In this episode Amy is letting her moment-to-moment
cerebral activity become a part of the monologue. Often this naturally
occurring mental action gets shut down as an actor grinds his or her way
through the words. They literally look as if they are thinking very slowly or
not at all. The net effect is that the actor seems somewhat less than human.
By the way, allowing the cerebral activity to be a significant
part of what you are experiencing is extremely important when you’re are
working on camera. If you’re negating the cerebral, there will be an unnatural
emptiness to your performance.
