Quick Reference

An index of perceptual constancy given by (RS)/(AS), where R is the physical magnitude or intensity of the stimulus chosen as a match, S is the physical magnitude or intensity for a stimulus match with zero constancy, and A is the physical magnitude or intensity that would be chosen under 100 per cent constancy. The ratio is equal to zero when there is no perceptual constancy and 1 when there is perfect constancy. Because sensation increases as the logarithm of physical magnitude or intensity, according to Fechner's law, a modified version called the Thouless ratio was introduced in 1931. See also Brunswikian. [Named after the Hungarian-born US psychologist Egon Brunswik (1903–55), who introduced it in 1929]
