The Gutman & Kalish Procedure for measuring Stimulus Control in Birds.

Acquisition Phase: S+ = key lit at 580nm S - = unlit key

Test Phase: presentation of 11 stimuli (530nm through 630nm) in random order in 12 different blocks; responses are not reinforced.

Stimulus Generalization as a Measure of Stimulus Control After Guttman & Kalish, 1956 Pigeons were trained to peck in the presence of a colored light of 580 nm wavelength and then tested in the presence of other colors. Training S+
