Agrammatism: Structural Deficits and Antecedent Processing Disruptions*
نویسندگان
چکیده
This chapter has three sections. The first provides an examination of the general notion that the brain distinguishes among amodal linguistic components. The second section attempts to support a more specific claim: Namely, that from a linguistic perspective, agrammatism can, best be reconstructed in syntactic terms. And the third section focuses upon processing disruptions in agrammatism-that is, upon the antecedents of the inability to represent structural information.

Sentence production in rehabilitation of agrammatism: A case study
Agrammatism is characterized by morphosyntactic deficits in production of sentences. Studies dealing with the treatment of these deficits are scarce and their results controversial. The present study describes the rehabilitation of a case diagnosed as chronic Broca's aphasia, with agrammatism, using a method directed to sentence structural deficits. The method aims to expand the grammatical rep...
متن کاملOn considerations of method and theory governing the use of clinical categories in neurolinguistics and cognitive neuropsychology: the case against agrammatism.
The pervasive use of clinical categories of aphasia in neurolinguistic and cognitive neuropsychological research reflects the assumption that these patient groupings represent disruptions of the normal language-processing system along theoretically significant lines. This premise is examined here with particular reference to the status of ‘agrammatism’. It is argued that there are compelling re...

Selective deficits in aphasics' grammatical production and comprehension are often cited as evidence that syntactic processing is modular and localizable in discrete areas of the brain (e.g., Grodzinsky, 2000). In this paper, we review a large body of experimental evidence suggesting that morphosyntactic deficits can be observed in a number of aphasic and neurologically intact populations. We p...
متن کاملLanguage deficits and the theory of syntax.
A new structural account of agrammatism is proposed, which analyzes the deficit in terms of one current theory of syntax. First, the motivation for accounts of this kind is given. Then, a variety of experimental findings from sentence comprehension in agrammatism are examined and accounted for in a unified way. It is shown that a minimal change in the syntactic model (achieved by imposing a spe...
متن کاملGrammatical Impairments in PPA.
BACKGROUND Grammatical impairments are commonly observed in the agrammatic subtype of primary progressive aphasia (PPA-G), whereas grammatical processing is relatively preserved in logopenic (PPA-L) and semantic (PPA-S) subtypes. AIMS We review research on grammatical deficits in PPA and associated neural mechanisms, with discussion focused on production and comprehension of four aspects of m...
