from an evolutionary perspective you would not aggress your own genes!!! Whatever inhibits your aggression to biological offspring does not inhibit your aggression towards step children... Evolutionary Psychology - Why gender differences? - males aggress to achieve and maintain status - because that will attract females - females aggress to protect offspring Is Aggression Innate? The Role of Testosterone - are there specific biological factors that influence aggression? - strong positive correlation between testosterone levels and aggression - men in jail have more testosterone than regular men - people suggested that men with more testosterone are more aggression but: - but correlation is not causation! - and aggression can cause temporary increases in testosterone The Role of Serotonin - The neurotransmitter serotonin appears to restrain impulsive acts of aggression. - Low levels of serotonin associated with high levels of aggression. 215: March 24, 2011

- finding that in a lot of mental health conditions (borderline personality disorder: associated with impulse control); they also have lower levels of serotonin (psychopathic people...). maybe serotonin does not cause aggression but it prevents inhibition of aggressive urges - Boosting serotonin can dampen aggressiveness. - But is the lack of serotonin an innate cause of aggression? Is Aggression Learned? - Aggressive behavior is strongly affected by learning. - Aggression can be positively as well as negatively reinforced. - Positive reinforcement : Aggression produces desired outcomes. -you realize when young that when you are aggressive you get what you want. therefore you will use it in the future - Negative reinforcement : Aggression prevents or stops undesirable outcomes. - when you are aggressive then people do not bother you (bully you); increases probability that you will be aggressive Punishment and Aggression - Punishment is most likely to decrease aggression when it: - immediately follows the aggressive behavior - is strong enough to deter the aggressor - is consistently applied and perceived as fair and legitimate by the aggressor - if child feels that they don’t deserve that punishment then it will increase their aggression RESEARCH EXAMPLE - Straus et al (1997) - researchers recorded the number of times in a week that children were spanked - if parents use aggression on you, you learn form them that this is a strategy in order to get desirable behaviors from others - child learns that aggression can yield desired outcomes for you (learn behavior and positive aspects about using this behavior) -

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
