When to decide not to decide: metacognition and uncertainty

In many tasks organisms choose actions based on an assessment of the value to them of possible outcomes (food, safety, etc.) and the probability associated with each possible outcome. Exactly how actions are chosen and how probability affects choice is a central question across many disciplines: biological foraging theory, systems neuroscience, economic decision making, perceptual psychology, and the planning of movement. We will focus on tasks in these disciplines where the organism has only imperfect knowledge of probability. Contrast, for example, betting on a fair coin where the probability of each outcome is known with betting on the occurrence of rain next Tuesday. There is a probability of rain next Tuesday but it unlikely to be known to you or anyone else. We examine, first of all, how well the organism knows its own uncertainty about probability (metacognition) and, second, how it assesses the value of information that could reduce uncertainty about probability: how much would you pay for a weather report for next Tuesday?
