Bilateral vascular thalamic lesions are rare. Although a variety of neurobehavioral manifestations have been described, the literature is less documented with regard to accompanying linguistic disturbances. This article presents an in-depth neurolinguistic analysis of the language symptoms of a patient who incurred bilateral paramedian ischemic…

In this paper, we investigate the ability of Dutch agrammatic Broca's and Wernicke's aphasics to assign reference to possessive pronouns in elided VP constructions. The assumption is that the comprehension problems in these two populations have different sources that are revealed in distinct patterns of responses. The focus is primarily on the…

Behavioral variation in Broca's aphasia has been characterized as boundless, calling into question the validity of the syndrome-based schema and related diagnostic methods of acquired language disorders. More generally, this putative variability has cast serious doubts on the feasibility of localizing linguistic operations in cortex. We present a…

This study examines the comprehension patterns of various sentence types by Mandarin-speaking aphasic patients and evaluates the validity of the predictions from the Trace-Deletion Hypothesis (TDH) and the Double Dependency Hypothesis (DDH). Like English, the canonical word order in Mandarin is SVO, but the two languages differ in that the head…

Hierarchical models of agrammatism propose that sentence production deficits can be accounted for in terms of clausal syntactic structure [Friedmann, N., & Grodzinsky, Y. (1997). "Tense and agreement in agrammatic production: Pruning the syntactic tree." "Brain and Language, 56", 397-425; Hagiwara, H. (1995). "The breakdown of functional…

Provides redefinition for the syndrome of Broca's aphasia. Advances argument that the neurological explanation should be on separable psychological mechanisms that might be disrupted in isolation from other components of focal brain damages. Neuroanatomical implications are considered within the framework of a "strong localizationist" hypothesis.…

Compares writings of aphasic and deaf children. While sentences produced by both groups were of comparable length, aphasic children produced a more restricted range of sentence types. Structures requiring embedding were less frequent among aphasic children. It is hypothesized that, as noted in other tasks, aphasic children have difficulties with…

Individuals with agrammatic aphasia may have difficulty with verb production in comparison to nouns. Additionally, they may have greater difficulty producing verbs that have fewer semantic components (i.e., are semantically "light") compared to verbs that have greater semantic weight. A connectionist verb-production model proposed by Gordon and…

A hypothesis for the aphasic syndrome of aggramatism--the omission of function words and inflectional morphemes--is presented. The author tests and illustrates the efficacy of closely observing substantive universals of grammatical structure in proposing accounts of linguistic defects. (Author/MV)

This study reports intraindividual variations in the semantic and syntactic complexity of language and in the linguistic errors produced by mildly and moderately impaired adult aphasic subjects (N=10) in different communication contexts. Aphasic patients exhibited at least as many linguistic variations as controls in response to changing…

This study examined the nature of verb deficits in 14 individuals with probable Alzheimer's Disease (PrAD) and nine with agrammatic aphasia. Production was tested, controlling both semantic and syntactic features of verbs, using noun and verb naming, sentence completion, and narrative tasks. Noun and verb comprehension and a grammaticality…

In this paper, we investigate the performance of a Greek-English bilingual patient with Broca's aphasia and mild agrammatism on the placement of CP, MoodP, AspectP, and NegP-related adverbs, labeled specifier-type adverbs, and VP-related adverbs, labeled complement-type adverbs, by means of a constituent ordering task and a grammaticality judgment…

This article uses the example of aphasia to discuss to what extent and under what constraints neuropsychiatry borrows from linguistics. It is affirmed that genetic and functional, rather than static, structuralism is a useful tool for neuropsychiatry and that language functions can be seen to correspond to cerebral functions. (Text is in French.)…

The article proposes a reeducation program for conduction aphasics with reproductive difficulties. Program characteristics include analysis and manipulation of visual stimuli (written words and syllables), suppression of the compensation effect of the spared lexical-semantic system; and progressive increase in length and complexity of phonological…
