Eidetic Memory
Definition
Eidetic memory refers to the ability to retain images or scenes with photographic accuracy after brief viewing. It is the opposite of aphantasia.
Detailed Explanation
Eidetic memory, often incorrectly called "photographic memory," enables storing images for a short time with high detail accuracy and recalling them. It is more common in children (2-10%) and decreases with age. True eidetic memory in adulthood is extremely rare. People with eidetic memory describe being able to "see" images before them and read details by examining this inner image. This stands in stark contrast to aphantasia. The neurological foundations are not yet fully understood, but increased activity in visual storage areas is suspected. Eidetic memory should be distinguished from hyperphantasia: the former refers to memory performance, the latter to imagination ability.

Hyperphantasia refers to the ability to form extremely vivid, photorealistic mental images. People with hyperphantasia can imagine scenes so detailed that their inner images can almost be confused with real perception.
