- Achim Schüzwohl, "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." - Piotr Sorokowski & Boguslaw Pawlowski, "Adaptive preferences for leg length in a potential partner":
"Here, we study how leg length influences attractiveness in men and women. Stimuli consisted of seven different pictures of a man and seven pictures of a woman in which the ratio between leg length and height was varied from the average phenotype by elongating and shortening the legs. One hundred men and 118 women were asked to assess the attractiveness of the silhouettes using a seven-point scale. We found that male and female pictures with shorter than average legs were perceived as less attractive by both sexes. Although longer legs appeared to be more attractive, this was true only for the slight (5%) leg length increase; excessively long legs decreased body attractiveness for both sexes." - Meghan P. Provost et al, "Short-term mating strategies and attraction to masculinity in point-light walkers":
"We investigated attraction to indicators of good genes (namely, masculinity as demonstrated by point-light walkers) in women varying in menstrual cycle status and sociosexual orientation. When women are fertile, they have the ability to gain genetic benefits from a male partner and should also be attracted to high levels of masculinity in men as a signal of genetic benefits. Sociosexual orientation is an individual difference that indicates openness to short-term mating and, thus, should influence aspects of mating strategy. Women with an unrestricted sociosexual orientation, as compared to women with a restricted sociosexual orientation, are more likely to engage in short-term relationships and obtain fewer nongenetic resources from their mates. Thus, they should place heavy emphasis on male masculinity as a sign of genetic benefits available from their mates." - Boguslaw Pawlowski & Grazyna Jasienska, "Women's body morphology and preferences for sexual partners' characteristics":
"Here we study female preferences for male resources, commitment, attractiveness, good sense of humor, and sensuality (when seeking both long-term and short-term partners) in relation to women's morphological traits such as height, weight, waist and hip girth, body mass index (BMI), and waist-to-hip ratio (WHR). We show that preferences for resources and attractiveness do indeed depend on women's phenotype."
