It allows him to play the game while blind. Ichikawa from Akagi has trained himself to this as regards to Mahjong, and is able to recall perfectly every single draw and play done during any particular round.One inversion is Repeated Rehearsal Failure, where even despite an effort to remember something and rehearsing or repeating it someone still forgets. Occasionally this is a setup for a gag where they've grossly overestimated what they do remember about an event.

If the narrator has this, he is an Infallible Narrator. Sometimes paired with Laser-Guided Amnesia for ironic effect. In this sense, their memory is closer to hyperthymesia than eidetic memory. On TV, every third character has a photographic memory, which here means only that they recall everything they see. A more contemporary example is Jill Price who has almost perfect recall of events that have happened during her life. Solomon Shereshevsky and Kim Peek, the inspiration for Rain Man are some of the closest real life examples of this ability. While many people can claim to possess an extraordinary memory, most researchers believe that it is unlikely that true eidetic memory exists in adults, and most cases of "real life" photographic memories are either the result of intense training and devotion, such as among composers, or abnormalities of the brain. Someone with an eidetic memory can look at something, remember it later, and, when remembering it, notice details they completely missed the first time. Someone with a good memory can notice details about something they see, and then recall those details months later. True eidetic memory is not simply " exceptional memory for details", but involves memory which actually works in a way vastly different from normal memory, specifically, the ability to "capture" an image after a short exposure, such that the eideticer has the subjective experience of actually still seeing it even after it has been removed. Photographic Memory, technically called eidetic memory, is the ability to recall images, sounds or objects in memory with near perfect accuracy and in abundant volume.
