Self-control training decreases aggression in response to provocation in aggressive individuals

One common cause of aggression is self-control failure, yet research suggests that practicing self-control over time can improve subsequent self-control. This experiment tested whether self-control training over a 2-week period could decrease anger and aggression in response to provocation. Seventy undergraduates completed 2 weeks of self-control training or a control task. At the end of the 2 weeks, participants were insulted and given the opportunity to retaliate by delivering a blast of loud white noise. Self-control training reduced aggression among those high in trait aggression. Participants who received the training also reported less anger than those in the control condition. These results provide initial support that self-control training might prove beneficial for assisting aggressive individuals to overcome aggressive impulses.
