Abstract

Two experiments conducted with two perceptual priming tasks (word root completion, word identification) and two semantic priming task (free association, preference judgment) on an amnesic patient with right basal ganglia impaired to explore the dissociation between perceptual priming and semantic priming tests. It was found that the patient impaired perceptual priming tests, but not semantic priming tests compared to the controls. The results suggested that neurological structures of perceptual priming but not semantic priming were located in the basal ganglia, and different types of priming might have different neurological locus.

Keywords: amnesic patient; right basal ganglia; perceptual priming; conceptual priming; dissociation; localization
