Attention switching
Can you switch rules fast?
Attention switching tests how quickly you can update the active rule without carrying the old one into the next task.

Quick answer
The short version
Switching rules creates a small cost because your brain has to inhibit the old rule and load the new one.
How to test it
1
Use two simple rules.
2
Switch rules at unpredictable points.
3
Track errors separately from speed.
4
Notice whether old rules intrude.
