A Response Time Theory of Perceptual Independence

  • F. Gregory Ashby

Part of the Recent Research in Psychology book series (PSYCHOLOGY)


A response time theory of perceptual independence is developed by incorporating an assumption, called the RT-distance hypothesis, into the framework of general recognition theory (Ashby & Townsend, 1986). The RT-distance hypothesis states that response time is inversely related to the distance from the perceptual representation of a stimulus to the nearest decision bound. Two new experimental paradigms are proposed and response time tests of perceptual independence that utilize these paradigms are developed. An empirical application validates one of these tests. Methods for examining aspects of the underlying perceptual distributions are also discussed.
