"Excessive" viewing of visual sexual stimuli (VSS) is the most commonly reported hypersexual behavior problem and is especially amenable to laboratory study. A pattern of enhanced sexual cue responsiveness is expected in this sample if hypersexuality shares features of other addiction models. Participants (N=122) who either reported or denied problematic VSS use were presented with emotional, including explicit sexual, images while their evoked response potentials were recorded. An interaction of hypersexual problem group and the level of desire for sex with a partner predicted LPP amplitude. Specifically, those reporting problems regulating their VSS use who also reported higher sexual desire had lower LPP in response to VSS. This pattern appears different from substance addiction models. These are the first functional physiological data of persons reporting VSS regulation problems.
过度观看视觉性刺激（VSS）是最常被报告的性欲亢进行为问题，尤其适合进行实验室研究。如果性欲亢进与其他成瘾模型有共同特征，那么在这个样本中预计会出现性线索反应增强的模式。向122名参与者呈现包括露骨性行为图像在内的情绪化图像，同时记录他们的诱发反应电位，这些参与者要么报告有问题的VSS使用情况，要么否认有此类情况。性欲亢进问题组与对性伴侣的性欲水平之间的相互作用预测了晚期正电位（LPP）的振幅。具体而言，那些报告在VSS使用调节方面存在问题且性欲较高的人，对VSS的反应中LPP较低。这种模式似乎与物质成瘾模型不同。这些是关于报告VSS调节问题的人的首批功能性生理数据。
