The effects of hypnosis and of imagery on bleeding time: a brief communication.

2 studies are reported, one using hypnotized Ss selected on hypnotizability and one using Ss selected on imagery vividness, whose purpose is to examine whether non-patient Ss can control their bleeding in a laboratory setting. All Ss were cut on both arms with the "Surgicutt" device, an instrument that automatically makes a cut that will bleed from 2 to 10 minutes. Results suggest that Ss, who are instructed to reduce the bleeding time in one arm and to let the other arm bleed normally, are not able to control bleeding time.

Hypnotic age-regression and magnitudes of the Ponzo and Poggendorff illusions.

The effect of hypnotically induced age-regression on the magnitudes of the Ponzo and Poggendorff illusions was determined for ten college students. The results, when compared with normative developmental data, are more typical of younger ages than of the chronological ages of the subjects.
