抽象的。目前，灵长类动物的面部处理研究主要集中在少数几个物种上，主要是猕猴和黑猩猩;到目前为止，只有一种新大陆猴，松鼠猴，已经被测试过。我们探讨了面对处理，特别是反转效应，在新的世界灵长类动物物种，棉顶绢毛猴（Saguinus oedipus）。在我们研究的第一阶段，我们训练受试者区分两张脸和两张混乱的脸;然后我们向绢毛猴展示了一系列新颖的探针，以确定分类的基本特征。结果表明，绢毛猴对面部外部轮廓的依赖性大于对面部内部特征及其构造的依赖性。统计分析显示，准确性或反应时间直立与倒置刺激没有差异，因此没有倒置效应。在第二阶段，我们为受试者提供了额外的训练，在面对与混乱的脸歧视的任务，以集中他们的注意力在配置的内部功能。准确性数据揭示了绢毛猴如何分类这些刺激的个体差异，即使每个受试者都以相同的方式接受训练。在第3阶段，我们测试了一组新的面部刺激的泛化能力，以及显示反转效应的能力。对于一个参加内部特征配置的受试者，我们发现了泛化的重要证据，但没有反转效应的证据。
Abstract. Current research on face processing in primates has focused on a few species, mostly macaques and chimpanzees; to date, only one New World monkey, the squirrel monkey, has been tested. We explored face processing, and the inversion effect in particular, in a New World primate species, the cotton-top tamarin (Saguinus oedipus). In phase 1 of our study, we trained subjects to discriminate between two faces and two scrambled faces; we then presented the tamarins with a series of novel probes in order to determine the features underlying classification. Results showed that the tamarins relied on the external contour of the face for discrimination more than the internal features and their configuration. Statistical analyses revealed no differences in accuracy or response times to upright versus inverted stimuli, and thus no inversion effect. In phase 2, we provided subjects with additional training on the face versus scrambled face discrimination task in order to focus their attention on the configuration of the internal features. Accuracy data revealed individual differences in how tamarins classified these stimuli, even though each subject was trained in the same way. In phase 3, we tested for generalization to a new set of face stimuli, as well as for the capacity to show an inversion effect. For one subject who attended to the configuration of internal features, we found significant evidence of generalization, but no evidence for an inversion effect.
