Before we learn anything about learning language or making any extensive theory about human communicative behavior, it is important that we understand how human first acquire language. After years of endless research and continuous studies, there is still no theory that is able to explain all human languages. Scientists as well as linguists and psychologist have held countless researches through the centuries in finding the mystery underlying language acquisition. It has baffled us all, in general, how a human child produces his or her first word, puts meanings into it and later constructs even longer sentences from infinite numbers of words to send out a certain message. This has subsequently driven scientists to study the way human brain works. A number of theories have since been deduced to fill in the blank for the sake of knowledge.
In the beginning of the study, it was believed that a child first learns to speak through imitation and induction. Language acquisition was believed to be similar like any other forms of behavior; it was picked up through impersonation from adults and the environment encircling the child. Children were believed to observe the people around them and make their own induction, before they gradually begin to make their first utterances. In this case, language learning was thought to be subjected to the culture of each child, thus happens differently through different cultures. For a while, this theory was settling, while researchers continuously sought more consoling answers. But later, an incessant study in this area has driven the researchers to find other explanation for language acquisition for children. This is triggered by their finding that language development amongst children is strikingly similar across cultures. Therefore, the researchers focus on these possible similarities in the hope of finding a definite answer in language acquisition.
However, this paper does not intend to focus on the similarities.
