Abstract

A new test of object decision in which a minimal view 2D silhouette of an object is presented together with 3 nonsense shapes has been administered to a consecutive series of patients with right and left hemisphere lesions. There was a significant deficit in the right hemisphere lesion group as compared with the left hemisphere group. It is concluded that this object decision test provides a measure of the integrity of pre-semantic perceptual processing systems.
