what are the psychological and physiological factors that cause Jamais Vu?

Answer 1

Not my field but this is what I found: Clinically, Jami's vu is used for a moment of perceptual disconnection from memory when the familiar seems unfamiliar. One loses one’s past in the eternal now and all seems new. It is a mystical moment of temporal anomaly or temporary amnesia.

In it’s psychological usage Jami's Vu is defined by using it’s partner déjà vu as a referent but the concept can stand and be defined on it’s own in a broader context on the world stage.

The term Jamais Vu was coined by an American, Joseph Heller, in his break-out novel Catch-22. In fact the way that the word is used in terms of the group mind is that it is a NOVEL EVENT, the completely original, unprecedented and hence, unpredictable circumstance. the FIRST GLIMPSE of what may later be copied or imitated but a Jamais Vu Event can never be repeated, it is the anti-thesis of Déjà vu!
Not sure if this is what you where looking for but hope it helps....thank you

Answer 2

Jamais vu usually occurs as a form of amnesia from some trauma to the brain. I think that most common form is from alcoholism. I once met a person with severe alcoholism at an institution for people with mental illness. I used to give him a cigarette when I saw him. I would light the cigarette. He would aways ask, "What's your name? Nice weather we are having." The he would turn away scanning the room. Then he would face me again, act very surprised, and say, "Hello. What's your name? Nice weather we're having." Just an anecdote to demonstrate the point. He acted like he never saw me before and he would do the same thing as long as I sat there.

Answer 3

Jamais vu, presque vu and deja vu may be associated with seizure or migrane. Seems to originate from the temporal lobe of the brain.

Answer 4

By this do you mean I never saw it even though it was right there? We can have strong beliefs and decide not to challenge them and not see truth. Reason is ...when beliefs are challenged and proved wrong our brain tries to erase them and we get depression chemicals in our fluid. When the medulla has the depression chemicals affecting it ... the heart breathing, balance, temperature etc are affected. We call it being depressed.
