Ascending vibrotactile lingual thresholds were obtained for 110 Ss at 200 and 400 Hz. Mean thresholds and standard deviations were reported in microns. Although frequency differences were observed, comparatively small standard deviations reflected little inter-subject variability. Possible clinical applications were discussed.
