The key pecking responses of six pigeons were reinforced in the presence of a bisected response key when both halves were of equal wavelength; responses to non-matching presentations were not reinforced. Subsequent generalization tests involving novel non-matching stimuli were conducted in extinction. The results indicated the acquisition of a conceptual color matching discrimination; however, post-discrimination training peak shifts may interfere with the demonstration of the concept of color matching.
