Abstract
8 Ss were exposed to vibrotactile stimulation of 250 Hz, applied to the tip of the left index finger. Seven stimulus intensities, ranging from 26 to 48 db, were each combined with three stimulus durations, 50, 250, and 1200 msec. A magnitude-estimation technique with fixed standard was employed to obtain scale values of the apparent duration of each stimulus. The results indicate that apparent duration can be described as a logarithmic function of stimulus intensity. This conclusion is in line with our previous findings concerning apparent duration of electrical stimulation.Keywords
