Es geht dabei um diese Studie:
Previous research has documented shifts in women’s attractions to their romantic partner and to men other than their partner across the ovulation cycle, contingent on the degree to which her partner displays hypothesized indicators of high-fitness genes. The current study set out to replicate and extend this finding. Forty-one couples in which the woman was naturally cycling participated. Female partners reported their feelings of in-pair attraction and extra-pair attraction on two occasions, once on a low-fertility day of the cycle and once on a high-fertility day of the cycle just prior to ovulation. Ovulation was confirmed using luteinizing hormone tests. We collected two measures of male partner sexual attractiveness. First, the women in the study rated their partner’s sexual attractiveness. Second, we photographed the partners and had the photos independently rated for attractiveness. Shifts in women’s in-pair attractions across the cycle were significantly moderated by women’s ratings of partner sexual attractiveness, such that the less sexually attractive women rated their partner, the less in-pair attraction they reported at high fertility compared with low fertility (partial r = .37, pdir = .01). Shifts in women’s extra-pair attractions across the cycle were significantly moderated by third-party ratings of partner attractiveness, such that the less attractive the partner was, the more extra-pair attraction women reported at high relative to low fertility (partial r = −.33, pdir = .03). In line with previous findings, we found support for the hypothesis that the degree to which a woman’s romantic partner displays indicators of high-fitness genes affects women’s attractions to their own partner and other men at high fertility.
Aus der Diskussion in dieser Studie:
Five previous studies found that the extent to which a woman’s male partner displayed hypothesized cues of high-fitness genes interacted with the woman’s fertility status to predict her feelings of extra-pair attraction. We also found this pattern, but only when we examined third-party ratings of male partner attractiveness as moderators of cycle shifts in attraction. Two previous studies found that the extent to which a woman’s male partner displayed hypothesized cues of high-fitness genes interacted with the woman’s fertility status to predict her feelings of in-pair attraction. We also found this pattern, but only when we examined women’s assessments of their partner’s sexual attractiveness as the moderator of cycle shifts in attraction.
This study provides the first demonstration within the same study that both third-party assessments of a man’s qualities and assessments made by his partner predict systematic cycle shifts in women’s attractions. This indicates that third parties can objectively observe the cues of high-fitness genes that predict women’s cycle shifts. It is noteworthy that in this study women’s own assessments of their partner’s sexual attractiveness were more strongly related to cycle shifts in in-pair attraction, whereas third-party assessments were more strongly related to cycle shifts in extra-pair attraction
Interessant ist es dabei auch, die angenommen Zeichen für gute Gene:
These studies demonstrate that, on high-fertility days of the cycle relative to low-fertility days, women express an increased preference for hypothesized indicators of high-fitness genes, including
- muscularity ,
- masculine bodies ,
- sexually dimorphic height ,
- masculine facial features –,
- masculine voices –,
- socially dominant behavior  –,
- low levels of fluctuating asymmetry –.
Im wesentlichen auch alles Anzeichen von Genstabilität und von hohen Testosteron.
Frauen finden also an ihren fruchtbaren Tagen eher „klassische Männer“ und ansonsten weniger klassische Männer gut, es stört sie mehr, wenn ihre Partner an ihren fruchtbaren Tagen diesen Kriterien nicht entsprechen als an anderen Tagen.
Evolutionär ist es eben besonders an den fruchtbaren Tagen interessant, Männer mit guten Genen interessant zu finden, während an anderen Tagen der Versorger oder der beständigere Mann eben auch interessant ist. Am besten ist natürlich nach wie vor die Kombination von beidem.
In einem Interview zu ihrer Studie führen die Forscherinnen noch aus:
But an exercise that required the women to rate how close they felt to their men yielded dramatic results. As women mated to less sexually attractive men moved from their least fertile to most fertile period, their closeness scores dropped one point on a seven-point scale. Women mated to the most sexually attractive men, meanwhile, experienced the opposite effect. As these women moved from their least to most fertile period, their closeness scores rose by a point. „Women with the really good, stable guy felt more distant at high-fertility periods than low-fertility periods,“ Haselton said. „That isn’t the case with women who were mated to particularly sexually attractive men. The closeness of their relationships got a boost just prior to ovulation.“(…)
The researchers found that women mated to the less sexually attractive men were significantly more likely to find fault with their partners and, again, feel less close to their partners during the high-fertility period than the low-fertility period. Women who rated their mates as more sexually attractive, meanwhile, did not exhibit these changes and instead reported being more satisfied with their relationship at high fertility than at low fertility.
Aus meiner Sicht ein guter Grund dafür auch in einer Beziehung Anzeichen von „guten Genen“ darzustellen und insofern ein Argument für Game auch in einer Beziehung, zumindest, wenn man nicht eh schon über gutes Aussehen Punkte machen kann.
