Abstract
- Abstract: Prenatal testosterone exposure has been suggested to influence various personality traits including assertiveness/social dominance, aggressiveness, and impulsive sensation seeking (ImpSS). However, correlational work using 2D:4D digit ratio as an indicator for prenatal testosterone only converged on extremely small effects. Here we show that measuring traits with a high degree of specificity by combining extensive personality assessment, factor analysis with oblique rotation and subsequent partialling reveals an association between ImpSS and low 2D:4D (i.e. presumably high prenatal testosterone) in young healthy males. These findings suggest that prenatal testosterone exposure predicts ImpSS in men, that 2D:4D-personality associations are more specific than generally appreciated and that such associations can be more reliably detected using the approach to trait assessment described here.
