Short- and Long-Term Relationship Orientation and 2D:4D Finger-Length Ratio

Abstract

Recent studies have shown that preferences for close relationships (Long-Term Relationship Orientation) are independent of preferences for various sexual partners (Short-Term Relationship Orientation). In the current studies, we hypothesized that Short-Term Relationship Orientation would be negatively related to 2D:4D finger-length ratio (i.e., the more masculine, the higher Short-Term Relationship Orientation). Study 1 found a negative relationship between Short-Term Relationship Orientation and right, but not left, hand 2D:4D among 91 male participants. Study 2 found a negative relationship between Short-Term Relationship Orientation and left, but not right, hand 2D:4D among 65 male participants, even after controlling for age, relationship status, social desirability, and sex drive. Female participants (n = 142) did not show this relationship in Study 2. This sex difference was discussed in terms of flexible female sexual strategies, which are supposed to be contingent on the local environment or menstrual cycle variations.

Emotional stability is related to 2D:4D and social desirability in women: Possible implications on subjective well-being and psychopathology

“…At the same time social desirability is negatively related to anxiety and depression and positively with global life satisfaction. However, we did not find a significant association between social desirability and 2D:4D, which coincide with previous reports that studied this association [36,37,63,64]. Social desirability is an additional predictor of the components of subjective well-being, along with personality traits [8].…”

Interpersonal attraction: In search of a theoretical Rosetta Stone.

“…In fact, it is plausible that most men, like most women, achieved the greatest reproductive success from pursuing long-term rather than short-term mating strategies. Consistent with this strategic pluralism analysis that casual sex was historically available only to a select subset of men, men who possess characteristics indicative of biological features such as healthy immune functioning (e.g., possessing a symmetrical face and body; Gangestad & Thornhill, 1997;Thornhill & Gangestad, 1994) and exposure to high levels of prenatal testosterone relative to estrogen (e.g., possessing a long ring finger relative to the index finger; Schwarz, Mustafíc, Hassebrauck, & Jörg, 2011) tend to be especially likely to pursue short-term mating opportunities (see Gangestad & Simpson, 2000).…”

Influência de indicadores de masculinização na atratividade e sexualidade humana

“…Uma característica tipicamente dimórfica e potencial indicador da organização dos andrógenos pré-natais e, consequentemente, de sua influência no desenvolvimento do cérebro humano, é a taxa digital 2D:4D (Schwarz et al, 2011), que alguns estudos da sociossexualidade utilizam (Charles & Alexander, 2011;Clark, 2004;Hönekopp, Voracek, & Manning, 2006a;Mellen, 1981 (Mellen, 1981).…”

“…Schwarz et al, 2011). Esta taxa compreende o comprimento do dedo indicador (2D) dividido pelo do dedo anular (4D).…”

“…Em relação aos indicadores de masculinização físicos, a análise estatística indicou que homens com taxa 2D:4D da mão direita mais feminina são mais irrestritos no comportamento sociossexual, no desejo sociossexual e na sociossexualidade total. Este achado é o contrário do encontrado na literatura(Hönekopp et al 2006a;Schwarz et al, 2011) e do previsto para este estudo. Entretanto, essa associação oposta também foi encontrada porPutz et al (2004).Associação similar também foi encontrada para indicadores psicológicos.…”
