Document Summary

At all ages, men are more willing to compete and take risks than women: what you will risk is greater in men, what they will risk for, younger for women, older for money, related to testosterone levels. Role of testosterone in competition/aggression: angry faces make the heartrate go up in men. In the presence of high levels of testosterone, men feel challenged: when you do win, testosterone goes up and you are more likely to compete again. Low levels of testosterone less giving, don"t understand fairness. Testosterone: challenge hypothesis: winning raise testosterone higher self-esteem more competitive, high testosterone levels lead one to think that they are always right, testosterone is challenging, rewarding, and activating, testosterone levels can be measured in saliva. In men, testosterone levels went up if his preference won and levels went down if his preference lost: no changes in women.
