Why do Deaf or hard-of-hearing students often experience language delays?

• A. Genetic factors
• B. Environmental limitations for language access
• C. Lack of motivation
• D. Poor schooling

Answer: (B)

Language development depends on having regular, accessible language input from an early age. When Deaf or hard-of-hearing students don’t have consistent access to a fully accessible language—whether through a natural sign language, or spoken language with supports like interpreters, captions, or amplification—their exposure to language is limited. That limited access can slow the acquisition of vocabulary, grammar, and pragmatic skills during critical developmental periods, leading to language delays. Genetic factors relate to hearing loss itself but don’t by themselves explain language delay when accessible language is provided. Lack of motivation or poor schooling can affect language growth, but they don’t account for the common pattern seen when language input isn’t readily available; the environmental barrier to language access is the central issue.
