Eysenck's personality dimensions (neuroticism N, and extraversion, E) are formulated on the basis of levels of activity within the Central Nervous System. These can be explored by means of electroencephalographic techniques, such as the cerebral evoked potential (CEP). The augmenting-reducing construct allows the prediction of individual differences according to the tendency of subjects to augment or reduce sensory experience and CEP amplitude. The present work explores auditory CEP at increasing intensities in order to develop a stimulus-response function. A negative correlation between N score and the slope of the stimulus-response function for some CEP components was found. Together with the positive correlation between N score - CEP amplitude at minimum intensity, such data suggest a higher nervous system reactivity in subjects with high N score. For E dimension, a positive correlation between E score and latency of CEP components was found (inhibition effect). These findings support to some extent Eysenck's theory. The augmenting-reducing construct is discussed in terms of its contribution as a dynamic test of Eysenck's dimensions.
艾森克的人格维度（神经质N和外向性E）是根据中枢神经系统内的活动水平制定的。这些可以通过脑电图技术来探索，比如脑诱发电位（CEP）。增强-减弱结构允许根据受试者增强或减少感官体验及CEP振幅的倾向来预测个体差异。本研究探索了在强度增加时的听觉CEP，以便建立一个刺激-反应函数。发现某些CEP成分的N分数与刺激-反应函数的斜率之间存在负相关。再加上N分数与最小强度下的CEP振幅之间的正相关，这些数据表明高N分数受试者的神经系统反应性更高。对于E维度，发现E分数与CEP成分的潜伏期之间存在正相关（抑制效应）。这些发现一定程度上支持了艾森克的理论。从其作为对艾森克维度的动态测试的贡献方面讨论了增强-减弱结构。
