This paper offers a preliminary examination of literature reviewing sex and gender differences in the five prototypic emotions of fear, anger, sadness, joy, and love. The paper notes that within the literature on sex and gender differences, the terms "sex" and "gender" are often erroneously referred to interchangeably ("sex" is a biological term while "gender" encompasses both biological sex and "cultural associates with being male and female"). Drawing on physiological and psychological research--much of which was conducted at universities using college students as subjects--the paper discusses similarities and differences between men and women in their emotional experiences. The paper discusses an interactive model of gender related behavior. Moreover, the paper addresses conceptual and measurement concerns involved in examining sex and gender. Though hardly exhaustive, the paper does indicate how women and men express themselves and how emotional experiences are affected by both physiological factors as well as associations with sex and gender roles.
