You're certainly right there! My early IR work was in real not simulated IMC - grip of death on the controls desperate to stay in control. The other side to to the learning behavior is just that, learned behavior - reverting to what you're learned before. The rudder failure over NY in the Airbus could show how training in fast jets can be a problem for airline operations. After flying GA aircraft to keep your feet of the rudders in a jet and vice versa let alone becoming "ground shy" on landing after operating larger stuff.
