, that hostility is reduced by status restoration. Essentially, the experiments deals with techniques designed to restore the status or the integrity of the S, who has been subjected to the hostile arousing conditions, without permitting expression of aggression (catharsis or communication)."

Hostility and smoking cessation treatment outcome in heavy social drinkers.

Hostility is a multifaceted construct encompassing affective, behavioral, and cognitive aspects. There is preliminary evidence linking hostility to poorer outcomes in smoking cessation treatment; however, it is unclear which components of hostility are most important in cessation. In this study, the authors examined multiple aspects of trait hostility in 92 heavy social drinkers who were seeking smoking cessation treatment. Consistent with their hypothesis, the authors found that the cognitive component of hostility was most relevant to smoking cessation outcome. Specifically, those who expressed bitterness about their lives and tended to believe that they had poor luck and had gotten a raw deal out of life had poor smoking cessation outcomes. Cognitive measures of hostility also predicted greater nicotine withdrawal symptoms 1 week after quitting smoking. Other components of hostility including anger and both physical and verbal aggression did not significantly predict smoking outcome or nicotine withdrawal. Further examination of how a hostile worldview contributes to smoking cessation failure is warranted, as this facet of hostility may prove a valuable target for smoking cessation interventions.

Age differences in hostility among middle-aged and older adults.

Multiple measures of hostility were administered to middle-aged and older volunteers. There was a positive association between age and self-report measures reflecting hostile beliefs about others, including cynicism and suspiciousness. There was a weak inverse relationship between age and self-report measures of the overt expression of anger and aggression, but no association between age and measures of covert hostility was found. There was a positive relationship between age and an assessment of hostile behavior that was based on the respondent's interaction style during an interview. The magnitude of these age trends did not differ between men (n?=?50) and women (n?=?75). Findings illustrate the multidimensional nature of hostility. They also have practical implications for older people because hostility is associated with psychological well-being and has been shown to have consequences for health and longevity.

Projection of hostility on the TAT as a function of stimulus, background, and personality variables.

The effects of stimulus, background, and personality factors on the TAT were examined. Stimulus was measured by scaling the TAT for hostility and background by use of 2 instructional sets, "look your best" and "impersonal," and personality, by selecting via pooled rankings, 96 college men and women from an initial sample of 802 who were extremely hostile or friendly (group judgments) and who thought of themselves as hostile or friendly. Hypotheses that hostile persons would not project more hostility than friendly persons, but persons with hostile self-concepts would project more hostility than persons with friendly self-concepts were confirmed. The stimulus was the most important determinant of response, and low and medium hostile cards better than highly hostile ones in discriminating groups.

Anxious uncertainty and reactive approach motivation (RAM).

In 4 experiments anxious uncertainty threats caused reactive approach motivation (RAM). In Studies 1 and 2, academic anxious uncertainty threats caused RAM as assessed by behavioral neuroscience and implicit measures of approach motivation. In Study 3 the effect of a relational anxious uncertainty threat on approach-motivated personal projects in participants' everyday lives was mediated by the idealism of those projects. In Study 4 the effect of a different relational anxious uncertainty threat on implicit approach motivation was heightened by manipulated salience of personal ideals. Results suggest a RAM account for idealistic and ideological reactions in the threat and defense literature. Speculative implications are suggested for understanding diverse social and clinical phenomena ranging from worldview defense, prejudice, and meaning making to narcissism, hypomania, and aggression.

Dimensions of hostility and aggression in abnormal offenders.

Analyzed the scores of 165 male inpatient psychiatric offenders on 17 hostility and personality scales (e.g., the MMPI). 4 factors were extracted, identified as aggression, hostility, introversion-extroversion, and age. Hostility and aggression were found to be notably oblique to each other and slightly negatively correlated with introversion-extroversion. However, the hostility factor was also identifiable as the neuroticism dimension. None of the factors could be identified as intropunitiveness-extropunitiveness, and the variance of the scales measuring these attributes was spread over the 1st 3 factors. It is concluded that 2 broad dimensions of aggressive response tendency and hostile evaluation may be sufficient to describe this area of behavior. (35 ref.)

Vitality and interest–enjoyment as a function of class-to-class variation in need-supportive teaching and pupils' autonomous motivation.

In 2 quasi-experimental field studies in a real-life physical education (PE) setting, the authors investigated whether the interest–enjoyment and vitality of Greek pupils (age range, 10–12 years) varied from class to class as a function of the class-to-class variation in the manipulated motivational environment (Studies 1 and 2) and pupils' relative autonomous motivation (Study 2). In Study 1, multilevel analyses showed at the within-student level that students (N = 138, 48.6% boys and 51.4% girls) reported, on average, more interest–enjoyment and vitality after a need-supportive, relative to a typical (i.e., control group), PE class. This main effect was replicated in Study 2 (N = 155, 53.6% boys and 46.4% girls), and Study 2 findings further showed at the between-student level that interest–enjoyment was somewhat higher among pupils scoring higher in relative autonomous motivation. Moreover, Study 2 provided evidence for an interaction effect such that pupils with high, as compared with those with low, relative autonomous motivation benefited significantly more from a need-supportive class. Perceived need support was found to fully explain the effects of manipulated need support on interest-enjoyment and vitality. Results are discussed within the self-determination theory (Deci & Ryan, 2000). (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Sense of humor as a moderator of the relation between stressors and moods.

Three studies, conducted with 143 undergraduates, are reported that investigated the hypothesis, long held by theorists, therapists, and laypersons alike, that a sense of humor reduces the deleterious impact of stressful experiences. In each study a negative-life-events checklist was used to predict stress scores on a measure of mood disturbance. These studies made use of different measures of Ss' sense of humor, including 4 self-report scales and 2 behavioral assessments of Ss' ability to produce humor under nonstressful and mildly stressful conditions. Hierarchical multiple regression analyses revealed that 5 of the 6 humor measures produced a significant moderating effect on the relation between negative life events and mood disturbance. Ss with low humor scores obtained higher correlations between these 2 variables than did those with high humor scores. Results provide initial evidence for the stress-buffering role of humor.
