The purpose of this research was to test the hypothesis that when an individual's romantic partner is sexually unfaithful the individual will be more angry with and aggressive toward the partner than the third party. 40 college men and women participated in this study. Each subject rated how angry and aggressive he or she would be toward him- or herself, the partner, and the third party if the partner were unfaithful. Intensity of love, degree of commitment, and mode of anger/aggression expression were also investigated. Support was found for the hypothesis.
