The Physioacoustic Method and the Creative Process

Abstract

This study investigated the physioacoustic chair's, i.e., an application of low-frequency sound waves, possible psychological effects with respect to deductive thinking and creativity as well as its possible effect on heart rate. Subjects, 21 men and 21 women, were randomly assigned in equal numbers to three groups: a control group, a placebo group, i.e., a group who believed that they underwent a physioacoustic treatment program which they however did not undergo, and a physioacousdc treatment group. After manipulation, subjects were required to take three psychological tests (measuring fluency and originality, preconscious thinking, and deductive thinking) in random order. During the entire experiment, subjects' heart rates were registered every minute. Analysis showed no significant differences among the groups with respect to psychological effects or to heart rate. The results were interpreted to mean that the physioacousdc chair provides a form of relaxation which does not produce effects on the creative process.
