Mirth responses may be evoked in the laboratory and measured on the following functional levels: (1) the autonomic level by means of the psychogalvanometer; (2) the expressive action level by means of a motion-picture camera; (3) the level of immediate apperception by means of indeliberate verbal appraisals; and (4) the level of post-reflective apperception by means of deliberate verbal appraisals after an analysis of the presented material. Gentiles laughed more heartily at Jew-disparagement jokes than Jews did, in this experiment. Women estimated more highly than men the jokes on men, and vice versa. The experimenters concluded, "An unaffiliated object in a disparaging situation is a phrase which might be used to describe one type of accessory mirth-evoking thema--thema being proposed as a term to describe the dynamical constitution of a human situation."
