Obedience to the demands or orders of others differs from compliance in that it is often a response to direct pressure or a specific request, rather than an intrinsic desire to fit into a group. Obedience occurs in informal situations that require authority, such as when a friend persuades the other to change his or her behavior. In interpersonal communication, compliance is part of the power and persuasion dynamic, showing how personal influence can change the behavior of others.
