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.
