Pathological Study Of Language Problems In Bilingualism

In an increasingly diversified and multilingual world, more and more parents have realized that their children are to learn two or more languages. Many have strong support to children growing up with a second or third language. However, different sorts of problems which accompany bilingual development are discussed and pondered deeply both by parents and professionals. Some hold the belief that hearing two or more languages simultaneously will confuse the children and lead to language pathological problems, such as language disorders, delayed language development, or even aphasia. By contrast, others claim that there is no scientific evidence in favor of the former argument and state that bilingualism will be better off for children's linguistic skills.What does the bilingualism exactly mean? Is learning two languages a burden to the child? Will the children mix up the two codes? In order to make these issues clearer, this research re-presents a clear definitive concept of bilingualism and examines the bilingual problems from the perspective of pathology. Researches on the language pathology are mainly performed in language disorders, language delay, or aphasia. The phenomenon of language pathology could result from many reasons, such as biological factors, linguistic aspects, and even non-specific respects at all. Generally speaking, language pathology can be classified into two kinds: organic language disorders and functional language disorders. As a matter of fact, the reasons of language problems are not isolated from the quantity and quality of input, the emotional relationship with parents, as well as speech community to which the children are exposed. For language pathological problems, there are some we can not do anything. On the other hand for other problems we can do something. It is the problems that we can do something that are more important. In the research, Krashen's"i+1"input hypothesis, is used to tackle the quantity and quality of input, and affective filter hypothesis to provide suggestions for the relation between language and emotion. This paper also makes distinction between language pathological problem and speech errors in term of the reason causing them. Through the analysis of the data from the CHILDES according to Chomsky's UG, especially Principles and Parameters-setting, the hypothesis that bilingualism will not lead to language disorder or problems is proved. Further research should be analysis with other linguistic paradigms.
