Two “same-different” reaction time experiments, analogous in task demands made on the S, were designed to test laterality differences in. perception. Ten normal right-handed Ss performed a verbal task in which they decided whether or not two three-letter words belonged to the same conceptual class. Ten different Ss performed a spatial task in which they decided whether two 16-cell matrices with 3 blackened cells were identical. Reaction times were found to be sensitive to laterality differences in perception. Verbal stimuli were processed faster when presented in the right visual field, and thus projected directly to the left cerebral hemisphere; spatial stimuli were processed faster when presented in the left visual field, and thus projected directly to the right cerebral hemisphere. These results were analyzed in terms of implications regarding hemispheric asymmetries for processing of verbal and spatial material and the nature of interhemispheric transfer of information.

This paper is based upon a dissertation submitted by the author to the Psychology Department of Stanford University in partial fulfillment of the requirements for the degree of Doctor of Philosphy, “Hemispheric Specialization for the Processing of Visually Presented Verbal and Spatial Stimuli: A Reaction Time Analysis.” 1971.
I would like to thank my advisor. Dr. Charles R. Hamilton. for his helpful suggestions during all phases of this research. Thanks are also due to Sally P. Springer for being instrumental in first suggesting the possibilities of a reaction time analysis of hemispheric dominance (personal communication, 1969).
