Summary The hypothesis was examined that the more definite an individual's body image boundaries the more likely he is to manifest behavior in an interview situation indicating that he is in clear communication with himself and others. Boundary definiteness was measured by means of the barrier score derived from responses to the Rorschach blots. Trained interviewers evaluated 195 Ss with regard to three behavioral categories (communicativeness, awareness of own motives, clarity of identity). The results consistently supported the hypothesis.
