By looking at text A, we can gather that Tim is in the telegraphic stage of language development. This is evidenced through Tim's use of declarative sentences which are not yet complex enough to be classed as post-telegraphic stage language. Tim is also able to use a variety of concrete nouns  like 'daddy', 'cot' and 'crocodile, however his language is fairly limited to concrete nouns rather than abstract. Additionally as well as using concrete nouns in his speech, he is also able to use pre-modifiers such as 'big crocodile' to make his utterances more detailed, which will ensure that he is understood. In Tim's vocabulary, he does not use pronouns when referring to his sister or his father but understands that the third person singular pronoun 'she' refers to his sister.

When Tim first said the concrete noun 'crocodile' he has trouble saying it which results to gran re-casting the concrete noun and giving him help and support saying it correctly. This supports the Behaviorist Theory

Social interaction is key to Child Language Acquisition as we can infer from this transcript. This transcript involves a boy named Tim who is 3 years, 10 months old. He is interacting with his family. I would firmly place Tim within the Telegraphic stage, evident to this decision; we know that he would be placed within this stage due to the fact that there is enough information for the sentence’s to make sense.This stage includes three or four word sentences, of which Tim demonstrates clearly, “that’s just a little one.”  The most common words are the words of this stage include social interaction. For example, please, bye and no. Again Joey demonstrates this in the transcript "no (3.0) not in the tummy (2.0) get out." I have firmly placed Tim within the Telegraphic stage, as opposed to placing him between stages due to the fact that he is mainly speaking in declarative sentences, "and there's a hole is Izzy's (.) cot (1.0)", his sentences aren't complex enough to be placed between the Telegraphic and Post-Telegraphic.

At three years and ten months, Tim is able to speak and interact verbally with adults in a more mature way than a child who is in the one word stage or two word stages could. However, it becomes clear that there are immature themes within his speech. An example of this is the prevalence of both declarative sentences and nouns, both concrete and proper. The declarative sentences such as ‘and Izzy’s going in the cot’ show us that Tim’s thinking is straightforward and to the point, which is standard for children his age. The concrete nouns, both ‘cot’ and ‘hole’ are repeated along with the sentence repetition, and the proper noun ‘Izzy’ is used instead of the pronoun ‘she’, which also applies to ‘daddy’. He can clearly understand pronouns as gran refers to Izzy as ‘she’ and he comprehends it, however he does not use them himself. This indicates his knowledge of language is vaster than what he uses himself. 

Text A is a conversation between Tim and his grandmother. From the transcript we can see that Tim is in telegraphic stage because of his use of declarative sentences such as ‘there's a hole in Izzy’s cot’.This shows us that Tim can say simple things clearly and efficiently but however it seems that he is not complex enough to be classed that he is in the post telegraphic stage because he has mainly used declarative sentences and he has not used any complex sentences.

Social interaction is an important factor in child language acquisition. From Text A, we can gain an understanding that Tim is in the Telegraphic stage of language development. This is evident in his repeated use of concrete nouns. For example, Tim uses “crocodile”, “bedroom” and  “cot” to express himself. Clearly, Tim has not developed his use of different types of nouns. This proves that he is in the Telegraphic stage. Furthermore, Tim struggles to pronounce the concrete noun "crocodile", highlighting that his grammar has not fully developed. In contrast to this, Tim's use of the pre-modifying adjective "big", gives us a sense that he is able to express and comprehend size. This rare use of language may offer that he is starting to develop Post-Telegraphic stage language features, although he is firmly in the Telegraphic stage, as his use of concrete nouns and mainly declarative sentences, such as "there's a hole in Izzy's (.) cot" confirms his language hasn't developed into the final stage of Child Language Acquisition.

By looking at Text A which is a conversation between Tim, his mum and his gran we can see that Tim is in the telegraphic stage of language acquisition. This is seen with his use of declarative sentences such as; “Izzy’s going in the cot”. They are mostly present tense. But he is not any further because the majority of his words are concrete nouns such as “crocodile” and his language is not complex enough to exceed the telegraphic stage and go into post telegraphic lanuage. It is clear that Tim has not yet developed the full use of language to move onto complex sentences and use of many nouns other than concrete ones.
