It is a type of memory based on visual images that the brain retains for at least 30 seconds with sufficient clarity so that they can be projected and visualized in detail before the subject. Interestingly, they look best if the eyes are pointed at a flat surface, like a blank piece of paper.
Thus, for example, an eidetic image of the page of a book would allow, once closed, to contemplate it as if the page of the book was still open before us, in such a way that we could use that mental image to "read" the content and extract information .
Eidetic memory, also popularly called photographic memory , rarely manifests itself in adults, but it is estimated that eight out of 100 children have it.
