In judo,Randori (free fight) and Kata (highly ritualized fight) differentially change plasma cortisol,testosterone, and interleukin levels in male participants

Two forms of competitive encounters namely Randori (free fight) and Kata (highly ritualized fight) were studied in 22 professional male judo fighters. The dyadic, symmetrical (in terms of body weight and fighting ability) encounters were videotaped to assess relationships between agonistic behavior and individual variations in plasma levels of testosterone (T), cortisol (C) and interleukins (IL‐6 and IL‐1β) measured before and after the competition. Unremarkably, winners showed longer attack but devoted less time to defensive behaviors when compared to losers. T increased only during Randori but the individual pre‐ and post‐competition T levels recorded in such fights were strongly correlated with the corresponding measures in the Kata for the same individuals. Interestingly, the pre‐ and post‐Randori competition T levels were higher in losers than in winners and T variations positively correlated with the frequencies of attacks and with the duration of defensive postures. The T response shows individual variation and seems to reflect evaluation of the likelihood of winning or losing. Both Randori and Kata induced a marked C increase, although the pre‐ and post‐Randori hormonal titers were higher than those found for the Kata. IL‐6 significantly increased between the pre‐ and the post‐Randori competition, but no such changes occurred during the Kata. No correlations were found between individual pre‐ and post‐competition C and IL‐6 and IL‐1β levels in either Randori or Kata. This suggests that C and cytokine release are unrelated to emotional or cognitive perception of the possible outcome of fighting but are a consequence of general motor activity. Martial arts appear to provide good human models to understand: (a) the relationships between conflict, hormones and the immune system and (b) the relationships between mood and physiological responses to competitive aggression.

Behavioral and self‐reported aggression as a function of domain‐specific self‐esteem

On the basis of a domain‐specific theory of self‐esteem, it was hypothesized that functionally distinct domains of self‐esteem would predict aggression differentially. Participants completed self‐report measures of self‐perceived superiority, mate value, social inclusion, and global self‐esteem, as well as of aggression. Self‐assessed mate value emerged as a reliable, positive predictor, and social inclusion as a reliable inverse predictor, of self‐reported hostility and aggression. In a subsequent laboratory experiment, in which participants had an opportunity to aggress against the source of positive or negative feedback about a personal essay that they had written, mate value again predicted increased aggression, whereas global self‐esteem predicted decreased aggression. These main effects were moderated by the feedback manipulation, such that their respective simple effects were only present among participants that received negative feedback. Aggr.

The reactive–proactive aggression questionnaire: differential correlates of reactive and proactive aggression in adolescent boys

This study reports the development of the Reactive–Proactive Aggression Questionnaire (RPQ), and the differential correlates of these two forms of aggression. Antisocial, psychosocial and personality measures were obtained at ages 7 and 16 years in schoolboys, while the RPQ was administered to 334 of the boys at age 16 years. Confirmatory factor analysis indicated a significant fit for a two‐factor proactive–reactive model that replicated from one independent subsample to another. Proactive aggression was uniquely characterized at age 7 by initiation of fights, strong‐arm tactics, delinquency, poor school motivation, poor peer relationships, single‐parent status, psychosocial adversity, substance‐abusing parents, and hyperactivity, and at age 16 by a psychopathic personality, blunted affect, delinquency, and serious violent offending. Reactive aggression was uniquely characterized at age 16 by impulsivity, hostility, social anxiety, lack of close friends, unusual perceptual experiences, and ideas of reference. Findings confirm and extend the differential correlates of proactive–reactive aggression, and demonstrate that this brief but reliable and valid self‐report instrument can be used to assess proactive and reactive aggression in child and adolescent samples.

