Document Summary
Peak of t during territorial conflict/ fighting to mate (aggressive behaviour) Puberty=rise in testosterone but not necessarily overall rise in aggression (inconsistent results but higher instance of man/man aggression in higher phase of t) Aggression=higher in men than women (and higher t levels) T and sex: rise when aroused or engaged in sexual behaviour. T and competition: rise in t during, especially when they win associated with display of aggressive behaviour. Lower t levels in monogamous species, increase t more polygamous behaviour (study on relationships) Non human primates: dominant males have most access to resources/mating and they display highest levels of aggression and t (idea: when you"re in this position you"re challenged often so high testosterone needed to react and defend territory) However in humans: little evidence between display of aggressive behaviour and baseline level of t. T in brain (both men and women): brain activity in places that facilitate aggressive behaviour (last class, e. g. amygdala)
