The first purpose of this study was to attempt to replicate previous findings that video-based preference assessments without access to selected stimuli may accurately predict relative reinforcing efficacy of stimuli. To do this, we conducted a concurrent operant reinforcer assessment in which we evaluated the relative reinforcing value of highly preferred and less preferred items identified in a video-based preference assessment. The second purpose of this study was to begin to evaluate the potential behavioral mechanisms responsible for the validity of this assessment. To conduct this analysis, we evaluated the relative reinforcing value of those same stimuli depicted in video format and then compared results to results obtained during the reinforcer assessment for tangible stimuli. For all five participants, stimuli identified as highly preferred functioned as reinforcers, and four of five participants, responding during the reinforcer assessment was similar in the presence of tangible stimuli and videos depicting those stimuli.
本研究的首要目的是尝试复制先前的研究结果，即不接触选定刺激物的基于视频的偏好评估可能准确预测刺激物的相对强化效力。为此，我们进行了一项同时进行的操作性强化评估，评估了在基于视频的偏好评估中确定的高偏好和低偏好项目的相对强化价值。本研究的第二个目的是开始评估导致这种评估有效性的潜在行为机制。为了进行这种分析，我们评估了以视频形式呈现的相同刺激物的相对强化价值，然后将结果与在强化评估中获得的有形刺激物的结果进行比较。对于所有五名参与者，被确定为高度偏好的刺激物起到了强化物的作用，并且在存在有形刺激物和视频呈现这些刺激物的情况下，五名参与者中有四名的反应相似。
