Three pigeons were studied under two-key concurrent variable-interval schedules with food as the reinforcer on one key and ectostriatal brain stimulation as the reinforcer on the other. Brain-stimulation parameters were kept constant while the rate of food reinforcement availability was varied. The results showed that qualitatively different reinforcers could be handled in the same theoretical framework that applies when choice is between different rates, immediacies, and amounts of a single reinforcer.
三只鸽子在两个关键的同时可变间隔程序下进行研究,其中一个关键的强化物是食物,另一个关键的强化物是外纹状体脑刺激。在保持脑刺激参数不变的情况下,改变食物强化可用性的速度。结果表明,在选择不同的强化物的速度、即时性和数量时适用的相同理论框架中,可以处理不同质的强化物。
