Differential specialization of the cerebral hemispheres for the perception of sameness and difference

Abstract

The Johns Hopkins University, Baltimore, Maryland 21218 Pairs of letters were presented 4 deg left or right of fixation, and Ss were asked to indicate as quickly as possible whether the letters in a pair were the same or different. Reaction times for "different" responses were faster when stimuli were in the left visual field than in the right, but reaction times for "same" responses were faster when stimuli were in the right visual field than in the left. These results may indicate that the right hemisphere is better specialized for difference detection, while the left hemisphere is better specialized for sameness detection.
