Jamais Vu Is The Opposite of Deja Vu

Jamais vu, the oppostite of "deja vu," means "never seen" in French. It refers to the feeling that one has never seen before something that should be very familiar, like when you look at a common word for so long that it suddenly seems meaningless or strange. Dr. Chris Moulin, a researcher from the UK, estimated that 60% of people have experienced the sensation in their lifetimes. He was able to induce the feeling in a study by having subjects write simple words over and over. Learn more about jamais vu—and its sibling, deja vu—in the videos below.
