What is a photographic memory?

[interested_learner]

One of the finest engineers that ever worked for me had a photographic memory. She worked with MIBs which are fiendishly complicated databases used by the telecommunication world. She could remember everything, no matter how complicated. That talent was very useful as you can imagine. She also had played oboe in a major orchestra, never having to read the music since she had the classical repertoire memorized. She had quit because she said it was boring and didn't pay well enough.

She said that the biggest drawback to having a photographic memory is that she remembered every bad thing a person had ever said or did to her. This made relationships difficult.

Wasn't Raymond autistic? Being weird and strictly regimented is very typical for autistic people, and his brother even tries to unload him on a mental hospital, saying Raymond is autistic.

Perhaps I should have used the word autistic instead of introvert. He is more importantly a savant. How is it he can remember all the names in a phone book after one reading? By autism? No by being a savant that has a photographic memory I think. Check the movie and you will see he is characterized as a savant. Since autistics are totally into themselves I think it was safe for me to call him an introvert even thought he was diagnosed an autistic.

I've had students that are autistic and until I was told they were clinical autisticis I deemed them introverted, because I am not a psychiatrist. None of them were anywhere close to being a savant. They had no distinguishable abilities and were difficult to instruct. They would soon forget what I thought they learned and had to be inculcated in even the most basic things.

His brother not only didn't want to unload him, but tried very hard to keep him with him even though it cost him a large sum of money offered him to leave Ray at the institution.

I haven't seen this movie for a while and I don't have a photographic memory, but I can safely say you sure don't, unless you never seen the movie and are going on heresay.

i also remember everything said in a faculty meeting or preceding a vote. then when things are reconsidered the following year, and some people change their stories, i remember what was said before, but everyone else claims to have forgotten. since the past discussion is as clear as day in my memory, i really have wondered whether they were being candid, but maybe some people really do forget things.

i also used to record movies to view again. but discovered that it takes me at least 2 years to forget the movie enough to want to see it again. by then it has been on tv another two dozen times or more.

what is the Opposite of photographic memory

Does anyone know what the Opposite of a photographic memory is? I call it the void and it causes me extreme heartache. I have never been able to being someones face to mind. I have a wonderful wife and daughter that I love greatly. However, I can not see their faces when I am away from them. When I dream, I do not see things in my dreams, I simply feel as though I am doing something in the dark. Has anyone heard of this and what can I do to correct it.

Thanks

The Void

I'm sorry to hear that.
Perhaps this might help, as it sounds like a related problem: http://en.wikipedia.org/wiki/Prosopagnosia

Thank you for the information. However, this as to do with any image you can think of. Example, If I told you to bring to mind a big oak tree with a rope swing attached, you could probably close your eyes and see the tree and tell me everything about that tree. When I think of the tree, I can tell you the parts of the tree put I can not see the tree. With faces, I can not see them when they are not present. However, when I meet the person I know exactly who they are. Recently I went to one of my class reunions. Because I had not even thought of 90% of these people and had moved away right ofter graduation, I had no idea who they were. However the close friends I had, once I saw them, I knew exactly who they were.

I'll remember everyone and maybe even the details too.

Posting #21 in this thread suggests: 'Derren Brown(psychological "magician") has also trained his memory in this way, he was given about an hour to memorise a book at random from the Britsh library [...]'

I don't know whether 'Photographic (or eidetic) memory' exists, but Derren Brown certainly hasn't got either as claimed in a UK TV program from 2001 referred to in the a.m. posting. (The video can be found on YouTube - 'Derren Brown Photographic' will get you there). He does use versions of the so-called 'book test' and I know how he created the illusion of having learned the OED by heart in 20 minutes. It's not what really happened.

I cooperated in this video 'for fun', following a bet that I could get myself on telly. I think I can actually claim that I tricked Derren Brown. I am dining out on that ever since, especially at Christmas time. Tangentially I also enjoy being called a ‘miserable nerd’ by YouTube uebernerds for claiming to be 'that librarian'.

Would you care to share?

