The basic concept of perceptual control theory (PCT), as developed by William T. Powers, is that perceptions are the only reality or knowledge of the outside world that one can experience. That being the case, the purpose of all behavior is to control our perceptions of one's world. PCT helps to understand that all human beings are always trying to achieve the wants or goals of their choice. They do this by thinking and making plans and by behaving to influence some variable in the outside world. By providing a different way of thinking about problemsolving, PCT helps those who work with juveniles, as well as juvenile clients, see what is happening in their lives as living control systems. More importantly, it helps juvenile staff understand what can be done to guide juvenile offenders to make more positive choices in their thinking and behaviors by learning to solve their own problems in positive, responsible, and legal ways. The emphasis is on the types of questions, thought processes, and problemsolving skills that are intended to keep the juveniles in control of their perceptual worlds. In this way they are assisted in learning internal control skills that will transfer back with them into their communities. The juveniles will then have the tools to accept responsibility for themselves, their perceptions, and their behaviors. 12 references
