ABSTRACT
Having been asked to review psychophysical scaling procedures, I take the task quite literally, by which I mean to review certain basic topics, that is, to view them again—to take another look at them with the hope that examining them from a new perspective perhaps will give new insight into some of the complicated issues and perplexing problems that continue to beset psychophysics. Reviewing can mean taking a very fresh look; it can even mean reconsidering premises that previously may have seemed obvious. What I want to review are those methods that call upon people to make quantitative or quasi-quantitative judgments about their subjective states (about sensations, perception, attitudes, or whatever). By and large, these methods are magnitude estimation and magnitude production on the one hand, and various types of rating (numerical, adjectival, graphic) on the other.
