Abstract

The detectability of a brief color shift towards red or towards green of a foveally viewed yellow target is less by 25% if the observer is uncertain as to the direction of the color shift. This result matches a prediction of the theory of signal detectability: When signal parameters become uncertain, detectability declines.

(a) Optical system: Subject viewed monocularly through a 2 mm artificial pupil. A beam splitter allowed the superposition of two targets: a red light-emitting diode (LED) and a green LED. (b) Composite target. Rectangular surround had luminance of 8 cd/m2 provided by 7½ W tungsten lamp. Luminance of the superimposed LED’s, subtending 15′, was 13 cd/m2 (SEI photometer).
