Eidetic Memory Test

Mostly no. Eidetic imagery typically lasts from seconds to minutes and is a common stage of normal visual processing. 'Photographic memory' — the ability to recall pages of text or scenes exactly, for years — is extremely rare, poorly documented, and may not exist as popularly imagined.

Haber and others suggested that children rely more on concrete visual strategies before language-based coding matures. As we grow older we increasingly encode information verbally and abstractly, so vivid picture-like memory becomes less common.

There is no reliable evidence that true eidetic imagery can be trained. However, visual memory and attention can improve with practice — techniques like chunking, visualization, and the method of loci help people remember complex patterns much better.
