Which of the following is an example of a language disorder?

• A. Proficient reading skills
• B. Extensive vocabulary knowledge
• C. Limited vocabulary development
• D. Positive social interactions

Answer: (C)

Limited vocabulary development is indeed an example of a language disorder because it reflects a significant challenge in acquiring and using language effectively. Language disorders can encompass a variety of issues, including difficulties with vocabulary, grammar, or the ability to use language in social contexts. When an individual has a limited vocabulary, it can hinder their ability to express thoughts, understand others, and engage in meaningful conversations. This limitation can also affect academic performance and social interactions, as language skills are essential for communication and learning.

In contrast, proficient reading skills and extensive vocabulary knowledge indicate strong language abilities, not disorders. Positive social interactions also suggest that an individual is successfully using language and communication skills effectively, which is the opposite of what would be expected in a language disorder context. Therefore, limited vocabulary development is the clear indicator of a language disorder among the choices provided.
