Abstract

We evaluated behavior exhibited by individuals with developmental disabilities using progressive-ratio (PR) schedules. High- and low-preference stimuli were determined based on the results of a paired-stimulus preference assessment and were evaluated in subsequent reinforcer and PR assessments using concurrent and single schedules of presentation. In Experiment 1, results showed that for 2 of 3 participants, stimuli determined to be low-preference functioned as reinforcers when evaluated independent of high-preference stimuli. Further, the results from Experiment 2 showed that low-preference stimuli also functioned as reinforcers under gradually increasing PR requirements. Results suggest that for cases in which a high-preference stimulus is unavailable or impractical, the contingent delivery of relatively less preferred stimuli may maintain appropriate behavior, even as schedule requirements increase.

摘要

我们使用渐进比率(PR)程序评估了发育障碍个体表现出的行为。根据配对刺激偏好评估的结果确定高偏好和低偏好刺激,并在随后的强化物和PR评估中使用同时呈现和单一呈现程序进行评估。在实验1中,结果表明,对于3名参与者中的2名,被确定为低偏好的刺激在独立于高偏好刺激进行评估时起到了强化物的作用。此外,实验2的结果表明,在PR要求逐渐增加的情况下,低偏好刺激也起到了强化物的作用。结果表明,在高偏好刺激不可用或不切实际的情况下,即使程序要求增加,相对不太偏好的刺激的偶然呈现也可能维持适当的行为。
