Metacognition, the ability to assess one?s own knowledge, has been targeted as a critical learning mechanism in mathematics education. Yet, the early childhood origins of metacognition have proven difficult to study. Using a novel nonverbal task and a comprehensive set of metacognitive measures, we provide the strongest evidence to date that young children are metacognitive. We show that children as young as 5 years make metacognitive ?bets? on their numerical discriminations in a wagering task. However, contrary to previous reports from adults, children?s metacognition proved to be domain-specific: children?s metacognition in the numerical domain was unrelated to their metacognition in another domain (emotion discrimination). Moreover, children?s metacognitive ability in only the numerical domain predicted their school-based mathematics knowledge. The data provide novel evidence that metacognition is a fundamental, domain-dependent cognitive ability in children. The findings have implications for theories of uncertainty and reveal new avenues for training metacognition in children.
