Threshold influence on vibrotactile magnitude production scaling

Abstract

The present investigation attempted to look at possible influences that the obtainment of vibrotactile threshold might have on the power function exponent derived from magnitude production scaling. Two groups of six subjects each provided vibrotactile magnitude functions for the lingual dorsum and thenar eminence of the right hand. Group 1 was required to provide a series of vibrotactile thresholds on the test structures prior to scaling. Group 2 performed the scaling task only. Results showed that the inclusion of the threshold task within the test paradigm had no influence on the subsequent scaling activity. © 1984, Psychonomic Society, Inc.. All rights reserved.
