Andrew Garfield was recently on "The Tonight Show with Jimmy Fallon" plugging his recent film, "The Amazing Spider Man 2". Jimmy surprised Andrew with a guitar and then asked him to play a song. Emma Stone's boyfriend responded with a pretty fair rendition of the Spider Man Theme.
There are several nonverbal anxiety tells in this short video displayed by the 30 year-old actor. Very early (during 0:05 - 0:07, Note: Unfortunately, since the original writing of this post, the source video has since been deleted from YouTube) - Garfield picked a piece of lint off his shirt and discarded it (preening) while Fallon looks on. In this scenario, this MAP/MAP surrogate nonverbal (Manipulator, Adaptor, Pacifier) is highly indicative of anxiety (In other situations clustered with nonverbals - it can have a completely different meaning).
