This is why hyperthymesia is also called “highly superior autobiographical memory (HSAM).” Sure, they can tell you what they were wearing 126 days ago, or perhaps their hotel room number from ten Februarys ago, but neither are going to be able to recite a very long passage in a language foreign to them that they briefly glanced at. The first two have a photographic memory for their own autobiographies (autobiographical memory, which is one half of what is called our explicit memory ) but not for semantic memories.

They nonetheless have one major difference: With photographic memory, the recall part isn’t limited to a brief time after exposure.

In my mind, it’s better described as “flash memory,” as you can perfectly remember something you are exposed to but only for a brief time, like those after images you keep seeing when something is flashed at you and you close your eyes. It’s estimated that about 5% of children and a smaller percentage of adults have this ability, but the one study that this conclusion is drawn from was limited in scope and yet to be repeated. Eidetic memory is defined as the ability to naturally and vividly recall images from memory after only a few instances of exposure, with high precision for a brief time after exposure.
