摘要： 字词认知早期的N170成分是第一个对语言材料敏感的成分。最近对字词认知N170成分的研究主要集中在探讨其敏感性、偏侧化以及此成分的发展变化。大量研究认为字词N170成分的敏感性与正字法加工有关, 但也有一些研究认为其受语音、语义调制。对于此成分的偏侧化研究结果较一致认为是左侧化。最近的发展研究对N170成分进行探讨, 取得了一些成果。在剖析现有研究基础上, 本文认为应对字词认知N170成分的偏侧化、功能分离等问题进行深入研究。

Abstract: The N170 component is the first specific component in words processing. Recently, many studies focused on the sensitivity and lateralization of N170 component in visual words processing. This relatively specialized ERP component was believed to be associated with orthographic processing in many studies, while quite a few of studies reported that the N170 component was influenced by semantic and phonological processing. Moreover, the strong left-lateralized N170 response to visual words has been well demonstrated in ERP studies of the skilled alphabetic readers. Interestingly, many development studies of the N170 elicited by the alphabetic scripts were investigated the specialization of this component, and the studies of N170 component in different scripts were also important to understand the nature of words processing. Based on the review of the studies on N170 component, the researches may be addressed the diversified functions of it in future.
