4. What did Dr Deb Roy try to achieve in his house?

He tried to find out how can Human Being communicate with language, so he started when we first learn how to talk, as a Child. He knew that to discover how we talk he had to see and hear the children 24 hours a day 7 days a week to examine every detail. Until he was the age of 3. (3:40 on Video.)

5. Which are the earliest stages in language for a child?

The typical development stages of language are that a Child will go from babbling to using single words usually as a request or need he is looking for. And then they will start a two-word stage, which is putting to words together like "more milk", very quickly, the child will be talking complex sentences. (5:30 on Video)

6. What external and internal factors made the data recollected in the experiment into something they could use?

He focus on the two-word stage, which will be normally seen in the birthday number 2 or 3. They had to see who said what, annotations of where these people were. The language of the child was influenced by the repetition of the words by the parents, and who said it, the relationship between who said what. The child would put more atention on one of the words the parents said. If he liked more the mother he could put more atention on what the mother was talking about. (6:20 on Video.)
