Few direct-assessment procedures are designed to identify potential negative reinforcers (e.g., including demands in the escape condition of functional analyses). Two participants were systematically exposed to a series of demands nominated by caregivers as potential negative reinforcers. Sessions ended following the first instance of problem behavior, and a hierarchy of demand aversiveness was created based on the latency to the first problem behavior. Subsequent functional analyses confirmed the predictive value of the hierarchy, with shorter latency demands consistently producing more differentiated functional analysis outcomes.
几乎没有直接评估程序旨在识别潜在的负强化物（例如，在功能分析的逃避条件中包括要求）。两名参与者被系统地暴露于照顾者提名的一系列潜在负强化物的要求下。在首次出现问题行为后，治疗即结束，并根据首次出现问题行为的潜伏期创建了一个需求厌恶层级。随后的功能分析证实了该层级的预测价值，较短的潜伏期需求始终产生更具区分性的功能分析结果。
