"I Want to Know More!": Children Are Sensitive to Explanation Quality When Exploring New Information.

When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven- to ten-year-olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application.

"Is it worth my time and effort?": How children selectively gather information from experts when faced with different kinds of costs.

Gathering good-quality information is important for effective learning, but children may often need to expend time or energy (i.e., costs) in order to do so.

Children's success at detecting circular explanations and their interest in future learning.

These studies explore elementary-school-aged children's ability to evaluate circular explanations and whether they respond to receiving weak explanations by expressing interest in additional learning. In the first study, 6-, 8-, and 10-year-olds (n = 53) heard why questions about unfamiliar animals. For each question, they rated the quality of single explanations and later selected the best explanation between pairs of circular and noncircular explanations.
