The JDM Lab takes a joint experimental and computational modeling approach to study human judgment, decision-making, and reasoning. We study how people make decisions when faced with multiple, complex alternatives and options involving different risks and rewards. For example, it is well documented that context can influence choices. This type of influence can have both positive and negative consequences. Most of us recognize that a store's design influences what products we buy, or how much we spend. Our lab uses computational models to investigate how we make decisions and how we can improve these decisions.

Research Highlight
Every day, people face snap decisions when time is a limiting factor. In addition, the way a problem is presented can influence people's choices, which creates what are known as framing effects. In work recently published in Psychological Science, we explored how time pressure interacts with framing effects in risky decision-making. Results showed increased framing effects under time pressure in both hypothetical and incentivized choices, which supports the dual-process hypothesis that these effects arise from a fast, intuitive system.
