关于精神病态的临床和研究文献已经确定了一个情感悖论：精神病态者表现出正常的评估能力，但对情感线索的运用存在缺陷。作者使用R.D.黑尔（1991年）的《精神病态检查表修订版》和G.S.威尔士焦虑量表（1956年），确定了低焦虑的精神病态者和对照组，并检验了关于他们在词汇判断任务中表现的预测。结果支持了所有预测：（a）低焦虑的精神病态者对情感线索的评估与对照组一样好；（b）他们的词汇判断相对不受情感线索的影响；（c）他们的词汇判断相对不受情感中性的词频线索的影响；（d）他们的表现缺陷特定于涉及右手反应的条件。作者提出，反应调节不足可能是与低焦虑精神病态者相关的情感和认知缺陷的基础。
The clinical and research literatures on psychopathy have identified an emotion paradox: Psychopaths display normal appraisal but impaired use of emotion cues. Using R. D. Hare's (1991) Psychopathy Checklist-Revised and the G. S. Welsh Anxiety Scale (1956), the authors identified low-anxious psychopaths and controls and examined predictions concerning their performance on a lexical-decision task. Results supported all the predictions: (a) low-anxious psychopaths appraised emotion cues as well as controls; (b) their lexical decisions were relatively unaffected by emotion cues; (c) their lexical decisions were relatively unaffected by affectively neutral word-frequency cues; and (d) their performance deficits were specific to conditions involving right-handed responses. The authors propose that deficient response modulation may underlie both the emotional and cognitive deficits associated with low-anxious psychopaths.
