Tangible preference assessments were compared with verbal preference assessments for 6 individuals with mental retardation, behavior disorders, or both. In the tangible assessment, items were placed in front of the participant. In the verbal assessment, participants were asked, "Do you want X or Y?" and the items were not present. The two assessments yielded similar high-preference items for 4 of the 6 participants. The verbal assessment was typically completed in less time than the tangible assessment.
对6名患有智力障碍、行为障碍或两者皆有的个体进行了实物偏好评估与言语偏好评估的比较。在实物评估中，物品被放置在参与者面前。在言语评估中，会问参与者：“你想要X还是Y？”，且物品并不呈现。对于6名参与者中的4名，两种评估得出了相似的高偏好物品。言语评估通常比实物评估完成得更快。
