Uncertainty in learning and decision-making: Introduction to the special issue.

Uncertainty is a fundamental aspect of the environment. This special issue presents interdisciplinary research on decision-making and learning under uncertainty. Thirty-one research and review papers report the findings of the behavioral, neural, and computational bases of coping with uncertainty, as well as changes of these mechanisms in development, aging, and psychopathology. Taken together, this special issue presents extant research, identifies gaps in our knowledge, and offers paths for future directions.
