这项研究的主要目的是验证不同的社会环境是否会影响普通绒猴对新食物的反应。这个问题在涉及四个社会群体的三个测试中进行了测试。关于对新奇食物的反应的数据是从总共8名食物天真的年轻人那里收集的。特别是，与只允许视觉接触的情况相比，我们探索了食物初学者和有经验的人之间的直接接触是否会对第一种新食物的反应产生不同的影响。然后将这两种不同的社交环境与另一种情况进行比较，在这种情况下，对新奇食物的反应不是通过小组成员的经历来调节的。结果显示，与对照测试相比，在社交环境中观察到幼崽进食的间隔时间明显更长。然而，这一结果只在新食物的情况下得到证实，而不是在熟悉的食物的情况下。此外，在允许直接社会接触的测试中，天真的年轻人从小组成员那里获得食物的频率在新奇食物的情况下明显多于熟悉的食物。这项研究表明，尽管天真的幼崽在结对时，不需要观察有经验的小组成员或与有经验的小组成员互动，但他们对新食物的反应很快，但社交促进的过程是显而易见的。在熟悉的食物中没有观察到这样的过程，证实了这样的假设，即从长远来看，社会促进的作用是为了在群体的饮食中获得新的食物。
The main aim of this study was to verify if the response to novel foods in common marmoset (Callithrix jacchus) is influenced by different social settings. This question was tested in three tests involving four social groups. The data regarding the response to novel foods were collected from a total of eight food-naive young. In particular, we explored if direct contacts between food-naive and experienced individuals would have a different effect on the response to novel food by the first, in comparison with a situation in which only visual contacts were allowed. These two different social settings were then compared to a situation in which the response to novel food was not mediated by the experience of group-mates. The results showed a significantly higher number of intervals in which naive young, in social settings, were observed feeding compared with a control test. However, this result was confirmed only in the case of novel foods, not in the case of familiar foods. Furthermore, in the tests in which direct social contacts were allowed, naive young obtained food from group-mates significantly more often in the case of novel than familiar foods. This study suggests that although naive young, when left in pairs, responded quickly to novel foods without the need to observe or interact with experienced group-mates, a process of social facilitation was evident. Such a process was not observed in the case of familiar foods, confirming the hypothesis that social facilitation operates in order to acquire novel foods in the diet of the group in the long term.
