Infant Pointing

Wren points all the time so I was interested to receive reports of a new study on babies' pointing:

A new theory of infant pointing provides evidence that when 12-month-old infants point for an adult, they are trying to influence his or her mental state, rather than using the adult as a "tool" to obtain a desired object. The evidence suggests that infant pointing is produced by the uniquely human motivation of cooperation, and that it is an essential milestone in the development of language skills.

"Ah ha!" or "What?"

I guess this theory suggests that when Wren points at a ball or fan or cat he is not wanting me to say "CAT" or to GET THE CAT or "LOOK, A CAT" he is trying to co-operate with me in things CAT.

Still, its ambiguous. Influence the adults mental state how exactly? Drive the adult nuts? Get the adult confused? Get the adult co-operating in pointing?

This adult's mental state is influenced, okay!

MEANWHILE:
This is Frost's poem of the morning:

If you heard a bang in a park
Then there would be two things waiting for you
Because if you take the b off the bang
Then that spells Ang, the avatar
And if you put the reakfast in front of the missing B
That spells BREAKFAST!!
