Childhood unpredictability and the development of exploration

Proceedings of the National Academy of Sciences, 2023
Early in development, the process of exploration helps children gather new information that fosters learning about the world. Yet, it is unclear how childhood experiences may influence the way humans approach new learning. What influences decisions to exploit known, familiar options versus trying a novel alternative?
