Sex Hormones, particularly fetal testosterone, have been linked to the development of cerebral laterality and sex-specific cognitive capacities. A putative marker of fetal testosterone exposure, ratio of the second to fourth (2D:4D) finger, has been associated with elements of right hemisphere capacity but few studies have directly examined different abilities concurrently. The present study examined 2D:4D finger length ratio in relation to a two-part visuospatial judgment task and facial emotion recognition task. The findings showed that emotion perception was associated with both hemispheric dominance and 2D:4D finger length ratio in that directional asymmetries favoring the right hemisphere was observed for more feminine 2D:4D patterns whereas masculine 2D:4D demonstrated the opposite association. Visuospatial judgment was not associated with 2D:4D. In contrast to the oversimplified notion that spatial and social perception is specific to one or the other hemisphere, the current...
