Self-focused attention and the placebo effect: Fooling some of the people some of the time

Abstract An experiment tested the hypothesis that mirror-induced self-awareness would minimize a “placebo” effect. Some subjects were led to believe that a drug that they were about to ingest would produce arousal symptoms as a side effect. Self-aware subjects in this condition subsequently reported experiencing less arousal from the placebo, and fewer of the side effects ascribed to it, than did less self-aware subjects. Discussion centered on the implications of these findings for placebo research and implications for two common alternative interpretations of self-awareness effects.
