Automatic access to lexical semantics in aphasia: evidence from semantic and associative priming.
We report the auditory lexical decision performance of four patients, all of whom are clinically diagnosed as Broca's aphasics. In a task that separates associative from semantic priming, all four patients show significant priming effects and no interaction with type of relatedness. We find no evidence to support some of the current accounts of these patients' linguistic difficulties in terms of an impairment in automatic processing routines. Instead, we argue that automatic access to lexical semantics is intact.
