Explain the Single-System and Dual-System Hypotheses for Bilingualism

Question

Examlex · Accepted Answer

The Answer is The single-system and dual-system hypotheses are two competing theories that attempt to explain how bilingual individuals process and produce language.

The single-system hypothesis posits that bilinguals have a single language system that is shared between their two languages. According to this theory, both languages are stored and processed in the same mental lexicon, and there is no strict separation between the two languages. Proponents of the single-system hypothesis argue that bilinguals access and use their languages in a similar way to monolinguals, and that the two languages are interconnected and influence each other during language processing.

On the other hand, the dual-system hypothesis suggests that bilinguals have two separate and distinct language systems, with each language being stored and processed independently. This theory proposes that bilinguals have separate mental lexicons for each language, and that the two languages are processed and produced using different cognitive mechanisms. Proponents of the dual-system hypothesis argue that bilinguals have the ability to switch between their languages, and that the two languages are kept separate in the mind to avoid interference and confusion.

Both hypotheses have received support from various research studies, and the debate between the two theories is ongoing. Some researchers argue that the single-system and dual-system hypotheses are not mutually exclusive, and that bilingual language processing may involve a combination of both systems depending on the context and the individual's language proficiency. Overall, the single-system and dual-system hypotheses provide valuable frameworks for understanding the complex nature of bilingual language processing.
