In verification of an earlier study with a single S, the results of the present multi-S experiment indicated for tachistoscopic recognition of letters that the well-known superior performance of the right visual field over that of the left visual field consistently reduced across trials and eventually disappeared. The recently presented Shine combined analysis of variance permitted analysis of S-sources of variation. These sources reflected principally differential level of skill and differential hemispheric dominance across Ss.
