Escape From Metaignorance: How Children Develop an Understanding of Their Own Lack of Knowledge
Child Development, 08/20/2012
Rohwer M et al. – Previous research yielded conflicting results about when children can accurately assess their epistemic states in different hiding tasks. In Experiment 1, ninety–two 3– to 7–year–olds were either shown which object was hidden inside a box, were totally ignorant about what it could be, or were presented with two objects one of which was being put inside (partial exposure). Even 3–year–olds could assess their epistemic states in the total ignorance and the complete knowledge task. However, only children older than 5 could assess their ignorance in the partial exposure task. In Experiment 2 with one hundred and one 3– to 7–year–olds, similar results were found for children under 5 years even when more objects were shown in partial exposure tasks.
