This chapter discusses the origins of Deja Vu and Jamevoo, proposing that they occur due to the misfiring of a familiarity signal in the brain and the subsequent evaluation of the experience. It also examines the connection between frequent Deja Vu and Jamevoo experiences and the ability to detect memory inconsistencies, while questioning whether Deja Vu is an error or a normal memory process.
There’s a sensation many of us might have experienced: when something routine or recognisable suddenly feels strange and unfamiliar. It’s known as jamais vu, or ‘never seen’. Research into this odd feeling recently won an Ig Nobel prize, which is awarded to science that makes you laugh, then think. Ian Sample speaks to Ig Nobel recipient Dr Akira O’Connor about why he wanted to study jamais vu, what he thinks is happening in our brains, and what it could teach us about memory going right, and wrong.
