Jealousy in sexual and emotional infidelity: An alternative to the evolutionary explanation

Abstract

In an effort to make unequivocal the boundaries of infidelity, the present study used three infidelity scenarios (sexual infidelity, emotional infidelity, and the combination of sexual and emotional infidelity). Two other variables, gender of the participants and the extent to which they reported either few or several jealous tendencies, were included to generate a 3 × 2 × 2 independent groups design. Reactions of 317 undergraduate college students (165 women and 152 men) to the scenarios were assessed using both Smith and Ellsworth's (1985) six cognitive dimensions of emotion and a measure of emotional upset. A multivariate analysis of variance yielded significance for two of the main effects, the nature of the infidelity scenario and the gender of the participant. Univariate analyses indicated that women experienced more emotional distress over all of the conditions of infidelity, and, for women and men alike, conditions of infidelity involving a sexual component, whether alone or together with emotional infidelity, proved to be more upsetting than those involving only an emotional component.
