"Visual Word Recognition: Intention, Attention, and Computational Modelling"

本研究计划由三部分组成。第一部分提出的实验，解决这个问题的意图的形式，任务集是否发挥了作用，在直接处理（词汇，词汇和语义）与确定一个词，或是否意图只发挥作用，在使用这种处理的产品（如直接响应），或是否意图参与这两个层次。调查的一个相关部分是确定这种意图是恒定不变的，还是随情况而变化。 第二部分提出了一系列的实验，旨在确定空间注意（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，并进一步确定其参与的程度，如果有的话，在特定领域的处理。 最后一部分的工作包括实现一个版本的现有计算模型的视觉单词识别和修改它，以模拟一系列基准结果从我的实验室，并在同一时间，提供一种新的方式来思考如何一个主要的心理语言因素（词频）是在心理上表现出来的，以及当阅读单个单词时，这个因素（沿着紧密相关的重复因素）的影响如何随着时间的推移而展开。

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.
