Déjà Vu Phenomenon Theories Quiz

Déjà vu is a phenomenon where a situation feels familiar even though it is being experienced for the first time.

Over 40 theories

The dual processing theory suggests that a delay in information processing causes the brain to interpret late information as a separate event, leading to the feeling of déjà vu.

The hologram theory proposes that déjà vu occurs when the brain summons up an old memory without identifying it, creating a sense of familiarity without recollection.

The divided attention theory states that déjà vu happens when the brain subliminally records an environment while distracted by a particular object, making the situation feel familiar when attention returns.

The contradictory feelings of familiarity and novelty during déjà vu could arise from a dissociation or delay between different neural pathways responsible for processing familiarity and recollection.

The hologram theory suggests that during déjà vu, the brain retrieves fragmented memory traces or partial representations that create a strong sense of familiarity without providing full recollective details.

Experiments manipulating attentional load or measuring neural processing delays could potentially differentiate whether déjà vu arises from divided attention during encoding or asynchronous processing of familiarity and recollection signals.

Individuals with variations in attentional control, memory processes, or neural synchronization could potentially experience more or less frequent déjà vu episodes depending on how these factors impact the proposed mechanisms.

Alternative explanations could invoke factors like false memories, sleep/wake transitions, temporal lobe dysfunction, or other cognitive distortions. Evaluating them would require evidence discriminating proposed mechanisms from those of existing theories.
