title: Relation of the normal-deviate vision receiver operating characteristic curve slope to d'.
abstract: Past studies have shown that vision receiver operating characteristic curves plotted on normal-deviate coordinates fit straight lines for which the inverse of the slope is proportional to the index of detectability d'. This Communication offers a theoretical interpretation of that empirical relationship.
