Going on stage: Testosterone in greetings and meetings

This research explored the relation of endogenous tesrosterone levels to be havior in brief social encounters. In four studies, 358 college students wh ose testosterone levels were known entered a room and (1) stood and spoke t o a video camera, (2) stood and talked with an experimenter. (3) sat and ta lked with an interviewer, or (4) sat and talked with a peer. High-testoster one students entered more quickly, focused more directly on their targets, and displayed a more forward and independent manner. Results were similar f or men and women. Correlates of testosterone are visible in thin slices of everyday behavior lasting only a few seconds. The effect of this behavior o n a social interaction partner remains to be determined.
