| Abstract: | Measured thresholds to warming and cooling stimuli presented on the shaved skin of the inner thigh of 2 young male rhesus monkeys by the conditioned suppression method after the skin had been preadapted to 28, 30, 32, 34, 36, 38, and 40. C temperatures. Thresholds to warming stimuli decreased from .14 to .02. C, while thresholds to cooling stimuli increased from .05 to .28. C as the adapting temperature was increased from 28 to 40. C. In comparison to human thresholds, the Ss were more sensitive to changes in stimulator temperature at all adapting temperatures except to cooling at a 40. C adapting temperature. Data suggest that the Ss were able to discriminate between warming and cooling stimuli and that they responded to a change in sensation at the extreme adapting temperatures rather than to the quality of the sensation-warm or cool.
