Children's understanding of belief and disconfirming visual evidence

Data from 3- to 5-year-old children show that even the youngest have an understanding that a story character cannot think an object is in a box when the character looks into the empty box. This understanding is, however, limited to the case where children share the same visual perspective with the character. When visual perspectives are different the relevant knowledge develops shortly after 4 years at about the time that children master the false belief task. These results are interpreted as young children using an implicit constraint that “think” cannot be applied in view of disconfirming visual evidence. This implicit knowledge becomes explicit and, thus, perspective independent with some delay.
