  Piaget’s theories provided the scientific received view against which developmentalists inspired by Chomsky’s linguistics reacted. These researchers set aside Piaget’s assumption that development is uniform across domains, and instead—in part inspired by Chomsky’s organology and modularity claims—considered each domain independently. The overall strategy was to discover the cognitive capacities of the youngest children, and to develop and test hypotheses about (i) the initial state, and (ii) the transitions that move the child from the initial state to the normal adult repertoire.
