Which concept emphasizes a limited period during which language can be acquired effectively?

• A. Critical Period Hypothesis (CPH)
• B. Counterbalance Hypothesis
• C. Declaritive Knowledge
• D. Developmental Features

Answer: (A)

A limited window for language learning is described by the Critical Period Hypothesis. This idea argues that there is a biologically defined period early in life when the brain is especially receptive to language input, making it much easier to acquire phonology, grammar, and overall fluency. Within this window, children often reach near-native competence with relatively natural ease. After this period, neural plasticity gradually decreases, and acquiring new language features becomes harder, particularly in pronunciation and subtle grammar aspects, though substantial progress can still be made with strong exposure and practice.

Other options don’t capture this timing-focused idea. The counterbalance hypothesis isn’t about a biologically constrained period for language learning, and declarative knowledge refers to conscious, fact-like knowledge rather than how language is acquired over time. Developmental features is too broad and doesn’t specify a bounded period for effective language learning.
