“Agrammatism and Expressive Aphasia” All the articles reviewed and discussed in this paper observe the common topic of “agrammatism” and its role in researching individual cases of aphasia. Agrammatism is considered to be a variety of expressive aphasia that implies the inability to speak in a grammatically right manner. David Caplan (Montreal Neurological Institute), the author of “In defense of agrammatism” (1986), argues in his article that agrammatism can be approached in such a way that may cause it being a suitable type for aphasia examination, and that will eventually bring up a certain amount of remarkably exciting issues for study with regard to this particular type. In his research the author refers to Badecker’s and Caramazza’s study that “levied an attack upon the category of agrammatism as a coherent aphasic deficit”. He states that even though the mentioned authors may be right in some of their assumptions, that many accessible diagnostic categories of aphasiology are excessively wide and inadequately described in particular, their ideas exaggerate the essence of the phenomena, making too much of the case against more intently defined categories such as agrammatism. Referring to Shallice’s method of determining aphasic deficits named the “method of multiple dissociations”, Caplan proposes to put the similar techniques to use with the symptom of agrammatism, and to resolve such questions brought up as “whether the primary dissociations are adequate to delineate a syndrome” and “whether the secondary variation negates the existence of this putative broad syndrome”. Thoroughly researching Bedecker’s and Caramazza’s arguments about the essence of agrammatism, the author refuses to accept their rationales and conclusions. Caplan disproves their claims that the symptoms of agrammatism cannot be equally portrayed in each patient in terms of a single
