Evolutionary Psychology 5(4): 815-828Abstract
Two studies (total N = 689) tested the assumption of DeSteno, Bartlett, Braverman, and Salovey (2002) that sex differences in jealousy predicted by the evolutionary view are an artifact of measurement because they are restricted to a forced- choice response format and do not emerge when using continuous jealousy ratings. In Study 1, men and women rated how much a mate’s emotional and sexual infidelity contributed to their jealousy feeling. In Study 2, men and women rated the intensity of their jealousy feeling elicited by a mate’s emotional and sexual infidelity. In one condition they were asked to make their ratings spontaneously whereas in the other condition they were instructed to make their ratings only after careful consideration. The results of both studies lend no support for the artifact-of-measurement assumption. The implications of the present finding for the assumption of DeSteno et al. (2002) are discussed.
