Implicit memory: Recent studies have indicated that many of the memories remain outside the conscious awareness of a person. Implicit memory is a kind of memory that a person is not aware of. It is a memory that is retrieved automatically. One interesting example of implicit memory comes from the experience of typing. If someone knows typing that means s/he also knows the particular letters on the keyboard. But many typists cannot correctly label blank keys in a drawing of a keyboard.

Implicit memories lie outside the boundaries of awareness. In other words we are not conscious of the fact that a memory or record of a given experience exists. Nevertheless, implicit memories do influence our behaviour, This kind of memory was found in patients suffering from brain injuries. They were presented a list of common words. A few minutes later the patient was asked to recall words from the list. No memory was shown for the words, However, if s/he was prompted to say a word that begins with these letters and two letters are given the patient was able to recall words. Implicit memories are also observed in people with normal memories.
