Memory for psychophysical scaling judgments

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...

A Psychophysical Law for Linguistic Judgments

It has been argued that linguistic acceptability can be estimated using the psychophysical technique of magnitude estimation, in the same way as physical continua such as brightness and loudness (Bard, Robertson, & Sorace, 1996; Cowart, 1997). For physical continua, plotting the perceived stimulus magnitude against the actual physical magnitude results in a power relationship, the Psychophysica...

Higher order sequential effects in psychophysical judgments.

We found that the depth of sequential effects depends on the judgment task. An experiment with squares indicated that stimulus-response pairs up to two trials back were included in the judgment process when subjects were required to make category judgments of size, whereas only the immediately preceding event was incorporated when subjects were making magnitude estimations. In the case of categ...

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...
