Effect of social challenges on men's testosterone levels, aggression and face perception
In competitive situations, men are supposed to respond with an increase in testosterone, and this may have consequences on social perception. Here, we investigated whether short-term changes in testosterone can be experimentally induced by exposing men to a computer fighting game. Men’s testosterone levels after the task were higher than before the task. However, a similar effect was found for an exercising task, and in a control condition. Thus, the competitive context did not turn out to be particularly provocative in terms of producing a testosterone response. In addition, changes in testosterone did not predict face assessments of potential rivals and attractive women.
