原发性精神病的低恐惧模型得到了实证研究结果的支持，例如在预期威胁性刺激时生理唤醒减弱。体细胞标记假说提出，身体状态的显着变化被处理为情况是好还是坏的信号，并指导个体避免潜在的不利后果。本研究旨在阐明减弱的生理唤醒在原发性精神病与惩罚威胁和没有惩罚潜力的情况下违反公平规范之间的关系中所起的作用。原发性精神病与在选择向他人提供不公平的金钱优惠之前皮肤电导反应减弱有关，无论是否可能受到惩罚。皮肤电导减弱介导了原发性精神病与不公平提议选择之间的关联，尤其是在无惩罚条件下。然而，在惩罚条件下，即使在控制了皮肤电导的大小之后，原发性精神病也显着预测了不公平提议的选择。在惩罚威胁下，身体反应对人际决策的影响可能很小。目前的结果表明，对违反社会规范的低恐惧解释是原发性精神病的一种，应该重新讨论。
The low-fear model of primary psychopathy has been supported by empirical findings such as attenuated physiological arousal in anticipation of threatening stimuli. The somatic marker hypothesis proposes that salient changes in the bodily state are processed as signals of whether a situation is good or bad and guide an individual to avoid potential adverse consequences. The present study aimed to elucidate the role that attenuated physiological arousal plays in the relationship between primary psychopathy and fairness norm violations both under the threat of punishment and under no potential for punishment. Primary psychopathy was associated with an attenuated skin conductance response prior to the choice of unfair monetary offers to another person, regardless of the potential for punishment. Attenuated skin conductance mediated the association between primary psychopathy and the choice of an unfair offer, especially in the no-punishment condition. However, in the punishment condition, primary psychopathy significantly predicted the choice of unfair offers even after controlling for the magnitude of skin conductance. The bodily response may have only a marginal effect on interpersonal decision-making under a threat of punishment. The present results suggest that the low-fear account of social norm violations as a function of primary psychopathy should be re-discussed.
