Theoretical and empirical relationships among data matrices : difficulty, discrimination and similarity Tindall, Albert Douglas
Abstract
Theoretical and empirical relationships between paired comparison, PC, same-different choice times and perceived difficulty on a cartwheel task are investigated. An ordering of pairs of stimuli by the use of discrimination choice time predicts the subject's ordering of these pairs according to difficulty of discrimination. Two general models are developed to predict unilateral similarity proportions from PC response latencies. Though both models predict that unilateral similarity proportions are related to directional PC choices, only the ratio of differences model predicts the obtained standard stimulus effect.
