Document Summary

Evolutionary psychology: a field of study that focuses on the role of evolutionary processes (cid:523)especially darwin(cid:495)s natural selection(cid:524) in the development of adaptive psychological mechanisms and social behaviours in humans. Cooperation: one individual helps another and in doing somehow benefits. Altruism: and individual helps another, but in so doing accrues some cost. Aggression: has evolved as it facilitates survival, competition for mates and limited resources, research - areas with limited resources often is related to m ore aggression and fighting. Sociobiological theory: any social behaviour that ensures the survival of the young is adaptive because the young survive to pass on the genes t the next generation, social groups evolved to ensure the survival of the young. Emotional bonds between parents and between parents and children: the family: Division of labour provider/protector vs. nurturer: larger social networks: Example: the extended family, because the extended family can also help children survive.
