There is a large individual deviation for men, which may be caused by a difference in personality characteristics, in sexual interest in response to sexual stimuli. In this study, we investigate whether attention to the sexual region in a video depends on the personality characteristics of men, assessing this with an eye-tracking system. The study included 30 healthy males with a normal psychological state, who viewed a sexual video in which the sexual region had been designated. Visual attention was measured across the designated region according to gaze duration. Ten types of personality characteristics were evaluated as a T-score by a questionnaire. By Pearson's correlation coefficient, the relations between gaze duration at the sexual region and T-scores of paranoia, psychasthenia and social introversion were found to be statistically significant. By multivariate stepwise regression analysis, only social introversion was negatively associated with the sexual region. Even normal variation of personality characteristics can affect the viewing period of the sexual region. This is the first report showing that subjects with a high degree of paranoia, psychasthenia and particularly social introversion have a tendency to view the sexual region for a shorter duration.
男性的个体差异较大，这可能是由于个性特征、对性刺激的性兴趣不同所致。在这项研究中，我们使用眼动追踪系统评估了男性的个性特征是否会影响他们对视频中性区域的关注程度。该研究纳入了 30 名心理健康的男性，他们观看了一段指定了性区域的性视频。根据注视持续时间，在指定区域测量视觉注意力。通过问卷以 T 分数评估了 10 种个性特征。通过皮尔逊相关系数，发现注视性区域的时间与偏执、精神衰弱和社会内向的 T 分数之间存在统计学显著关系。通过多元逐步回归分析，只有社会内向与性区域呈负相关。即使是个性特征的正常变化也会影响对性区域的观看时间。这是首次报道表明，具有高度偏执、精神衰弱、特别是社会内向的个体观看性区域的时间更短。
