This chapter examines the idea that bilingual proficiency is internally diverse—that is, componential. It shows that the proposed modification to Cummins’s Common Underlying Proficiency Model needs some modification itself and considers Paivio’s Bilingual Dual Coding Model as well as M. Paradis’s Three-Store Hypothesis. It also discusses why one language subsystem does not appear to affect another in certain cases, but prolific interaction seems to occur in other cases. Furthermore, it looks at how language combining and mixing are accomplished in a grammatically systematic way, how language and general cognition appear to be interdependent, maximum imbalance in bilingualism, how bilingual speech constitutes evidence of language separation, and borrowing and codeswitching. Finally, the chapter proposes a model of how two languages are represented in the bilingual, based on an extension of Jackendoff’s Tripartite Parallel Architecture.

Keywords:   bilingual proficiency, Common Underlying Proficiency Model, bilingualism, Bilingual Dual Coding Model, Three-Store Hypothesis, cognition, language separation, borrowing, codeswitching, Tripartite Parallel Architecture
