Digit Ratio Predicts Sense of Direction in Women
The relative length of the second-to-fourth digits (2D:4D) has been linked with prenatal androgen in humans. The 2D:4D is sexually dimorphic, with lower values in males than females, and appears to correlate with diverse measures of behavior. However, the relationship between digit ratio and cognition, and spatial cognition in particular, has produced mixed results. In the present study, we hyp...
متن کاملDigit Ratio Predicts Spatial Memory Performance in Women
The ratio of the length of the 2nd and 4th digits of the hand is an indicator of prenatal testosterone exposure and has been shown to be a within sex correlate of various abilities, such as visuo-spatial processing in men. However, a number of studies report such links also exist in women, whilst others show no link for either sex. Using a unique paradigm that sub-divides visuo-spatial processi...
متن کامل2D:4D Digit Ratio Predicts Delay of Gratification in Preschoolers
We replicate the Stanford marshmallow experiment with a sample of 141 preschoolers and find a correlation between lack of self-control and 2D:4D digit ratio. Children with low 2D:4D digit ratio are less likely to delay gratification. Low 2D:4D digit ratio may indicate high fetal testosterone. If this hypothesis is true, our finding means high fetal testosterone children are less likely to delay...
متن کاملHigher second fourth digit ratio predicts higher incidence of prostate cancer in prostate biopsy.
OBJECTIVES To analyze the validity of the ratio between the second and fourth finger (digit ratio; 2D/4D) of the left hand as a predictor for prostate cancer (PCa) in a group of men undergoing prostate biopsy. METHODS We prospectively recruited 204 consecutive patients referred for transrectal prostate biopsy due to PSA elevation or abnormal digital rectal examination between January 2008 and...
متن کاملLow digit ratio predicts early age at menarche in Colombian schoolgirls.
BACKGROUND The ratio between the lengths of the second and fourth fingers (digit ratio: 2D : 4D), a purported negative correlate of prenatal androgen exposure, has been inversely related to age at menarche. However, a recent study found high digit ratios in carriers of a single variant in the LIN28B gene, which has been linked to delayed menarche. METHODS We investigated the association of di...
