- Eidetic memory
Eidetic memory, photographic memory, or total recall is the ability to recall
images, sounds, or objects in memorywith extreme accuracy and in abundant volume. The word "eidetic" (pronEng|аɪˈdɛtɪk) means related to extraordinarily detailed and vivid recall of visual images, and comes from the Greek word είδος (" eidos"), which means "form". [cite web|url=http://www.bartleby.com/61/91/E0059100.html|title=Eidetic|work= American Heritage Dictionary, 4th ed.|year=2000|accessdate=2007-12-12] Eidetic memory can have a very different meaning for memory experts who use the picture elicitation methodto detect it. Eidetic memory as observed in children is typified by the ability of an individual to study an image for approximately 30 seconds, and maintain a nearly perfect photographic memory of that image for a short time once it has been removed--indeed such eidetikers claim to "see" the image on the blank canvas as vividly and in as perfect detail as if it were still there.
Although many adults have demonstrated extraordinary memory abilities, it was previously unknown whether true eidetic memory can persist into adulthood.

Scientific American|accessdate=2007-03-12] [cite web|url=http://psychologytoday.com/articles/pto-20060323-000001.html | title=The Truth About Photographic Memory | accessdate=2006-03] [cite web | url=http://www.slate.com/id/2140685/ | title=No One Has a Photographic Memory | author=Joseph Foer | accessdate=2006-04-27] While many
artistsand composerssuch as Claude Monetand Mozart are commonly thought to have had eidetic memory, 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.

Guinness World Recordslists people with extraordinary memories. For example, on July 2 2005, Akira Haraguchimanaged 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 Pridmorememorized 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 individuals with
autismdisplay 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, most individuals with a diagnosis of autism do not possess eidetic memory. Synesthesiahas 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.
Also, it is not uncommon that some people may experience 'sporadic eidetic memory', where they may describe a rather limited number of memories in very close detail. These sporadic occurrences of eidetic memory are not triggered consciously in most cases.
Marvin Minsky, in his book "The Society of Mind", was unable to verify claims of eidetic memory 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 chessGrandmasters 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. [cite journal | author=Stromeyer, C. F., Psotka, J. | title=The detailed texture of eidetic images | journal=Nature | volume=225 | pages=346–349 | year=1970 | doi=10.1038/225346a0] She remains the only person to have passed such a test. However, the credibility of the findings about Elizabeth are highly questionable seeing as the researcher married his subject, and the tests have never been repeated. Elizabeth refuses to repeat them. [http://www.slate.com/id/2140685] There are more complex figures in "
Foundations of Cyclopean Perception", a book on such patterns by Bela Julesz. [^ Julesz, B. (1971). Foundations of Cyclopean Perception. Chicago: The University of Chicago Press. ISBN 0-226-41527-9. ]
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. He used memorisation techniques where he "arranged" objects along a specific stretch of Gorky Road and went back and "picked" them up one by one. He missed an egg once because he claims he placed it by a white picket fence and did not see it when he went back for it. This is an example of a trained memory rather than a eidetic or photographic memory.
People with eidetic memory
A number of people claim to have eidetic memory, but until 2008, nearly no one had been tested and documented as having a memory that is truly photographic in a literal sense. [cite web | url=http://www.slate.com/id/2140685/ | title=No One Has a Photographic Memory] Regardless, a number of individuals with extraordinary memory that have been labeled by some as eidetikers.
