He published the two-dot test in newspapers and magazines, hoping he’d find someone who could do the same thing Elizabeth had. John Merritt, another researcher, tried to duplicate the study with others. However, the validity of these test results was called into question when the scientist who studied her, Charles Stromeyer III, married her and she was never tested again. A Harvard student named Elizabeth could allegedly look at a pattern of random dots with her right eye, then a different pattern with her left eye, and then mentally layer the dots on top of each other, which formed an image where the dots overlapped (similar to a “Magic Eye” stereogram). Only one case of a photographic memory was ever recorded in scientific literature, and the research has some holes in it. It probably doesn’t work-there’s no scientific evidence to back up the existence of a photographic memory. How does that work, considering everything we’ve learned about the memory so far? So what’s the difference between photographic and eidetic memory? Most people have probably heard of a “photographic memory,” which is the ability to take a mental snapshot of something detailed, such as a page of a book, and recall it in perfect detail.
