In psychology, jamais vu (/ˌʒæmeɪ ˈvuː/ ZHAM-ay VOO, US: /ˌʒɑːm-/ ZHAHM-, French: [ʒamɛ vy]), a French loanword meaning "never seen", is the phenomenon of experiencing a situation that one recognizes in some fashion, but that nonetheless seems novel and unfamiliar.
[4] A study by Chris Moulin of Leeds University asked 92 volunteers to write out "door" 30 times in 60 seconds.
In July 2006, at the 4th International Conference on Memory in Sydney, he reported that 68 percent of volunteers showed symptoms of jamais vu, such as beginning to doubt that "door" was a real word.
Moulin believes that a similar brain fatigue underlies some symptoms of schizophrenia and Capgras delusion.
Moulin suggests that people with these conditions could be suffering from chronic jamais vu.
