What you do
Count amber on the lamp, click X headcodes, then do both at once.
Why it is useful
One stream is easy. Two is the test. Cab work is rarely a single display. The second job should not collapse the first.
Dual task · ~2 / 3 / 5 min
What you do
Count beats, match symbols, then do both at once.
Why it is useful
Cab work is two streams. Dual-task tests whether the second job collapses the first. The wrapper feels unfair the first time you meet it. After a few runs, your hands stop arguing with your ears. That familiarity is a lot of the difficulty, and it is trainable.
Dual task · ~2 / 4 / 6 min
What you do
The rule flips between vowel, even, and blue. Answer Yes or No each time.
Why it is useful
Staying on one rule is cheap. Switching costs. Operators need people who can drop the last instruction and take the new one without a lag that eats the trial.
