Neuroticism is a personality trait associated with impaired attention, memory, and error detection. Thus, the present study investigated the visual N100 and P200 event-related potentials components associated with attention using a 2-back working memory task in healthy neurotic and nonneurotic participants, evaluated using the Neuroticism, Extraversion, Openness Five Factor Inventory. A total of 35 healthy participants were asked to perform the 2-back task while recording electroencephalographic activity from 64 electrodes on the scalp. Analysis of the N100 and P200 amplitude and latency in high neuroticism and low neuroticism subjects showed an increased P200 amplitude and latency for high neuroticism subjects in the frontal and parietal regions, respectively. However, there were no significant performance differences between the high and low neuroticism subjects for the 2-back working memory task. Therefore, the results suggest that neuroticism is associated with the P200 component elicited in the context of a working memory task.

神经质是一种与注意力、记忆力和错误检测能力受损相关的人格特征。因此，本研究在健康的神经质和非神经质参与者中使用 2-back 工作记忆任务调查了与注意力相关的视觉 N100 和 P200 事件相关电位成分，并使用神经质、外向性、开放性五因素量表进行评估。共有 35 名健康参与者被要求执行 2-back 任务，同时记录头皮上 64 个电极的脑电图活动。对高神经质和低神经质受试者的 N100 和 P200 振幅和潜伏期的分析显示，高神经质受试者在额叶和顶叶区域的 P200 振幅和潜伏期分别增加。然而，对于 2-back 工作记忆任务，高和低神经质受试者之间没有显着的表现差异。因此，结果表明神经质与在工作记忆任务的背景下引发的 P200 成分有关。
