Lexical competition effects in aphasia: deactivation of lexical candidates in spoken word processing
1Utrecht Institute of Linguistics OTS, Utrecht University, The Netherlands. Esther.Janse@let.uu.nl
Abstract:
Research has shown that Broca's and Wernicke's aphasic patients show different impairments in auditory lexical processing. The results of an experiment with form-overlapping primes showed an inhibitory effect of form-overlap for control adults and a weak inhibition trend for Broca's aphasic patients, but a facilitatory effect of form-overlap was found for Wernicke's aphasic participants. This suggests that Wernicke's aphasic patients are mainly impaired in suppression of once-activated word candidates and selection of one winning candidate, which may be related to their problems in auditory language comprehension.
