Abstract

The motivation for social status drives behavior in competition. Levels of testosterone and cortisol, hormones related to status motivation, change in response to competition depending on various Person and Context factors. This study employed a novel, effort-based competitive task in which performance is determined by the willingness to endure physical discomfort to be a winner, a measure of individual differences in the motivation to compete, i.e., competitive will. Person factors (traits related to status motivation: competitiveness, power/dominance motivation, and achievement orientation) and Context factors (social presence and competition outcome) were tested as predictors of competitive will and hormone response to competition in men and women (N = 158). Results showed that a combination of "status motivation" traits significantly predicted competitive will performance. Individual differences in status motivation also interacted with competition outcome (win/loss) to predict the testosterone change associated with competition - for those who won, higher status motivation predicted higher testosterone change. During competition, cortisol levels increased in men and decreased in women, except for women who competed against men. Social context also influenced competitive will - for those who competed face-to-face, performance in the task was significantly and positively related to co-competitors' times, an effect interpreted as resulting from the psychological drive for social conformity. These results suggest that competitive behavior is driven by paradoxical motives for both social status and affiliation. And, these motives interacting with social context, appear to have important hormonal underpinnings.
