第二和第四个手指长度之间的比率（手指比例）是两性二态的，男性的数值较低。人们认为手指比例是产前睾酮暴露的标志，许多相关研究支持这一观点。在本研究中，我们调查了手指比例与一些已知显示男女得分差异的认知和性格测试之间的关系。在寻求感觉、精神病和神经质中发现了与预期方向相关的证据，所有这些都只适用于女性。数字比例和认知测试成绩之间没有关联。(C) 2002年Elsevier Science Ltd.出版
The ratio between second and fourth digit lengths (digit ratio) is known to be sexually dimorphic, with males having lower values. It is believed that digit ratio acts as a marker of pre-natal testosterone exposure and a number of studies of its correlates support this idea. In the present study, associations between digit ratio and a number of cognitive and personality tests which are known to show male-female score differences were investigated. Evidence for associations in the expected direction was found for sensation seeking, psychoticism and neuroticism, in all cases for females only. No association was found between digit ratio and cognitive test scores. (C) 2002 Published by Elsevier Science Ltd.
