"Democrats belive in a free market..."

Despite her post as House Speaker, Pelosi is awfully bad at hiding her emptions. Take a look at the movement of her face and shoulders right after she says "democrats believe in a free market" in a floor speech right before voting for the proverbial "bailout bill".



The instant she says this, her head tilts back and turns counterclockwise. Her shoulders shift up and down in a 'retreating gesture'. Take a look at the below video at around 1:52 (or use this link).



It seems as though Pelosi is retreating from her very words as though she does not quite believe what she just said. The series Lie To Me (it's the second episode) demonstrated this so called "gestural retreat" showing Nixon's famous "I'm not a crook" speech after which he crosses his arms and steps backward (click this link). Unfortunately however I have not found anything regarding "gestural retreat" in the academic literature. If someone knows of a paper, I ask you please post a comment.
