Functional properties of motor skill, learning of an anticorrelated skill also diminishes recall memory change with the passage of time. The time-dependent (Brashers-Krug et al. 1996; Rey-Hipolito et al. 1997). With nature of memories in humans has also been demonstrated for the passage of time, sleep disruption and learning of the certain ‘‘declarative’’ memories. When the declarative memory second task have a reduced effect on recall. Therefore the system is damaged, are the time-dependent properties associated influence of certain postpractice events, i.e., retrograde interwith motor memories intact? To approach this question, we examference, is strongest when the temporal distance between the ined five subjects with global amnesia (AMN), including subject event and the instance of learning is short. Third, in some H.M. , and a group of age-matched control subjects. The task was
