Document Summary

Person dependence it depends on the type of person you are. Interdependent: happiness depends on the happiness of others. Losers i(cid:374)(cid:272)rease testostero(cid:374)e (cid:272)o(cid:373)pared to wi(cid:374)(cid:374)er (e. g. wi(cid:374)(cid:374)ers were surprised (cid:271)y result, do(cid:374)"t want to compete again) Testosterone increased aggressive behavior in men with low trait self control but not among men with high trait self-control. Men high in dominance trait increased testosterone but not men with a trait low in dominance. The dual-hormone hypothesis testostero(cid:374)e"s effe(cid:272)t o(cid:374) status-seeking behaviors should depend on cortisol levels. (high stress decreases reproduction) High (cid:272)ortisol (cid:373)ay (cid:271)lo(cid:272)k testostero(cid:374)e"s i(cid:374)flue(cid:374)(cid:272)e o(cid:374) status-seeking behaviors. Possible mechanisms : neurobiological, psychological, evolutionary, testosterone positively related to dominance only when cortisol is low, high testosterone, low cortisol individuals had the highest place in the social hierarchy (popular people), this is also common in risk takers. Testosterone can also increase prosocial status-seeking behaviors, not just aggressive ones (reconciliation after a match)
