When a functional communication response (FCR) can be reliably occasioned, destructive behavior tends to be lower. However, the form of FCR may affect the durability of functional communication training, as missing FCR materials may promote resurgence. Experiment 1 demonstrated that resurgence of target responding was lower when a vocal FCR remained available but was placed on extinction compared to when a card-based FCR was unavailable. Experiment 2 replicated the finding that initiating treatment with a card FCR produced less target responding than when initiating treatment with a vocal FCR. We then evaluated a set of procedures for transitioning the card FCR to the previously unlearned vocal FCR. These findings suggest benefits of training different types of FCRs at different stages of treatment and provide a preliminary set of procedures for transitioning between FCR topographies while occasioning minimal target responding.
当能够可靠地引发功能性沟通反应 (FCR) 时，破坏性行为往往会减少。然而，FCR 的形式可能会影响功能沟通训练的持久性，因为缺失的 FCR 材料可能会促进反应的重现。实验 1 表明，与卡片 FCR 不可用时相比，当保留可用的语音 FCR 但将其置于灭绝状态时，目标反应的重现率较低。实验 2 复制了这样的发现，即用卡片 FCR 开始治疗会产生比用语音 FCR 开始治疗更少的目标反应。然后，我们评估了一组将卡片 FCR 转换为先前未学习的语音 FCR 的程序。这些发现表明，在治疗的不同阶段训练不同类型的 FCR 具有益处，并提供了一组初步的程序，用于在引发最小目标反应的情况下在 FCR 地形之间进行转换。
