Deja Vu, the "already seen"

By: Landry Turner

Why I chose Deja Vu

I chose deja vu because I'm always experiencing it, but I know nothing about it. I think deja vu is interesting because its like a flashback to something that hasn't happened yet. By researching this topic it might help me understand deja vu and what it is and why it happens. It could also help others by really understanding whats going on.

DÉJÀ VU- "Already Seen"

What is Deja Vu?

Deja Vu is French for "already seen", which is pretty straight forward of what deja vu is. Deja vu is the feeling of familiarity of something that shouldn't really be familiar. For example, you could be having a conversation but then get the feeling that you've already had this conversation before.

The Brain during Deja Vu

Scientists have not exactly figured out whats going on in the brain during deja vu, but they have ideas. Remembering requires familiarity and recollection, so when these cooperating processes get in sync, we receive the feeling that we've experienced a moment that we really haven't experienced.

Over the years, scientists have blamed our temporal lobe as what can create deja vu. Researchers also found that the synchronized neural firing between the rhinal cortices and the hippocampus can induce deja vu.

As expected, theres many interesting theories have over deja vu. Some people believe that deja vu occurs when two universes become one. Then theres others who believe deja vu is involved with time travel or the thought that they might be psychic.

Research and Experiments

A common experiment thats tested tests familiarty-based recognition in which a group of volunteers were given a list of celebrity names. Later, the volunteers were then shown photos of celebrities, and on some photos had their names. The volunteers then had to identify the celebrities in the photographs and then indicate how likely it was that the names used on the photos were also used on the list of celebrities. Most of the volunteers were unable to identify them, which showed that they could store little memory, but it was too hazy to connect it to a new experience.

A psychologist named Anne M. Cleary studies deja vu, and even wrote a book about her recent findings over it called "Current Directions in Psychological Science".
