Metacontrast and Saccadic Suppression

In the report by E. Matin et al. "Metacontrast and Saccadic Suppression" (Science 178, 179-182, 13 Oct. 1972), there were several errors in the first two columns on page 180. These were the result of changes made by the editors after the authors had returned the galley proofs. 1) The size of each of the five squares in the fixation array was 6 minutes of arc by 6 minutes of arc (6' by 6' visual angle); it was not 1.8 by 1.8 m or 6 by 6 feet as printed. 2) The size of the slit beneath the target square was 2 minutes of arc (horizontal) by 30 minutes of arc (vertical); it was not 0.6 m by 9 m as printed.
