A social skill is any skill facilitating interaction and communication with others. Social rules and relations are created, communicated, and changed in verbal and nonverbal ways. The process of learning such skills is called socialization. The rationale for this type of an approach to treatment is that people meet a variety of social problems and can reduce the stress and punishment from the encounter as well as increase their reinforcement by having the correct skills.
