This study had 27 psychiatrists watch a half hour film of a third year medical student talking with a patient. They were all psychiatric faculty in the UCLA School of Medicine and were trying to create a criterion for use in examinations within the School. The film was such that they could see the patient from the perspective of the interviewer.
