Skills in a given discipline, Area or Approach differentiate the novice from the expert. A commonly studied domain is chess playing. It is particularly suitable since it lends itself to representation in terms of problem space theory, in which the initial board / Aircraft configuration and the final position of the King / A/C sequence, constitute the states, while the moves appeared as transition operators. Masters took lesser time than novices to react to a situation and produced better moves. This is largely because chess masters / experienced ATCO’s remember board configurations, A/C positions and good moves associated with them. They can chunk the board configuration in order to hold it in short-term memory. Thus expeditious flow rates are achieved .
It's all quite obvious really.
