Most scientists believe there are at least four general types of memory:
- working memory.
- sensory memory.
- short-term memory.
- long-term memory.
There's no scientific evidence that you can train your memory to become photographic. You can, however, train your brain to remember more.
Sheldon possesses an eidetic memory and an IQ of 187, although he claims his IQ cannot be accurately measured by normal tests.
Fewer than 100 people have a photographic memory. Photographic memory is the ability to recall a past scene in detail with great accuracy – just like a photo. Although many people claim they have it, we still don't have proof that photographic memory actually exists.
Photographic memory is a term often used to describe a person who seems able to recall visual information in great detail. Just as a photograph freezes a moment in time, the implication for people thought to have photographic memory is that they can take mental snapshots and then recall these snapshots without error.
This rare condition also known as highly superior autobiographical memory (HSAM) causes people to remember just about everything that has occurred in their life. The cause of Hyperthymesia is still unknown but some researchers believe that it is genetic while others think it may be molecular.
In five minutes, 32-year-old Boris Konrad can memorize more than 100 random dates and events. After 30 seconds, he can tell you the order of an entire deck of cards. During the 2009 German Memory Championships, Konrad memorized 195 names and faces in 15 minutes—a feat that won him a gold medal.
CONS Forgive and forget is obviously out of the question, meaning that the disorder can easily interfere with relationships and mending conflict. Additionally, research shows that the overloaded stream of memories can disrupt an average day's activities (i.e. work, exercise, a mediocre task).
It is generally accepted that no-one can recall their birth. Most people generally do not remember anything before the age of three, although some theorists (e.g. Usher and Neisser, 1993) argue that adults can remember important events - such as the birth of a sibling - when they occurred as early as the age of two.
Most adults suffer from childhood amnesia, unable to remember infancy or toddlerhood. That's what scientists thought. But a new study indicates that even six years after the fact, a small percentage of tots as young as 2 can recall a unique event.
Hyperthymesia is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail. It is extraordinarily rare, with only about 60 people in the world having been diagnosed with the condition as of 2021.

Lifestyle Changes That Can Improve Your Memory
- Sleep on It. Here's an easy way to boost your memory: Get a good night's sleep or take a power nap after learning something new.
- Get Moving.
- Improve Your Diet.
- Make New Connections That Are Visual (and Perhaps Outrageous)
- Write It Down, Don't Type It Out.
Adults can generally recall events from 3–4 years old, and have primarily experiential memories beginning around 4.7 years old.
Direct sensory memories only last a few moments. Some go on to make short-term memories, such as the phone number you just dialled. Exact figures are hard to pin down, but an average brain can probably keep around four things in mind at once, for up to 30 seconds.
Our brains aren't made to remember everything that we encounter. Unless you're one of the rare individuals who has a photographic memory, it's likely that details about the content you consume fade quickly.
Confabulation is a symptom of various memory disorders in which made-up stories fill in any gaps in memory. Someone with confabulation has memory loss that affects their higher reasoning.
People with good memory, on the other hand, are referred to as eidetic. Eidetic memory or photographic memory would be the correct term.
In the scientific literature, the term eidetic imagery comes closest to what is popularly called photographic memory. Eidetic images differ from other forms of visual imagery in several important ways.
Semantic memory refers to the memory of meaning, understanding, general knowledge about the world, and other concept-based knowledge unrelated to specific experiences.
Forgetfulness can arise from stress, depression, lack of sleep or thyroid problems. Other causes include side effects from certain medicines, an unhealthy diet or not having enough fluids in your body (dehydration). Taking care of these underlying causes may help resolve your memory problems.
Robert Evans can identify new objects that appear in starfields of 1500 galaxies. Akira Haraguchi holds the Guinness World Record for the most decimal places of pi recited by memory. His ability is self-attributed to a strong eidetic memory, though he uses a mnemonic device.
Eidetic memory is the ability to see an object soon after you look away. For most people, the image lasts mere seconds or less than one second. To get an idea of how well your brain makes use of eidetic memory, look at an object and close your eyes, and see how long you can still see the object in your mind's eye.
10 Ways to Develop a Photographic Memory
- Train for an eidetic memory test.
- Store up on omega-3s.
- Slow down—and repeat, repeat, repeat.
- Pound the pavement.
- Don't skip your morning coffee.
- Keep your calendar packed.
- Get your choline fix.
- Get tipsy. (Yes, really.)
