Our research uses the bounded rationality approach, which explores how organisms with limited time, information, and computational abilities make adaptive decisions. We use theoretical, experimental, and comparative methods to model and empirically investigate the cognitive processes organisms use when making decisions. One of our research topics explores the cognitive mechanisms, such as patience and accurate memory, needed to implement decision strategies in cooperative situations. Another research topic develops and tests process-based models of intertemporal choice. We also investigate questions of risky choice, quantification, timing, memory, and social networks to help understand how humans and other animals make decisions in an uncertain world.
