The social, psychological and neurobiological factors that contribute to the link between alcohol consumption and increased aggression have been identified by scientists.
Reduced cognitive control resulting from heavy alcohol consumption narrows perception and so can lead to an increased proneness to violent behavior in certain situations.
According to current research by Anne Beck and Andreas Heinz, additional factors include personal expectations of the effect of alcohol and previous violent confrontations.
In men in particular, the influence of alcohol strengthens the conviction that violence and aggression are acceptable forms of social interaction. However, environmental conditions in early childhood, such as social discrimination, are further risk factors.
Therapeutic approaches have been developed to combat this alcohol-induced aggression. These are specific therapies that aim to increase cognitive and emotional control.
The study was presented in Deutsches Arzteblatt International.
