Detection thresholds for electrocutaneous stimulation were measured in young male subjects by two different methods - a method of limits and a forced-choice method - the latter assumed to be less influenced by decision processes. Relations between the threshold measures and scores in the EPI extraversion (E) and neuroticism (N) scales were studied. High N-low E ("unstable introvert") subjects had the lowest thresholds. The result is in line with the predictions made on the basis of Eysenck's personality theory.
通过两种不同方法——极限法和强制选择法——测量了年轻男性受试者的皮肤电刺激检测阈值，后者被认为受决策过程的影响较小。研究了阈值测量与艾森克人格问卷（EPI）外向性（E）和神经质（N）量表得分之间的关系。高N低E（“不稳定内向型”）受试者的阈值最低。该结果与基于艾森克人格理论所做的预测一致。
