Déjà vu literally means, “already seen” in French, it is a mental psychological phenomena in which a person feels like the event or experience they are currently involved in has happened before. Déjà vu is a very simple concept to grasp, one could be entering a room or encountering an object they have not seen before and immediately be flooded with feelings of familiarity and experience. This psychological phenomena is fairly common with individuals, in a study where fifty people were asked to take a survey, two thirds of them reported having experienced at least one déjà vu experience, and of these participants, they “typically” reported experiencing déjà vu more than once (Brown, 2004.) Déjà vu has long been shrouded in mystery and not many people throughout time have been aware of what déjà vu actually is, they usually just accept it as a weird or inappropriate feeling and then move on with daily life. As time goes on and psychology becomes more and more contemporary, research and studies of déjà vu have been able to shed some light on the mysterious (but harmless) mental phenomena.
Edward Titchener, a psychologist heavily credited with bringing the concept of “structuralism” to the United States, touched on the subject of déjà vu in his 1928 book, A Textbook of Psychology. In his book he explained that déjà vu is not a precognition or a psychic prediction but rather a glitch in a memory, which gives people experiencing the phenomena the false belief that the event had previously occurred. Titchener described déjà vu as a person having a “brief glimpse” of an event/object/situation before the brain has fully constructed a memory of said event/object/situation. It has been thought that déjà vu is caused by the brain’s short term and long term memory overlapping, or mixing together, which makes the person believe that the recent event took place further back in time than it actually did.
Déjà vu decreases as people get older (Brown, 2004) and usually is very...