A Taxonomy of Anger-Related Behaviors in Young Adults

In 2 studies, we investigated the occurrence of anger-related behaviors and their relationship to emotional, performance-related, and situational variables. In the first study, we constructed a comprehensive taxonomy of behaviors associated with anger, and we examined the occurrence of the resulting behavior categories as a function of several independent variables. A total of 8 distinct behavior categories were identified, 3 aggressive and 5 nonaggressive. Our results also demonstrated that fight (including both verbal and physical aggression) and flight behaviors occurred most frequently. Physical aggression, however, occurred most frequently in an inhibited form, in response to the emotion of anger (as compared to the emotion of irritation), and when the anger was intense. A second study was conducted to replicate and extend the findings of Study 1. The results suggest that the taxonomy, as derived in Study 1, is comprehensive and allows for a reliable categorization. Moreover, it appeared that fight and flight behaviors occurred most frequently if the target at whom one is angry was present. The following reduction rules were used: (a) responses that differed only in the order of the words were put together; (b) singular and plural items were joined; (c) responses that differed only in verbs such as “to be,” “to become” or “to do” were grouped together; (d) responses that differed only syntactically (verb, noun or adjective) were grouped together; (e) responses that differed only with respect to an article, a preposition, or a possessive word were grouped together; (f) and a few specific rules were used (e.g., yourself = myself; self = auto). The complete coding manual is available upon request from the first author. This number differed across proportions because it depended on the number of participants assigned to each of the experimental questionnaires. Our initial analyses contained a participant-specific random intercept, so as to take into account individual differences in the propensity to use each of the behavior categories. Inclusion of a random intercept appeared to yield a significant improvement in model fit for two of the eight behavior categories. However, because analyses with a random and with a fixed intercept yielded similar conclusions, we decided to select the most parsimonious model, namely the one without a random intercept. The total number of participant–performance–instrumentality combinations equals 504 (i.e., 84×6) because all 84 participants had to answer six questions.

A daily diary investigation of self-reported alcohol-related direct and indirect aggression

Research supports the relationship between alcohol use and direct aggression, however, scant research has examined the association between alcohol use and indirectly aggressive behavior. Further, extant research has relied on retrospective reporting of behaviors, which may be subject to recall bias. The daily diary methodology enables the assessment of both the between- and within-subject variation, as well as reduces the likelihood of biased reporting. Consequently, the current study utilized a daily diary design to examine (a) associations between daily alcohol use and alcohol-related aggressive behaviors (i.e., direct and indirect); and (b) the co-occurrence of alcohol-related direct and indirect aggression. Participants were 105 (80% female) college student drinkers. Students completed baseline questionnaires and up to 14 consecutive, daily surveys regarding their previous day alcohol use, alcohol-related direct aggression, and alcohol-related indirect aggression. Findings revealed that alcohol use was associated with same day alcohol-related direct and indirect aggression, after controlling for baseline alcohol use. Self-reported alcohol-related direct aggression was more likely to occur on days in which self-reported alcohol-related indirect aggression occurred, after controlling for dispositional aggression, trait self-control, and baseline alcohol use. Results of the study suggest that, similar to alcohol-related direct aggression, alcohol use is associated with an increased likelihood of alcohol-related indirect aggression. Further, the co-occurrence of alcohol-related indirect and direct aggression supports that individuals may be engaging in multiple types of aggressive behaviors. Findings extend previous cross-sectional and qualitative research suggesting that indirect aggression may co-occur, perhaps increasing in severity.     

Aggression against middle and high school teachers: Duration of victimization and its negative impacts

Prior research indicates that student aggression against teachers is widespread, and it has negative impacts on victimized teachers’ emotional and physical well-being and job performance. However, little is known about the relationship between the recency and duration of victimization and teachers’ thoughts about quitting the teaching profession and related job dissatisfaction and disconnectedness to school. Analyses of data from a longitudinal study of 1,236 US teachers fills these gaps. The study found that many teachers experienced theft/vandalism and sexual harassment victimization that was limited to just 1 year. In contrast, sizeable proportions of teachers experienced verbal abuse and nonphysical contact aggression that occurred over 2 years. Multiple regression analyses showed that teachers who reported recent or multiyear victimization had lower levels of connectedness to school, less job satisfaction, and more thoughts about ending their teaching careers. These results may indicate that unless victimization recurs, negative effects of victimization are contemporaneous and are less likely to persist. Additional research is needed to examine victimization over longer than 2 years, investigate the effects of the frequency of different types of aggression against teachers, and identify school policies and interventions that weaken the connection of victimization to negative outcomes.
