ABSTRACT
One of the enduring tasks of psychophysics is to provide models concerning the ability of perceptual systems to transmit and accurately code information from the surrounding world. One experimental technique used extensively to determine the amount of information transmitted is the Method of Absolute Identification (Baird & Noma, 1978), formerly referred to as the Method of Absolute Judgment (Wever & Zener, 1928). The procedure is deceptively simple. The subject must assign a unique response label to each of a set of stimuli distributed along a physical dimension. The labels are usually the integers 1 to N, where N is the total number of stimuli. The physical values are typically separated by equal logarithmic steps, and following each response, subjects receive feedback as to the correct label for that trial.
