Non-verbal communication, innate or learned?

This article talks about the assumption that non-verbal signs of pride and shame, such as gestures and facial expressions, are learned and not innate.

It seems that even people who have been blind since birth still raise their arms in a great "WOHOO!" of victory and slump their shoulders with disappointment. Frankly, I don't think this entirely precludes the idea that they're learned, but it does open up the question pretty well.
