This program of research consists of three parts. The first part proposes experiments that address the issue of whether intention in the form of a task set plays a role in the immediate processing (sublexical, lexical and semantic) associated with identifying a word, or whether intention only plays a role in using the products of such processing (such as to direct a response) or whether intention is involved at both levels. A related part of the investigation is to determine whether such an intention is constant, or varies with the context. The second part proposes a series of experiments that seek to determine the extent to which spatial attention (as distinct from eye movements) plays a role in early processes involved in visual word recognition, and further, to determine the extent of its involvement, if any, in domain specific processing . The last part of the proposed work consists of implementing a version of an existing computational model of visual word recognition and modifying it so as to simulate a series of benchmark results from my lab, and at the same time, provide a novel way of thinking about how a major psycholinguistic factor (word frequency) is represented mentally, and how the effect of this factor (along with the closely related factor of repetition) unfolds over time when reading single words aloud.

该研究计划包括三个部分。第一部分提出的实验解决了以任务集的形式意图的问题，是否在与识别单词识别单词相关的即时处理（Sublexical，词汇和语义）中发挥作用，或者意图仅在使用此类处理的产物（例如直接指导一个响应）或是否涉及两个级别的意图。调查的相关部分是确定这种意图是恒定的还是随上下文而变化的。第二部分提出了一系列实验，试图确定空间注意力（与眼动不同）在视觉单词识别涉及的早期过程中起作用，并进一步确定其参与程度（如果有的话）在域特定的处理中。拟议工作的最后一部分包括实现视觉单词识别的现有计算模型的版本并修改它，以模拟我实验室的一系列基准结果，同时，提供了一种新颖的思考方式，可以思考主要的心理语言因素（单词频率）在精神上是如何代表了这种因素的影响，以及在重复的效果（与重复的效果上）如何过度读取。
