What would we call Gameboy practice?

Several days ago: Four hours on the airplane- a lovely chance to catch up on zencasts. After hearing all I could absorb, I switched to the games on my new iPod. Haven't played electronic games in many many years. Discovered that the gameboy is a fine tool for training attention. Cannot multitask anymore, and operating the wheel took all my concentration. As soon as I started to think- anything at all- could not coordinate the wheel. Wonderful! A biofeedback technique for knowing when I have jumped the trolley back into thought. Not for the longrun, though. No awareness of what derailed me.
