I absolutely agree with cleaning while cooking. Sauce has sputtered on the rage top, go ahead and wipe it off while it's still liquid. If I'm done cutting on the cutting board, rinse the board and kind off while things are cooking.

That said, I suspect that ability to clean and cook at the same time comes with experience and comfort with the cooking task. If imagine the same goes for socializing while cooking. Some meals I can do on autopilot and have the connotative capacity for other tasks, while others I ask the family to give give me some room to focus.
