Stiles-Davis proposes that the infants in our experiments (Hofsten & Spelke, 1985) did not reach for perceived objects in order to manipulate them, but rather touched perceived surfaces in order to explore their boundaries. Her commentary raises questions about infants' perception of the boundaries, the unity, and the manipulability of objects. More deeply, it raises the question of what an object is for an infant. We consider each of these questions in turn, in light of our own findings and those of other studies of object-directed reaching, object perception, and the object concept. We suggest that young infants organize the visual world into entities that are bounded, unitary, and manipulable and that infants endow those entities with the core properties of physical objects.
斯泰尔斯 - 戴维斯提出，我们实验中的婴儿（霍夫斯坦 & 斯佩尔克，1985）伸手去够被感知到的物体并非为了操控它们，而是触摸被感知到的表面以探索其边界。她的评论引发了关于婴儿对物体边界、整体性和可操控性的感知的问题。更深入地说，它提出了对于婴儿而言一个物体是什么的问题。我们根据自己的研究发现以及其他关于目标导向伸手动作、物体感知和物体概念的研究，依次考虑这些问题。我们认为，年幼的婴儿将视觉世界组织成有边界、统一且可操控的实体，并且婴儿赋予这些实体物理物体的核心属性。
