They responded by telling him exactly which words the pin passed through on every page. According to a paper published in 1917 in the journal Psychological Review, psychologist George Stratton tested the Shass Pollaks by sticking a pin through various tractates of the Talmud. A group of Talmudic scholars known as the Shass Pollaks supposedly stored mental snapshots of all 5,422 pages of the Babylonian Talmud. In every case except Elizabeth’s where someone has claimed to possess a photographic memory, there has always been another explanation. Children with eidetic memory never have anything close to perfect recall, and they typically aren’t able to visualize anything as detailed as a body of text. An eidetic image is essentially a vivid afterimage that lingers in the mind’s eye for up to a few minutes before fading away.
For example, a Japanese engineer - Akira Haraguchi - has memorized the mathematical constant pi to its first 100,000 decimal places.Photographic memory is often confused with another bizarre-but real-perceptual phenomenon called eidetic memory, which occurs in between 2 and 15 percent of children and very rarely in adults. Many people have developed extraordinary memories over time by using a variety of skills and learning techniques. In fact, most claims of true eidetic or photographic memory are merely word-of-mouth reports that haven't been proven scientifically. Some scientists have observed that individuals with autism or autism spectrum disorders, such as Asperger syndrome, may occasionally exhibit exceptional memory that resembles eidetic or photographic memory.įor the most part, though, extraordinary memory events are just that - extraordinary, but not necessarily up to the level of eidetic or photographic memory. People who can do this - sometimes called eidetickers - claim that they can “see" the image in their minds as if it was still right before their eyes. One example of eidetic memory is the ability to study an image for about 30 seconds and keep an almost-perfect photographic memory of that image in the mind after it's removed. Eidetic memory, on the other hand, refers to precise recall that can involve details gained from the other senses, such as hearing, feeling, taste, and smell. Photographic memory often refers to precise recall of mainly visual images. The word “eidetic" comes from the Greek word that means “seen." Eidetic memory is actually broader than photographic memory. Photographic memory is the common name for eidetic memory. This means they can recall things they've seen or read with almost-perfect precision, even down to the smallest of details. Some people even claim to have a photographic memory. Have you ever gotten down to the last couple of questions on a test, but you just can't seem to remember the answer? At these times, you probably wish you could see the pages of your textbook like a photograph in your memory.ĭo you know someone who has a really good memory? Some people are gifted in special ways when it comes to exceptional memory. Sometimes you might wish you had a better memory. Do you like tests? If you're like most kids, the answer is probably a resounding “No!" Tests can be a lot of work, especially in subjects like history that have a ton of facts to remember.
