Investigating the Use of World Knowledge During On-line Comprehension in Adults with Autism Spectrum Disorder.

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

Adults with autism understand text well, but need a brief pause to spot subtle real-world errors.

✓ Read this if BCBAs teaching reading or life-skills classes to fluent readers with ASD.
✗ Skip if Clinicians focused on non-readers or preschool language.

01Research in Context

01

What this study did

Bassett-Gunter et al. (2017) watched adults with autism read short stories on a screen.

The stories held tiny world-knowledge errors like "the thief used a spoon to pick the lock."

Eye-tracking cameras timed how fast readers spotted the odd word.

02

What they found

Adults with autism caught obvious theme errors just as fast as typical peers.

They were slower only when the error needed quick world-knowledge checks.

The delay was milliseconds, but it showed up on every eye trace.

03

How this fits with other research

Espín-Tello et al. (2017) saw the same slow-down in school kids answering inference questions.

Both studies used eye-tracking and found intact accuracy with extra time.

Laposa et al. (2017) tested children with ambiguous sentences and also saw mixed results.

Together the papers say speed, not skill, differs across ages in ASD readers.

Fleury et al. (2018) looked long-term and found reading levels stay behind peers.

That seems to clash, but P et al. measured overall growth while L et al. caught moment-by-moment processing.

Both can be true: small online delays may add up to larger gaps over years.

04

Why it matters

When you run reading programs, give adult clients a beat longer to judge odd facts.

Pause after implausible lines and ask, "Does that make sense?"

The extra second lets world knowledge kick in and keeps comprehension intact.

03Original abstract

The on-line use of world knowledge during reading was examined in adults with autism spectrum disorder (ASD). Both ASD and typically developed adults read sentences that included plausible, implausible and anomalous thematic relations, as their eye movements were monitored. No group differences in the speed of detection of the anomalous violations were found, but the ASD group showed a delay in detection of implausible thematic relations. These findings suggest that there are subtle differences in the speed of world knowledge processing during reading in ASD.
