Identifying component-processes of executive functioning that serve as risk factors for the alcohol-aggression relation.

The present investigation determined how different component-processes of executive functioning (EF) served as risk factors for intoxicated aggression. Participants were 512 (246 males and 266 females) healthy social drinkers between 21 and 35 years of age. EF was measured using the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) that assesses nine EF components. After the consumption of either an alcohol or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities and durations administered to the opponent. Although a general BRIEF-A EF construct consisting of all nine components predicted intoxicated aggression, the best predictor involved one termed the Behavioral Regulation Index that comprises component processes such as inhibition, emotional control, flexible thinking, and self-monitoring.

Executive functioning, irritability, and alcohol-related aggression.

The purpose of this investigation was to examine (a) whether irritability mediates the relation between executive functioning (EF) and alcohol-related aggression and (b) whether the alcohol-aggression relation is better explained by the interactive effects of EF and irritability above and beyond the effects of either variable alone. EF was measured using seven well-established neuropsychological tests. Irritability was assessed with the Caprara Irritability Scale. Participants were 313 male and female social drinkers between 21 and 35 years of age. Following the consumption of an alcohol or a placebo beverage, participants were tested on a laboratory aggression task in which electric shocks were given to and received from a fictitious opponent under the guise of a competitive reaction-time task. Aggression was operationalized as the shock intensities administered to the fictitious opponent. Results indicated that irritability successfully mediated the relation between EF and intoxicated aggression for men only. Despite the fact that irritability and EF both independently moderated the alcohol-aggression relation in previous studies, no significant interaction for their combined effect was detected here. The findings are discussed, in part, within a cognitive neoassociationistic framework for aggressive behavior.

Men and women, alcohol and aggression.

The purpose of this study was to examine the acute effects of alcohol on aggressive behavior in men and women in a laboratory setting. Participants were 526 (261 men and 265 women) healthy social drinkers between 21 and 35 years of age. They were randomly assigned to either an alcohol or a placebo group. Aggression was measured using a modified version of the Taylor Aggression Paradigm in which electric shocks are received from, and delivered to, a same gender fictitious opponent during a supposed competitive interpersonal task. Aggression was operationalized as the intensity and duration of shocks that participants administered to their "opponent." Overall, men were more aggressive than women. Alcohol increased aggression for both men and women but this effect was stronger for men. This is one of the first laboratory studies to demonstrate that alcohol increases aggression in women.

Perceptions of one's attacker's intentions following an aggressive interaction involving alcohol.

The authors investigated and assessed the perceptions of one's attacker's intentions following an aggressive interaction involving alcohol. Participants were 328 (163 men and 165 women) healthy social drinkers between 21 and 35 years of age. After participants had consumed a beverage containing either alcohol or a placebo, the authors tested them on a modified version of the Taylor Aggression Paradigm (TAP; S. Taylor, 1967) in which participants received mild electric shocks from, and administered shocks to, a fictitious opponent (the attacker) under the guise of a competitive task. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent. The authors queried participants about their perceptions of their opponents' intentions toward them on the task. Overall, participants who were least aggressive on the TAP perceived their opponent to have the most aggressive intentions and those who were the most aggressive perceived their opponent to have the least aggressive intentions. Alcohol only seemed to play a role for women. It appeared to decrease aggressive perceptions for the least aggressive women and to increase such perceptions for the most aggressive women. The authors discuss results according to L. Huesmann's (1988) cognitive script model of aggression.

"So I can't blame the booze?": Dispositional aggressivity negates the moderating effects of expectancies on alcohol-related aggression.

OBJECTIVE: The purpose of this study was to determine the effects of alcohol expectancies on intoxicated aggression in men and women while controlling for dispositional aggressivity. METHOD: Subjects were 328 (163 men and 165 women) healthy social drinkers between 21 and 35 years of age. Alcohol expectancies were measured using items from a variety of validated self-report inventories. Following the consumption of either an alcohol or a placebo beverage, subjects were tested on a modified version of the Taylor Aggression Paradigm, in which mild electric shocks were received from and administered to a fictitious opponent during a competitive task. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent under conditions of low and high provocation. RESULTS: On their own, alcohol expectancies played a limited role in impacting aggressive behavior. Specifically, alcohol expectancies were significantly related to aggression for men who received the placebo beverage under low provocation and for men who received alcohol under high provocation. A significant main effect of alcohol expectancies was also detected. However, all of these effects were rendered nonsignificant when controlling for dispositional aggressivity. It is important to note that the main effect for beverage group remained significant after controlling for dispositional aggressivity. CONCLUSIONS: Taken as a whole, this pattern of findings suggests that intoxicated aggression is primarily the result of alcohol's pharmacological properties in conjunction with an aggressive personality.
