Children adapt their information search to goal and statistical structure of a problem.

To be efficient, problem solvers need to be adaptive, tailoring their information search to the specific problem at hand. Across two studies, we investigated the emergence and early development of children's ability to adapt their information search to a given goal (Studies 1 and 2) and to the statistical structure of the problem space (Study 2) to maximize effectiveness. In Study 1, 3-6-year-olds (
