A recent advance in event-related potential (ERP) research indicates that the potential is a useful tool to investigate cognitive information processing in man. In a series of experiments, using the ERP measures, we attempted investigating the psychological problems on attention and performance. Main findings were :1. Information selection in an auditory attentional system : The attention-related negativity (or the Nd wave) showed the interaction between processes of between- and within-channel selection. This suggests that the selection processes share the limited attentional capacity for operations rechecking outcomes of a preattentive targetclassification stage.2. Effects of eye position on selective listening : The amplitude of Nd was enhanced when looking toward task-relevant tones, compared with looking toward irrelevant tones, indicating the influence of eye position on the auditory attentional system. In addition, tile Nd was observed for the first tone in each train immediately after attentional switching when looking toward the relevant tones, reflecting a role of eye position as spatial guidance.3. Visual selective attention : The C2 component of visual-evoked potentials for patterned stimuli, that were presented briefly in random order to upper and lower visual fields, was enhanced when the stimuli were attended. The enhancing effect of spatial attention on the evoked pattern-specific C2 component suggests an attentional mechanism of early sensory gating.4. Face recognition : For familiar faces, the negative slow ERP wave recorded during a face recognition task was larger over the left parietal (Wernicke's) area when compared to its right hemisphere homologue. In addition, the gradual development of ERP lateralization with the repetition of unfamiliar faces was observed. These findings suggest that verbal information attached to faces serves as effective cues in discriminating faces.

事件相关电位（ERP）研究的最新进展表明，电位是研究人类认知信息处理的有用工具。在一系列实验中，我们尝试使用 ERP 测量来研究注意力和表现方面的心理问题。主要发现是：1。听觉注意系统中的信息选择：与注意相关的负性（或 Nd 波）显示了通道间和通道内选择过程之间的相互作用。这表明选择过程对于重新检查预注意目标分类阶段的结果的操作共享有限的注意力能力。2．眼睛位置对选择性听力的影响：与看向任务相关的音调相比，看向不相关的音调时，Nd 的幅度增强，表明眼睛位置对听觉注意系统的影响。此外，在注意切换后，当看向相关音调时，在每个列车中的第一个音调中立即观察到瓦片Nd，反映了眼睛位置作为空间引导的作用。3．视觉选择性注意：图案刺激的视觉诱发电位的 C2 分量以随机顺序短暂呈现到上视野和下视野，当刺激被注意时会增强。空间注意对诱发模式特异性C2成分的增强作用提示了早期感觉门控的注​​意机制。4．面部识别：对于熟悉的面孔，在面部识别任务期间记录的负慢 ERP 波在左顶叶（韦尼克区）区域比其右半球同源区域更大。此外，还观察到随着陌生面孔的重复出现，ERP 偏侧化逐渐发展。这些发现表明，面部所附加的言语信息可以作为区分面部的有效线索。
