Twenty-nine members of an undergraduate psychology class (15 men and 14 women) were administered the Schematizing Test, a test of leveling-sharpening. Of this group, 12 were myopic while 17 had normal (emmetropic) vision. The emmetropes made significantly larger errors in judging the mean increment of each Schematizing Test series than did the myopes. Point biserial correlations indicated a highly significant relationship between myopia and sharpening, especially for the females. Implications for the relationship of myopia and personality were discussed.
