The impact of stimulus size and presentation on choice during a preference assessment was investigated using a modified multiple-stimulus without replacement (MSWO) technique. Stimuli were either presented with a uniform magnitude, as determined by mass, or in a manner consistent with caregiver report of reinforcer consumption. While both assessment procedures identified the same top three preferred items in three out of five cases, greater variability in the preference rank of less preferred items was observed between assessments.
使用改良的无替换多刺激（MSWO）技术，研究了刺激大小和呈现方式对偏好评估期间选择的影响。刺激要么以由质量决定的统一大小呈现，要么以与照顾者关于强化物消耗的报告一致的方式呈现。虽然两种评估程序在五分之三的案例中都确定了相同的前三项偏好项目，但在评估之间观察到较不偏好项目的偏好排名存在更大的变异性。
