(There’s more on this technique, called chunking, in part 2.) Using this method, by the end of the testing, SF could remember over 70 digits. For example, 4, 1, 1, 9 became 4 minutes and 11.9 seconds, the time it might take him to run a mile. SF was a runner, so he started thinking of the random digits as running times. Then, however, he came up with a new method. He remembered them by chanting them over and over to himself, which is called a phonological loop. Initially, SF, like most people, could only remember about seven digits. In the test, someone reads out a new number every second and the test subject must remember the sequence. SF took digit span tests, which measure a person’s ability to hold numbers in their working memory, for 250 hours over two years. Anders Ericsson and Bill Chase found that people can train and improve their memories.Įricsson and Chase tested the memory of SF.

If our brains are naturally good at remembering certain things and naturally bad at remembering others, is there anything we can do to improve our memories? Is memory like vision or height-you’re stuck with what you’ve got-or more like a skill you can improve? For a long time, scientists thought our memory abilities were fixed, but in a study that took place from 1981-1983, K. Now that you know the difference between photographic and eidetic memory, the next question is whether or not these types of memories can tell us anything about improving memory. People who have eidetic memories can remember images longer than the average person, but not in more detail than the average person. This is the main difference between photographic and eidetic memory: we can prove eidetic memories exist, but not photographic memory.Įidetic memories, however, are real. People responded, but once in a lab, none of them could do it. He published the two-dot test in newspapers and magazines, hoping he’d find someone who could do the same thing Elizabeth had. John Merritt, another researcher, tried to duplicate the study with others. However, the validity of these test results was called into question when the scientist who studied her, Charles Stromeyer III, married her and she was never tested again. A Harvard student named Elizabeth could allegedly look at a pattern of random dots with her right eye, then a different pattern with her left eye, and then mentally layer the dots on top of each other, which formed an image where the dots overlapped (similar to a “Magic Eye” stereogram). Only one case of a photographic memory was ever recorded in scientific literature, and the research has some holes in it. It probably doesn’t work-there’s no scientific evidence to back up the existence of a photographic memory. How does that work, considering everything we’ve learned about the memory so far? So what’s the difference between photographic and eidetic memory? Most people have probably heard of a “photographic memory,” which is the ability to take a mental snapshot of something detailed, such as a page of a book, and recall it in perfect detail. What’s the Difference Between Photographic and Eidetic Memory? Read more about the difference between photographic and eidetic memory below. There is no definitive evidence of photographic memory. The difference between photographic and eidetic memory is simple: eidetic memories exist. What is the difference between photographic and eidetic memory? Do photographic memories really exist?
