ABSTRACT This study was designed to test the hypothesis that a stress set or no set (uncertainty) would produce greater arousal in sensory deprivation (SD) than a relaxation set. The role of a diurnal (a.m. vs p.m.) factor was also evaluated. Eighteen male subjects were run in a 3 hour SD condition in the morning, and 18 were run in the afternoon. One third of the subjects were given a stress set emphasizing the stressful and peculiar effects of SD, one third were told nothing, and one third were told that the study was on the effects of “relaxation”. Heart Rate, Breathing Rate (BR), Skin Conductance, and Nonspecific GSR fluctuations (NS‐GSRs) were measured before and during the SD condition. BR was higher in the stress set group than in the other set groups. NS‐GSRs were higher in the stress set and no set groups than in the relaxation set group. Subjects showed more reaction on both of these measures in the afternoon than in the morning.
