Brief Report: A Preliminary Study of the Relationship between Repetitive Behaviors and Concurrent Executive Function Demands in Children with Autism Spectrum Disorder.
Repetitive behaviors jump when autistic kids face both stop and switch commands together, not single ones.
01Research in Context
What this study did
The team watched autistic kids do quick games on a tablet.
Each game tested either stopping, switching, or both at once.
They scored how many repetitive movements each child showed during play.
What they found
Kids with more repetitive movements only slipped up when the game asked for stop AND switch together.
Single tasks caused no extra trouble.
The combo demand lit up the link.
How this fits with other research
Iversen et al. (2021) pooled almost 3,000 kids and found medium links between poor EF and more RRBs.
Our 2022 lab result lives inside that big picture, but zooms in on the exact moment two demands collide.
Saunders et al. (2005) saw EF-RRB ties in autistic adults using single tests; our study says the tie hides until demands double, showing why earlier work sometimes came out flat.
Liu et al. (2025) stretched the idea into feeding: executive trouble helps turn RRBs into food refusal or seeking.
Together the papers trace a line from brain games to real-life rigidity.
Why it matters
Check your client’s environment for stacked requests: stop scripting AND change activity.
That combo, not each part alone, may spark flapping, rocking, or escape.
Break tasks into one demand at a time or add supports like visuals or breaks when mixing stop-and-switch rules.

03Original abstract
The present study evaluated the hypothesis that the strength of the relationship between executive function (EF) and repetitive behaviors and restricted interests (RBRI) symptomatology is moderated by the degree to which concurrent demands are placed on multiple aspects of EF. An eye movement task was used to evaluate inhibition and task switching ability (both together and in isolation) in a sample of 22 children with autism spectrum disorder (ASD). The Repetitive Behavior Scale-Revised (RBS-R) was used to assess the severity of RBRI symptoms. Results provide preliminary support for the aforementioned hypothesis. RBS-R scores were significantly correlated with task performance when simultaneous demands were placed on switching and inhibition; however, no such relationship was found for inhibition-only or switching-only task conditions.
