Establishing operations can alter problem behaviors by changing the momentary value of reinforcers associated with those problem behaviors. If establishing operations (EOs) precede the presentation of discriminative stimuli (SDs) for problem behaviors, it may be possible to introduce neutralizing routines that both reduce the value of reinforcers associated with problem behaviors and decrease the occurrence of problem behaviors. The present study examined this logic with 3 adolescents with severe intellectual disabilities. Initial functional analyses indicated that problem behaviors were motivated by either escape or tangible items. Functional assessment interviews identified possible establishing operations that were associated with the occurrence of problem behavior and indicated that these establishing operations occurred over 1 hr before presentation of the SD for problem behaviors. We used an alternating treatments design to examine problem behaviors during instruction under four conditions: EO + SD, SD only, EO only, and neither SD nor EO. For all 3 participants, problem behaviors occurred almost exclusively during the EO + SD condition. A further analysis compared the EO + SD condition when neutralizing routines were embedded between the EO and the SD. Results from an ABAB reversal design supported the effectiveness of neutralizing routines to reduce these problem behaviors. Applied and theoretical implications are discussed.
建立性操作可以通过改变与问题行为相关的强化物的即时价值来改变问题行为。如果建立性操作(EOs)先于问题行为的辨别性刺激(SDs)出现,那么引入中和程序可能是可行的,这种程序既能降低与问题行为相关的强化物的价值,又能减少问题行为的发生。本研究对3名重度智力残疾青少年验证了这一逻辑。最初的功能分析表明,问题行为的动机是逃避或获取实物。功能评估访谈确定了可能与问题行为发生相关的建立性操作,并表明这些建立性操作在问题行为的辨别性刺激出现前1个多小时就已发生。我们采用交替治疗设计,在四种条件下考察教学过程中的问题行为:建立性操作+辨别性刺激、仅辨别性刺激、仅建立性操作,以及既无辨别性刺激也无建立性操作。对于所有3名参与者,问题行为几乎只发生在建立性操作+辨别性刺激的条件下。进一步的分析比较了在建立性操作和辨别性刺激之间嵌入中和程序时的建立性操作+辨别性刺激条件。ABAB反转设计的结果支持了中和程序减少这些问题行为的有效性。本文还讨论了其应用和理论意义。
