A system for self expression and communication also it is a capacity for language with which each newborn is endowed
Basic requirements (during the first two or three years of development
Need
interaction with other language users
To be physically capable of sending and receiving sound signals in language
The acquisition schedule
The language acquisition schedule has the same basis as the biologically determined development of motor skills
Caregiver speech
The simplified speech style adopted by someone who spends a lot of interacting with a young child
For example
Simplified words with repeated simple sounds and syllables
(Tummy,nana)(choo choo, poo poo, pee pee,wawa
Is
Cooing
(4-5months )
And
The earliest use of speech-like sounds
Particularly high vowels similar to (i) and (u)
Babbling
6-8months
Is the production of a number of different vowels and consonants,as well as combinations
Such as
(Ba-ba-ba)(ga-ga-ga)
Later babbling stage has more ,complex syllable combinations.Nasal sounds also become more common
(Ma-ma,da-da,
The one-word stage
12-18 months
Children begin to produce a variety of recognizable single-unit utterances
Is characterized
By speech in which single terms are uttered for everyday objects
Such as
Milk,cookie,cat,cup and spoon
The two-word stage
18-20months
Two distinct words used together
Vocabulary
Moves beyond fifty words
For example
Baby chair,mommy eat,cat bad.
By the age of two,wether the child is producing 200 or 300 distinct words he or she will be capable of understanding five times as many.
Telegraphic speech
2-2 1/2 years old
This is characterized by strings of words(lexical morphemes) ,grammatical inflections begin to appear in some of word-forms and simple prepositions
Such as
(This shoe all wet,cat drink milk,daddy go bye-bye)
By three the vocabulary has grown to hundreds of words and pronunciation has become closer to the form of adult language
At this point
It is worth considering what kid of influence, if any, the adults have in the development of the child's speech
The acquisition process for
The child's linguistic production appears to be mostly a matter of trying out constructions and testing wether they work or not
