Nonverbal Leakage and Clues to Deception^†

Abstract

Abstract : Research relevant to psychotherapy regarding facial expression and body movement, has shown that the kind of information which can be gleaned from the patients words - information about affects, attitudes, interpersonal styles, psychodynamics - can also be derived from his concomitant nonverbal behavior. The study explores the interaction situation, and considers how within deception interactions differences in neuroanatomy and cultural influences combine to produce specific types of body movements and facial expressions which escape efforts to deceive and emerge as leakage or deception clues.
