How do humans navigate uncertainty, continuously making near-effortless decisions and predictions even under conditions of imperfect knowledge, high complexity, and extreme time pressure? What are the specific decision making deficits among people with addiction and how can we use them to develop treatment procedures that help people overcome these deficits? How do police officers in a situation full of uncertainty and facing the most severe consequences decide to shoot? Research in our lab uses computational modeling to investigate these questions as well as others within the realm of behavioral economics and cognitive science.
