Vibrotactile masking: Effects of oneand two-site stimulation

Abstract

Masked vibrotactile thresholds at the index fingertip were measured as a function of masker intensities, which were applied to the thenar eminence of the same hand. Test and masker frequencies were selected so that the Pacinian and non-Pacinian receptor systems were selectively activated. Remote-site masking was effective only when both masker and test stimulus were within the frequency range of the Pacinian system. Cross-channel masking did not occur. © 1983 Psychonomic Society, Inc.
