Abstract To increase internet traffic, some online media try to attract attention by presenting pictures that cover the sexual organs of the body. However, compared with naked pictures, it remains unclear whether these covered pictures can evoke similar levels of sexual arousal in heterosexual young adults and category-specific patterns in men. To examine the above problems, this research divided female and male pictures into 4 types (fully dressed pictures, naked pictures, covered pictures and underwear-wearing pictures). Behavioral experiments, eye-movement technology and ERP measurements were employed to explore the different levels of sexual arousal between men and women in response to pictures of different sexes and types. The results revealed that the level of sexual arousal induced by covered pictures was significantly higher than that induced by naked pictures. There was no significant difference in the P300 amplitude of the parietal lobe between covered pictures and naked pictures, but in the frontal lobe, the P300 amplitude induced by covered pictures was significantly higher than that induced by naked pictures. The results indicated that unlike the process of sexual arousal induced by naked pictures, the process of sexual arousal induced by covered pictures not only included the processing of visual stimuli but also required the frontal lobe to actively construct to perceive pictures of covered sexual organs as naked pictures and thus induce sexual arousal. In addition, we also found that both covered pictures (as reflected in the levels of sexual arousal and the average amplitude of P300) and naked pictures (as reflected in the levels of sexual arousal, the number of fixations and the average amplitude of P300) can induce category specificity in heterosexual men. On the one hand, this research extends knowledge regarding sexual cognition and finds that covered pictures can also evoke category specificity in men; on the other hand, from the perspective of brain cognition, the difference in sexual cognitive processing between covered pictures and naked pictures is recognized.

异性恋年轻人对覆盖性器官在线图片的反应和性别差异——基于行为、眼动和 ERP 的研究

摘要 为了增加网络流量,一些网络媒体试图通过展示覆盖身体性器官的图片来吸引注意力。然而,与裸照相比,这些被遮盖的照片是否能唤起异性恋年轻人的性唤起水平和男性的特定类别模式尚不清楚。针对上述问题,本研究将女性和男性图片分为4种类型(全装图片、裸照、遮盖图片和内衣穿着图片)。行为实验、眼动技术和 ERP 测量被用来探索男性和女性对不同性别和类型的图片的不同程度的性唤起。结果显示,遮盖照片诱发的性唤起水平明显高于裸照诱发的性唤起水平。覆盖图片与裸图的顶叶P300振幅无显着差异,但在额叶中,覆盖图片诱导的P300振幅显着高于裸图诱导的P300振幅。结果表明,与裸照诱发的性唤起过程不同,被遮盖的图片诱发的性唤起过程不仅包括对视觉刺激的处理,还需要额叶主动构建将遮盖性器官的图片感知为裸露。图片,从而诱发性唤起。此外,我们还发现,无论是覆盖图片(反映在性唤起水平和 P300 平均振幅上)还是裸照(反映在性唤起水平、注视次数和 P300 平均振幅上)都可以诱导类别异性恋男性的特异性。一方面,这项研究扩展了有关性认知的知识,并发现覆盖图片也可以唤起男性的类别特异性;另一方面,从大脑认知的角度,认识到覆盖图片和裸图在性认知处理上的差异。这项研究扩展了有关性认知的知识,并发现覆盖的图片也可以唤起男性的类别特异性;另一方面,从大脑认知的角度,认识到覆盖图片和裸图在性认知处理上的差异。这项研究扩展了有关性认知的知识,并发现覆盖的图片也可以唤起男性的类别特异性;另一方面,从大脑认知的角度,认识到覆盖图片和裸图在性认知处理上的差异。
