title: d-Amphetamine discrimination established under a conditional discrimination procedure in pigeons.
abstract: Pigeons were brought under discriminative control of d-amphetamine vs saline injections. Two colored stimuli, blue and green, were presented on a key, and the pecking response to one of them was reinforced under Random Interval 30 sec, whereas key pecks to the other were extinguished. The schedule associated with each colored light was conditional on pharmacological treatment: pecks to the blue stimulus were reinforced when d-amphetamine had been injected, and pecks to the green stimulus, following saline injection. Control by injection was established, and dose-response curves resembled that obtained under two- or three- key choice training procedures.
