Background
This script implements Millisecond's version of the Cognitive Demand Battery (CDB) by
Kennedy et al (2008). The CDB runs : Serial 3s and Serial 7s subtraction tasks,
a Rapid Visual Information Processing (RVIP) task and a ‘mental fatigue’ Visual Analog Scale.
All tasks can be run with the mouse or touch input.
