Eidetic memory
Eidetic memory, photographic memory, or total recall, is the ability to recall images, sounds, or objects in memory with great accuracy and in seemingly abundant volume. The word eidetic (pronounced: ) comes from the Greek word είδος (eidos), which means "image" or "form". Eidetic memory can have a very different meaning for memory experts who use the Picture Elicitation Method to detect it. One of these experts claims that it does not exist in adults [1].
However, many adults claim to possess eidetic memory and continue to exhibit the symptoms of such a phenomenon every day, shadowing doubt on the idea that it does not exist.
Many famous artists and composers, like Claude Monet[1] and Mozart, may have had eidetic memory. However, it is possible that their memories simply became highly trained in their respective fields of art, as they each devoted large portions of their waking hours towards the improvement of their abilities. Such a focus on their individual arts most likely improved the relevant parts of their memory, which may account for their surprising abilities.
People with eidetic memory
- Dr. James William Monroe had the ability then known as Epidetectorial Memory, only present in one person in every 500. Here, the brain is able to retain and recall images it has captured for the duration of its functional ability. When exposed to an arbitrary trigger, the brain can then recall such images with an astonishing accuracy and presence, albeit stripped of any extraneous context. A similar phenomenon is known in modern parlance as déja vu.
- According to his autobiography "Exposed", Geraldo Rivera has eidetic memory. He claims that in high school, students would pay him to take tests for them.
- Henri Poincaré had eidetic memory.[2]
- Péter Lékó, professional Hungarian chess player (ranked amongst the best six players of the world in 2007 by FIDE), is known to have an eidetic memory, helping him memorize chess games and tactics. Also, during his childhood, he could always surprise his friends by learning pages of sport statistics, simply by reading them once or twice.
- Stephen Wiltshire, MBE, is a prodigious savant[3], capable of drawing the entire skyline of a city after a single glance[4].
- In 1993 taxi driver Tom Morton, who knew over 16,000 telephone numbers in Lancashire, beat the British Olympia Telephone Exchange computer with his recall while being interviewed by Esther Rantzen and Adrian Mills on the popular BBC magazine programme That's Life!. [5]
- Mozart was a possible possesor of eidetic memory, which is especially suited for composers, as demonstrated at the age of 14. At the Sistine Chapel during Holy Week in Rome, Gregorio Allegri's Miserere would be performed. The notes to the Miserere were kept secret under pain of excommunication. On Holy Tuesday, Mozart and his father attended the Papal Mass at the Sistine Chapel. Upon returning to their room, Mozart transcribed the music which had been kept secret for a century.[5] (This is the popular version of that incident. Other sources have him at the Vatican not once but twice (see also Allegri). That would make the event much less a miracle since Mozart was already familiar with difficult composing techniques at that age. He would have recognized and memorized the quite simple harmonic and formal patterns of the Miserere at the first performance and would have used the second one to correct the details.)
- Kim Peek is an autistic savant with eidetic memory and developmental disabilities, resulting from congenital brain abnormalities. He was the inspiration for the character of Raymond Babbit, played by Dustin Hoffman, in the movie Rain Man.
- Nikola Tesla had eidetic memory.[6]
- Mathematician John von Neumann could take a glance at a page of a book and recite it later, without errors, from the beginning to the end.
- Marilu Henner, American actress from the 80's TV comedy series Taxi, supposedly has eidetic memory.[7]
- Professional gin rummy and poker player Stu Ungar was said to have had eidetic memory. He was able to keep track of every card in a six-deck blackjack shoe. In 1977 he was bet $100,000 by Bob Stupak, an owner and designer of casinos, that he could not count down the last three decks in a six deck shoe. Ungar won the bet.
- Saint-Saens was also said to have an eidetic memory. His memory allowed him not only to master music but also the subjects of mathematics, archaeology, astronomy, and the natural sciences.
- Orlando Serrell has had photographic memory since age 10 after he was hit on the head with a baseball.
- Many famous symphony conductors also have eidetic memory where they can "visualize" the conducting score when conducting from memory rather than straight memorization of musical patterns. Among those with this ability are Michael Tilson Thomas, Conductor and Music Director of the San Francisco Symphony and Seiji Ozawa, now retired Conductor and Music Director of the Boston Symphony.
- Jacques Bergier: his friend and co-author Louis Pauwels called him a "living computer"; besides that he was a speed reader and he could read up to 10 books per day.
- Robert Underwood, a boy residing in South Florida, recently was approved by analysts to have eidetic memory. He read a Harry Potter book, and is able to recite it word for word to a crowd.
Controversy
Dr. Marvin Minsky, in his book The Society of Mind, was unable to verify claims of eidetic memory (see sections 15.3 & 15.6) and considered reports of eidetic memory to be an "unfounded myth".
Support for the belief that eidetic memory could be a myth was supplied by the psychologist Adriaan de Groot, who conducted an experiment into the ability of chess Grandmasters to memorize complex positions of chess pieces on a chess board. Initially it was found that these experts could recall surprising amounts of information, far more than non-experts, suggesting eidetic skills. However, when the experts were presented with arrangements of chess pieces that could never occur in a game, their recall was no better than the non-experts, implying that they had developed an ability to organise certain types of information, rather than possessing innate eidetic ability.
Some people attribute exceptional powers of memory to enhanced memory techniques as opposed to any kind of innate difference in the brain. However, support for the belief that eidetic memory is a real phenomenon has been supplied by some studies. Charles Stromeyer studied his future wife Elizabeth who could recall poetry written in a foreign language that she did not understand years after she had first seen the poem. She also could recall random dot patterns with such fidelity as to combine two patterns into a stereoscopic image [8]. She remains the only person to have passed such a test.
A.R. Luria wrote a famous account, Mind of a Mnemonist, of a subject with a remarkable memory, S.V. Shereshevskii; among various extraordinary feats, he could memorize lengthy lists of random words and recall them perfectly decades later. Luria believed the man had effectively unlimited recall; Shereshevskii is believed by some to be a prodigious savant like Peek. However, it is possible that he used memory techniques as well. See his article for further information about his methods.
Memory records
Guinness World Records lists people with extraordinary memories. For example, on July 2 2005, Akira Haraguchi managed to recite pi's first 83,431 decimal places from memory and more recently to 100,000 decimal places in 16 hours (October 4, 2006). The 2004 World Memory Champion Ben Pridmore memorized the order of cards in a randomly shuffled 52-card deck in 31.03 seconds. The authors of the Guinness Book of Records, Norris and Ross McWhirter, had extraordinary memory, in that they could recall any entry in the book on demand, and did so weekly in response to audience questions on the long-running television show Record Breakers. However, such results can be duplicated using mental images and the "method of loci".
Some autistic individuals display extraordinary memory, including those with related conditions such as Asperger's syndrome. Autistic savants are a rarity but they, in particular, show signs of spectacular memory. However, many autistic individuals do not possess eidetic memory.
Synesthesia has also been credited as an enhancement of auditory memory, but only for information that triggers a synesthetic reaction. However, some synesthetes have been found to have a more acute than normal "perfect color" sense with which they are able to match color shades nearly perfectly after extended periods of time, without the accompanying synesthetic reaction.
Many people who generally have a good memory claim to have eidetic memory. However, there are distinct differences in the manner in which information is processed. People who have a generally capable memory often use mnemonic devices to retain information while those with eidetic memory remember very specific details, such as where a person was standing, etc. They may recall an event with great detail while those with a normal memory remember daily routines rather than specific details that may have interrupted a routine.
