Why do some people react more strongly than others when faced with the unknown? Researchers at EPFL’s Laboratory of Behavioral Genetics, headed by Professor Carmen Sandi, have set out to learn more with a new virtual reality program. Their system evaluates how users’ personality traits and prior experience influence their responses to anxiety-inducing situations. Designed to be tested on a large sample of volunteers, it will be available for visitors to try out during the Geneva International Film Festival on 5–10 November, where it will be featured in the Digital Out of Competition category.
