The broad objective of this project is to gain a more thorough understanding of word recognition processes. The investigator approaches this goal by investigating an often-ignored variable in language comprehension studies-namely, grammatical class membership. Recent research examining neurologically damaged populations reveals notable dissociations in the processing of nouns and verbs. Research by the investigator has extended the finding of a noun/verb contrast to an unimpaired population. These data indicate a greater left hemispheric involvement in the processing of verbs relative to nouns. The present proposal expands this study to investigate localization issues in the brain. Four experiments will be conducted. The first two represent experimental modifications, using different tasks and extending the investigation to the grammatical class categories of adjective and adverb. The last two experiments introduce a new methodology to test the claim of grammatical class organization in the brain. These experiments contrast the simultaneous and successive presentation of pairs of visually-presented stimuli to trace the origin of interference effects in comprehension across the lexical spectrum. The time course of activation for noun and verb stimuli will be explored by delaying input of one relative to the other. Investigations of grammatical category issues are critical to the refinement of psychologically and linguistically valid theories of word processing. The research contributes to this discussion by examing the interrelationship of lexical representations and processes in the brain. Its goal is to test recent claims made in the neuropsychological literature-namely, that there exist separate subsystems for the processing of nouns and verbs. If noun and verb locations are distinct, it is feasible that behavioral effects can be uncovered. The POWRE grant will provide the necessary funds for career advancement for the investigator. She is a non-tenure track Assistant Professor, a position she has held for the past five years. The grant will allow her to concentrate on her own research and delineate a long-term research program. It will also allow her to pursue a new methodological approach to the study of language processing. In turn, the pursuit of a new experimental technique and subsequent publication of the results could aid the investigator in obtaining a tenure-track position.

该项目的广泛目标是对单词识别过程有更透彻的了解。 研究人员通过研究语言理解研究中经常签名的变量来实现这一目标。 最近检查神经系统损害人群的研究揭示了名词和动词处理中的显着解离。 研究人员的研究扩大了与未损坏人群形成对比的名词/动词的发现。 这些数据表明，相对于名词，左半球的介入更大。 本提案扩大了这项研究，以研究大脑中的本地化问题。 将进行四个实验。 前两个代表实验修改，使用不同的任务并将研究扩展到形容词和副词的语法类别类别。 最后两个实验引入了一种新方法，以测试大脑中语法类组织的主张。 这些实验对比了观看式刺激对的同时和连续表示，以追踪整个词汇频谱理解中干涉效应的起源。 通过延迟一个相对于另一个的输入，将探索名词和动词刺激的激活时间过程。 语法类别问题的调查对于文字处理的心理和语言有效理论的完善至关重要。 该研究通过检查大脑中词汇表示和过程的相互关系来促进这一讨论。 它的目标是测试神经心理学文献中最新的主张，即存在单独的子系统来处理名词和动词。 如果名词和动词位置不同，则可以发现行为效应是可行的。 Powre Grant将为调查员提供必要的资金，以实现职业发展。 她是一位非终身助理助理教授，她在过去五年中担任过这个职位。 该赠款将使她能够专注于自己的研究并描述一项长期研究计划。 这也将使她能够采用一种新的方法学方法来研究语言处理。 反过来，追求一种新的实验技术和随后的结果发布可以帮助研究人员获得终身任期。
