2D4D, handedness and sexual orientation

<p>The project explores the associations between the second-to-fourth digit ratio (2D:4D) and individual characteristics such as handedness, sexual orientation, and sex differences. It aims to provide evidence for or against these associations through a large sample size and comprehensive analyses.</p>

<p>The dataset includes measurements of finger lengths and their ratios (2D:4D) obtained from 935 men and 900 women who participated in different experiments since 2010 to 2021. The dataset also incorporates data on handedness, sexual orientation, and demographic details like ethnicity.</p>

<p>Data were collected from Spanish and other European, South American, North African, and Middle Eastern participants. Measures include right and left-hand digit ratios for all the sample and handedness performance, self-reported handedness and self-reported sexual orientation (mesured with different procedures) for different subsamples.</p>
