Abstract

  The author investigated the implication of the frontal lobe in language comprehension using so-called pointing task (referring the task to choose and point to the proper object according to the presented word) and the sentence order task (referring the task to react according to the presented order by a sentence) , and the test of syntactic processing in aphasia. The results show as followings: 1. The deficit in the pointing task has relation to the lesion in the left middle frontal gyrus. The deficit in the pointing task due to frontal lobe damage might not be stemmed from the impairment of semantic process, but from the process in the way of choosing the objects according the target word. 2. The deficit in the sentence order task is closely related to the lesion in Brocaʼs area. The patients with frontal lobe lesion has impairment in this kind of task due to deficit of switching the view point when they face an unexpected sentence patterns.
