Resurgence refers to an increase of a previously reinforced target behavior following the worsening of conditions for a more recently reinforced alternative behavior. There is evidence to suggest that alternative reinforcers of greater magnitude are more effective at reducing target responding but may also result in more resurgence when removed. Similar effects have been observed with high rates of alternative reinforcement. However, in clinical settings, reinforcement rate thinning is used to reduce the likelihood of resurgence associated with higher rates of alternative reinforcement. Given the clinical importance of alternative reinforcer magnitude, it is necessary to evaluate how reinforcer magnitude thinning may impact resurgence as well. Following Phase 1 in which target responding was reinforced, rats earned either large (six pellets), small (one pellet), or thinned (reduced from six pellets to one across sessions) magnitude reinforcement for alternative responding during target-response extinction in Phase 2. Then, alternative responding was placed on extinction for all groups in Phase 3. Target responding was comparably elevated at the end of Phase 2 for groups Small and Thin compared to group Large. In Phase 3, resurgence was evident only in group Large but target responding remained relatively elevated in groups Small and Thin. These results provide additional evidence of the important interplay between conditions of alternative reinforcement and the persistence and resurgence of target responding.

替代强化的大、小和变薄幅度对复苏的影响

复苏是指在最近强化的替代行为的条件恶化之后,先前强化的目标行为的增加。有证据表明,更大程度的替代强化物在减少目标反应方面更有效,但在移除时也可能导致更多的复苏。在高替代强化率下也观察到了类似的效果。然而,在临床环境中,强化率变薄用于降低与较高替代强化率相关的复发的可能性。鉴于替代强化物强度的临床重要性,有必要评估强化物强度变薄如何影响复苏。在加强目标响应的第 1 阶段之后,大鼠获得大(六粒),在阶段 2 的目标反应消退期间,小(一个颗粒)或变薄(从六个颗粒减少到一个)幅度增强,用于替代响应。然后,在阶段 3 中,所有组的替代响应都被置于消退状态。目标响应是与大型组相比,小型组和瘦型组在第 2 阶段结束时相对升高。在第 3 阶段,复苏仅在大型组中很明显,但目标响应在小型组和瘦组中仍然相对较高。这些结果为替代强化条件与目标响应的持久性和复苏之间的重要相互作用提供了额外的证据。在第 3 阶段,所有组的替代响应都被置于灭绝状态。与大型组相比,在第 2 阶段结束时,小型组和瘦组的目标响应相对较高。在第 3 阶段,复苏仅在大型组中很明显,但目标响应在小型组和瘦组中仍然相对较高。这些结果为替代强化条件与目标响应的持久性和复苏之间的重要相互作用提供了额外的证据。在第 3 阶段,所有组的替代响应都被置于灭绝状态。与大型组相比,在第 2 阶段结束时,小型组和瘦组的目标响应相对较高。在第 3 阶段,复苏仅在大型组中很明显,但目标响应在小型组和瘦组中仍然相对较高。这些结果为替代强化条件与目标响应的持久性和复苏之间的重要相互作用提供了额外的证据。
