Word fluency in high-functioning autistic children.

Michael (1988) asked high-functioning autistic kids to say as many words as they could in one minute.

They compared the lists to words from kids without autism who were the same age and IQ.

The task had no rules: any word counted, so success depended on quick word retrieval.

The autistic group produced fewer miscellaneous words than the control group.

The gap points to a weak spot in free word retrieval and loose semantic links.

Vladusich et al. (2010) seems to disagree. Their autistic kids learned new categories as well as peers.

The clash fades when you see the tasks: J used open-ended naming; Tony used clear category rules. Kids can sort when rules are given, but struggle when they must invent their own.

McGonigle et al. (2014) extends the same weakness to adults. High-functioning adults also recalled fewer words when told to remember them, showing the issue lasts past childhood.

Karaca et al. (2026) meta-analysis folds fluency into a bigger picture. Across many studies, autistic people show moderate deficits in flexible thinking and planning, the same skills tapped by free word generation.

When you ask a learner to brainstorm, name examples, or tell a story, you are using free word generation. Expect fewer responses and longer pauses from autistic students. Give prompts like categories, pictures, or first letters to jump-start retrieval. Build word banks and visible lists to lower the load. These small scaffolds turn a frustrating task into a doable one.
