Abstract：
Resurgence is an increase in an extinguished operant response resulting from a worsening of conditions (e.g., extinction) for a more recently reinforced alternative behavior. Previous research has shown that exposure to cycles of alternative reinforcement available versus unavailable (i.e., on/off alternative reinforcement) across sessions can reduce subsequent resurgence. Most previous assessments of the procedure have examined target operant responding during only single-session resurgence tests, and it remains unclear if exposure to relatively few cycles of on/off alternative reinforcement can maintain low rates of target behavior across extended exposure to extinction. This experiment with rats examined the effects of 4 or 8 cycles of on/off alternative reinforcement on subsequent resurgence during a 10-session extinction test. The results show that exposure to 4 cycles of on/off alternative reinforcement is as effective as 8 cycles in producing low rates of target behavior during treatment and across extended extinction. This result is consistent with extant theories of resurgence and suggests that on/off alternative reinforcement could have translational utility following relatively few cycles of exposure.
摘要：
死灰复燃是指由于条件恶化而导致的熄灭操作反应的增加(例如，灭绝)，用于最近强化的替代行为。先前的研究表明，暴露于可用的替代钢筋循环与不可用的循环(即，开/关替代强化)可以减少随后的复苏。以前对该程序的大多数评估都仅在一次会议的复苏测试中检查了目标操作员的反应，目前尚不清楚暴露于相对较少的开/关替代强化周期是否可以在长期暴露于灭绝期间保持较低的目标行为率。这项针对大鼠的实验检查了4或8个周期的开/关交替增强对10个疗程的消光测试中随后的复苏的影响。结果表明，暴露于4个周期的开/关替代增强作用与8个周期一样有效，在治疗期间和整个消光过程中产生低速率的目标行为。此结果与现有的复苏理论一致，并表明开/关替代加固可以在相对较少的暴露周期后具有平移效用。
