Recent models of altruism point out the success of a strategy called 'Raise-The-Stakes' (RTS) in situations allowing variability in cooperation.
In theory, RTS is difficult to exploit because it begins with a small investment in an iterated Prisoner's Dilemma Game (PDG).
The second-to-fourth digit ratio (2D:4D) and mental rotation (MR) ability are sexually dimorphic traits that appear early in development and have been correlated with exposure to prenatal androgens (Grimshaw, Sitarenios, & Finegan, 1995; Lutchmaya, Baron-Cohen, Raggatt, Knickmeyer, & Manning, 2004).
The current study examined how 2D:4D and MR differences among women of European descent (N=41) were related to their (a) preferences for male faces: attractive (ATM), short-term (STM), and long-term mate (LTM), and (b) psychological femininity and masculinity, as measured by the Bem Sex-Role Inventory (BSRI) (Bem, 1981).
The implication is that symmetrical designs might provide an additional way to enhance physical attractiveness.
To find out, we conducted three experiments, two with human faces and one with abstract or nonrepresentational designs.
These results are discussed within the larger context of the applicability of evolutionary theory to the AIDS pandemic.An alternative explanation is that, due to a strong natural selection for sexual gratification, individuals evoke the evolved trait of self-deception to continue practicing high-risk sexual behavior.This alternative is tested using survey data from an Ariaal community in Marsabit District, northern Kenya.When compared with women with high 2D:4D ratios, low 2D:4D women (e) preferred a more masculine LTM, (f) recalled less parental bonding, (g) had shorter intimate relationships, and (h) reported more menstrual irregularity.The results are interpreted as support for an interactive hormonal theory of physical attraction.
