The frequency-response characteristics of channels used in human vibrotaction were studied by using a psychophysical tuning-curve paradigm derived from auditory research. Sinusodial 200-msec vibratory bursts delivered to the thenar eminence of the hand were detected in the presence of sinusodial maskers delivered to the same skin area either continuously or pulsed in forward masking. Psychophysical tuning curves were obtained by determining the intensity of maskers of varied frequency necessary to mask a 10-dB SL test stimulus of fixed frequency. The results support the notion that at least two independent channels operate in human vibrotaction. There was no evidence for frequency selective mechanisms other than those at the periphery. Psychophysical tuning curves were similar to neural tuning curves for individual cutaneous mechanoreceptors.
