Acquisition of expertise on a difficult perceptual-motor task by an amnesic patient

While numerous studies have reported learning of perceptual-motor skills by amnesic patients, few if any have documented the eventual acquisition of expertise on a given task. This paper recounts the learning of the computer game Tetris by a hippocampal amnesic, whose acquisition of the task in a formal evaluation was somewhat slower than that of a comparison group, but who after many hours of self-paced practice achieved expert-level play.
