Anticipation is also a device to catch the audience's eye, to prepare them for
the next movement and lead them to expect it before it actually occurs.
Anticipation is often used to explain what the following action is going to
be. Before a character reaches to grab an object, he first raises his arms as
he stares at the article, broadcasting the fact that he is going to do
something with that particular object. The anticipatory moves may not
show why he is doing something, but there is no question about what he
is going to do next. [26]
