The Role of Breast Morphology in Women’s Rival Derogation Tactics

Abstract

Physical features that are desired by the opposite sex may drive competition between members of the same sex to gain access to potential mates. Women’s breasts are considered sexually attractive to men, and it has been shown that women may engage in competitive tactics to compete with or derogate women with ideal physical traits (i.e., physically attractive features). In the current online study, we investigated Hispanic women’s (n = 114) perceptions of breast stimuli that had been manipulated to display four levels of breast size (A-, B-, C-, and D-cup) and three levels of ptosis (i.e., levels of sagginess: non, low, and high) and their likelihood of engaging in rival derogation tactics, such as verbal and indirect aggression. The findings demonstrated that women were more likely to engage in rival derogation towards women with larger breast sizes. Women’s dispositional level of intrasexual competition did not play a role in rival derogation tactics. The results are in line with previous research suggesting that women’s rival derogation tactics are likely to be targeted towards women with attractive features that are desired by men.
