What is the unitary system hypothesis?
Proponents of the Unitary System Hypothesis (USH) suggest that the bilingual child initially forms only one grammar and one lexicon for both languages that are acquired. This hypothesis is based on the observation that words as well as constructions of one language seem to occur in the other language.
What is dual language system hypothesis?
In contrast, the dual language system hypothesis states that bilinguals have a separate system for the L1 and L2 which they learn right from the start, so both languages can be acquired simultaneously. Research on vocabulary development have generally provided strong support for this theory.
What is bilingual acquisition?
Bilingual children acquire the same proficiency in the phonological and grammatical aspects of their two languages as monolingual children do in their one language, provided they are given regular and substantial exposure to each.
Can two languages be acquired simultaneously?
Simultaneous bilinguals are children who are exposed to more than one language prior to age three. They develop two or more languages equally, or nearly equally, through exposure and frequent opportunities to use each language.
What is the fundamental difference hypothesis?
The fundamental difference hypothesis in language motivation posits that learning a language is fundamentally different from learning other school subjects.
What is interlanguage grammar?
Interlanguage is the type of language or linguistic system used by second- and foreign-language learners who are in the process of learning a target language. Interlanguage pragmatics is the study of the ways non-native speakers acquire, comprehend, and use linguistic patterns or speech acts in a second language.
What is compound bilingual?
A compound bilingual is an individual who learns two languages in the same environment so that he/she acquires one notion with two verbal expressions.
What is the difference between sequential and simultaneous bilingualism?
According to Tabors (1997), simultaneous bilingualism occurs when children are exposed to two languages from a very early age; while sequential bilingualism occurs when a child begins learning a second language after thefirst language is at least partially established.
How does bilingualism contribute to the language development of an individual?
Studies have shown that bilingual children have advantages in terms of understanding the communication needs of their conversational partners. Young bilingual children are sensitive to the fact that they cannot understand someone who speaks a foreign language earlier than monolingual children.
