Document Summary
Social psychology: the study of how people influence other peoples thoughts, feelings and actions. People favor their own groups: automatic categorization > changes to perception. People readily identify in-groups, to which they belong and outgrips to which they do not. In-group and outgrips to which they do not belong. In-group and outgrip formation and maintenance are affected by reciprocity and transivity. Outgroup homogeneity effect: the tendency to view outgrip members as less varied than ingroup members. People also tend to dehumanize members of outgrips. Social identity theory: the idea that ingroups consist of individuals who perceive themselves to be members of the same social category and experience pride through their group membership. In-group favoritism: the tendency for people to evaluate favorable and privilege members of the in-group more than members of the outgroup. Reciprocity: if person a helps person b, person b will help person a. Transitivity: friends having the same opinions toward other people.
