为方便读者理解近期发表的中文阅读词语加工和眼动控制整合模型(CRM),本文详细介绍该模型。模型包括词语加工和眼动控制模块。词语加工模块在交互激活框架基础上采纳了新的词切分假设:知觉广度范围内,汉字构成的所有词互相竞争并决出唯一胜者,当一个词被识别,它也同时被切分出来。眼动控制模块决定眼睛何时移动以及向何处移动,采用基于加工的假设。模型模拟了中文阅读与眼动控制的重要研究结果。模型着重解释了无词间空格时的词切分和眼跳目标选择等问题。

This paper is written in Chinese to help Chinese readers understand the recently published computational model of word processing and eye-movement control during Chinese reading,known as the Chinese Reading Model(CRM).The model consists of two modules:a word-processing module and an eye-movement control module.The word-processing module processes the information within the perceptual span.The module adopts an interactive activation framework and further introduces novel hypotheses regarding word segmentation.That is,all possible word candidates formed by the characters within the perceptual span compete for a single winner.Once a word is recognized,it is simultaneously segmented.The eye-movement control module uses the activation information from the word-processing module to decide when and where the eyes should move.It estimates how many Chinese characters can be processed in a single fixation and moves the eyes beyond these characters.The model successfully simulates important research findings in Chinese reading.It explains key issues,such as word segmentation and eye movement target selection when there are no explicit word boundary markers.
