目前的研究调查了12.5个月大的婴儿在解释代理人的行为时是否考虑到代理人知道出现在场景中的物体。在两个实验中，婴儿们看到一名女性人类特工反复伸手抓住器械地板上的物体A，而不是物体B。物体B可以(1)通过透明的屏蔽物被代理人看到；(2)通过不透明的屏蔽物对代理人(但不是婴儿)隐藏；或者(3)由代理人自己放在不透明的屏蔽物后面，这样即使她不能再看到物体B，她也知道它的存在。婴儿将代理人对对象A的重复动作解释为，只有当她在场景中看到对象B(1)或意识到它的存在时，才显示出对对象A的偏好。这些结果表明，当观看代理对场景中的对象进行操作时，12.5个月大的婴儿会跟踪代理对这些操作发生的物理环境的表征。如果代理人的表征是不完整的，因为代理人对环境的某些方面一无所知，婴儿就会使用代理人的表征，而不是他们自己更完整的表征来解释代理人的行为。(C)2006爱思唯尔B.V.保留所有权利。
The present research examined whether 12.5-month-old infants take into account what objects an agent knows to be present in a scene when interpreting the agent's actions. In two experiments, the infants watched a female human agent repeatedly reach for and grasp object-A as opposed to object-B on an apparatus floor. Object-B was either (1) visible to the agent through a transparent screen; (2) hidden from the agent (but not the infants) by an opaque screen; or (3) placed by the agent herself behind the opaque screen, so that even though she could no longer see object-B, she knew of its presence there. The infants interpreted the agent's repeated actions toward object-A as revealing a preference for object-A over object-B only when she could see object-B (1) or was aware of its presence,in the scene (3). These results indicate that, when watching an agent act on objects in a scene, 12.5-month-old infants keep track of the agent's representation of the physical setting in which these actions occur. If the agent's representation is incomplete, because the agent is ignorant about some aspect of the setting, infants use the agent's representation, rather than their own more complete representation, to interpret the agent's actions.
