Digit ratio (2D: 4D) and social integration: An effect of prenatal sex hormones
The position people occupy in their social and professional networks is related to their social status and has strong effects on their access to social resources. While attainment of particular positions is driven by behavioral traits, many biological factors predispose individuals to certain behaviors and motivations. Prior work on exposure to fetal androgens (measured by second-to-fourth digi...
متن کاملSecond to fourth digit ratio and face shape.
The average human male face differs from the average female face in size and shape of the jaws, cheek-bones, lips, eyes and nose. It is possible that this dimorphism is determined by sex steroids such as testosterone (T) and oestrogen (E), and several studies on the perception of such characteristics have been based on this assumption, but those studies focussed mainly on the relationship of ma...
متن کاملDigit Ratio (2D:4D): A Biomarker for Prenatal Sex Steroids and Adult Sex Steroids in Challenge Situations
Digit ratio (2D:4D) denotes the relative length of the second and fourth digits. This ratio is considered to be a biomarker of the balance between fetal testosterone (T) and estrogen (E) in a narrow window of early ontogeny. Evidence for this assertion is derived from direct and indirect measures of prenatal hormonal exposure (in experimental animals, via amniotic fluid samples and in the study...
متن کاملDigit ratio links prenatal hormone exposure with adult lung function
0.94 ± 0.30 to female values of 0.961 ± 0.033.2 A separate study of adult male Han reported similar digit ratio values of 0.9478 ± 0.0322 for the right hand.3 Park and coworkers1 postulated that age may have had an effect on digit ratio, but if so, the effect must have been subtle since age was not significantly correlated with digit ratio in males or females in their study. Furthermore, the ut...
متن کاملSecond-to-fourth digit ratio and facial shape in boys: the lower the digit ratio, the more robust the face.
During human ontogeny, testosterone has powerful organizational and activational effects on the male organism. This has led to the hypothesis that the prenatal environment (as studied through the second-to-fourth digit ratio, 2D : 4D) is not only associated with robust adult male faces that are perceived as dominant and masculine, but also that there is an activational step during puberty. To t...
