Recently, there have been several convincing demonstrations that nonverbal behaviors are key elements in influencing client judgments of counselor credibility. A study was conducted to examine the sensitivity of the self-reported reliance on nonverbal behaviors, as assessed by the Verbal/Nonverbal Reliance Questionnaire (VNRQ), to the actual changes in nonverbal behaviors. Two stimulus tapes, one tape containing counselor responsive and the other counselor unresponsive nonverbal behaviors, were developed and shown to 127 high school students. The students rated the expertness, trustworthiness, and attractiveness of the counselor, and indicated the degree to which they relied on nonverbal cues (eye contact, smile, voice, and gestures) in making their judgments. The results indicated that participants who reported a higher reliance, in contrast to a lower reliance, on nonverbal cues showed a greater sensitivity to changes in nonverbal behaviors. The findings suggest that self-reported reliance on nonverbal behavior, as measured by the VNRQ, may be a sensitive and convenient method of obtaining information about the contribution of nonverbal behavior in a client's perception of the counselor.
