The detection of Chinese strokes and characters in visual noise

Abstract

This report discusses the effects of experience, method, and stimulus form on the detectability of dotted approximations to Chinese strokes and characters when they are masked by randomdot visual noise. The results of two experiments are interpreted to show that experience effects are nonexistent or small. Furthermore, even when small effects are present, they are in the direction opposite to that predicted. Similarly, method plays only a minor role in determining performance. However, strong stimulus-form effects exist that are well predicted by a previously developed autocorrelationâl-type computational model of the dotted form detection process.
