Pigeons were trained to respond to two stimuli on the wavelength continuum, 550 nm and 570 nm, each correlated with an independent schedule of reinforcement. The multiple schedule component in effect during 550 nm (SI) was always a variable‐interval 1‐min. During the 570‐nm stimulus (S2) the second component of the schedule was either variable‐interval 30‐sec, 1‐min, 2‐min, 5‐min, or extinction for different groups of birds. Generalization gradients were obtained after this training, with the following results: (1) response rate to SI during training was related to the reinforcement frequency associated with S2; the distribution of responding during generalization testing was a function of the schedules of reinforcement used during training and the response rates they produced. Decreases in the relative frequency of reinforcement correlated with S2 resulted in increases in the distribution shift of responses away from S2 during generalization testing.
