Resurgence refers to an increase in a previously suppressed target behavior with a relative worsening of conditions for a more recently reinforced alternative behavior. This experiment examined the relation between resurgence and the magnitude of a reduction in the rate of reinforcement for the alternative behavior. Groups of both male and female rats initially pressed a target lever for food on a variable‐interval (VI) 30‐s schedule. In a second phase, responding to the target lever was extinguished for all groups and pressing an alternative lever was reinforced on a VI 10‐s schedule. Next, the rate of reinforcement for alternative behavior was reduced differentially across groups by arranging extinction, VI 80‐s, VI 40‐s, VI 20‐s, or continued VI 10‐s reinforcement. Target responding increased as an exponential function of the magnitude of the reduction in alternative reinforcement rates. With the exception that males appeared to show higher rates of target responding in baseline and higher rates of alternative responding in other phases, the overall pattern of responding across phases was not meaningfully different between sexes. The pattern of both target and alternative response rates across sessions and phases was well described quantitatively by the Resurgence as Choice in Context model.

替代强化率的复苏和下降。

复苏是指先前被抑制的目标行为增加，而最近强化的替代行为的条件相对恶化。该实验检验了回潮与替代行为的强化率降低幅度之间的关系。一组雄性和雌性大鼠最初按可变间隔 (VI) 30 秒的时间表按下目标杠杆以获得食物。在第二阶段，所有组对目标杠杆的反应都消失了，并按照 VI 10 秒的时间表加强了按下替代杠杆。接下来，通过安排灭绝、VI 80-s、VI 40-s、VI 20-s 或持续 VI 10-s 强化，不同组别的替代行为的强化率有所降低。目标响应增加作为替代强化率减少幅度的指数函数。除了男性在基线中表现出更高的目标响应率和在其他阶段更高的替代响应率之外，跨阶段的总体响应模式在性别之间没有显着差异。Resurgence as Choice in Context 模型在数量上很好地描述了跨会话和阶段的目标和替代响应率的模式。
