Two intact executive capacities in children with autism: implications for the core executive dysfunctions in the disorder.
Autistic learners show solid executive skills when rules are clear and they can speak—so keep rules explicit and allow verbal mediation.
01Research in Context
What this study did
Webb et al. (1999) tested two executive tasks in autistic children.
One task had clear rules and let kids answer out loud.
The other used strange new rules and silent pointing.
They compared scores to same-age peers.
What they found
Autistic kids matched peers when rules were clear or speech was allowed.
They slipped only when rules felt random and no talking was allowed.
The study says executive trouble is not across-the-board.
How this fits with other research
Laurie-Masi et al. (2022) saw the same pattern in adults.
Autistic adults learned cue links fine but lagged when the links flipped.
Mayra et al. (2025) also found slower category learning in autistic adults when rules were fuzzy.
Muller Spaniol et al. (2018) looks opposite at first glance.
Their neurotypical adults with high autistic traits actually ignored distractors better, not worse.
The gap fades when you note Mayra studied traits in typical adults, not diagnosed kids.
Different group, different task, same theme: attention rules matter.
Why it matters
You can spare executive load by making rules plain and letting kids talk through steps.
Write short, spoken scripts for new routines.
If you must change a rule, signal it early and give extra flip-practice trials.
Check task language demands before calling a failed trial an executive deficit.

03Original abstract
Many studies have shown that children with autism perform at a much lower level than control subjects on tests of executive functioning, defined as tasks requiring subjects to hold information in mind while suppressing a prepotent response. These tasks have invariably required subjects to (a) follow arbitrary and novel rules and (b) make a nonverbal response. We report that when one of these features is absent, children with autism are not impaired relative to controls. They perform at a similar level to normally developing children on the "tubes" task (containing no arbitrary and novel rules) and on the day/night task (in which the output is verbal). Results are consistent, at least, with the hypothesis that children with autism are challenged by executive tasks because they are unlikely to encode rules in a verbal form.
