Book Definition: An especially clear and persistent form of memory that is quite rare; sometimes known as "photographic memory."

History


This is very rare, but people with eidetic memory can recall images, sounds, and objects in their memory. The word 'Eidetic' means something related to extraordinary detailed recollection of visuals and images(Greek).Some people see this ability as an advantage,such as being able to remember equations on tests because they can create mental images. But others see it as a curse, because people with eidetic memory struggle to forget bad memories. Ex- It's hard to forget the moments of when you were with your ex-boyfriend. Whether or not this ability is genetic is still unknown.

  3. Harvard Test
  • An experiment was done by Leonard Doob in 1964 to see if eidetic imagery is higher among people that are illiterate verses people that are literate. So he went to the Ibo, people in Eastern Nigeria, to test his theory on the rural and urban people. The experimental group varied in age and gender so there was no bias. They were presented a picture that they have never seen before and were asked to describe what they just saw. The results showed that the illiterate group was able to convey what they saw more so than the literate group. Afterwards, Doob concluded that eidetic imagery in the Ibo's decreased with age and schooling.
