The effects of spontaneous and voluntary facial reactions on surprise and humor

Two investigations were conducted to determine the nature of the relationship between facial reactions and surprise and humor ratings as suggested by the facial feedback hypothesis. In the correlational investigation, individual subjects showed a positive correlation between their spontaneous facial reactions and funniness ratings over 36 cartoons (within subjects). Subjects who were facially more reactive to all the cartoons, however, did not rate them as funnier than did subjects who were less facially reactive (between subjects). In the experimental investigation, spontaneous facial reactions were evoked by a discrepant weight and also were inhibited or amplified on verbal demand. Surprise and funniness ratings varied with spontaneous facial reactions but were unaffected when those reactions were voluntarily inhibited or amplified. The results were interpreted as not supporting the facial feedback hypothesis and suggested that facial reactions may only correlate with emotional experience.These investigations were supported by Ball State University Research Grants.
