Definition

Noun: A psychological phenomenon involving the subjective feeling of unfamiliarity or strangeness towards a situation, person, or place that one knows rationally to be very familiar. It is the opposite of déjà vu and is sometimes associated with certain neurological conditions, such as temporal lobe epilepsy.

Usage

The term is used primarily in psychological, neurological, and literary contexts to describe a specific type of cognitive dissonance where recognition fails. It is often contrasted with its opposite, déjà vu.

Examples

• He experienced a sudden and unsettling jamais vu when looking at his own handwriting; for a moment, it seemed completely alien to him.
• The psychologist explained that jamais vu, while disorienting, is a known phenomenon where a familiar face can momentarily seem like that of a stranger.
• In the novel, the protagonist's sense of jamais vu in her childhood home symbolized her profound emotional disconnect.

Advanced Usage

• Clinical Context: In neurology, frequent episodes of jamais vu can be a diagnostic indicator for seizure activity, particularly in the temporal lobe.
• Linguistic Context: A speaker may experience jamais vu with a common word, staring at it until it loses its meaning—a phenomenon sometimes called "semantic satiation."

Variants and Related Words

• Déjà vu (n.): The illusion of remembering scenes and events when experienced for the first time; a feeling of familiarity.
• Presque vu (n.): The intense feeling of being on the brink of an epiphany or recall, often called the "tip-of-the-tongue" phenomenon.
• Capgras delusion (n.): A more severe and persistent psychiatric disorder involving the belief that a familiar person has been replaced by an impostor, distinct from the transient feeling of jamais vu.
