Autism & Developmental

No Differences in Code-Related Emergent Literacy Skills in Well-Matched 4-Year-Old Children With and Without ASD.

Westerveld et al. (2020) · Journal of autism and developmental disorders 2020
★ The Verdict

When 4-year-olds with autism are matched on language, their early literacy looks typical.

✓ Read this if BCBAs in preschool or early-intervention classrooms.
✗ Skip if Clinicians who only serve non-verbal or older school-age clients.

01Research in Context

01

What this study did

The team compared 4-year-olds with and without autism. They matched each child on language age and thinking skills. Then they tested phonics, letter names, and asked parents about bedtime books.

02

What they found

Kids with autism scored the same as typical kids on every early-reading task. Parents in both groups reported similar story-time habits. The diagnosis alone told us nothing once language was equal.

03

How this fits with other research

Åsberg Johnels et al. (2019) followed children for five years. They showed that weak oral language at age 3, not autism, predicts poor reading later. The new study lines up: match language and the gap closes.

Ferguson et al. (2021) looked at the same preschool age. They found kids with autism often score higher on written than spoken tests. Together the papers say: check print skills early; they may be a strength.

Sorenson Duncan et al. (2021) pooled 26 studies. Word reading and oral language helped school-age kids with autism equally. The preschool null result now makes sense—both skills were already even.

04

Why it matters

Stop assuming autism means reading trouble. Screen language level first. If it matches the child’s age, teach letters and sounds with confidence. Use the child’s possible written-communication strength to boost spoken language. Match, then move ahead.

03Original abstract

This study used data from a prospective community-based sample and compared the code-related emergent literacy skills (phonological awareness and letter knowledge) of 4-year-old children with ASD (n = 36) to their peers without ASD (n = 36), matched for age, gender, socio-economic status, language ability, and nonverbal cognition. We also compared groups on parent-reported home literacy measures, including the amount of time their child enjoyed being read to. There were no significant group differences in emergent literacy, indicating that an ASD diagnosis was not related to children's emergent literacy performance. We found no group differences in parent-reported home literacy experiences. This highlights the need for careful consideration of factors beyond ASD traits that may influence literacy outcomes in this population.
