MAGNITUDE ESTIMATION OF HEAVINESS AND LOUDNESS BY INDIVIDUAL SUBJECTS: A TEST OF A PROBABILISTIC RESPONSE THEORY 1

Abstract

One hundred magnitude estimates of heaviness were obtained for each of 18 weights from each of six S s and of loudness for each of 20 intensities from another six Ss. The stimuli were spaced at approximately equal logarithmic intervals. The mean magnitude functions of individual S s appear, in general, to deviate systematically from power functions. The distributions of responses, normalized by the mean response, appear to be skewed, highly peaked, and to have high tails. For at least half of the Ss, this response variability is no more than is needed to account for the errors in a simple two‐stimulus two‐response recognition experiment run under the same conditions. The data are examined in terms of a probabilistic response theory. Although the theory is clearly wrong in some of its details, certain of its qualitative features appear to be sustained.
