During human interactions, rhythmic synchronization is often observed between the body movements of interacting partners. We have referred to this synchronization as ‘body movement synchrony’. A number of studies have suggested that body movement synchrony during psychological counseling is closely related to rapport and empathy. A novel computer-based analysis was applied to evaluate body movement synchrony during psychological counseling, and the relationship between synchrony and the quality of counseling was analyzed. The intensity of the participants’ body movement was respectively measured using a video-based system. The cross-correlation function between the two time series of the intensity was used as the body synchrony index. We analyzed two educational counseling sessions by a junior high school teacher and a school counselor, and four psychotherapeutic counseling sessions using this system. Results of both types of counseling sessions indicated that body movement synchrony was observed when experts rated the counseling session positively, but not when they rated it negatively.
