Abstract
Three experiments which employed the psychophysical method of direct magnitude estimation were conducted in order to scale the stimulus dimension of size via active touch perception. Power functions were adequately fitted to the data for both one-trial and multi-trial presentations of an assigned modulus. Results obtained when Ss provided their own primary modulus were characterized by small, nondiscriminating ranges of size estimation. Various sensing and exploring movements made by Ss during the active touch perception tasks were discussed.
