The Smart Nonconserver : Preschoolers Detect Their Number Conservation Errors

Abstract EN

Classic developmental studies have established that children’s number conservation is often biased by misleading intuitions.

However, the precise nature of these conservation errors is not clear.

A key question is whether children detect that their erroneous conservation judgment is unwarranted.

The present study focuses on this critical error sensitivity issue.

Preschool children were given a classic version of a number conservation task in which an intuitively cued response conflicted with the correct conservation response and a control version in which this conflict was not present.

After solving each version children were asked to indicate their response confidence.

Results showed that in contrast with children who gave a correct conservation response, preschoolers who erred showed a sharp confidence decrease after solving the classic conflict problem.

This suggests that nonconserving preschoolers detect that their response is questionable and are less ignorant about conservation than their well-documented errors might have previously suggested.
