How do emotions affect financial decisions? Is their impact always bad, or are emotions an important part of making good financial decisions? Can a better understanding of emotion help us avert future financial crises? These are some of the questions being asked by the xDelia project: a European Commission funded research programme being conducted by The Open University and other partners. The project is using leading edge physiological sensors and computer game technologies to explore the impact of emotions on financial decision-making and to develop new approaches to learning, which can support effective choices. In this podcast Professor Mark Fenton-O'Creevy of The Open University Business School looks at the work of this research programme and explores the ways in which emotions affect how we all (from investment bankers to the wider public) think and decide about money. xDelia is funded by the European Commission under the 7th Framework Programme.
