Six pigeons were trained to respond on two keys, each of which provided reinforcers on an arithmetic variable-interval schedule. These concurrent schedules ran nonindependently with a 2-s changeover delay. Six sets of conditions were conducted. Within each set of conditions the ratio of reinforcers available on the two alternatives was varied, but the arranged overall reinforcer rate remained constant. Each set of conditions used a different overall reinforcer rate, ranging from 0.22 reinforcers per minute to 10 reinforcers per minute. The generalized matching law fit the data from each set of conditions, but sensitivity to reinforcer frequency (a) decreased as the overall reinforcer rate decreased for both time allocation and response allocation based analyses of the data. Overall response rates did not vary with changes in relative reinforcer rate, but decreased with decreases in overall reinforcer rate. Changeover rates varied as a function of both relative and overall reinforcer rates. However, as explanations based on changeover rate seem unable to deal with the changes in generalized matching sensitivity, discrimination accounts of choice may offer a more promising interpretation.
六只鸽子被训练在两个键上做出反应，每个键都在算术变时距程序上提供强化物。这些并发程序以 2 秒的转换延迟非独立运行。进行了六组条件实验。在每组条件中，两种选择上可用的强化物的比率不同，但安排的总体强化物率保持不变。每组条件使用不同的总体强化物率，范围从每分钟 0.22 个强化物到每分钟 10 个强化物。广义匹配律适用于每组条件的数据，但基于时间分配和反应分配的数据分析表明，对强化物频率的敏感性（a）随着总体强化物率的降低而降低。总体反应率不会随相对强化物率的变化而变化，但会随总体强化物率的降低而降低。转换率随相对和总体强化物率的变化而变化。然而，由于基于转换率的解释似乎无法处理广义匹配敏感性的变化，因此选择的辨别解释可能提供更有前途的解释。
