This report contains the results of an investigation of human capability to reproduce linear binary patterns presented tachistoscopically at inclinations in 15 steps from horizontal about the visual field. Eight-element targets of open and blackened circles were used, with four elements appearing on either side of fixation. The observers were required to reproduce the target patterns.nGenerally, fewer errors of pattern reproduction were found in the left visual field than in the right field. The greatest difference in number of errors on opposite sides of fixation appeared at about horizontal inclinations of the targets.
