在这个实验中，我们研究了10个月大的婴儿是否对物体内部的相关性敏感，以对有生命的物体进行分类。使用对象检查范式，10个月大的婴儿（N = 58）熟悉具有不同外观但共享内部的新物体，分为三组：无线索，眼睛和线索控制。在测试过程中，向婴儿展示一个新的类别内测试对象，然后是一个类别外测试对象。当物体带有动画提示（如眼睛）时，婴儿将物体分类在一起。相比之下，当物体在没有任何附加线索的情况下被呈现，或者当它们被呈现时有一个共同的感知标记（线索控制，即，把塑料勺子放在物体上面），婴儿没有表现出分类的证据。这些结果表明，到10个月大的时候，眼睛向婴儿发出信号，表明物体具有某种共同之处，这种共同之处可能不明显，也不容易感知到。
In this experiment, we examined whether sensitivity to the relevance of object insides for the categorization of animate objects is in place around 10 months of age. Using an object examining paradigm, 10-month-old infants' (N = 58) were familiarized to novel objects with varying outward appearances but shared insides in one of three groups: No cues, Eyes, and Cue control. During test trials, infants were presented with a novel in-category test object followed by an out-of-category test object. When objects were presented with animacy cues (i.e., Eyes), infants categorized the objects together. In contrast, when objects were presented without any added cues or when they were presented with a shared perceptual marker (Cue control, i.e., plastic spoons placed on top of the objects), infants showed no evidence of categorization. These results indicate that by 10 months of age, eyes signal to infants that objects share some kind of uniting commonality that may not be obvious or readily perceptually available.
