中文摘要：

副中央凹预视效应指当读者正注视某个词（即位于中央凹的词n）时，可以获得词n右侧词（即位于副中央凹词n＋1或词n＋2）的部分信息。在阅读过程中读者能否从副中央凹预视到信息，会直接影响他们的阅读效率。因此，探讨阅读过程中的副中央凹预视效应产生的条件、影响因素及机制，成为阅读心理学需要解决的基本问题之一。本文系统总结了中外文阅读过程中副中央凹预视效应的研究进展，包括副中央凹预视效应的研究范式，中外丈阅读过程中副中央凹预视的信息类型、不同类型信息预视加工的时间进程，以及空间上获得预视信息的范围。最后提出中文阅读过程中副中央凹预视研究需要解决的几个关键问题。

英文摘要：

Parafoveal preview effect refers to when readers are fixating on one word （parafoveal word n）, they can obtain some information from the words on the right of their fixation （parafoveal word n＋1 or word n＋2） at the same time. And those previewed information can influence the reading efficiency directly. Therefore, to explore the necessary conditions, the influencing factors and the mechanism of the parafoveal preview during reading has become a significant focus in Reading Psychology. This paper systematically reviews the prior researches on parafoveal preview effects in English and Chinese reading. It mainly contains the paradigm of parafoveal preview effects, what kind of information readers can obtain, the time course of lexcial processing, and the spatial extent of preview benefit. At last, this paper further discusses several critical problems of parafoveal preview effects to be resolved.
