Linguistic Processing and Executive Control: Evidence for Inhibition in Broca’s Aphasia
نویسندگان
چکیده
We investigated the hypothesis that inhibition is impaired in a group of Broca’s aphasics relative to a group of language-unimpaired controls. We focused on distractor interference and spatial negative priming (NP) effects, which involve the ability to inhibit (i) distracting information and (ii) irrelevant information that exerts its effect from one trial to the next, respectively. The results reflect a distractor interference effect which is in line with suggestions that inhibition is impaired in aphasia. The robust NP effect in the aphasics is accounted for in terms of a deficit in processing information on a local (vs. global) level of analysis.

Neuropsychological Double Dissociation between Linguistic Levels: Clinical Linguistic Evidence from Iranian Aphasic Patients
Introduction: In this paper we report on clinical linguistic applications of several versions of the Bilingual Aphasia Test (BAT) and the Persian Aphasia Battery (PAB) developed to assess patterns of recovery and language impairments in monolingual and bilingual aphasics with different clinical histories living in Iran. Methods: The participants are adult monolingual native speakers of Persian ...
متن کاملFunctional Categories and Clause Structure in a Greek-English Speaking Bilingual Patient with Broca’s Aphasia: Evidence from Adverb Placement
Recently, types of language impairment associated with damage in Broca’s area have been the focus of an increasing number of cross-linguistic studies. There are at least two reasons for this. First, it has been observed that manifestations of Broca’s aphasia differ across languages, and thus the crosslinguistic evidence is crucial in order to understand better the nature of linguistic disorders...
متن کاملLexical competition eVects in aphasia: Deactivation of lexical candidates in spoken word processing
Research has shown that Broca’s and Wernicke’s aphasic patients show diVerent impairments in auditory lexical processing. The results of an experiment with form-overlapping primes showed an inhibitory eVect of form-overlap for control adults and a weak inhibition trend for Broca’s aphasic patients, but a facilitatory eVect of form-overlap was found for Wernicke’s aphasic participants. This sugg...
متن کاملSpeech production in Broca’s agrammatic aphasia: Syntactic Tree Pruning
Broca’s agrammatic aphasia entails a syntactic deficit both in sentence comprehension and in sentence production. This chapter describes the intriguing pattern of deficits in speech production, and shows that this type of inquiry interacts with linguistic theory as well as with knowledge about brain-language relations. The syntactic tree, a syntactic construct that has originally been suggested...
متن کاملBroca's aphasia is associated with a single pattern of comprehension performance: a reply.
Over many years now, we have provided evidence that the cortical area associated with Broca’s aphasia sustains operations necessary for the analysis of syntactic constructions that contain displaced constituents. A massive body of empirical data— from comprehension, real-time processing, and grammaticality judgment—shows that Broca’s area supports mechanisms involved in the computation of trans...
