Prior to coming to City, University of London, Dr Reimers held postdoctoral positions at Warwick and UCL, most recently, a fellowship from the ESRC Centre for Economic Learning and Social Evolution.

Dr Reimers is interested in high-level cognition, in particular judgement and decision making. One particular interest is in the psychology of time - how humans and other animals represent and make decisions involving time, in particular how and why people's discounting of delayed rewards varies across individuals and contexts.

Research interests

Other judgement and decision making interests include forecasting - how individuals and organisations can improve the predictions they make about future trends - and game theory - in particular, individual and contextual differences in strategies used for ultimatum, prisoner's dilemma and co-ordination games.

He also works on applying experimental psychology to policy issues, particularly the notion of what constitutes a 'fair' taxation structure. Further afield, Dr Reimers does work on executive control, cognitive ageing, sex differences and cerebral lateralisation.

He has wider interests in psychology, working regularly with the BBC and independent production companies on brain-science-related TV shows, and helping set up fun - yet valid - web-based psychology tests for the BBC website among other places. He also undertakes consultancy projects, examining consumer behaviour and the effects of interventions for major retailers and government departments.

Dr Reimers also has interests in using new technology in psychological research, extending from web-based research through running experiments on mobile phones, to work using Wii input devices - Balance Boards, accelerometers and the like - for recording behavioural data.

To see some of Dr Reimer's current web-based experiments, and to contribute to ongoing research, please see here.
