The document outlines 5 types of social interaction: exchange, competition, conflict, cooperation, and accommodation. Exchange involves individuals or groups interacting to receive a reward for their actions based on principles of reciprocity. Competition involves two or more opposing groups trying to achieve a single goal through accepted rules, while conflict deliberately tries to control or harm others with few rules. Cooperation has groups working together for mutual benefit. Accommodation balances cooperation and conflict through compromise, mediation, truce, or arbitration between opposing parties.
