Implicit memory is evident when the performance of a subject on a task is improved despite the inability of the subject to consciously recollect memories which facilitate to the task. In the case of H.M. (a bilaterally lesioned frontal patient) he was unable to recollect at all his past practicing of a given motor task (such as a video game) even though his performance on the task improved at a normal rate. Such evidence is cited to show a clear distinction between implicit and explicit memory systems in the brain. Importantly, the implicit/explicit memory distinction has nothing to do with the conscious/unconscious distinction. Implicit memory should, perhaps, be understood as non-conscious.
