Mnemonic Curve - Version 1 Mnemonic Curve is fundamentally a game. The object of the game is to remember and repeat a sequence of mouse-clicks within a group of circles. Mnemonic Curve demonstrates two principles governing our ability to remember a sequence of choices. 1) Length: A longer sequence of choices is more difficult to remember than a shorter sequence of choices. 2) Complexity: A sequence of N choices in which each choice involves many possibilities is more difficult to remember than a sequence of N choices in which each choice involves only a few possibilities. Together these two factors create what I'm calling the Mnemonic Curve. The Mnemonic Curve looks like the right half of the ubiquitous bell curve.
