The Ratio of Second to Fourth Digit Length (2D:4D) in Children with Autistic Disorder
Introduction Emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of Autism spectrum disorders (ASD). The ratios of the lengths of the bones of the 2nd to the 4th digits (2D:4D) are purported to be markers for prenatal androgen exposure and to be established early in gestation. Ratio of second and fourth digits (2D:4D) is usually used as a proxy for prenatal t...

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...
متن کاملM.b. Wieling - Second-to-fourth Digit Ratio Related to Jealousy
The ratio of index finger length to ring finger length (2D:4D) is an index of prenatal androgen exposure. The larger the exposure to androgens, the smaller this ratio will be. Androgens “masculinise” people and may influence individual differences in a predictable way. In a study with 109 participants, 46 men and 63 women, the relationship between 2D:4D and jealousy was assessed. In a jealousy ...
