A paired-stimulus preference assessment was conducted for 6 individuals with developmental disabilities. We selected stimuli that were representatives of 4 categories: chocolate, salty and crunchy, gummy, and fruit and vegetable. For all 6 participants, at least 3 of the 5 most preferred items came from the same category. On subsequent reinforcer assessments, items from the highest ranked preference category, some of which were included in the preference assessments and some of which were not, functioned as reinforcers. These findings suggest that after categories of preferred items are identified, clinicians may be able to identify reinforcers for some individuals without conducting additional assessments.
对6名发育障碍患者进行了配对刺激偏好评估。我们选择了代表4类的刺激物：巧克力、咸脆食品、软糖以及水果和蔬菜。对于所有6名参与者来说，5个最偏好项目中至少有3个来自同一类别。在随后的强化物评估中，来自排名最高偏好类别的项目（其中一些包含在偏好评估中，一些则未包含）起到了强化物的作用。这些发现表明，在确定了偏好项目的类别之后，临床医生或许能够在不进行额外评估的情况下为一些个体确定强化物。
