Which theory explains language development as unfolding with cognitive maturation through stages?

• A. Cognitivist
• B. Piaget's Cognitive Development Theory
• C. Skinner's Behaviorist Theory
• D. Concrete Operations

Answer: (B)

Language development unfolds as a child’s thinking matures through distinct stages. Piaget's Cognitive Development Theory describes this process, proposing that cognitive growth happens in ordered stages—sensorimotor, preoperational, concrete operational, and formal operational—each bringing new ways of thinking and symbol use. Language emerges as children’ s mental representations become more complex, with early communication rooted in concrete action and gradually becoming symbolic, social, and abstract as thinking advances. In the preoperational stage, for example, children start using words to represent objects and ideas, while later stages support more precise grammar, logical connections, and hypothetical language. Because the development is tied to maturational stages of cognition, this framework best explains why language abilities become more sophisticated as thinking changes. Behaviorist theories, by contrast, emphasize learning through reinforcement rather than internal stage-based cognitive growth, and a broad cognitivist view focuses on mental processes without the specific stage-by-stage progression. Also, one of Piaget’s stages—the concrete operational stage—describes a phase of thinking rather than a theory itself.
