Classification of placebo drugs: effect of color.

Abstract

To study the role of color in the pscyhological effects of placebo drugs, 100 subjects were asked to place each of six different colored capsules into one of three classifications of drug effects. Results indicate that red and yellow placebos are classified as stimulants while blue placebos are classified as depressants.
