Questions and Answers

What is déjà vu?

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

How many theories attempt to explain déjà vu?

Over 40 theories

What is the dual processing theory of déjà vu?

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.

Describe the hologram theory of déjà vu.

<p>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.</p> Signup and view all the answers

What is the divided attention theory of déjà vu?

<p>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.</p> Signup and view all the answers

What neurological processes might underlie the contradictory feeling of familiarity and novelty experienced during déjà vu?

<p>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.</p> Signup and view all the answers

How might the hologram theory account for the vivid, yet elusive, sense of recollection during déjà vu experiences?

<p>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.</p> Signup and view all the answers

What experimental evidence might help distinguish between the divided attention and dual processing accounts of déjà vu?

<p>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.</p> Signup and view all the answers

How might individual differences in cognitive abilities or neurological functioning influence susceptibility to déjà vu experiences?

<p>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.</p> Signup and view all the answers

What alternative explanations beyond the presented theories could account for déjà vu phenomena, and how might they be evaluated?

<p>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.</p> Signup and view all the answers

What is Déjà Vu?

The feeling of familiarity in a new experience.

Dual Processing Theory

Delay in brain processing interprets late information as a separate event, creating familiarity.

Hologram Theory

Brain summons old memory without identifying it, causing familiarity without recognition.

Divided Attention Theory

The brain records environment while distracted. The situation feels familiar when attention returns.

Study Notes

  • Déjà vu is a phenomenon where a situation feels familiar even though it is being experienced for the first time.
  • There are over 40 theories attempting to explain déjà vu, with recent advancements in neuroimaging and cognitive psychology helping to narrow down possibilities.
  • Three prevalent theories include dual processing, which 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.
  • 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.
