  Abstract:
Digit ratio (2D:4D) is a biomarker for prenatal hormonal exposure. Some studies suggest that prenatal hormonal exposure might influence our cognitive styles characterized by systemizing and empathizing tendencies while other studies do not support these findings. By assessing 156 university students of engineering or mathematics (science, technology, engineering, and mathematics (STEM) (female: 63 and male 93) we concluded that digit ratio may support the hypothesis on sexual differences in cognitive styles.
