Frames Per Second

Working Memory Has Limited 'Slots' - Science Daily

For more than a few years now there's been a debate in the enthusiast gaming community over whether the fact that a graphics card can display a certain number of fsp's (frames per second) really matters when it reaches beyond what the eye and brain can physically process. Now, with this new study it appears that the idea that fps only matter up to a point is true. It also makes sense in terms of how we are able to recall events and the fuzziness that can occur in translating working memory into long-term memory. While working memory captures a certain number of images per second it seems the high resolution of those images degrades when shifted into the long term memory. Hence the reason why eye-witness testimony days or months after an event can differ drastically from what actually happened.
But it also explains to some extent the abilities of those who can speed read or have a 'photographic' memory. The ability to take in large amounts of data and then retain the original resolution of that data is a mark of intelligence, it seems. Moreover, since everything our eyes perceive must go through that initial interpretation process it makes more sense that the data is captured by a series of images rather than one continuous stream. There's a momentary gap between what is actually happening in reality and the interpretation our brains make of all that sensory data. Why would evolution make a mind that cannot see reality at a high level of detail unless it allowed some advantage? High resolution fps must then have been an advantage to the early human mind.
