Dilation of the pupils is an indicator of an observer's sexual interest in other people, but it remains unresolved whether this response is strengthened or diminished by sexually explicit material. To address this question, this study compared pupillary responses of heterosexual men and women to naked and dressed portraits of male and female adult film actors. Pupillary responses corresponded with observers' self-reported sexual orientation, such that dilation occurred during the viewing of opposite-sex people, but were comparable for naked and dressed targets. These findings indicate that pupillary responses provide a sex-specific measure, but are not sensitive to sexually explicit content.
瞳孔放大是观察者对他人产生性兴趣的一个指标，但尚不清楚这种反应是否会因色情内容而增强或减弱。为了解决这个问题，本研究比较了异性恋男性和女性对成年男女电影演员裸体和着装照片的瞳孔反应。瞳孔反应与观察者自我报告的性取向相符，即在观看异性时会出现瞳孔放大，但对裸体和着装目标的反应相当。这些发现表明，瞳孔反应提供了一种性别特异性的测量方法，但对色情内容不敏感。
