Tower of Hanoi

The Tower of Hanoi is a puzzle that consists of three pegs and a number of different sized rings, usually five.  When stacked on a peg, the rings form a pyramid.  The objective of the task is to move the rings from the first peg to the third peg while keeping the smaller rings on top of the larger rings.  Only one ring can be moved at a time.
A study by Cohen, Eichenbaum, Decedo and Corkin (as cited in Allard, 2001) tested amnesics and normal subjects on their ability to learn how to solve the puzzle.  Amnesics learned the task at the same rate as the normal subjects.  This showed their ability to learn a procedural memory task despite no recollection of previously performing the task.

Tracking Tasks

A famous amnesic, HM, was found to be able to learn and retain a variety of simple motor tasks which rely on the procedural memory system.  Some examples of these procedural tasks are mirror tracing and rotary pursuit.  With practice, HM's performance improved although he had no memory of ever performing the task before.  He required instructions each time he performed the task.  (Corkin, 1968).

Golf

An individual with only functioning procedural and sematic long term memory, MT, played golf with a researcher named Schacter.  Schacter's observations showed that MT could not remember ball position due to his lack of episodic LTM.  He maintained his golf performance and etiquette, demonstrating his intact procedural & semantic LTM systems respectively.
