- Hormonal Theories of Aggression
- AO1
- Serotonin
- Serotonin in normal levels within the prefrontal cortex inhibits aggressive tendencies & has a calming influence on behaviour
- Serotonin
- AO1
- Dopamine
- The link between dopamine and aggression is not as strong but it is believed that increases in dopamine activity are associated with increases in aggressive behaviour
- This indicates a positive relationship between the two
- However, dopamine increases as a result of aggression, not a cause
- Dopamine is a pleasure chemical which floods D2 receptors when do something rewarding, making us want to repeat that action
- Brains find aggressive acts rewarding, so individuals likely to repeat the behaviour
- Explaining the the increase in dopamine levels

- Vervet monkeys fed on an experimental diet high in tryptophan exhibited a decrease in aggressive behaviour
- While others fed a diet low in tryptophan exhibited high levels of aggressive behaviour
