Measurement and Learning
AbstractExperimental measurement in psychology commonly refers either to psychophysics orpsychometrics. The metrology behind psychophysics presumes that numbersâ€”invariant to some plausible transformsâ€”can represent psychological experience, and inthis way display experience as functionally related to physical metrics. So, for example,experienced â€loudnessâ€ can be systematically related to acoustical power. The success ofthis enterprise can be appreciated by the application of such metrics to variouspalliatives or other practical ends, viz: eyeglasses or hearing aids.
