In the book 'Lifespan development' the third edition from Bee and Boyd I found out that at the age of 2 1/2 years, a child's average vocabulary at this age is 600 words which increases to 15,000 by the age of 5- 6.This was found by Pinker in 1994.
I also found out that at 3 years old you have acquired the basic tools needed to form sentences and make conversation. This was found out by Bloom in 1991.
This book was published in the USA in 2001
Good - I think the second is much more possible to test/explore than the first idea. How could you do that?
