阅读中的眼动控制理论与SWIFT模型

随着眼动研究的深入，近年来研究者受注意梯度指导理论影响，结合心理学的最新发展以及在相关实验研究的基础上提出了新的理论模型，其中最具代表性的是SWIFT模型。SWIFT模型遵循3条基本原则：（1）一定注意范围内的分布式词汇加工；（2）眼跳计划和目标选择的分离；（3）伴随中央凹目标抑制的眼跳机制。在构架上，该模型主要有两大功能模块：词汇加工和眼跳编程

Eyemovement Theories and SWIFT Model

With the development of eye movement,researchers have put forward some new models on the basis of many experiments,in which the SWIFT model is the most representative.These models are affected by the theory that is the guidance by attentional gradient.The SWIFT model has three principles:(1)lexical information processing is spatially distributed over an attentional window.(2)saccade timing is separated from saccade target selection.(3)saccade generation is an autonomous process with inhibition by foveal targets.The model has two parts:lexical processing and saccade programming.
