Investigating delayed parafoveal-on-foveal effects in eye movements during reading: The time course of word processing and its link to oculomotor control

在阅读的眼动研究领域中的两个主要计算模型（即，E-Z Reader和SWIFT）已经激发了大量翔实的实证研究。这些研究表明，例如，被认为是决定性的模型之间的旁丘脑对中央凹的影响是更复杂的性质比以前假设的，他们的经验不一致性可能是一个重要的指标，其时间结构。本研究的目的是：（1）建立这种新的延迟旁视-中央凹效应的边界条件，（2）研究中央凹和旁视词信息整合对眼跳程序时序的时间结构，以及（3）模拟关于注意分配的不同理论建议的数据，文字处理和阅读期间的扫视定时。实证研究结果将记录新的细节整合中央凹和旁视文字识别过程内的知觉广度在阅读。如何在模型中解释这一点将通过模拟来回答。与以往的做法不同，本提案旨在研究同一模型框架内的不同理论假设。还包括新的原则组合不纳入当前的阅读模型，其结果将有助于我们的理解之间的相互作用的处理和运动的时间在阅读的眼睛指导。

The two leading computational models in the field of eye-movement research on reading (i.e., E-Z Reader and SWIFT) have motivated a great deal of informative empirical studies. These studies suggest, for example, that parafoveal-on-foveal effects that were thought to be decisive between the models are more complex in their nature than previously assumed, and that their empirical inconsistency may be an important indicator for their temporal structure. In fact, they appear to be temporally delayed.The goals of the present research proposal are (1) to empirically establish the boundary conditions of this novel delayed parafoveal-on-foveal effect, (2) to investigate the temporal structure of integrating foveal and parafoveal word-information on the timing of saccade programs, and (3) to simulate the data with respect to different theoretical proposals on attention allocation, word processing, and saccadic timing during reading. The empirical findings will document new details on the integration of foveal and parafoveal word-recognition processes inside the perceptual span during reading. How this can be accounted for within the models will be answered with simulations. In contrast to previous approaches, the present proposal aims at studying different theoretical assumptions within the same model framework. Including also novel combinations of principles not incorporated in current reading models, the results will contribute much to our understanding of the interaction between processing and movement timing in eye guidance during reading.
