Men's sexually aggressive behavior potentially could relate to either physiological hyporeactivity or hyperreactivity, and these two different physiological profiles could be associated with different underlying causes of sexual aggression. Thus, measurement of physiological reactivity could provide insight into mechanisms relevant to the etiology of sexual aggression. The relationship between sexual aggression and physiological reactivity was investigated in 78 community men (38 sexually aggressive and 40 non-aggressive men). In a laboratory protocol, the men were exposed to neutral, negative-affect-inducing, and positive-affect-inducing stimuli. Men's salivary cortisol concentrations and electrodermal activity (EDA) were measured throughout the laboratory procedure. Sexually aggressive men demonstrated (1) lower overall cortisol levels and (2) lower EDA reactivity in some conditions as compared to non-aggressive men. Results of this study were consistent with the idea that men's sexual aggression is associated with physiological hyporeactivity, a physiological profile that has been found to be associated with externalizing behaviors and psychopathic traits.
男性的性侵犯行为可能与生理低反应性或高反应性有关，这两种不同的生理特征可能与性侵犯的不同潜在原因有关。因此，生理反应性的测量可以深入了解与性侵犯病因学相关的机制。本研究调查了 78 名社区男性（38 名性侵犯者和 40 名非侵犯者）的性侵犯行为与生理反应性之间的关系。在实验室方案中，男性接触中性、负性情绪诱导和正性情绪诱导刺激。在整个实验室过程中，测量了男性的唾液皮质醇浓度和皮肤电活动（EDA）。与非侵犯者相比，性侵犯者表现出（1）整体皮质醇水平较低，（2）某些情况下 EDA 反应较低。本研究的结果与以下观点一致，即男性的性侵犯与生理低反应性有关，这种生理特征与外化行为和精神病特质有关。
