After the World War 2, much of the psychology discipline followed on from Behaviorist and started to move towards practical applications rather than theoretical. Donald Broadbent, from England, studied psychology who met Frederick Bartlett. Bartlett believed one of the most important theoretical discoveries are often made while attempting to find solutions to practical problems. This idea, Broadbent found appealing which prompted him to combine and evolve into his work.
During Broadbent time with the RAF, he concentrated on problems and and applied to pilot display of informational data. He was interested in how pilots could organize their information and what design changes would support this. A pilot had large volume of information to take in at any specific point in time and then select the appropriate handle levers, controls or flaps situated around a dashboard. The volume of information and also the controls, at a small point time duration on the basis of decision making control.
At the same time, code breakers, Alan Turning were also tackling the notion of information processing and created the idea of "Thinking Machine". Donald Broadbent turned this idea around in comparison to human thinking machine as a information processing. This created the distinguish between cognitive psychology from behaviorism (a study of the mental processes rather than the manifestation behavior).
