Abstract : The significance of the placebo effect on measures of drug-behavior interactions is discussed. By using a latin square design, g.i. motility measures were recorded during four experimental sessions each of which included periods of rest and of exposure to noise avoidance stress. Before each of three sessions Ss were given a placebo packaged in a distinctive capsule; one of the placebos was described as a tranquilizer, another as an energizer and the third as a placebo. No capsule was given prior to the fourth session. Analysis of the effects of these treatments is well under way. The general indications are that the various placebos produced effects consistent with the Ss' perceptions of their supposed psychoactive properties. (Author)
