I think you might have sent this just to me and not the rest of the
group, BTW.    Since it sounds really cool, you might want to resend
it.   Cheers,

Margaret

This is certainly a rich and varied exchange of 
ideas! Does it seem to anyone else to be a thought experiment?

The goal of my research over the past 30+ years 
has been to devise observational approaches to 
predicting (even by a few months) when a child 
would shift into single word referential 
language. In a longitudinal study of the first 
three years, among 10 middle class normally 
developing children the range of onset was 14 
months to 27 months of age. I did find that a set 
of measures including development of mental 
representation measured in play, use of vocal 
motor schemes (consonants used consistently 
across several months) and (surprisingly) 
communication by "grunts" together predicted this 
transition. These results were published in bits 
over the years and recently brought together in a 
book from Oxford U. Press "How children learn to 
learn language". In addition to differences in 
rate of development, these children also differed 
in breadth of skill at each phase.

Given this variability in a group from a fairly 
coherent cultural group, I fail to see how we 
could ever know whether children were developing 
language "faster" over the decades. This also 
recalls Piaget's comment regarding whether 
cognition could be speeded up. He called this "the American question"!

Fun as a thought experiment, but hard to expect 
an answer. We still do not really know how and 
why language develops as it does.
