The 2D:4D ratio is a sexually dimorphic trait which is lower in males than in females. A low value of 2D:4D indicates a uterine environment high in testosterone and low in estrogen which is a characteristic of males. Smaller 2D:4D ratios have been associated with disorders that occur more frequently in males, such as autism and ADHD. In contrast, eating disorders and depression (disorders that occur more frequently in females) suggests larger 2D:4D ratios. The purpose of the study is to replicate and extend the findings of previous research concerning the relationship of masculinized and feminized digit ratio to the entities of psychopathology.
