A four-phase investigation was completed to analyze the utility of forced-choice preference assessments when response effort and reinforcer delays are altered within a subsequent reinforcer assessment. The results indicated that access to highly preferred stimuli continued to serve as a reinforcer when increased response effort was required. When reinforcer delay was increased, the utility of preferred stimuli to serve as a reinforcer was variable. Despite stimuli continuing to serve as reinforcers for academic task engagement, increased response effort and reinforcer delay resulted in an increased level of aberrant behavior.
完成了一项分为四个阶段的调查，以分析在后续强化物评估中改变反应努力和强化物延迟时，强制选择偏好评估的效用。结果表明，当需要增加反应努力时，接触高度偏好的刺激物继续作为一种强化物。当强化物延迟增加时，偏好刺激物作为强化物的效用是可变的。尽管刺激物继续作为学术任务参与的强化物，但反应努力和强化物延迟的增加导致了异常行为水平的提高。
