Cognitive therapy (CT) is a kind of psychotherapy that treats problematic behaviors and distressing emotional responses by identifying and correcting unhelpful and inaccurate patterns of thinking. This involves the individual working with the therapist to develop skills for testing and changing beliefs, identifying distorted thinking, relating to others in different ways, and changing behaviors.
Cognitive therapy is based on the cognitive model (which states that thoughts, feelings, and behavior are connected), with substantial influence from the heuristics and biases research program of the 1970s, which found a wide variety of cognitive biases and distortions that can contribute to mental illness.
