The Magical Number 7

George Miller, born in the USA, famously created the magical number 7, which had been following around him for years. He produced an article that became the well known for cognitive psychology and working memory which later introduced the idea of artificial intelligence closer to reality. George Miller main interest was in psycho-linguistics, that derived from the World War II on speech perception. As speech perception involved the field of communications, which introduced him in to information theory. Much of George Miller understand was inspired by Claude Shannon, who was investigating ways of turning messages into electronic signals. Claude Shannon's model of communication consisted of bits and Claude Miller used this reversibly to apply interpreting his mental processes into the idea of channel capacity (the amount of information of which the system could process). 

 In an experiment conducted by Irwin Pollack, a physicist and acoustic specialist, played around seven different tones of which was able to be remembered, however, any more than seven, did the results then start to deteriorate. Another experiment by Lord Kaufman in 1949 tested by in front of participants by flashing numbers of colored dots on to a screen in front of them. These experiments helped George Miller to see the mind as a human communication system. Input of information fed into the mind results in the transmission of details to the mind to increase initially before leveling off an individuals capacity.
