Provided by Wikipedia Robert Joseph Langs (June 30, 1928 – November 8, 2014) was a psychiatrist, psychotherapist, and psychoanalyst. He was the author, co-author, or editor of more than forty books on psychotherapy and human psychology. Over the course of more than fifty years, Langs developed a revised version of psychoanalyticpsychotherapy, currently known as the "adaptive paradigm". This is a distinctive model of the mind, and particularly of the mind's unconscious component, significantly different from other forms of psychoanalytic and psychodynamic psychotherapy.
