Social behavior

In biology, psychology and sociology social behavior is behavior directed towards society, or taking place between, members of the same species. Behavior such as predation which involves members of different species is not social. While many social behaviors are communication (provoke a response, or change in behavior, without acting directly on the receiver) communication between members of different species is not social behavior.

In a sociological hierarchy, social behavior is followed by social action, which is directed at other people and is designed to induce a response. Further along this ascending scale are social interaction and social relation. In conclusion, social behavior is a process of communicating.
