“…While the effect was modest (approximately 0.5 dB on average), and varied from subject to subject, the same general pattern of results was obtained in all three subjects. Similar adaptation-produced sharpening of discriminative ability has previously been demonstrated in audition (von B6k6sy, 1929/1960), vision (Greenlee and Heitger, 1988;Ranke, 1952;Beverly, 1983, 1985), and taste (McBurney et al, 1967). Its extension here to vibrotaction suggests that it is a general principle of sensory adjustment to environmental stimulation.…”

Human psychophysical detection and amplitude discrimination thresholds for 25-Hz sinusoidal vibrations were measured on the thenar eminence using two-interval forced-choice tracking, in the unadapted state and following exposure to 25-Hz adapting stimuli representing a range of amplitudes (5-25 dB SL). As expected, detection threshold was elevated 6 to 7 dB for each 10-dB increase in the adapting stimulus. In contrast, amplitude difference thresholds for 10 and 20 dB SL standard stimuli were generally lowest when the amplitude of the adapting stimulus was equal to the amplitude of the standard. The results indicate that while adaptation impairs detection of a liminal vibrotactile stimulus, it improves intensity discrimination of supraliminal stimuli that are close in amplitude to the adapting stimulus. The compatability between these results and a recently proposed model of cortical dynamics (Whitsel et al., 1989) suggests that cortical events may contribute significantly to the physiological basis of vibrotactile adaptation.

“…Between stimuli the participant rinsed the mouth with distilled water. Each stimulus was separated by a minimum of 30 s to minimize adaptation (Bartoshuk et al, 1964;McBurney et al, 1967).…”

“…In addition, the frequency of a correct response in the method of constant stimuli increases as a normal integral with respect to ΔX, at least for small values of ΔX (e.g., [79,83,84], [85]-data re-presented in [86,87]- [88,89]). It follows that d' increases in proportion to ΔX, and if ΔX θ is the value of ΔX affording 84% correct responses (equivalent to d' = 1), (ΔX θ ) -2 is proportional to the divergence of the discrimination.…”

This paper presents, first, a formal exploration of the relationships between information (statistically defined), statistical hypothesis testing, the use of hypothesis testing in reverse as an investigative tool, channel capacity in a communication system, uncertainty, the concept of entropy in thermodynamics, and Bayes' theorem. This exercise brings out the close mathematical interrelationships between different applications of these ideas in diverse areas of psychology. Subsequent illustrative examples are grouped under (a) the human operator as an ideal communications channel, (b) the human operator as a purely physical system, and (c) Bayes' theorem as an algorithm for combining information from different sources. Some tentative conclusions are drawn about the usefulness of information theory within these different categories. (a) The idea of the human operator as an ideal communications channel has long been abandoned, though it provides some lessons that still need to be absorbed today. (b) Treating the human operator as a purely physical system provides a platform for the quantitative exploration of many aspects of human performance by analogy with the analysis of other physical systems. (c) The use of Bayes' theorem to calculate the effects of prior probabilities and stimulus frequencies on human performance is probably misconceived, but it is difficult to obtain results precise enough to resolve this question.
