11 * Interface for tasks, where each describes a fundamental relation between exogenous inputs causing a mental task demand. The
12 * concept of anticipation reliance can be included, which is a reduction of mental task demand by prioritizing a primary task
13 * and relying more on anticipation regarding secondary tasks. Control over the amount of anticipation reliance is
14 * implementation dependent, but is typically not part of the task itself.
