This study sought to test predictions made from disregulation and systems theories regarding self-deception and pain responsivity. Sixty-four subjects completed the L-scale of the Eysenck Personality Inventory and, based on their scores, were categorized as either High, Medium, or Low Deceptors. Both sensory threshold and three levels of affective pain judgments were determined using electrocutaneous nociceptive stimulation applied to the forearm. Results indicated that there were no differences among groups in their sensation thresholds. However, large differences in affective pain judgments emerged between High and Low Deceptors. High Deceptors differed significantly from Low Deceptors at the Tolerance (9.4 vs. 5.2 mA, p less than 0.001), Pain threshold (7.9 vs. 3.8 mA, p less than 0.001), and Discomfort (4.4 vs. 2.2 mA, p less than 0.01) judgment levels. These findings are consistent with a systems model of pain perception and are discussed in terms of the role of pain in mediating the relationship between cognitive coping patterns and recovery from illness and surgery. A possible opiate-peptide hypothesis of repressive coping & disregulation of pain is proposed.
本研究旨在检验关于自我欺骗和疼痛反应性的失调理论及系统理论所做出的预测。64名受试者完成了艾森克人格问卷的L量表，并根据得分被分为高、中、低欺骗组。使用施加于前臂的皮肤电伤害性刺激来确定感觉阈值以及三种程度的情感性疼痛判断。结果表明，各组之间的感觉阈值没有差异。然而，高欺骗组和低欺骗组在情感性疼痛判断上出现了很大差异。高欺骗组在耐受（9.4毫安对5.2毫安，p小于0.001）、疼痛阈值（7.9毫安对3.8毫安，p小于0.001）和不适（4.4毫安对2.2毫安，p小于0.01）判断水平上与低欺骗组有显著差异。这些发现与疼痛感知的系统模型一致，并从疼痛在调节认知应对模式与疾病及手术康复之间关系中的作用方面进行了讨论。提出了一个关于压抑性应对与疼痛失调的阿片肽假说。
