A good example of pressure vs decision making is a subtle engine failure on final in a turboprop.
If done correctly while the levers are back on idle, the speed loss which occurs before recognition and corrective action can be significant.
I've seen this stuffed up many times where crew instinctively begin to run out of airspeed, and eventually start decide to push up the operating engine and go around. As the loss of control approaches, the only thing to be done is reduce the operating engine power.
Every transport pilot understands that reducing power on the operating engine will increase controllability/decrease Vmca, but so few have the brain space to implement this - only sim instructors or examiners on type who've seen it over and over and who are regularly exposed.
This is why V1 concepts have to be kept simple - knowing and understanding something is completely different to being able to reliably apply deep knowledge in high pressure/low time available situations.
