Abstract
Differential sensitivity to grit and weight stimuli was compared for lateral differences using power law coefficients based on unanchored magnitude estimations. Ss were 120 college students run in a parametric design with sex, handedness, and order of testing right and left controlled. Findings on lateral differences were unreliable. Power law functions were shown to fit group (N = 10) data consistently but not individuals. These results indicate that without specification of several implicated variables, the use of UME and the power law to compare sensory functions in individuals is of dubious validity.
