The course introduces an interdisciplinary approach that combines methods of cognitive psychology, psychophysics and neuroscience with experimental economics and game theory to provide an exhaustive description of individual decision-making. The aim of the course is to illustrate how the study of decision-making processes, and more generally the functioning of the mind, can help understand the dynamics of individual economic choices. The course also has the objective of transmitting to the student a general knowledge of the most advanced research techniques in the field of psychophysics, decision psychology and experimental economics.
