“…Elementary forms of cognitive grasping of these principles might be available at early stages in the development of human cognition (e.g., Baillargeon, 2001;Spelke, 1990), with a more explicit understanding of them emerging in adult sensorimotor skills (Ballard, Hayhoe, Pook, & Rao, 1997;Gibson, 1979;Noë, 2004) and adult 'folk physics' (McCloskey, 1983;McCloskey, Caramazza, & Green, 1980). On the other hand, humans can also interact with and reason about existing, dead or fictional animated 6 and intentional agents-i.e., animated creatures to whom we ascribe intentional states such as beliefs, desires and intentions (e.g., Astuti, 2001;Bloom, 2002Bloom, , 2004Bonatti, Frot, Zangl, & Mehler, 2002;Dennett, 1971Dennett, , 1987Koenig, Clément, & Harris, 2004;Malle, Moses, & Baldwin, 2001;Puccetti, 1968). In order to account for the behavior of such agents we need to add principles not reducible to those used to track physical objects.…”
