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. Instead, the focus of his paper would be the theories of first and second language acquisition. This paper will highlight some theories arisen since the debate on a child's language acquisition begins. These theories are brought about in the hope to see the link between each theory and thus to make connections and settle at a probable answer for the mystery of language acquisition. In completing this paper, I would like to thank Dr. Hjh Jamalleah Hj. Ismail for her full guidance and endless support.
