Duration discrimination of brief light flashes

Abstract

The data from four experiments indicate that when Os discriminate between light flashes of different durations, for durations for which Bloch's law has been shown to hold, their discriminations are frequently made on the temporal information available in the flashes rather than on their apparent brightness. A model for duration discrimination which specifies that discriminability depends only on the difference in duration between the two brief flashes, and is independent of their durations, is presented and applied to the data. © 1971 Psychonomic Society, Inc.
