The system will display the word "Stop" or the word "Go" on the screen rapidly. When the word "Go" appears on the screen, the user is to tap the space bar. From time to time the user will tap the space bar by accident when the word "stop" is displayed. The system will score success rate of pressing space in the right place. This does need to be a random system and not one which the user can predict a pattern with.
