Abstract
In vision, after prolonged seeing of motion in one direction, illusory motion in the opposite direction is observed in physical static visual patterns (known as "waterfall illusion"). This phenomenon is referred to as Motion After Effect (MAE). MAE has been useful to study, without brain imaging, information processing in visual perception. Although some tactual illusions have been observed, obvious tactual MAE has not been reported. We, however, found clear and robust MAE in tactile sensation by using physical motion stimuli for test probe. We suppose that this research will make a contribution to investigate mechanism of tactual motion perception.
