Our investigation deals with high interindividual variability of Event-Related-Potentials (ERP). We tried to find out systematic causes of these variability. In a performance situation 36 Ss were asked to solve arithmetical tasks. They got a weak electric shock applied at one finger when the result was wrong (negative feedback), at another finger when it was correct (positive feedback). The electrical stimulus triggered the ERPs. Special personality characteristics related to "need-achievement" (processing of success and failure) "and anxiety" had influence upon ERPs. We found various differences between ERPs following positive as well as negative feedback (success and failure) that point to the suggestion that there exist differences in processing feedback information in persons with different personality traits mentioned above.
我们的研究涉及事件相关电位（ERP）的个体间高度变异性。我们试图找出这些变异性的系统性原因。在一个表现情境中，36名受试者被要求解决算术任务。当结果错误时（负面反馈），在一根手指上施加微弱电击；当结果正确时（正面反馈），在另一根手指上施加微弱电击。电刺激触发了ERP。与“成就需求”（成功和失败的处理）以及“焦虑”相关的特殊人格特征对ERP有影响。我们发现，正面反馈（成功）和负面反馈（失败）后的ERP存在各种差异，这表明上述不同人格特质的个体在处理反馈信息方面存在差异。
