Abstract
Four pigeons were trained to peck at either of two response-keys. Pecks at either key occasionally produced a secondary reinforcer, in the presence of which further pecks occasionally produced food, the primary reinforcer. All pigeons showed a consistent preference for variable (as compared to fixed) interval schedules of primary reinforcement.Keywords: BIRDS; CONDITIONING (PSYCHOLOGY); EXPERIMENTAL LAB STUDY; REINFORCEMENT (PSYCHOLOGY)
