Area of Science:

• Psychology
• Criminology
• Neuroscience

Background:

• Alcohol consumption is linked to aggression.
• Understanding individual differences in this relationship is crucial.

Purpose of the Study:

• To investigate the link between heavy drinking and interpersonal aggression in men.
• To identify personality traits that predict aggressive behavior after drinking.

Main Methods:

• Experimental "parties" were conducted with male social drinkers.
• Participants were videotaped and coded for interpersonal aggression.
• Personality measures including socialization, self-control, and responsibility were assessed.

Main Results:

• Participants with a history of aggression and low self-control/responsibility showed increased interpersonal aggression after heavy drinking.
