Amnesia: ability to learn /train behaviour is maintained even without awareness of pastthe learning process or even the behaviour effectively learned. The evolution of learning is comparable to non-amnesic subjects. This distinction between ability and awareness is also present in other memory impairments like prosopagnosia in which the inability to recognise subjects at a conscious level is contradicted by the involuntary responses at the body level (for example by differences in skin conductance) when in the presence of familiar faces.
