Emma Stone recently appeared on The Graham Norton Show along with her boyfriend, Andrew Garfield and Jamie Foxx promoting "The Amazing Spider Man 2". What follows is a partial body language analysis.
As she is asked about her reaction to recent reaction to The Spice Girls, Ms. Stone briefly displays a bilateral lower leg rub (0:17). This MAP (Manipulator, Adaptor, Pacifier) is a common anxiety tell. It is more common, but not exclusive in women.
Emma displayed several signals of surprise (and mild shock) - although this one (during 2:14 - 2:15) is the most classic.
Note her eye lids are very widely open (although a moment before they were even more so, e.g.1:59, 2:07 - 2:08) and her mouth takes on a vertically oriented oval and NO TEETH are visible.
After she finds out that Graham was fooling her, Emma displays a classic "Puffer Fish" (2:19 - 2:21). This is very commonly seen before - however more often after a significant event. It is associated with a recent adrenaline surge - then drop off. It helps to down regulate the respiration, blood pressure and heart rate.
Emma's emotional and partial physiologic "collapse" (during 2:24 - 2:26) - although not a complete syncopal episode (fainting) - is common after a dramatic adrenaline surge and speaks to a high sincerity quotient.
