The intentional object of romantic jealousy

Three studies tested the hypothesis derived from evolutionary psychological considerations of sex differences in the intentional object of romantic jealousy. In Studies 1 and 3, participants had to indicate in a forced choice whether their jealousy would be primarily directed towards the partner or the rival. In Study 2, participants rated separately the extent to which their jealousy would be primarily aimed at the partner and the rival. In Studies 1 and 2, the participants' answers referred to either a mate's actual emotional or sexual infidelity; in Study 3 they referred to suspected infidelity. As predicted, in each study, significantly more women than men reported that their jealousy would be primarily directed at the rival. Also, as predicted, these sex differences were especially pronounced when confronted with the adaptively primary infidelity type (i. e., male emotional and female sexual infidelity, respectively). Finally, Study 3 additionally showed that these sex differences are moderated by the participants' current relationship status and their own unfaithfulness. Limitations and implications of the findings are discussed. © 2008 Elsevier Inc. All rights reserved.
