The understandings of language acquisition and of cognitive structures are in debate in the center of the cognitive sciences. It happens despite of a group of academics who, in a rhetorical way, insists on despising Piaget's constructivist model, keeping a connection to Chomsky's innatist theory. This paper recalls the classical debate between these two knowledge systems, rethinking it in a psychobiological perspective and presenting recent neurobiological studies that suggest a correction of commitment between innate and acquired as pointed by Piaget.
