Yоu cоnduct аn experiment with the fоllowing procedures: When а key is illuminаted red, key pecks produce food. When the key is illuminated green, key pecks do not produce food. When the key is illuminated blue, pressing a foot lever changes the key from blue to red. The pigeon can then peck the red key to obtain food. Across training, lever pressing increases because it produces access to the red key, which signals reinforcement is available in the form of food for key pecking. Match each description with the appropriate stimulus function.
