Uncertainty in perceptual decision-making

Abstract: Whether we are judging traffic in foggy conditions, estimating a ball’s trajectory when playing tennis, or interpreting radiological images to diagnose and treat disease – virtually every choice we make is based on uncertain evidence. How do we infer that information is more or less reliable when making these decisions? How does the brain represent knowledge of this uncertainty? In this talk, I will present recent neuroimaging data combined with novel analysis tools to address these questions. Our results indicate that sensory uncertainty can reliably be estimated from the human visual cortex on a trial-by-trial basis, and moreover that observers appear to rely on this uncertainty in their perceptual decision-making.
