I don't know if it has been changed for the MAX (probably not), so the following is for the NG:
The stick shaker has multiple inputs. Primarily AoA, but also other ADIRU inputs, thrust, flap/slat configuration, etc.
Although there are two shaker systems, either will shake both control columns because they are mechanically linked by a rather rigid (though frangible) connection.
Stick shaker activation will be recorded on the FDR and can probably be heard on the CVR as well.
