Which term is used to describe the period during which language can be acquired rapidly, often cited as 'critical age'?

• A. Critical Age Theory
• B. Navigational Theory
• C. Socio-Cultural Theory
• D. Static Learning Theory

Answer: (A)

The idea being tested is the window in early development when language can be learned most easily. The term used to describe that window is the critical age theory, reflecting the notion of a defined period during which language input leads to rapid acquisition. This is the best choice because it directly names a time-limited phase in which language learning is most efficient, a concept supported by observations in first-language development and differences in second-language mastery before and after puberty. Other options point to unrelated ideas (navigation in learning, social interaction-based approaches, or fixed/static learning models) and don’t capture the idea of a specific developmental window for rapid language acquisition.
