OVERLAP AS A PREDICTOR OF FORM DISCRIMINATION UNDER SUPRATHRESHOLD CONDITIONS

Abstract

The purpose of this study is to investigate the relation between physical overlap and the discrimination of forms under suprathreshold conditions of viewing. The experiments reported include: determinations of reaction time required for correct discrimination of nonsense forms, similar determinations for the correct discrimination of ellipses, and an investigation of the influence of area on the discrimination of nonsense forms. An additional experimental procedure is introduced to ascertain whether overlap is a predictor of judged similarity. Computations are reported which relate the overlap hypothesis to search-recognition data for rectilinear form classes. Physical measures of overlap are positive in relation to performance measures in all cases. However, it is clear from the results of these experiments that form discrimination also involves factors other than overlap. (Author)
