The Effect of Sophistication on Ratio- and Discriminative Scales

This is the authors' abstract. We don't add key points for this paper.

Stevens notes that modern efforts quantify subjective magnitudes have led three types of scales-all three designed show how sensation grows as a function of stimulus-values.1 Categoryand discriminative scales have generally been shown be nonlinearly related magnitude-scales. Are we, it has been asked, to be left with a purely operational view, accepting different psychophysical laws for different scaling-methods? Is there any way bridge the gaps between the different kinds of scales? In the face of discrepancies like this, it is not so much a question of which is correct, but how reconcile the differences. Until we do, we have not
