  A very recent study has shown that infants are sensitive not only to clues indicating an agent’s capacity for autonomous motion, but to the perceptual information available to the agent as well and to the agent’s preferences. Remarkably, this is true even when this information differs from their own. In Luo and Johnson (2009), 6-month-old babies saw another person look at 2 different objects and repeatedly reach for the same one. As indicated by their looking times, babies in this condition attributed to the other person a preference for the chosen object.  In contrast, in a condition where the baby saw 2 objects, but also saw that the other person could see only one, no preference was attributed. In this case, it seems, the baby appreciates that the other person cannot see the second object and that therefore the repeated grasping of the first object does not indicate a preference. This suggests that babies at this age can already attribute different perceptual information to different perceivers (what I see vs. what she sees). Nativists expect to find similar sorts of perceptual preparedness for other systems of knowledge and action (for instance, a system of face recognition as preparedness for social and family life).
