Abstract
This note evaluates the conclusion of Ayres (1966) that the evidence of Harcum, Hartman, and Smith (1963) for a perceptual scanning mechanism was produced by certain experimental artifacts. The conclusion is that the proposition of experimental artifact is not justified by the data which Ayres presented.
