Although aggression can be de fi ned in different ways and a dichotomy might be somewhat simplistic, in the current paper we use reactive and proactive aggression as a distinction in aggression type Reactive aggression is a form of aggression as a reaction on a provocation and most of ten char-acterized by hostility. Information pro-cessing de fi cits are implicated in this type of aggression and may be associated with cognitive and perceptual features of the psy-chotic illness that lead to reactive aggression. Proactive aggression is a so called cold-blooded form of aggression and of ten motivated by external reward. Therefore, besides its association with reactive ag-gression, psychopathy is also associated with proactive aggression.
