Effects of stimulus duration and stimulus intensity level on recovery times for lingual vibrotactile threshold shift

Abstract

The time required for lingual vibrotactile thresholds of normal young adults to return to baseline levels of sensitivity was determined following presentations of a 250-Hz stimulus for durations of 5 and 15 sec at eight different intensity levels. Results indicated that stimulus duration and stimulus intensity levels significantly affected threshold recovery time. Longer recovery times were noted for stimuli of greater duration and intensity.
