Our environment is both complex and changing, which triggers uncertainty in every decision we make. The ability to detect and solve the resulting uncertainty is crucial for adapted and flexible behavior. Our hypothesis is that behavioral efficiency and flexibility in an uncertain environment depend on the way the agent has learnt to learn. In a first study, 3 macaque monkeys developed a learning-set for a task with stochastic and changing rules. Monkey’s reactivity to unexpected feedback increased across learning and paralleled the evolution of the degree of environmental uncertainty. This enabled them to transfer, without cost, to a more complex task with the same structure, suggesting that they learned to learn the statistical structure o...
