In autism, language development: which statement is supported?

• A. All speakers become fluent
• B. About half never develop verbal skills
• C. Most develop perfect high-level speech
• D. Some develop fluency only in writing

Answer: (B)

Language development in autism is highly variable, with many individuals facing significant expressive challenges. A substantial portion do not develop functional spoken language, or do so only with great difficulty, and some rely on alternative communication methods. This pattern is why the statement that about half never develop verbal skills is the best-supported choice: it reflects the meaningful minority who remain nonverbal despite intervention and support, while others may progress to varying degrees of spoken language or use AAC to communicate.

It's also important to keep in mind that even among those who do speak, language can be uneven—receptive language, social use, fluency, and prosody can all differ from typical development. Some people may become fluent in daily conversation, but still struggle with pragmatic language or nuanced conversation.

The other options don’t fit as well because many individuals do not become fluent speakers, “perfect” high-level speech is not typical, and fluent literacy alone is not the standard outcome for spoken language development in autism.
