Abstract
A class of 145 college students was given Barber's Creative Imagination Scale (CIS) and Spiegel's Eye Roll Sign, and later given several opportunities to volunteer for research projects, some of which specified hypnosis was involved. Those S's who volunteered for the hypnosis experiments took the Harvard Group Scale of Hypnotizability (HGSHS). Hypnosis volunteers differed from the non-hypnosis volunteers by significantly higher grades and more total experimental volunteerism, but were not significantly different on the CIS or Eye Roll Sign. In general, nonwhites scored higher on the CIS. Among hypnosis volunteers, there was a low negative correlation between HGSHS:A Consciousness scale and volunteering for experiments other than hypnosis.
