seeking a few bibliographic references

[Jeff ALLEN]

I'm looking for bibliographic references on the following 2 points.

1. It has been shown in First Language Acquisition that prosodic 
patterns are learned and produced by children before 
lexical and syntactic structures, and that parents can understand
the speech of children thanks to the intonation when the 
grammatical structure is sometimes undecipherable in
isolation.

2.  50 or so percent of communication is transmitted through
    gestures, facial expression, etc.

Thanks in advance for bibliographic references and possibly very brief
summaries of what is found in the articles/paper/books that you
mention.

Regards,

Jeff
