我们如何判断世界上物体之间的相似性，最终与我们如何表现这些物体有关。人们普遍认为，人类的物体表征本质上是“结构化的”，这意味着个体特征和它们之间的关系都会影响相似性。相比之下，比较心理学中的流行模型认为，非人类物种只欣赏表面上的特征相似性。通过将结构和特征相似性的心理学模型（从连接特征模型到Tversky的对比模型）应用于成年人类、黑猩猩和大猩猩的视觉相似性判断，我们证明了对复杂结构信息的跨物种敏感性，特别是对结合颜色和形状的刺激。这些结果揭示了非人类猿类表征的复杂性，以及特征编码在解释物体表征和相似性方面的基本局限性，这在人类和非人类物种中都引人注目。
How we judge the similarity between objects in the world is connected ultimately to how we represent those objects. It has been argued extensively that object representations in humans are ‘structured’ in nature, meaning that both individual features and the relations between them can influence similarity. In contrast, popular models within comparative psychology assume that nonhuman species appreciate only surface-level, featural similarities. By applying psychological models of structural and featural similarity (from conjunctive feature models to Tversky's Contrast Model) to visual similarity judgements from adult humans, chimpanzees, and gorillas, we demonstrate a cross-species sensitivity to complex structural information, particularly for stimuli that combine colour and shape. These results shed new light on the representational complexity of nonhuman apes, and the fundamental limits of featural coding in explaining object representation and similarity, which emerge strikingly across both human and nonhuman species.
