Verb Argument Structure Encoding during Verb Naming and Sentence Production in Normal and Agrammatic Aphasic Speakers: An Eyetracking Study Background and Rationale
Background and Rationale Individuals with agrammatic Broca’s aphasia have difficulty producing verbs and sentences (Menn & Obler, 1990; Miceli et al., 1984). This difficulty is associated with verb argument structure. Thompson (2003) proposed the Argument Structure Complexity Hypothesis (ASCH): verbs with more complex argument structure (as in 1 below) are more challenging to produce as compare...
متن کاملGrammatical Planning Units During Real-Time Sentence Production in Speakers With Agrammatic Aphasia and Healthy Speakers.
PURPOSE Grammatical encoding (GE) is impaired in agrammatic aphasia; however, the nature of such deficits remains unclear. We examined grammatical planning units during real-time sentence production in speakers with agrammatic aphasia and control speakers, testing two competing models of GE. We queried whether speakers with agrammatic aphasia produce sentences word by word without advanced plan...
متن کاملAgrammatic aphasia verb and argument patterns in Kiswahili-English spontaneous language.
BACKGROUND The spontaneous and narrative language of Kiswahili agrammatic aphasic and non-brain-damaged speakers was analysed. The bilingual participants were also tested in English to enable comparisons of verb production in the two languages. The significance of this study was to characterise bilingual Kiswahili-English spontaneous agrammatic output. This was done by describing Kiswahili-Engl...
متن کاملElectrophysiological responses to argument structure violations in healthy adults and individuals with agrammatic aphasia.
Sentence comprehension requires processing of argument structure information associated with verbs, i.e. the number and type of arguments that they select. Many individuals with agrammatic aphasia show impaired production of verbs with greater argument structure density. The extent to which these participants also show argument structure deficits during comprehension, however, is unclear. Some ...
متن کاملVerb and sentence production and comprehension in aphasia: Northwestern Assessment of Verbs and Sentences (NAVS).
BACKGROUND Verbs and sentences are often impaired in individuals with aphasia, and differential impairment patterns are associated with different types of aphasia. With currently available test batteries, however, it is challenging to provide a comprehensive profile of aphasic language impairments because they do not examine syntactically important properties of verbs and sentences. AIMS This...
