Placebo Effect upon Complex Reaction Time When Hypnotic Suggestibility is Controlled.
Eskridge, Veronica L.
This study was designed to investigate the effect of a placebo (sugar pill) accompanied by suggestions that the pill would either (1) improve performance as a stimulant or (2) cause a deterioration in performance as a depressant when the performance in question was the subjects' complex reaction time to a light stimulus. The Harvard Group Scale of Hypnotic Susceptibility (HGHS) was administered to 160 females enrolled in courses offered at the Department of Health and Physical Education for Women at Sam Houston State University during the fall semester of 1974 or the spring semester of 1975. Approximately equal members of physical education majors and other majors were tested. Thirty subjects scoring high hypnotic susceptibility and 30 subjects scoring low hypnotic susceptibility on the HGHS were located. Ten subjects of high hypnotic susceptibility were randomly assigned to each of the two experimental variables and the control group. The same assignment procedure was followed for the subjects of low hypnotic susceptibility. Individual pretests and posttests on complex reaction time were administered to each group. Analysis of the data indicated that no significant differences existed between any of the groups in question. (Author)
