Abstract
Preliminary experiments showed that Os can make consistent judgments of tactual roughness and smoothness. The stimuli were 12 grits of emery cloth. Magnitude estimations of roughness and smoothness produced straight lines when plotted (log-log) against grit number. The exponents of these power functions were determined in two experiments with magnitude estimation and one with cross-modality matching against loudness. All three experiments gave results that were power functions of grit number with exponents in the vicinity of[long dash]1.5 for roughness and +1.5 for smoothness. The cross-modality matches also confirmed the exponents determined by magnitude estimation.
