Abstract:

Data claiming to show a reversal of the classical contrast effect in temperature perception seem instead to bring the temperature aftereffect into the class of aftereffects which show a distance paradox. The amount of direct contrast first increases and then decreases as the temperature differential between the adapting and test objects increases. Reversed contrast does not seem to occur. The form of the distance paradox function is like that of the distance paradox function in many other perceptual dimensions and probably demands a similar explanation. The effect of prolonged adaptation, however, is the opposite of the effect found in most figural aftereffects. Author
