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.

这项研究计划由三部分组成。第一部分提出了实验，以解决以下问题：任务集形式的意图是否在与识别单词相关的即时加工(亚词汇、词汇和语义)中发挥作用，或者意图是否只在使用这种加工的产物(如指导反应)时起作用，或者意图是否在这两个水平上都涉及。调查的一个相关部分是确定这种意图是恒定的，还是随背景而变化的。第二部分提出了一系列实验，试图确定空间注意(与眼动不同)在视觉单词识别的早期加工中的作用程度，并进一步确定其在领域特定加工中的参与程度。拟议工作的最后部分包括实现现有视觉单词识别计算模型的一个版本，并对其进行修改，以模拟我实验室的一系列基准结果，同时，提供一种新的方式来思考一个主要的心理语言因素(词频)是如何在心理上表现出来的，以及当大声朗读单个单词时，这个因素(以及密切相关的重复因素)的影响是如何随着时间的推移而展开的。
