Abstract
This study reports an investigation of 11 measures of pattern discriminability. These measures included 2 determinations of size thresholds; 4 measures of identification time under constant illumination and 1 under constantly increasing illumination; 2 measures of sorting performance; and 2 learning measures. The 11 measures were applied to a set of 16 arbitrarily selected forms. The hypothesis that differences would be found between measures of discriminability obtained in visibility and legibility tasks (i.e., between measures taken at or near threshold and at supra-threshold levels) appears to be substantiated.Keywords
