中文摘要：

识别电位（Recognition Potential，RP）是被试看到可识别视觉刺激时，在200-250ms内达到峰值的脑电反应。识别电位的研究正处于理论探讨阶段，有两种主要观点用于解释RP。一种观点强调RP反映了视知觉分析成分：另一种观点强调RP反映了语义或概念加工成分。两种观点至今未达成一致。最近，针对两种观点质疑，研究者们提出了类别特征加工的观点，这一新观点在理论上符合大脑经济性的原则，具有一定的优越性，但尚需要更多的实证研究的支持。未来的RP研究应从实验材料的多样化、害研穷方法结合、娄别特征加工能力的习得机制等方面展开。

英文摘要：

Recognition potential is an electrical response of the brain peaking around 200 to 250ms after stimulus onset and obtained when subjects view recognizable stimuli （e.g. words, pictures）. The study of the RP is still under theoretical discussion. There are two views of the RP on what cognitive process it reflects. One view held the processing of visual information; the alternative one emphasized semantic or conceptual process. However, they have not reached an agreement yet. Recently, in order to compensate for the inadequacies of two views, researchers proposed that RP might reflect a processing of categorical features, which theoretically meets cognitive economy rules and has its own advantages. However, new hypotheses need to be further investigated. Great efforts should be made to RP research in terms of varies of materials, combination with other methods, learning mechanism of categorical feature processing.
