Sources of rCBF Effects in Syntactic Comprehension

描述（由申请人提供）：拟议研究的目标是调查句法加工研究中获得的rCBF效应的来源。在这个实验室和其他地方以前的研究记录了不同的模式，在不同的组的主题协议测试句法处理句子理解的rCBF。这里提出的研究将确定这些不同的模式的rCBF是否反映不同的非语言过程，采用不同程度的不同群体的主题，或者他们是否反映了真正的差异，在本地化的特定句法操作。将被测试的假设是：1。先前确定的变化rCBF的变化与句子理解中的句法处理将被复制。2.这些变化是由于在执行句子理解任务中，不同组的受试者在使用视觉心理图像和短期记忆方面存在差异。

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.
