Document Summary
1: aggression: behaviour intended to harm another person, can be physical or psychological harm, video: guy bullying the other person. Illustrates different hostile and instrumental forms of aggression. Where does aggression come from: plato: it"s human nature , aristotle: it"s learned . Genetic links: males are more overtly aggressive than females, relatively universal and consistent across cultures, when unprovoked, sex differences depend on type of aggression, physical more likely in males, relational more likely in females. E. g. spreading rumours, exclusion: twin studies, around 50% of variance in aggression explained by genes, dopamine acts both directly and indirectly, direct, can increase feeling of reward that we regress, reduces our ability to inhibit aggression. Indirect: more reactive to life stressors; we feel better when good things happen, we feel much worse when bad things happen. 2: may still be modeled by those punished, social learning theory: people (young people especially) model what they see, including aggression, novel aggressive behaviors learned this way.
