I think the only general claim that could be made is that the brain prefers to be certain of what's going to happen/what did happen. To get that you either need to have a good feel for where a motion is going to end up (which is harder the more inexperienced you are, and the more complex/farther the motion), or to get feedback.

Personally, I also struggle with a relatively high rate of accidental (or mis-registered) key presses, or being in the wrong mode, which means that even if I have high confidence in constructing the right command in my head, my confidence in the right command being executed is significantly lower, and direct, always-on feedback thus feels enormously helpful to me.
