Which factor is NOT typically associated with faster early vocabulary growth?

• A. Rich and responsive caregiver interaction
• B. Lack of exposure to language
• C. High-quality language input
• D. Early exposure to multiple languages

Answer: (B)

The main idea here is how different kinds of language input and interaction influence how quickly children build their early vocabulary. The factor that does not contribute to faster growth is not having any language exposure at all. When a child isn’t exposed to language, there are far fewer opportunities to hear word forms, learn what words refer to, and practice using them. That missing input slows vocabulary development because words learn best through frequent, meaningful encounters and practice in guiding interactions. By contrast, rich and responsive caregiver interaction accelerates learning: when caregivers label objects, name actions, ask questions, and keep conversations going, children hear more words in meaningful contexts and get immediate feedback that helps map words to meanings. High-quality language input—varied and precise vocabulary, clear articulation, and syntactic richness—expands the child’s linguistic repertoire and understanding of how words work. Early exposure to multiple languages can also support strong language and cognitive development; while a bilingual child might distribute vocabulary across two languages, with sufficient exposure the total vocabulary and the ability to switch between languages are well-supported, and metalinguistic and cognitive benefits can arise in the process. So, lack of exposure to language stands out as not being associated with faster early vocabulary growth, whereas the other factors provide opportunities that foster quicker lexical development.
