The role of interpersonal rapport in facilitating the enhancements in hypnotizability produced by cognitive skill training was examined in two experiments. In Experiment 1 low hypnotizable subjects either received skill training or passively oriented training that was designed to facilitate rapport with the trainer without teaching subjects how to generate the responses called for by test suggestions. Subjects in the two treatments reported equivalently high levels of rapport with their trainer, but only those given skill training attained large gains on two hypnotizability posttests. Subjects given passive training did not differ from untreated controls at posttesting. In Experiment 2 subjects received skill training under conditions designed to either heighten or minimize rapport with the trainer. Those in the high rapport condition showed large hypnotizability gains on both posttests, whereas those in the low rapport condition failed to differ from no treatment controls in this regard. Our findings indicate that high rapport is not sufficient for producing training-induced enhancements in hypnotizability. However, the absence of such rapport may interfere with subjects' learning and applying skills that can enhance hypnotizability.Hypnotizability test scores usually remain relatively stable even after long retest intervals, when no systematic attempts have been made to alter subjects hypnotic responsiveness [1] . Relatedly, numerous studies which attempted to enhance hypnotizability by training subjects in relaxation, meditation, or other procedures designed to alter consciousness usually produced only small and often nonsignificant increments in hypnotizability [see 2 for a review] . Taken together, these fmdings have led some investigators to conceptualize *
