Two studies are reported which examined physiological responsiveness to changes in level of nonverbal intimacy cues expressed by a partner during an interview conducted across interactive television. Experiment 1 and Experiment 2 separately examined the effects of decreasing apparent interactive distance (produced by alteration of image size) and increasing eye-contact on subjects' heart rate and pulse amplitude. The findings suggest that shifts in these nonverbal approach cues are related to cardiovascular changes including bradycardia and a modest compensatory increase in pulse amplitude. The implications of these results are discussed in terms of the hypothesized relationship between cardiovascular functioning and information processing and practical considerations for the use of interactive television.
