The effect of adapting speed, duration, and distance on the tactile motion aftereffect.
We investigated the effect of adapting speed, duration, and distance on the frequency of occurrence, duration, and vividness of the tactile motion aftereffect (tMAE). Using a cylindrical drum with a patterned surface we adapted the glabrous surface of the right hand at two speeds (14 and 28 cm/s) and three durations (60, 120, and 240 s). Distance was explored in the interaction of adapting speed and duration. The results showed that the frequency of occurrence, duration, and vividness of the tMAE increased with adapting speed. There was also a positive relationship between adapting duration and the frequency of occurrence, but not the duration or vividness, of the illusion. Distance was only a factor when it came to the duration of the tMAE. Taken together, these results show the importance of adapting parameters, particularly speed, on the tMAE.
