A failure to replicate alcohol-induced laboratory aggression among college men without evidence of personality disturbance.
The effect of acute alcohol intoxication on laboratory-induced aggression among men has been fairly well established. The present study hypothesized that alcohol effects on Point Subtraction Aggression Paradigm (PSAP) responding would not be replicated among "low-risk' college men distinguished by their absence of personality disorder features. Participants were assigned to either Alcohol (n=18), Placebo (n=7), or Time (n=8) comparison groups with each completing 25-min. sessions during the baseline, ascent, peak (70 mg%), and descent (40 mg%) phases of absorption and elimination process. Participants assigned to the Alcohol condition received a .80 ml/kg dose of 95% ethanol mixed with soda in a 1:5 ethanol/soda ratio. As hypothesized, alcohol was associated with stable Point Subtraction Aggression Paradigm responding across the course of absorption, peak, and elimination for all three groups. Aggression Paradigm responding was least variable among the men administered alcohol. The present procedure served to identify a subset of "low-risk" college men whose Point Subtraction Aggression Paradigm responding was not adversely affected by alcohol. The extent to which aggressive personality dispositions contribute to alcohol-induced laboratory aggression remains to be identified. Low-risk college drinkers warrant systematic examination to specify what factors attenuate their reactions to alcohol and other situational provocations.
