Brief report: a comparison of statistical learning in school-aged children with high functioning autism and typically developing peers.
High-functioning autistic children learn hidden sound patterns as well as peers, so language delays come from elsewhere.
01Research in Context
What this study did
Urgelles et al. (2012) watched high-functioning autistic kids and typical kids play a computer game.
The game hid patterns in sounds. Kids had to guess what came next.
No one told them the rules; the researchers wanted to see if the autistic kids could still pick up the hidden patterns.
What they found
Both groups learned the sound patterns equally well.
Scores on the game did not line up with the kids’ current language test scores.
This means the brain skill that spots patterns is not the same skill that builds spoken language.
How this fits with other research
Baixauli et al. (2016) looked at 24 studies and found that high-functioning autistic kids tell weaker stories. That seems opposite to Jessica’s null result, but the tasks differ: storytelling is open-ended and social; the game was silent and rule-based.
Sipes et al. (2014) followed similar kids and showed that language level, not diagnosis, predicts prosody gains. Both papers agree that language ability inside the autism group matters more than the autism label itself.
Lifshitz et al. (2014) found that autistic kids use less inner speech during tricky tasks. Together with Jessica’s finding, it hints that different learning routes—implicit versus self-talk—can each stay flat or strong in autism.
Why it matters
If a child’s language is delayed, do not assume the basic learning machine is broken. You can still use pattern-based teaching, like serial mand training or artificial grammar games, because the kids can track probabilities just fine. Save extra practice for real-language use—story retells, conversation—not for the hidden rules underneath.

03Original abstract
Individuals with autism spectrum disorders have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning is potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to transitional probabilities between speech sounds. This study investigated the relationship between implicit learning and current language abilities in school-aged children with high functioning autism and a history of language delay (n = 17) and in children with typical development (n = 24) using a well-studied artificial language learning task. Results suggest that high functioning children with autism (HFA) and TD groups were equally able to implicitly learn transitional probabilities from a lengthy stimulus stream. Furthermore, task performance was not strongly associated with current language abilities. Implications for implicit learning research in HFA are discussed.
