title: Operant-Pavlovian interactions: The effect of the number of stimuli with free-food depends on the operant baseline.
abstract: Four groups of three pigeons were trained to respond under operant schedules which varied with respect to response rate requirements and reinforcement frequency. The number of short duration stimuli preceding free food was manipulated in different experimental conditions. Operant behavior was maintained on one key, while stimuli were presented on another key. Stimulus key response rates, latencies to the first response on the stimulus key and the percentage of stimuli responded to did not vary as a function of the number of stimuli presented, but were dependent upon the reinforcement frequency of the operant baseline.
