Abstract
Stevens’ idea of “direct measurement” of stimulus magnitude is extended to the direct measurement of stimulus differences. An important extension of Wave Theory provides predictions of response probabilities from single direct measures of comparative difference. As an illustration of the method, in an experiment 20 university students compared, only once, each of 16 job pairs, judging which has the larger salary and creating the size of salary differences. The correlation between a theoretical measure of the size of perceived salary difference and the direct measures of perceived salary difference is 0.99. The probability of correctly predicting individual binary choices between jobs, based on the students’ generated measures of perceived stimulus difference, ranges to 1.00 from 0.935. This new theory draws together Stevens and Fechner by showing that they perceived the same underlying psychological events through perfectly related measures of subjective experience.
期刊介绍：
The Journal of Mathematical Psychology includes articles, monographs and reviews, notes and commentaries, and book reviews in all areas of mathematical psychology. Empirical and theoretical contributions are equally welcome.
Areas of special interest include, but are not limited to, fundamental measurement and psychological process models, such as those based upon neural network or information processing concepts. A partial listing of substantive areas covered include sensation and perception, psychophysics, learning and memory, problem solving, judgment and decision-making, and motivation.
The Journal of Mathematical Psychology is affiliated with the Society for Mathematical Psychology.
Research Areas include:
• Models for sensation and perception, learning, memory and thinking
• Fundamental measurement and scaling
