PSYCHOANALYTIC:
Focuses on the unconscious motives of the person in terms of Id, Ego, and Superego.
Therapy may involve hyponesis, free association, and dream analysis.
HUMANISTIC:
Focuses on the value, dignity, and worth of each person.
Therapy may involve non-directive therapy, active listening, unconditional positive regard, such as calling your patient a "client" to show equality.
COGNITIVE: (does not include social)
Focuses on the way people think.
Therapy may involve rational-emotive therapy, which helps change unrealistic assumptions of onself,
I couldn't find social, but if it's similar, I have a section on:
BEHAVIOR:
Focuses more on a person's actual behavior rather than their thoughts.
Therapy may involve counter-conditioning, which is pairing a stimulus (positive thing) with good behavior, to encourage that behavior more often.
