“The basic unit of analysis in face-to-face communication is the
feedback loop. For example, if you were given the task of describing an
interaction between a cat and a dog, you might make entries like: "Cat
spits, ... dog bares teeth, ... cat arches back,... dog barks,... cat�"
At least as important as the particular actions described is the sequence
in which they occur. And to some extent, any particular behavior by
the cat becomes understandable only in the context of the dog's
behavior. If for some reason your observations were restricted to just
the cat, you would be challenged by the task of reconstructing what the
cat was interacting with. The cat's behavior is much more difficult to
appreciate and understand in isolation.”
