Left-Right Differences in Tachistoscopic Recognition: Directional Scanning or Cerebral Dominance?

Abstract

Although both single letters and groups of 3 letters are more readily identified when they appear in the right visual field, right visual-field superiority on the 2 tasks is not correlated. Single letters presented in mirror-image orientation are also better identified in the right visual field. These results suggest that hemispheric dominance is more important than directional scanning in determining left-right differences in the recognition of single-letter material.
