Self-control is the ability to control one’s emotions, behavior, and desires in the face of external demands in order to function in society. In psychology it is sometimes called self-regulation. Self-control is essential in behavior to achieve goals and to avoid impulses and/or emotions that could prove to be negative. In behavior analysis self-control represents the locus of two conflicting contingencies of reinforcement, which then make a controlling response reinforcing when it causes changes in the controlled response.
