We examined the effects of the presence and absence of punishment on the resurgence and renewal of extinguished operant behavior with zebrafish. With resurgence, food deliveries reinforced target responding in Phase 1 was exposed to shock punishment plus extinction (PUN + EXT) versus extinction alone (EXT) while introducing alternative reinforcement in Phase 2. All contingencies were discontinued in Phase 3. With renewal, target reinforcement during Phase 1 occurred in Context A and then during Phase 2 was exposed to either PUN + EXT or EXT in Context B. All contingencies were discontinued in Context A during Phase 3. During Phase 2 for both resurgence and renewal, decreases in target responding were more rapid with PUN + EXT than EXT. During testing in Phase 3, resurgence was less following PUN + EXT than EXT. In contrast, renewal was greater following PUN + EXT than EXT but differences in response rates at the end of Phase 2 complicated the interpretation. We discuss these differences between resurgence and renewal as due to differences in learning about alternative reinforcement (resurgence) versus more general contextual changes (renewal).
我们研究了有无惩罚对斑马鱼消退的操作性行为的恢复和更新的影响。在恢复实验中，第一阶段通过食物递送强化的目标反应，在第二阶段引入替代强化时，一组接受电击惩罚加消退（PUN + EXT），另一组仅接受消退（EXT）。第三阶段停止所有应急措施。在更新实验中，第一阶段在情境A中进行目标强化，然后在第二阶段在情境B中接受PUN + EXT或EXT。第三阶段在情境A中停止所有应急措施。在恢复和更新实验的第二阶段，PUN + EXT组的目标反应下降速度比EXT组更快。在第三阶段的测试中，PUN + EXT组的恢复比EXT组少。相比之下，PUN + EXT组的更新比EXT组更大，但第二阶段末反应率的差异使解释变得复杂。我们认为恢复和更新之间的这些差异是由于在学习替代强化（恢复）与更一般的情境变化（更新）方面存在差异。
