Can Children with Autism Spectrum Disorders Learn New Vocabulary From Linguistic Context?

Lucas et al. (2017) · Journal of autism and developmental disorders 2017
★ The Verdict

Kids with autism learn words best when you give both story context and a clear definition.

✓ Read this if BCBAs teaching vocabulary to preschool and elementary students with autism.
✗ Skip if Clinicians focused only on motor or daily-living skills.

01Research in Context

01

What this study did

Sutherland et al. (2017) asked if kids with autism can pick up new words from the surrounding talk alone.

They compared two quick teaching styles: hearing the word in a story line versus hearing a clear definition.

Children with autism and typical peers joined; the team tracked both receptive and expressive gains.

02

What they found

Both groups learned new words.

Story context helped kids understand the word when they heard it later.

A short, clear definition helped kids actually say the word themselves.

Children with stronger language skills learned more; those with autism and language impairment learned the least.

03

How this fits with other research

Dixon et al. (2008) showed kids with autism can also learn extra words just by watching peers in small-group lessons.

Bosseler et al. (2003) used a computer tutor to give explicit definitions and got strong expressive gains, matching the new finding.

Adams et al. (2024) saw no special boost from changing input in toddlers, seeming to clash with the 2017 result.

The gap is age and task: toddlers tracked moment-to-moment speech, while older kids in Rebecca’s study had time to link whole story lines to new words.

04

Why it matters

Use both routes in your session. Read the story first so the child hears the new word in rich context. Then pause and give a one-sentence definition while showing the item. This pair builds both understanding and spoken use in the same five-minute slot.

03Original abstract

This study investigated whether children with autism spectrum disorders (ASD) can learn vocabulary from linguistic context. Thirty-five children with ASD (18 with age-appropriate structural language; 17 with language impairment [ALI]) and 29 typically developing peers were taught 20 Science words. Half were presented in linguistic context from which meaning could be inferred, whilst half were accompanied by an explicit definition. Children with ASD were able to learn from context. Condition did not influence phonological learning, but receptive semantic knowledge was greatest in the context condition, and expressive semantic knowledge greatest in the definitional condition. The ALI group learnt less than their peers. This suggests that at least some vocabulary should be taught explicitly, and children with ALI may need additional tuition.
