AN EVOLUTIONARY PERSPECTIVE ON THE INTERACTION OF AGE AND SEX DIFFERENCES IN SHORT-TERM SEXUAL STRATEGIES

Abstract

Buss and Schmitt's sexual strategies theory (1993) suggests that short-term mating represents a larger component of men's than women's mating strategies. Assuming this sex difference there is potential for conflict. Symons argued that, because men are more interested in copulation than women, this gives women greater power in establishing conditions (short- vs long-term) under which copulation takes place. The result is that the conflict in sexual strategies is resolved in favor of women's relatively greater interest in long-term sexual strategies. This research tested the hypothesis that across ages men would decrease in desire to employ short-term mating strategies in favor of long-term mating strategies. Specifically, in Study I, men and women in their teens, twenties, and thirties or older were given a measure of desire for a committed relationship. It was predicted that women, regardless of age, would score high on desire for a committed relationship. In contrast, teenage boys would score low on desire for a committed relationship while men in their thirties or older would score as high as the women. In Study II both sexes in their teens, twenties, and thirties or older were given measures of desire for promiscuous sex. It was predicted that the women, regardless of age, would score low on desire for promiscuous sex. In contrast, teenage boys would score high on desire for promiscuous sex while men in their thirties or older would score as low as the women. Support was found for both predictions.
