chimp audience monitoring

Here is a brief story while I work on a longer post. The NYT tells of a study of chimp communication that contradicts much of what I read and indicates that they, too, have a Empathy Central (or Theory of Mind to you orthodox).  Check it out:  https://www.nytimes.com/2017/11/15/science/chimpanzees-communication-language.html.  The researchers (humans, that is) put a plastic snake on a path the chimps used regularly and waited for one to come along.  As the chimp approached the humans played a recording of either a chimp giving a resting call or a danger call.  When the walking chimp saw the snake, he or she, of course, gave a danger call.  If they had just heard the resting call, they gave more danger calls and looked around for others to make sure they knew about the snake.  If they had just heard the danger call they reiterated that but did not enlarge upon it.  This demonstrates pretty well, I think, that chimps monitor their audience and adjust their communication accordingly.  This is a high level skill, perhaps in an incipient phase, but still demonstrates awareness of what is going on in another’s mind and then to communicate accordingly.  Still to be examined is if some male chimps ‘mansplain’ and go on and on boring the others with irrelevant incoherence.

I knew all this already. Why does he go on and on?
