  • Title: Lexical competition effects in aphasia: deactivation of lexical candidates in spoken word processing.
    Author: Janse E.
    Journal: Brain Lang; 2006 Apr; 97(1):1-11. PubMed ID: 16099025.
    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.
