bjectives：The 2nd to 4th digit length(2D：4D) ratio reflects the amount of exposure and sensitivity to the prenatal sex hormone and it is considered to be the most convenient and useful way to understand the influence of sex hormone in the determination of human behavioral traits. This study was carried out to find the correlation between the 2D：4D ratio and characteristics of temperament and character in Korean university students. We assumed that 2D：4D ratio would show a strong correlation with temperament which is defined to be an inclination of an automatical emotional response to a stimulus.
Methods：Participants were 104 university students who completed 2 self-report measures：Temperament and Character Inventory(TCI), Temperament Test. We examined the 2D：4D ratio of each subject by measuring the lengths of the 2nd and 4th fingers using a photocopy measurement. We performed statistical analyses using correlation test and t-test to examine the relationship between 2D：4D ratio and psychological characteristics.
Results：We found out the typical sex difference in 2D：4D ratio. Women had significantly higher 2D：4D ratio than men. TCI-Character factor(TCI-C) didn’t show any significant correlation with the 2D：4D ratio. TCITempterament factor(TCI-T) and the item of Temperament Test showed a significant correlation with the 2D：4D ratio. In correlation analysis of the total group including all women and men, the 2D：4D ratio showed a significant positive correlation in a subscale(shyness with stranger) of harm avoidance scales in TCI-T. In correlation analysis of women’s group, the 2D：4D ratio showed a significant positive correlation in two subscales(fear of uncertainty) and[shyness to stranger] of harm avoidance scales in TCI-T. In correlation analysis of men’s group, the 2D：4D ratio showed a significant negative correlation with a sanguine temperament item bjectives：The 2nd to 4th digit length(2D：4D) ratio reflects the amount of exposure and sensitivity to the prenatal sex hormone and it is considered to be the most convenient and useful way to understand the influence of sex hormone in the determination of human behavioral traits.

Conclusion：The results suggest that the amount of exposure to sex hormone in the prenatal period seems to have an impact on the determination of temperament and characteristics.
