The relative lengths of the index and ring fingers (2D:4D), as well as the directional asymmetry betweenthe right and left hands [D(R–L)], are putative measures of prenatal sex hormone exposure. The 2D:4Dratio has been associated with a number of personality traits including neuroticism, agreeableness,extraversion, and openness to experience. The current study therefore aimed to build on these findingsby investigating 2D:4D in relation to Rotter’s (1966) Locus of Control Questionnaire (LoCQ). Significantpositive correlations were observed between LoCQ scores in females and right hand 2D:4D and D(R–L),though no such relationships emerged in males. The findings suggest that differences in concentrationand/or sensitivity to prenatal sex hormones may play a role in the development of an individual’s locusof control.
