In Social Speech a conscious effort is made to use the best rules of language to communicate.
The first thing that impressed me about the little girl is that she first assessed my cultural background and selected her English Code (pragmatics) to speak to me.
In that code she selected the words that expressed her thought (semantics) and put them in the proper syntax (grammar); and with clearly enunciated speech sounds (phonemics) she said, “Can I have my doll?”
It was a verbalization with a clear intent to communicate a message and I immediately complied. Now, if you are wondering why I had her doll, that is an anecdote for the final chapter entitled Freud in a Nut Shell.
Piaget suggests that an indication of mental maturity can be gained by computing a ratio of the incidences of Egocentric to Social Speech.
