Adaptation to 1 weight was examined as a function of the temporal parameters of a spatially discrete second weight in three behavioral studies in which large series of trials in multiple sessions were presented to each of 3 Ss. A positive relation between adaptation time and stimulus intensity was observed, but the preceding weight served to decrease adaptation time to the test stimuli in all experiments. The role of neural inhibition in pressure adapation is discussed.
