Do we inherit aggressive …show more content…
For example, testosterone and need for dominance in some men. Testosterone, an androgen, is a type of naturally occurring steroid hormone which is secreted into the bloodstream in spurts, meaning levels of testosterone can change considerably within minutes and changes from individual to individual. A research study conducted by Snowdon states that aggressive behaviours are higher in males who are trying to assert dominance, trying to acquire resources, trying to attract and to acquire a mate or to just be seen as a dominant figure. In these circumstances, dominant acting individuals who hold subordinate roles are relatively likely to break restrictive norms and codes of conduct to assert themselves. (Snowdon, 1998). Testosterone also works differently throughout different times in our lives, some of the major changes in our testosterone levels occur throughout puberty and in times of adulthood. However little evidence can be found when linking testosterone with puberty and adulthood. A study conducted by Kreuz and Rose (1972), studied 21 male prisoner aged 18 to 35, they found no significant testosterone difference between those who fought a lot while in prison and those who did not fight while in prison; however, prisoners with a prior record of violent and aggressive crimes and behaviours had significantly higher testosterone levels than those without such a history. This article therefore show there is little correlation between testosterone in most men and the levels of aggression demonstrated, however aggression levels can be higher in certain men exerting higher levels of testosterone. Therefore when linking nature to testosterone levels and the aggression that is produced, you
