I love to debate, and I might be a little hypo right now, so please don't take this as a personal attack. But since I am feeling really smart...

Norepinephrine (aka noradrenaline) can cause constriction but it is only significant in the skin, digestive tract and kidneys. That explains the pallor but not the initial statement (which wasn't yours) about blood going to the torso instead of the brain. I think that is a myth.
I cannot find any reference to epinephrine (adrenaline) causing constriction.
