This website provides information on the work being conducted by the Geary Institute and the School of Psychology in NUI Maynooth. The aim of this work is to explore the biological processes underlying human decision-making in different domains of life.  The work utilises electrophysiological measurement techniques to examine how participants' brains react to the presentation of rewards that differ along dimensions such as the level of delay, the type of reward, the degree of risk and magnitude of reward. We aim to develop and test theories of intertemporal choice and to apply these theories to applied contexts, particularly in the areas of health and financial decision making.
