Abstract

The effects of the rate of temperature change and adapting temperature on human thermal sensitivity were examined with a magnitude estimation technique. Suprathreshold cool and warm stimuli ranging in intensity from 1 to 5°C were presenttd at 0.5, 1, and 2°C/sec from a number of adapting temperatures. Sensitivity to cool and warm stimuli did not vary with rate. Sensitivity was, however, markedly altered as the adapting temperature was varied from 25 to 40°C. The influence of rate of temperature change and of adapting temperature on sensitivity to suprathreshold thermal stimuli parallels that described by others for sensitivity to threshold stimuli.
