Abstract
Data from a previously reported expt. involving simultaneous comparison of the firmness of different types of material which may be deformed between finger and thumb, are reconsidered. The data was fitted approx. to a phi-gamma function. The concept of fractional differentiation is developed to explain the relationship between subjective judgments and objective measurements.Keywords
