  • Testosterone
    • Male sex hormone testosterone is thought to influence aggression form a youg adult
      • Lindman et al. (1987) found that young males who behaved aggressively when drunk had highest testosterone levels that those who did not act aggressively.
      • Wagner  et  al.
        • Found that when a male mouse was catsrated, causing a reduction in their levels of testosterone, that their overal levels of aggression decreased. If the mouse was then give in testosterone their aggressions increased again
        • This would therefore suggest the  testosterone is an important hormone implicated in aggressive behaviour.
        • Evaluation
          • Humans are different from mice but same principles apply (evolutionary psychologist)can be slightly generalised.
    • Real world application
      • The presence of a stimulus like a gun or nine could trigger an increase in testosterone levels(seen as a threat) , which in turn increases aggressive behaviour
    • Gende Bias
      • Most testosterone levels are studied on males participants
        • Women with high testosterone levels had higher testosterone  levels had occupational status, possibly a as    a result of being more assertive.
    • Reductionism and biological mechanisms
      • The complexity of human social behaviour means tha a biological explanation for human aggression is insuffient on its own to explain all the many different aspects of aggressive and violent behaviour.
        • SLT - increase likelihood that aggressive behaviour  will observed and imitated
          • Positively reinforced
