“…Babies believe that agents are distinct from objects in that they can move without contact (Spelke, Phillips, & Woodward, 1995) and act in certain ways in response to goals (Woodward, 1998;Gergely & Csibra, 2003). Confronted with evidence that children's behavior is restricted in predictable ways, the natural response is to hypothesize the existence of innate constraints, including the whole object constraint (Markman, 1990) core systems of object representation, psychology, physics, and biology (Carey & Spelke, 1996;Spelke & Kinzler, 2007;Carey, 2009), and so on. Given that they appear so early in development, it seems sensible to postulate that these constraints are innate rather than learned.…”
