An Experience-dependent Aspect of Human Visual Acuity
Visual acuity tests were conducted using letters arranged in horizontal or vertical arrays. A significantly higher error rate was found for column arrangements. This effect was not evident when acuities were determined for Landolt ring targets or, with another group of subjects, for Chinese characters. Furthermore, children who knew the alphabet but did not yet read showed no effect. These results are consistent with the notion that visual experience may influence the development of visual resolution.
