Cooperation among individuals depends upon both the goal structure of the situation and the cooperative skills of the individuals. Since cooperation is probably the most important and basic form of human interaction, the skills of cooperation successfully are some of the most important skills a person needs to master. Cooperative skills include the skills of: (1) self-disclosing to and building trust with others; (2) communicating effectively with others; (3) influencing and supporting others; and (4) managing conflicts constructively. Basic to the establishment and stabilization of cooperation are the skills of communicating cooperative intentions and expectations and building trust. Effective communication depends upon both sending and receiving skills and the building of trust depends upon the skills of reciprocating a person's disclosure of information, ideas and feelings, and the communication of acceptance of his disclosures.
