The timeline of word recognition and oculomotor control in reading

在之前的资助期间，我们通过同时记录眼球运动(EM)和事件相关电位(ERP)来调查涉及阅读过程的基本和有争议的问题。基于我们在方法论和理论上的成就，我们建议现在重点关注两个问题。首先，副中央凹信息的影响：是否存在基于意义的预览益处？这些影响是由黄斑旁视力的个体差异所介导的吗？第二，空间注意广度：副中凹词语的影响是否取决于加工固定词语的难度类型(知觉、词汇、语义/情绪)？注意分布的宽度是否作为中心凹加工负荷的函数而动态调节？对这些问题的回答将有助于改进阅读过程中眼球运动控制的模型，并将区分使用加工梯度和顺序注意转移的框架。

During the previous funding period, we Investigated elementary and controversial issues concerning the processes involved in reading by simultaneous recording of eye movements(EM) and event-related potenfials (ERP). Based on our methodological and theorefical achievements, we propose to now focus on two issues. First, the influence of parafoveal information: Is there a preview benefit based on meaning? Are these effects mediated by Individual differences in parafoveal visual acuity? Second, spatial attention span: Does the influence of parafoveal words depend on the type of difficulty (perceptual, lexical,semantic/emofional) to process the fixated word? Is the width of the attentional distribution dynamically regulated as a function of processing load at the fovea? Answers to these questions will help to refine models of oculomotor control during reading and will distinguish between frameworks employing processing gradients versus sequenfial attention shifts.
