One area that has been extensively researched within the biological/evolutionary approach is that of human mating or sexual preferences. Buss (1994) studied attitudes and behaviours of men and women across 37 different cultures towards sexual behaviour. Buss found, for example, that compared to women, men are more interested in casual sex, prefer a younger partner and get more jealous over sexu...

Blast cells from 20 patients with acute leukemia (13 diagnosed myeloblastic and 7 as lymphoblastic, using the FAB classification) were studied using antibodies to lineage-specific differentiation markers. The phenotypic findings were usually consistent with the clinical diagnosis. However, examples were encountered where individual blast cells had a cytoplasmic marker of one lineage and a surfa...

The current research uses insights from evolutionary psychology and social cognition to explore the relationship between jealousy – both experimentally activated and chronically accessible – on men’s and women’s desire to start a family and invest in children. In our first two studies, primed infidelity threat led chronically jealous men and women to report a decreased interest in infants (Stud...

This exchange presents divergent views on a specific sex difference in jealousy. Everyone agrees that the sex difference in infidelity choice reported by Buss and his colleagues (Buss, Larsen, Westen, & Semmelroth, 1992) is replicable. However, we assert that individuals select a type of infidelity (sexual vs. emotional) as more distressing based on the perceived differential likelihood of each...

The present study aims to assess the validity and reliability of the Persian version of the Infidelity Questionnaire (INFQ). Specifically, INFQ assesses the possible elements of sexual and emotional infidelity. The instrument was translated through the back-translation strategy and revised by three panels. The validity and reliability of the INFQ were examined in the current study. Results show...

Two studies explored how domestic violence may be implicitly or explicitly sanctioned and reinforced in cultures where honor is a salient organizing theme. Three general predictions were supported: (a) female infidelity damages a man's reputation, particularly in honor cultures; (b) this reputation can be partially restored through the use of violence; and (c) women in honor cultures are expect...

CONTEXT Prior research has shown a strong correlation between HIV infection and a history of intimate partner violence, particularly among young women. However, the role violence plays in the sexual relationships of young people in Sub-Saharan Africa is not well understood. METHODS Locally trained interviewers conducted semi-structured interviews with 40 young men and 20 young women aged 16-2...

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 ...
