Jamais vu
Template:Short description Template:Use dmy dates Template:Italic title Template:WiktTemplate:About In psychology, jamais vu (Template:IPAc-en Template:Respell, Template:IPAc-en Template:Respell, Template:IPA), 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.
Overview
Jamais vu involves a sense of eeriness and the observer’s impression of experiencing something for the first time, despite rationally knowing that they have experienced it before.<ref name=":1">Template:Cite book</ref>
Jamais vu is commonly explained as when a person momentarily does not recognize a word or, less commonly, a person or place, that they already know.<ref name="study" /> Jamais vu is sometimes associated with certain types of aphasia, amnesia, and epilepsy.
Experiment
A study by Chris Moulin of Leeds University asked 92 volunteers to write out "door" 30 times in 60 seconds. 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.<ref name="study" />
Causes
Jamais vu can be caused by epileptic seizures.<ref>"Epilepsy and seizure information for patients and health professionals – Simple Partial Seizures", retrieved 2011-09-08</ref><ref name=":1" />
