Abstract
Three groups of Ss judged 2-,4-,8-,16-, and 32-sec. durations of time presented through flash of light by fractionation, multiplication, and category methods. The stimuli were controlled by a Hunter timer and the ratio production judgments recorded by a Standard Electric .01-sec. clock. Apparent duration appeared to grow as the 1.02 power of stimulus magnitude while the category scale was nonlinear. Discrepancies in half and double judgments were found which were ascribed to the underestimating bias throughout the stimulus range.Keywords
