new scientific evidence refutes驳斥,反驳 the preconception预想,偏见 that testosterone睾丸素 causes aggressive, egocentric利己的, and 1 behavior. a study at the universities of zurich and royal holloway london with more than 120 experimental subjects has shown that the sexual 2 with the poor reputation can encourage fair behaviors if this serves to ensure one's own status. popular scientific literature, art, and the media have been attributing the roll of 3 to the arguably可论证地 best known sexual hormone for decades. research appeared to confirm this – the castration阉割,去势 of male rodents啮齿类 evidently led to a reduction in 5 among the animals. the prejudice thus grew over decades that testosterone causes aggressive, risky, and egocentric behavior. the inference from these experiments with animals that testosterone produces the same effects in humans has proven to be false, however, as a combined study by neuroscientist christoph eisenegger and 6 ernst fehr, both of the university of zurich, and economist michael naef of royal holloway in london demonstrates. "we wanted to verify how the hormone affects social behavior," dr. christoph eisenegger explains, adding, "we were interested in the question: what is truth, and what is myth?"

for the study, published in the renowned有名的 journal nature, some 120 test subjects took part in a behavioral experiment where the distribution of a real amount of money was 8. the rules allowed both fair and unfair offers. the negotiating partner could subsequently accept or decline the offer. the fairer the offer, the less probable a refusal by the negotiating partner. if no agreement was reached, neither party earned anything.

before the game the test subjects were administered either a dose of 0.5 mg testosterone or a corresponding placebo安慰剂,对照剂. "if one were to believe the common opinion, we would expect subjects who received testosterone to adopt aggressive, egocentric, and risky strategies – regardless of the possibly negative consequences on the 9 process," eisenegger 10.
