为深度智力迟钝患者制定有效的培训计划仍然是在发育障碍领域工作的行为分析师面临的最大挑战之一。这一人群的一个重大进步是由Pace、Ivancic、Edwards、Iwata和Page（1985）开发的强化物评估程序，该程序包括反复向来访者呈现各种刺激，然后测量接近行为以区分偏好和非偏好刺激。这个程序的一个潜在的限制是，一些来访者在每次呈现时都一致地接近大部分或全部刺激，这使得很难区分这些刺激。在本研究中，我们使用并发操作范式来比较Pace等人（1985）的程序和一个修改后的程序，其中客户同时看到两个刺激，并且只允许接触到第一个刺激。结果表明，这种强迫选择刺激偏好评估导致了刺激之间更大的差异，并更好地预测了在并发操作范式中偶然呈现的刺激会导致更高水平的反应。
The development of effective training programs for persons with profound mental retardation remains One of the greatest challenges for behavior analysts working in the field of developmental disabilities. One significant advancement for this population has been the reinforcer assessment procedure developed by Pace, Ivancic, Edwards, Iwata, and Page (1985), which involves repeatedly presenting a variety of stimuli to the client and then measuring approach behaviors to differentiate preferred from nonpreferred stimuli. One potential limitation of this procedure is that some clients consistently approach most or all of the stimuli on each presentation, making it difficult to differentiate among these stimuli. In this study, we used a concurrent operants paradigm to compare the Pace et al. (1985) procedure with a modified procedure wherein clients were presented with two stimuli simultaneously and were given access only to the first stimulus approached. The results revealed that this forced-choice stimulus preference assessment resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented contingently in a concurrent operants paradigm.
