The averaged cortical evoked potential (CEP) was measured from 296 male subjects in two studies and was correlated with scores on intelligence and personality tests. For both studies, auditory stimuli were used with bipolar electrode placement to the Cz and T3 scalp positions. In the first study, with 84 subjects, stimulus intensity was 95 dB (all dB readings re 20 muN/m2). Intelligence was measured with the Mill Hill Vocabulary Scale and personality with H. J. Eysenck's PEN questionnaire. The second study, with 212 subjects, used additional stimuli at 75 dB and 55 dB. Intelligence was measured with the Ravens Progressive Matrices. State anxiety and other state measures at the time of testing were also taken. Neither study found any relation between the CEP and IQ or personality. However, more bored subjects showed larger CEP amplitudes. The results are discussed in terms of Ertl's neural efficiency hypothesis and Eysenck's arousal theory of personality.
在两项研究中，对296名男性受试者测量了平均皮层诱发电位（CEP），并将其与智力和人格测试得分进行关联。在这两项研究中，均使用听觉刺激，并将双极电极置于头皮的Cz和T3位置。在第一项研究中，有84名受试者，刺激强度为95分贝（所有分贝读数均相对于20微牛顿/平方米）。使用米尔希尔词汇量表测量智力，使用H. J. 艾森克的PEN问卷测量人格。第二项研究有212名受试者，使用了75分贝和55分贝的额外刺激。使用瑞文渐进矩阵测验测量智力。同时还记录了测试时的状态焦虑和其他状态指标。两项研究均未发现CEP与智商或人格之间存在任何关联。然而，较厌烦的受试者表现出更大的CEP波幅。将根据厄特尔的神经效率假说和艾森克的人格唤醒理论对结果进行讨论。
