使用支持问题测试了普通绒猴对物理因果关系的理解，在支持问题中，呈现了一对表，以确定受试者是否会选择上面有食物的表（即，片材支撑食品）。在两个实验中，根据片材的长度、片材与食品之间的距离、分隔两个片材的间隙的存在以及食品的尺寸来操纵条件。在实验1中，绒猴很难拒绝一个不可挽回的食物时，它位于更接近他们比一个可检索的项目。虽然他们的表现受到无法收回的食物的大小的强烈影响，但他们很快学会了拒绝这种替代品。相比之下，当一个片材被分成两片使得当拉动食品的近侧时不能取回食品时，没有发现改善。在实验2中观察到类似的反应趋势，在实验2中，在三种不同的条件下检查大的食物项目的影响。因此，普通绒猴在解决支持问题时会受到食物的感知特征的影响，其他非人类灵长类动物也是如此。此外，他们始终没有意识到存在的差距，因此，未能拒绝分心的替代品。然而，所有的动物很快就学会了食物的大小是一个无关的变量，有些动物表现出对支持的基本概念理解。这些发现表明，绒猴的身体理解能力可能会随着经验的增加而提高。
The understanding of physical causality in common marmosets was tested using support problems in which a pair of sheets was presented to determine whether subjects would choose the sheet that had a food item on it (i.e., the sheet was supporting the food item). In two experiments, the conditions were manipulated in terms of the length of the sheet, the distance between the sheet and the food item, the presence of a gap separating the two sheets, and the size of the food item. In Experiment 1, the marmosets had difficulty rejecting an irretrievable food item when it was located closer to them than a retrievable item. Although their performance was strongly affected by the size of the irretrievable food item, they quickly learned to reject that alternative. In contrast, no improvement was found when one sheet was divided into two pieces such that the food item could not be retrieved when its near side was pulled. A similar response tendency was observed in Experiment 2, in which the effects of the large food item were examined in three different conditions. Thus, common marmosets were influenced by the perceptual features of the food in solving the support problems, as are other non-human primates. In addition, they consistently failed to appreciate the presence of a gap and, therefore, failed to reject the distracter alternative. However, all animals rapidly learned that the size of the food item was an irrelevant variable, and some showed an elementary conceptual understanding of support. These findings suggest that marmosets’ physical understanding may improve with experience.
