1. What factors may have driven the neighbors of Perley Farm to pitch in and help clean up after the fl ood? We have touched on some of the major ideas, research topics, and experimental fi ndings of social psychology.

We examined how people form, maintain, and change attitudes and how they form impressions of others and assign attributions to them. We also saw how groups, through conformity and tactics of compliance, can infl uence individuals’ actions and attitudes.

Finally, we discussed interpersonal relationships, including both liking and loving, and looked at aggression and prosocial behavior, the two sides of a coin that represent the extremes of social behavior.
