Discriminable transitions from relatively favorable schedules of reinforcement to unfavorable schedules (rich-lean transitions) can produce disruptions in operant behavior. A prior evaluation in our laboratory (Toegel et al., 2021) found that placing a border around a key displayed on a resistive touchscreen increased pigeons' response accuracy relative to conditions without the border. We sought to evaluate (a) whether effects of the key border on accuracy could be replicated in a within-session comparison and (b) whether transitions from a response alternative associated with accurate responding to one associated with inaccurate responding functioned as rich-lean transitions. Pigeons' key pecks were reinforced according to a two-component multiple schedule with identical fixed-ratio (FR) requirements and reinforcer magnitudes. The components differed based on whether the virtual key was displayed behind a border or with no border. In line with prior research, within-session comparisons yielded higher response accuracy in components with the key border than in components without the border. Furthermore, transitions from the border component to the no border component functioned as rich-lean transitions for pigeons whose obtained FRs in no border components were substantially larger than the FR programmed in that component.
从相对有利的强化计划到不利的强化计划（从丰富到贫瘠的转变）的可区分转变可以破坏操作性行为。我们实验室的先前评估（Toegel 等人，2021）发现，在电阻式触摸屏上显示的钥匙周围设置边框可以提高鸽子相对于没有边框的条件的反应准确性。我们试图评估：（a）在会话内比较中，钥匙边框对准确性的影响是否可以复制，以及（b）从与准确反应相关的反应替代物到与不准确反应相关的反应的转变是否作为丰富到贫瘠的转变起作用。根据具有相同固定比率（FR）要求和强化物大小的两个组件的多重时间表，对鸽子的关键啄击进行强化。组件之间的差异基于虚拟钥匙是显示在边框后面还是没有边框。与先前的研究一致，会话内比较在带有边框的组件中产生了比没有边框的组件更高的反应准确性。此外，对于在没有边框的组件中获得的 FR 远大于该组件中编程的 FR 的鸽子，从边框组件到没有边框组件的转变起到了丰富到贫瘠的转变的作用。
