Inhibitory function in nonretarded children with autism.
Inhibition is intact in most autistic kids—gender, stimulus type, and pacing explain when problems appear.
01Research in Context
What this study did
The team tested two classic inhibition tasks on kids with autism who had normal IQ.
One task asked children to stop a button press when a beep sounded.
The other task made kids ignore a flashed word so they could name the ink color.
They compared scores to same-age typical kids.
What they found
Both groups scored the same.
Autistic kids stopped and ignored just as well as controls.
The authors wrote: inhibition itself is spared; look elsewhere for executive problems.
How this fits with other research
Cramm et al. (2009) repeated the null result with social pictures and added a twist: accuracy only dropped when the pictures crawled by slowly, hinting boredom, not broken inhibition.
Amore et al. (2011) seem to disagree: they found slower stopping in autistic girls but not boys.
The clash disappears when you split by gender; boys drive the 1997 null average.
Lee et al. (2024) pushed further: inhibition stays intact for cartoon faces yet collapses for real emotional faces, showing the deficit is stimulus-specific, not global.
Why it matters
Stop blaming every executive stumble on poor inhibition.
When a learner stalls, check task speed, gender, and stimulus type first.
Keep social drills brisk and use real photos, not cartoons, when you need true emotion practice.
If the learner is a girl, give extra response-time support; the data say she may need it.

03Original abstract
This study examined inhibitory function in nonretarded children with autism (n = 13) and normally developing controls (n = 13) matched on age and IQ. Tasks measuring motor and cognitive components of inhibition were administered to both groups. On the Stop-Signal paradigm, children with autism were able to inhibit motor responses to neutral and prepotent stimuli as well as control subjects. On the Negative Priming task, the groups were equally capable of inhibiting processing of irrelevant distractor stimuli in a visual display. Results suggest that at least two components of inhibition are spared in individuals with autism, standing in contrast to flexibility and other executive deficits that have been found in previous studies. These findings may help distinguish children with autism from those with other neurodevelopmental conditions that involve executive dysfunction.
