Rapid Linguistic Ambiguity Resolution in Young Children with Autism Spectrum Disorder: Eye Tracking Evidence for the Limits of Weak Central Coherence.
Verbally-able young children with autism resolve word ambiguity as fast as peers, so weak central coherence does not apply across the board.
01Research in Context
What this study did
Researchers watched the eyes of 7-year-olds with strong vocabularies while they heard sentences like "He dug with the spade." The word "spade" can mean shovel or playing card. Kids looked at pictures on a screen. Fast looks to the shovel picture show they used the sentence to pick the right meaning.
The team compared kids with autism to typical peers. They wanted to test the idea that children with autism have "weak central coherence" and cannot use context to disambiguate words.
What they found
Both groups picked the correct meaning just as quickly. Eye-tracking showed no delay in children with autism. The data contradict the weak central coherence account for verbally-able children.
Strong vocabulary, not diagnosis, predicted speed of resolution.
How this fits with other research
van Schrojenstein Lantman-de Valk et al. (2006) seems to disagree. They found weaker coherence in adolescents with autism plus intellectual disability. The clash disappears when you note the target study tested verbal 7-year-olds while J et al. tested older teens with ID. Coherence differences may only show up when IQ is lower.
Laposa et al. (2017) extends the same ambiguity task to reading in 8- to 14-year-olds. They also see intact context use, but lingering interference afterward. The target’s null finding holds for the moment of resolution; later processing may still wobble.
López et al. (2008) and Hagopian et al. (2005) had already chipped away at the single "weak coherence" idea. The new eye-tracking evidence pushes the field toward a subtler view: context skills are spared when language is strong.
Why it matters
Stop assuming every child with autism needs context drilled. If the learner has age-appropriate vocabulary, you can teach idioms, metaphors, and multiple-meaning words at grade level. Use eye-gaze apps to check real-time understanding during story time; quick looks to the right picture mean the sentence context landed. Save extra support for kids with both autism and low verbal scores—that subgroup may still struggle.

03Original abstract
Individuals with autism spectrum disorders (ASD) have often been reported to have difficulty integrating information into its broader context, which has motivated the Weak Central Coherence theory of ASD. In the linguistic domain, evidence for this difficulty comes from reports of impaired use of linguistic context to resolve ambiguous words. However, recent work has suggested that impaired use of linguistic context may not be characteristic of ASD, and is instead better explained by co-occurring language impairments. Here, we provide a strong test of these claims, using the visual world eye tracking paradigm to examine the online mechanisms by which children with autism resolve linguistic ambiguity. To address concerns about both language impairments and compensatory strategies, we used a sample whose verbal skills were strong and whose average age (7; 6) was lower than previous work on lexical ambiguity resolution in ASD. Participants (40 with autism and 40 controls) heard sentences with ambiguous words in contexts that either strongly supported one reading or were consistent with both (John fed/saw the bat). We measured activation of the unintended meaning through implicit semantic priming of an associate (looks to a depicted baseball glove). Contrary to the predictions of weak central coherence, children with ASD, like controls, quickly used context to resolve ambiguity, selecting appropriate meanings within a second. We discuss how these results constrain the generality of weak central coherence.
