Previous research has demonstrated sex differences in face processing at both neural and behavioural levels. The present study examined the role of handedness and sexual orientation as mediators of this effect. We compared the performance of LH (left-handed) and RH (right-handed) heterosexual and homosexual male and female participants on a face recognition memory task. Our main findings were that homosexual males have better face recognition memory than both heterosexual males and homosexual women. We also demonstrate better face processing in women than in men. Finally, LH heterosexual participants had better face recognition than LH homosexual participants and also tended to be better than RH heterosexual participants. These findings are consistent with differences in the organisation and laterality of face-processing mechanisms as a function of sex, handedness, and sexual orientation.
先前的研究已经证明了在神经和行为层面上，面孔处理存在性别差异。本研究探讨了利手和性取向作为该效应的中介因素的作用。我们比较了 LH（左利手）和 RH（右利手）异性恋和同性恋男性和女性参与者在面孔识别记忆任务中的表现。我们的主要发现是，同性恋男性的面孔识别记忆比异性恋男性和同性恋女性都要好。我们还证明了女性的面孔处理能力优于男性。最后，LH 异性恋参与者的面孔识别能力优于 LH 同性恋参与者，而且也倾向于优于 RH 异性恋参与者。这些发现与面孔处理机制的组织和偏侧性随性别、利手和性取向的不同而存在差异的观点一致。
