It is actually the use of automatic memory, as this processing is otherwise called, when past experiences are used no matter how long they have not been used. Implicit processing i.e automatic learning is like cycling, swimming or driving a car, once learned it can always be repeated even after a long time.
Explicit processing is also the so-called explicit memory, which involves the conscious processing of information and its memorisation, therefore it uses conscious awareness. This means that learning and gathering information is not automatic as in implicit processing, but is fully conscious.
