摘要： N2pc与空间选择性注意密切相关, 反映了一种对当前任务相关刺激的注意分配过程。N2pc自我特性的研究主要涉及理论解释、测量方法、源定位以及影响因素等方面, 而其实验范式主要有视觉搜索和视觉短时记忆搜索两种范式。以N2pc为指标的研究主要分为与视觉空间注意相关的基础性研究和应用性扩展研究。今后N2pc的研究应该在不断深入细化自身特性研究、做好基础性研究的同时, 更多的向应用性扩展研究拓展。

Abstract: The N2pc component is closely associated with spatially selective attention and is known to reflect the deployment of spatial attention to task-relevant stimuli. Studies investigating the properties of N2pc mainly focused on, but not limited to, its theoretical explanations, methods of measurement, neural sources, and influencing factors. The experimental paradigms of N2pc primarily consist of visual search and visual short-term memory search. Studies using N2pc as a tool could be divided into two aspects. One was the basic studies that investigated the relevant processing of visual spatial attention. A second centered more on applied research, which was also closely related to the processing of visual spatial attention. The future N2pc studies should further investigate its properties and promote both basic and applied research.
