Tracking Passive Sentence Comprehension in Agrammatic Aphasia.
People with agrammatic aphasia often experience greater difficulty comprehending passive compared to active sentences. The Trace Deletion Hypothesis (TDH; Grodzinsky, 2000) proposes that aphasic individuals cannot generate accurate syntactic representations of passive sentences and, hence, use an agent-first processing strategy which leads to at-chance performance. We tested this claim using th...
متن کاملBinding in agrammatic aphasia: Processing to comprehension.
BACKGROUND: Theories of comprehension deficits in Broca's aphasia have largely been based on the pattern of deficit found with movement constructions. However, some studies have found comprehension deficits with binding constructions, which do not involve movement. AIMS: This study investigates online processing and offline comprehension of binding constructions, such as reflexive (e.g., himse...
متن کاملSentence Comprehension in Aphasia
We show in this chapter that selective aphasic deficits dissociate distinct language processing systems. To this end, we focus on disruptions of lexical access that appear to implicate initial stages of sentence comprehension. The analyses we present turn on comparisons between agrammatic (Broca's) aphasic patients and paragrammatic (Wernicke's) aphasic patients. By the former we mean roughly, ...
متن کاملGrammatical comprehension deficits in non-fluent/agrammatic primary progressive aphasia.
IMPORTANCE Grammatical comprehension difficulty is an essential supporting feature of the non-fluent/agrammatic variant of primary progressive aphasia (naPPA), but well-controlled clinical measures of grammatical comprehension are unavailable. OBJECTIVE To develop a measure of grammatical comprehension and examine this comparatively in PPA variants and behavioural-variant frontotemporal degen...
متن کاملThe Neurobiology of Agrammatic Sentence Comprehension: A Lesion Study
Broca's area has long been implicated in sentence comprehension. Damage to this region is thought to be the central source of "agrammatic comprehension" in which performance is substantially worse (and near chance) on sentences with noncanonical word orders compared with canonical word order sentences (in English). This claim is supported by functional neuroimaging studies demonstrating greater...
