Pigeons were trained to peck on a fixed‐interval schedule of food reinforcement and then exposed to three schedules in which there was either no, or an indirect, relation between pecking and food delivery: (a) a conjunctive schedule in which food was delivered at fixed intervals, providing at least one peck was emitted in the interval; (b) a recycling version of the conjunctive schedule that essentially eliminated occasional peck‐food contiguities (recycling conjunctive); (c) delivery of food at fixed intervals independently of the birds' behavior (fixed time). The rates and patterns of pecking sustained by these procedures depended on interfood interval and relative proximity of pecks to food.
