1. This investigation has been concerned with an analysis of brightness discrimination as it is influenced by the duration of ΔI. The durations used extend from 0.002 second to 0.5 second. 2. ΔI/I values at constant intensity are highest for the sh

Measures are made of changes in test wavelength required to compensate for a contrast effect introduced by a background color. The test hue remains constant when the contrast effect is modified by a shift of the test wavelength, usually toward the di

Hecht’s equation for brightness discrimination adequately accounts for results obtained with a constant duration of ΔI. When the duration of ΔI is varied, the constants of the equation assume different values.
