Children acquire complex relational representations of the world. Explaining the acquisition of these representations has been a significant challenge for theories of cognitive development. Recent work suggests that two processes, theory revision and redescription, operate in an iterative, complementary fashion to produce new representations. Given a novel situation, children use theory revision to generate a candidate relational structure and can modify that structure in response to error. Redescription detects regularities created through successful use of that structure in interaction with the environment; these regularities are consolidated into new representations, which are then available to the theory revision process. The complementary nature of these processes is illustrated by recent work on representational change in a gear-system task and in arithmetic concepts. Theory revision and redescription occupy different, but mutually supportive, niches in knowledge acquisition.
