A promising line of research on forensic assessment of paraphilic sexual interest focuses on behavioral measures of visual attention using sexual stimuli as distractors. The present study combined event-related potentials (ERPs) with behavioral measures to investigate whether detection of a hidden sexual preference can be improved with ERPs. Normal variants of sexual orientation were used for a proof-of-concept investigation. Accordingly, 40 heterosexual and 40 gay men participated in the study. Within each group, half of the participants were instructed to hide their sexual orientation. The results showed that a match between sexual orientation and stimulus delays responses and influences ERP before motor responses. Late ERP components showed higher potential in differentiating hidden sexual preferences than motor responses, thereby showing how ERPs can be used in combination with reaction time measures to potentially facilitate the detection of hidden sexual preferences.

关于性兴趣的法医评估的一项有前途的研究侧重于使用性刺激作为干扰物的视觉注意力的行为测量。本研究将事件相关电位 (ERPs) 与行为测量相结合，以调查是否可以通过 ERPs 改善对隐藏性偏好的检测。性取向的正常变体被用于概念验证调查。因此，40 名异性恋和 40 名男同性恋者参与了这项研究。在每组中，一半的参与者被指示隐藏他们的性取向。结果表明，性取向和刺激之间的匹配会延迟反应并在运动反应之前影响 ERP。晚期 ERP 成分在区分隐藏的性偏好方面显示出比运动反应更高的潜力，
