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...
متن کاملDigit ratio, emotional intelligence and parenting styles predict female aggression
The contributions of digit ratio (2D:4D), emotional intelligence (EI) and parenting styles to social aggression were examined. Females (n = 215 emerging adults) completed 5 aggression measures, an EI measure, 2 parenting measures, and had their hands measured. Aggression correlated with each of the predictors. Left hand 2D:4D, EI, and parental authoritarianism resulted in the most robust model ...
متن کاملPrediction of hemispheric asymmetry as measured by handedness from digit length and 2D:4D digit ratio.
Hemispheric asymmetry is widely theorised as having a basis in prenatal androgen levels. However, these theories ignore a second round of asymmetrical changes in the brain, which occur at the same time as post-puberty surges in androgens. Hemispheric asymmetry in adults might therefore be explained in terms of the joint effects of prenatal and post-pubertal androgen levels. Evidence is emerging...
متن کاملDoes digit ratio (2D:4D) predict penile length?
Now advertized in at least one locale as the ‘sexy ratio’ with the caption, ‘Your hands give away your hotness’ (http://io9.com/ #!5794008; accessed 3 May 2011), an online summary of a recent study linking facial attractiveness to the ratio of the index and ring fingers indicates that digit ratio (2D:4D) research has reached mainstream culture. Digit ratio, most commonly the ratio of the index ...
