- Evolutionary function - increased likelihood of offspring, access to resources and mates.
- Nature or nurture - hormones (testosterone, serotonin), brain regions (prefrontal cortex) - environment (peers, games), learning theory (reward aggression)
- Gender differences in aggression - males more physically, females more indirectly
- Prefrontal cortex and serotonin - impulse control - underpinned by serotonergic neurons
- Monkeys with lowest serotonin turnover are more aggressive
- Low 5-HT (precursor to serontonin) in humans = higher agression and suicide
- Induced tryptophan depletion = higher aggression
- Social learning theory - rewarded or punished behaviour
- Bobo doll - agression replication and immitation
- Twin studies - Suggesting that environmental similarities are more important in early life but that genetic factors ultimately over- rule?
