I also believe that a beginner skier feels exactly the same thing--the same adversity. Certainly the reality is not the same. But reality and rationality don't always (and even "often") drive the action. Emotion is at least as powerful. Such considerations as trust, confidence, and anxiety-management tend to be either subtle or strong. Nevertheless to deny their presence--or to say that just technique, or just will, or just good tactics and finesse will solve everything or explain everything--is, in my view, a narrow analysis.
Each person brings a unique history and set of skills and tools to the game, and each will react accordingly. I find it to be really interesting to look at the unmeasurable elements as well as those that are more concrete. As a teacher, I have to be cognizant that my picture of a walk on the park may be someone else's version of an incredibly courageous attack.
