The finding that differential reinforcement of alternative behavior (DRA) is efficacious at 80% integrity when continuous reinforcement is programmed for alternative responding may have contributed to a perception that integrity at 80% or above is acceptable. However, research also suggests that other interventions (e.g., noncontingent reinforcement) may not remain effective at 80% integrity. The conditions under which 80% integrity is acceptable for common behavioral interventions remains unclear. Therefore, we conducted two human-operant studies to evaluate effects of 80% integrity for interventions with contingent or noncontingent intermittent reinforcement schedules. During Experiment 1, we compared noncontingent reinforcement (NCR) and DRA when implemented with 80% integrity. During Experiment 2, we compared 2 variations of DRA, which included either a ratio or interval schedule to reinforce alternative behavior. Results replicated previous research showing that DRA with a FR-1 schedule programmed for alternative responding resulted in consistent target response suppression, even when integrity was reduced to 80%. In contrast, neither NCR nor interval-based DRA were consistently effective when implemented at 80% integrity. These results demonstrate that 80% integrity is not a uniformly acceptable minimal level of integrity.
当为替代反应安排连续强化时，发现替代行为的差别强化（DRA）在80%的完整性水平上是有效的，这可能导致了一种观念，即80%或更高的完整性是可以接受的。然而，研究也表明，其他干预措施（如非连续强化）在80%的完整性水平上可能不再有效。常见行为干预在80%的完整性水平下可接受的条件仍不明确。因此，我们进行了两项人类操作性研究，以评估80%的完整性对有条件或无条件间歇性强化计划干预的影响。在实验1中，我们比较了以80%的完整性实施时的非连续强化（NCR）和DRA。在实验2中，我们比较了DRA的两种变体，其中包括强化替代行为的比率或间隔计划。结果重复了先前的研究，表明当为替代反应安排FR-1计划时，即使完整性降至80%，DRA也会导致一致的目标反应抑制。相比之下，当以80%的完整性实施时，NCR和基于间隔的DRA都没有持续有效。这些结果表明，80%的完整性不是一个统一可接受的最低完整性水平。
