Sources of rCBF Effects in Syntactic Comprehension

描述（由申请人提供）：拟议研究的目的是调查在句法加工研究中获得的rCBF效应的来源。本实验室和其他地方的先前研究已经记录了不同组的受试者在测试句子理解中句法加工的协议中rCBF的不同模式。本文提出的研究将确定这些不同的rCBF模式是否反映了不同主体群体在不同程度上使用的不同非语言过程，或者它们是否反映了特定句法操作本地化的真正差异。将被测试的假设有：1。先前发现的rCBF变化与句子理解中的句法处理相关，将被复制。2. 这些变化是由于不同组被试在执行句子理解任务时使用视觉心理图像和短期记忆的差异造成的。

DESCRIPTION (provided by applicant): The goal of the proposed research is to investigate the sources of rCBF effects obtained in studies of syntactic processing. Previous studies in this laboratory and elsewhere have documented different patterns of rCBF in different groups of subjects on protocols testing syntactic processing in sentence comprehension. The research proposed here will determine whether these different patterns of rCBF reflect different non-linguistic processes that are employed to different degrees by different groups of subjects, or whether they reflect true differences in the localization of particular syntactic operations. The hypotheses that will be tested are: 1. Previously identified variation in rCBF changes associated with syntactic processing in sentence comprehension will be replicated. 2. These changes are due to differences in the use of visual mental images and short-term memory in performing the sentence comprehension task in different groups of subjects.
