Which theory posits that L1 and L2 are interdependent and that concepts transfer between languages?

• A. BICS
• B. CALP
• C. SUP
• D. CUP

Answer: (D)

The idea being tested is that language knowledge in L1 and L2 shares a common foundation. Common Underlying Proficiency holds that cognitive and conceptual understandings live in one shared store, so when you learn something in your first language, that same knowledge can support learning in a second language. Because of this shared base, concepts, strategies for thinking, and even literacy skills can transfer between languages, helping you tackle new content in L2 more efficiently. This stands in contrast to the notion that L1 and L2 are separate systems, which would suggest little or no transfer between languages. Also, the other terms describe different aspects of language use: BICS refers to everyday conversational ability, and CALP to academic language proficiency, neither of which address the interdependence of L1 and L2 concepts.
