Concept
Personal construct theory
Summary
Within personality psychology, personal construct theory (PCT) or personal construct psychology (PCP) is a theory of personality and cognition developed by the American psychologist George Kelly in the 1950s. The theory addresses the psychological reasons for actions. Kelly proposed that individuals can be psychologically evaluated according to similarity–dissimilarity poles, which he called personal constructs (schemas, or ways of seeing the world). The theory is considered by some psychologists as forerunner to theories of cognitive therapy.
From the theory, Kelly derived a psychotherapy approach, as well as a technique called the repertory grid interview, that helped his patients to analyze their own personal constructs with minimal intervention or interpretation by the therapist. The repertory grid was later adapted for various uses within organizations, including decision-making and interpretation of other people's world-views. The UK Council for Psychotherapy, a regulatory body, classifies PCP therapy within the experiential subset of the constructivist school.
A main tenet of PCP theory is that a person's unique psychological processes are channeled by the way s/he anticipates events. Kelly believed that anticipation and prediction are the main drivers of our mind. "Every man is, in his own particular way, a scientist", said Kelly: people are constantly building up and refining theories and models about how the world works so that they can anticipate future events. People start doing this at birth (for example, a child discovers that if they start to cry, their mother will come to them) and continue refining their theories as they grow up.
Kelly proposed that every construct is bipolar, specifying how two things are similar to each other (lying on the same pole) and different from a third thing, and they can be expanded with new ideas. (More recent researchers have suggested that constructs need not be bipolar.) People build theories—often stereotypes—about other people and also try to control them or impose on others their own theories so as to be better able to predict others' actions.
