Studies in language comprehension have shown that readers interpret sentences word by word, rapidly integrating the meaning of each new word with the preceding context. With support from the National Science Foundation, Dr. Shelia Kennison will investigate the factors influencing how quickly skilled readers can integrate the meaning of individuals words within sentences. The research will test the hypothesis that semantic integration is carried out more rapidly for some words than for others. In the research, participants will read sentences while their eye movements are recorded. Eye movement recording is the most precise technique for measuring the processing difficulty experienced during reading. With this methodology, it is possible to measure the initial processing of a word separately from any reprocessing that may occur. The research will identify the characteristics of words that are associated with early (versus late) semantic integration. The research is important because it will broaden our knowledge of how readers coordinate multiple sources of information during comprehension, including syntactic, lexical, and semantic sources of information. The research will also add to our knowledge of the complex cognitive processing involved in perception, memory, and language. The broader impacts of the research include applications to the field of language disorders. By understanding how skilled, unimpaired readers integrate the meanings of words in sentences, researchers will be better able to identify individuals who carry out semantic processing abnormally. The research may also lead to a better understanding of the different ways language processing can be impaired and may contribute to the development of interventions designed to help impaired individuals increase their reading proficiency.

对语言理解的研究表明，读者逐字逐句地理解句子，迅速将每个新词的含义与前面的上下文结合起来。在美国国家科学基金会的支持下，Shelia Kennison博士将研究影响熟练读者如何快速整合句子中单个单词含义的因素。本研究将检验这一假设，即语义整合进行更迅速地为一些词比其他。在这项研究中，参与者将阅读句子，同时记录他们的眼球运动。 眼动记录是测量阅读过程中所经历的处理困难的最精确的技术。有了这种方法，就有可能测量一个词的初始处理与可能发生的任何再处理分开。这项研究将确定与早期（与晚期）语义整合相关的词的特征。 这项研究很重要，因为它将拓宽我们对读者在理解过程中如何协调多个信息源（包括句法、词汇和语义信息源）的了解。这项研究还将增加我们对感知、记忆和语言等复杂认知过程的了解。该研究的更广泛影响包括对语言障碍领域的应用。 通过了解熟练的、未受损的读者如何将单词的含义整合到句子中，研究人员将能够更好地识别出进行异常语义处理的个体。这项研究也可能导致更好地理解语言处理受损的不同方式，并可能有助于开发旨在帮助受损个体提高阅读能力的干预措施。
