Visual Pattern Perception with Varied Fixation Locus and Response Recording

Abstract
10-element binary patterns of open and blackened circles were tachistoscopically exposed such that 0–10 of the elements appeared on the left of a fixation-cross. The specific orientation relative to fixation was unknown to O before exposure. O was required to reproduce the pattern of blackened circles on a blank template after each exposure. In each of three experiments a different arrangement of the template for recording responses was used. The usual tendency for greater accuracy for elements at the left was overcome when more than half of the elements had appeared to the left of the fixation-point. The form of response recording affected the results, which were accounted for in terms of visual sensitivity, implicit motor factors, and organizational factors in the memory system of O.
