In this study, the effects of an experimental-induced provocation on emotions and aggression were examined in 34 aggressive conduct-disordered children using a competitive reaction time paradigm. Two experimental conditions were created, an increasing provocation and a low constant provocation condition. Self-rated anger was assessed directly after provocation on a 5-point-visual scale. In addition, negative and positive emotions as well as physiological measures (heart rate and skin conductance level) were measured at baseline and after provocation. Results revealed that participants’ aggressive behaviour and subjective emotions differed as a function of the opponent’s level of provocation. Concerning physiological parameters, no significant differences were found between the experimental conditions. These results suggest that affective, but not physiological variables characterize reactive aggression in conduct-disordered children.
