Abstract
Eight pigeons pecked keys under multiple variable-interval two-minute variable-interval two-minute schedules. In Experiment 1, the reinforcers were 2, 4, or 8 seconds access to a food magazine. In Experiments 2 and 3, the reinforcers were grains that had been determined to be most-, moderately-, or non-preferred. Both positive and negative behavioral contrast occurred when the reinforcers in one component were held constant and the duration or type of reinforcer obtained in the other component varied. Undermatching occurred when the relative rate of responding during a component was plotted as a function of the relative duration of the reinforcers in that component.
摘要
八只鸽子在多个可变间隔两分钟可变间隔两分钟的时间表下啄键。在实验 1 中，强化物是 2、4 或 8 秒的食物杂志访问权限。在实验 2 和 3 中，强化物是已经确定为最优先、中等优先或非优先的谷物。当一个成分中的强化物保持不变，而另一个成分中获得的强化物的持续时间或类型变化时，会出现正性和负性行为对比。当将一个成分中的相对反应率作为该成分中强化物的相对持续时间的函数绘制时，就会出现不匹配。
