Sources of rCBF Effects in Syntactic Comprehension

超出所提供的空间。本研究的目的是探讨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。以前发现的rCBF理解变异将被复制。2. 这些变化是由于执行句子理解的差异！（组织，城市，州）马萨诸塞州总医院，波士顿，马萨诸塞州萨金特学院，波士顿大学，波士顿，马萨诸塞州。请看第11页的说明。名称：David Caplan， m.d.， M.G.H.

EXCEED THE SPACE PROVIDED. The goal of the proposed research is to investigate the sources of rCBF effects obtained in studies of syntactlc 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 pattems 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 comprehension will be replicated. 2. These changes are due to differences in in performing the sentence comprehension !HI-OHMANGF ,511_'(_) (organtzatlon, city, state) Massachusetts General Hospital, Boston, MA Sargent College, Boston University,_ Boston, MA KEY PERSONNEL. <Gee instructions on Page 11.
