面部外观可以激发行为，并引发与奖励有关的大脑回路的激活。性别差异已被观察到的动机，以查看美丽的成人faces异性恋女性的动机是美丽的一般，而异性恋男性的动机，以查看异性美单独。虽然性别差异已观察到婴儿可爱的敏感性，婴儿的面孔似乎持有平等的激励显着性之间的男性和女性。本研究分别考察了成人和婴儿面孔中吸引力和可爱性的激励显著性。我们预测，考虑到其他观看选项，性别差异将出现的动机，以查看婴儿的面孔。异性恋参与者完成了按次付费的按键任务，这使他们能够控制刺激持续时间。性别差异被发现，婴儿举行更大的激励显着性的妇女，虽然两性区分婴儿面孔的可爱。在成人面孔中，男性比女性更努力地观察异性面孔。这些研究结果表明，与以往的报告相反，性别差异确实存在的婴儿面孔以及异性面孔的激励显着性。
Facial appearance can motivate behaviour and elicit activation of brain circuits putatively involved in reward. Gender differences have been observed for motivation to view beauty in adult facesheterosexual women are motivated by beauty in general, while heterosexual men are motivated to view opposite-sex beauty alone. Although gender differences have been observed in sensitivity to infant cuteness, infant faces appear to hold equal incentive salience among men and women. In the present study, we investigated the incentive salience of attractiveness and cuteness in adult and infant faces, respectively. We predicted that, given alternative viewing options, gender differences would emerge for motivation to view infant faces. Heterosexual participants completed a pay-per-view key-press task, which allowed them to control stimulus duration. Gender differences were found such that infants held greater incentive salience among women, although both sexes differentiated infant faces based on cuteness. Among adult faces, men exerted more effort than women to view opposite-sex faces. These findings suggest that, contrary to previous reports, gender differences do exist in the incentive salience of infant faces as well as opposite-sex faces.
