"Countless psychological experiments have shown that, on average, the longest sequence a normal person can recall on the fly contains about seven items. This limit, which psychologists dubbed the "magical number seven" when they discovered it in the 1950s, is the typical capacity of what's called the brain's working memory.read complete article : In the Brain, Seven Is A Magic NumberNow physicists have come up with a model of brain activity that seems to explain the reason behind the magical memory number.
If long-term memory is like a vast library of printed tomes, working memory is a chalkboard on which we rapidly scrawl and erase information. The chalkboard, which provides continuity from one thought to the next, is also a place for quick-and-dirty calculations.
