Abstract
In two experiments, we used lateralized versions of the comparative judgment paradigm to investigate the effects of semantic congruity on hemispheric processing of symbolic information. When the comparative adjectives used in instructions were congruent with the scale end from which stimulus terms were drawn, reaction times were shorter when the hemisphere to which the terms were lateralized also controlled the hand used to register the response than when instructions and stimuli were semantically incongruent. These laterality-effect patterns suggest that hemispheric cooperation increases processing efficiency.
