Jealousy and sex differences in response to hypothetical relationships developed via the Internet by participants' romantic partners were examined. Participants were 119 undergraduate students from a private Western university who participated on-campus, and 877 off-campus individuals who participated via computer. Participants responded to a questionnaire that described one's romantic partner engaging in an on-line relationship. The nature of the relationship, emotional or sexual, possibility of a partner meeting the rival, possible and impossible, and divestment of the partner's resources, low or high, were all varied. Conditions describing a rival with whom a meeting was possible, sexual on-line infidelity, and high divestment of resources elicited greater jealousy. Women reported greater jealousy than men when a partner's meeting with the rival was impossible. Results are discussed in terms of the evolutionary perspective of sex differences.