Dave: I like stage magic and would normally not disclose the tricks involved to create the illusions. Derren takes liberties with the artistic licence. Here, in brief, his lazy tricks: Derren uses versions of the 'book test' which (for learning the OED 'by heart' in 20 minutes) in this instance involves inviting the 'subject' (here: the librarian) before the show / video shoot to write down page and line of a chosen word from a genuine copy of the OED on a prepared clipboard ('so that you don't change your mind') which then gives Derren the page and number for the chosen word, and at the same time allows for cameras and screens to be primed for the 'reading' from the second (truly) random book. Only two of some eight librarians attending were invited to do the actual video, only one is shown. The whole procedure took over two hours and some six assistants and technicians and were involved setting up lights and cameras.

As always, the explanation of a magic illusion tends to be much more mundane than a layperson may want to imagine. No NLP, subliminal suggestion or hypnosis was involved, and certainly no photographic memory (or photo-reading) is demonstrated.

Yes, but you did crack the door open...so I stuck a foot in

Yes, I've been observing Chris Angel myself. His tricks look spectacular on the surface. I was skeptical so I read up on him a bit. As I suspected, the most important thing to know about him is that he is a TV celebrity. Many of his more spectacular tricks are a result of clever editing of his footage to give an illusion of a trick more spectacular than it is. He counts on his TV audience assuming that what they're watching is an unedited sequence of events in a bona fide setting. It would be interesting to go see his stage show and observe how many of his tricks he can not do live.

I feel I have something of a photographic memory, I believe its what helped me do well in geography bees and such with the ability to "see" things on a map and such.

 

[mbisCool]

I got to the 24th part of the lighting sequence in that game simon on my second try...

Also one thing I have always hated is hearing people quote songs or movies and they say the wrong words

How do you know your memory is different from other people's memory or has a higher 'photographic' content than e.g. mine?

 

[Raizy]

Making analogies with computer science is mildly pseudoscientific but fun! :)

Here it goes.. starting with an example to set up the scene.
When you see the "Coca-Cola" logo, you identify it as being the "Coca-Cola" logo, and when you will recall that white text on red background, you will know what it is.
But... can you draw it?
Take a pencil and draw it! Most people will fail miserably.
Why?
Because the "normal" memory is lazy and just uses the meanings of items (in the same ways Java / C# use pointers to objects).

Photographic memory is the exact opposite. Photographic memory isn't concerned with the "meaning" of a memory, instead it just cares about the "image data" of the memory itself.
Spotting the license number of a speeding car involves the photographic memory: like an imprint in some area of the brain you can spell out the letters (meaning) afterwards and yes, you can train to do this, too. :)

Ahh I remember watching something on discovery about some dude who could draw an entire city block in tremendous detail and accuracy. They need to give him a job in the video gaming industry for level design.

Where exactly do I say that I feel mine is "more" than anyone elses? (Should say, "Nowhere, I don't think" about now. Precisely.

I just know that in my memory depending on the subject I visualize much more than with other subjects.

 

[WarPhalange]

My brain is slow so I have to rely on a photographic memory.

For example when I look at a phone number, I don't immediately process and remember what those numbers are. I take a mental snapshot and then recall that picture in my brain and then I process what those numbers are by looking at them in my mind one by one. Then I immediately forget them, but might still remember the snapshot for a while.

But, for all I know, everybody else does that. How am I to know how other people think?

EDIT: I kind of do the same thing when being spoken to, like being told instructions, addresses, or phone numbers. I don't immediately process the information as its being told to me, I just remember the sounds of the words and later parse it all to understand what was said. This is only when I have to memorize something, not when I'm learning, though.

This sounds like the result of ambiguity in the term photographic memory. The common (though not necessarily correct) understanding of the term photographic memory is usually something more akin to total recall, whether or not the memory is visual. (Wiki even notes the confusion in these and related terms. Try googling 'wiki photographic memory').


It sounds to me like
binzing meant "visually (i.e. photographically), I have excellent recall, when compared to other types of my memory"
whereas
RWentz heard "I have a photographic memory (i.e. total recall), which is superior to the average person's memory recall".

 

[binzing]

That sounds about right Dave, thanks for clarifying. I was a little rude in that post, I'd been on edge.
