| Abstract: | This study examined whether sex differences in jealousy would generalize to online infidelity. Based on the evolutionary psychological explanation for sex differences in jealousy (ancestral men's challenge of paternal uncertainty vs. ancestral women's challenge of ensuring paternal investment), we expected that men and women would perceive online infidelity similarly to conventional infidelity. The experimental design was a 2 (Infidelity Context: online or conventional) × 2 (Participant Sex) × 2 (Infidelity Type: emotional vs. sexual) mixed factorial. Participants were 332 (132 male, 200 female) undergraduates who completed a questionnaire assessing their responses to potential infidelity. As predicted, online and conventional infidelity elicited the same sex difference in jealousy. Implications for social scientists who study online behavior are discussed. |
