Affect and decision making

Choices we make “in the heat of the moment” are often different from those we make while “cool and collected.” Examples include unsafe sex, impulse purchases and ill-considered online behaviour. We are examining the effects of emotional arousal on decision making across the adult lifespan using a multi-method experimental approach (behaviour, event-related potentials, eye tracking and pupillometry, and functional magnetic resonance imaging). We are also trying to understand how arousal effects observed in the laboratory relate to real-world decision quality. This line of research is supported by a Discovery Grant from the Natural Sciences and Engineering Research Council.
