Abstract :
[en] We investigated how playing a violent versus non-violent video game affects cortisol and testosterone levels, whether these hormonal changes increase implicit aggressive cognition, and whether so-called Dark Tetrad personality traits (i.e., Machiavellianism, psychopathy, narcissism, everyday sadism) moderate these effects). Fifty-four men played either a violent or a non-violent video game for 25 minutes. Participants provided salivary samples at the beginning of the experiment (T1), after 25 minutes of gameplay (T2), and 20 minutes after gameplay ended (T3). In the violent condition, participants showed a significant decrease in cortisol levels (T1 to T2) and a significant negative trend in cortisol levels from T1 to T3. Moreover, higher Machiavellianism scores were related to a significantly stronger decrease in cortisol (T1 to T2) in this condition. In the non-violent condition, however, participants with higher scores in Machiavellianism had a higher increase in cortisol (T1 to T2). In contrast to changes in hormonal levels, there were no significant effects on implicit aggressive cognition. The present findings illustrate the complex interplay between personality, hormones, and game content, thus further specifying current notions on the effects of violent video games. Playing a violent video game can have a stress-reducing calming effect depending on personality traits such as Machiavellianism and the psychological need satisfaction associated with it. Also, the fact that VVG exposure was not automatically accompanied by an aggression-increasing effect proves that simple cause-effect models are not sufficiently specified without taking the underlying mechanisms into account.
