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.

本研究计划由三部分组成。第一部分提出的实验解决的问题是，意图是否以任务集的形式在与识别单词相关的直接处理（亚词汇、词汇和语义）中起作用，或者意图是否仅在使用这些处理的产物（如指导反应）中起作用，或者意图是否在两个层面都涉及。调查的一个相关部分是确定这种意图是不变的，还是随上下文而变化。第二部分提出了一系列的实验，试图确定空间注意力（不同于眼球运动）在视觉单词识别的早期过程中发挥作用的程度，并进一步确定其在特定领域处理中的参与程度。的最后一部分提出了实现版本的工作由现有的计算模型的视觉词识别和修改它,从我的实验室模拟一系列的基准测试结果,同时,提供一个新颖的思维方式如何(词频)是一个主要心理语言学因素代表精神,以及这个因素的影响(以及重复的密切相关的因素)大声朗读单个词时随时间展开。
