Find out more about Dr Gaelle Vallee-Tourangeau


Gaelle is a cognitive psychologist specialising in the field of judgement and decision-making. She lectures on cognitive processes, (ie the mental processes underpinning communication, problem-solving and decision-making) and cognitive ergonomics (the study of how efficient people are in analysing, planning and making decisions in their work environment).

Says Gaelle: "On any given day, people are exposed to a large volume of information from a range of media. This proliferation of 'news' compound the sense that definite answers are few and far between. Yet often even where people do not know for sure what the case is, or what the future will bring, they must still act, make decisions, choose between alternatives, or sometimes simply communicate the uncertainty surrounding future outcomes."

She goes on to explain that ideally, we should be able to communicate and interpret risks objectively, reason appropriately with uncertain facts, make optimal and informed decisions based on information that is available to us, and make consistent choices based on our personal preferences.

But in reality, the communication of risks is often problematic, our reasoning under uncertainty can be flawed and our decisions and preferences can be swayed depending on our state of mind or the context in which they are made.

"Therefore better understanding of how we face and deal with uncertainty in our daily lives  is key to help us cope better with our modern environment," she adds.

"My research thus strives to contribute to the psychology of risk and uncertainty and the psychology of decision-making. My focus is on how individuals reason about, judge, communicate, or make decisions under uncertainty."

She currently acts as Associate Editor for the European Review of Applied Psychology (Elsevier) and is the director of the interdisciplinary Group for Decision, Thinking, and Risk research (iGDTR). She also works as a research consultant for Sanofi-Pasteur on issues related to the psychology of vaccination decisions.

 Her work has been published in such international journals as Cognition, Memory & Cognition, Acta Psychologica and Psychological Science.
