心理变态的双过程理论提出了导致这种疾病的不同病因机制：1）与情感-人际特征相关的防御（恐惧）反应的弱点，以及2）认知-执行功能受损，其特征是与冲动-反社会特征相关的大脑反应（如P3）减少。本研究探讨了精神病因素和皮质电反应的关系，以情绪和中性的图片在男性罪犯（N=139）使用精神病检查表修订版（PCL-R）进行评估。PCL-R（因子2）的冲动性反社会功能与早期P3脑反应的幅度降低的图片，无论效价，而情感人际维度（因子1）是专门与减少后期积极的潜在反应厌恶的图片。研究结果为双过程理论提供了进一步的支持，并增加了越来越多的证据，将精神病的冲动反社会方面与更广泛的外化倾向联系起来。研究结果进行了讨论，目前的举措，旨在将神经科学的概念纳入精神病理学分类。
The Two-Process theory of psychopathy posits distinct etiological mechanisms contribute to the disorder: 1) a weakness in defensive (fear) reactivity related to affective-interpersonal features, and 2) impaired cognitive-executive functioning, marked by reductions in brain responses such as P3, related to impulsive-antisocial features. The current study examined relations between psychopathy factors and electrocortical response to emotional and neutral pictures in male offenders (N=139) assessed using the Psychopathy Checklist-Revised (PCL-R). Impulsive-antisocial features of the PCL-R (Factor 2) were associated with reduced amplitude of earlier P3 brain response to pictures regardless of valence, whereas the affective-interpersonal dimension (Factor 1) was associated specifically with reductions in late positive potential response to aversive pictures. Findings provide further support for the Two-Process theory and add to a growing body of evidence linking the impulsive-antisocial facet of psychopathy to the broader construct of externalizing proneness. Findings are discussed in terms of current initiatives directed at incorporating neuroscientific concepts into psychopathology classification.
