Analysis of Superiority of the Right Visual Field in Bilateral Tachistoscopic Word-Recognition

Abstract

McKeever and Huling questioned procedures in experiments on lateral differences in the recognition of horizontally oriented multi-letter stimuli, tachistoscopically exposed bilaterally. They effected three major changes in this method and found superior scores for material in the right than left visual field, a result in the opposite direction of prior findings. Ideas from directional scanning and cerebral dominance accounts of lateral asymmetries suggest that McKeever and Huling's methodological innovations produced their result. Directional scanning notions indicate that horizontal targets impede measures of differences in processing skills of the cerebral hemispheres. These obstacles can be overcome by exposing vertically oriented targets.
