In 1955, clinical psychologist and educator George Kelly introduced his psychology of personal constructs. Kelly’s constructs were based on the idea that each individual looks at the world through his or her own unique set of preconceived notions about it (i.e., constructs). These constructs change and adapt as the individual is exposed to new and different situations. At the heart of Kelly’s theory is the idea that individuals can seek new experiences and practice and adapt new behaviors in order to change their attitudes (or constructs) towards the world. He recommended that therapists encourage their patients to try out new behaviors and coping strategies; he and others that followed frequently found that patients would adapt these useful new behavior patterns and subsequently change their attitudes.
