Hi JD-EE,
Communications is the solution.
I agree when conducted in a calm, relaxed atmosphere. Verbal communications on top of the plethora of cockpit noises, causes some noises to be filtered out. (Stall Stall??).
The big advantage of connected control wheels, is Pilot A Knows what Pilot B is attempting to do without a word being spoken.
AB have designed a flight deck where the crew are separated by their control sticks. They may as well be in separate rooms talking to each other on the telephone whilst watching their individual Flight Displays.
