Psychophysical Scaling'"

their helpful criticisms of a preliminary draft of this chapter. A special word of thanks is due Dr. Stevens, u~ho, in addition to discovering seueral errors of fact and a nutnber of stylistic blunders, forced us to reconsider some of our views on various aspects of scaling. His comments coupled wzth our own misgivings resulted in a complete revision oj'the section on magnitude estimation and t...

Psychophysical Scaling of Sonification Mappings

We determined preferred data-to-display mappings by asking experiment participants directly and then examined the psychophysical scaling functions relating perceived data values to underlying acoustic parameters. Presently, we are extending and validating the scaled mappings in practical data interpretation tasks. The resulting scaling functions, in conjunction with the experimental paradigm de...

Achieving across-laboratory replicability in psychophysical scaling

It is well known that, although psychophysical scaling produces good qualitative agreement between experiments, precise quantitative agreement between experimental results, such as that routinely achieved in physics or biology, is rarely or never attained. A particularly galling example of this is the fact that power function exponents for the same psychological continuum, measured in different...

Measuring tinnitus loudness using constrained psychophysical scaling.

PURPOSE We measured tinnitus loudness using a new method of psychophysical scaling with the aim of introducing a potentially useful new procedure to the literature. METHOD Fourteen adults reporting tinnitus were trained to use a standardized loudness scale, and then they used that response scale to assess loudness of nonstandard stimuli and of their tinnitus. We also measured tinnitus loudnes...
