Executive Function Skills Are Linked to Restricted and Repetitive Behaviors: Three Correlational Meta Analyses.
Training executive-function skills could directly cut restricted and repetitive behaviors in autistic clients.
01Research in Context
What this study did
The team pooled data from the kids and teens.
Half had autism, half were typical.
They looked at three executive-function skills: set-shifting, stopping yourself, and parent reports.
Then they checked how these scores lined up with restricted and repetitive behaviors.
What they found
Poor executive-function skills went hand-in-hand with more RRBs.
The link was medium-sized and showed up in both groups.
Set-shifting had the strongest tie to rocking, lining up toys, or strict routines.
How this fits with other research
Gandhi et al. (2022) watched Grade 1-2 classrooms and saw the same EF gaps that the meta found.
Their teacher ratings prove the link is visible at school, not just in labs.
Xie et al. (2024) tested working-memory tricks.
They showed that enactment helps kids remember instructions, but autistic kids still gain less.
Together, these studies say EF weakness is real, but you can chip away at it with practice.
Why it matters
You can add brief EF drills to ABA sessions.
Try five quick set-shifting games before play or work tasks.
Track if rocking or hand-flaps drop after the drill.
Small boosts in EF may calm RRBs without heavy meds.

03Original abstract
There is a consensus on the centrality of restricted and repetitive behaviors (RRBs) in the diagnosis of Autism Spectrum Disorder (ASD), yet the origins of these behaviors are still debated. We reconsider whether executive function (EF) accounts of RRBs should be revisited. EF deficits and high levels of RRBs are often pronounced in individuals with ASD and are also prevalent in young typically developing children. Despite this, the evidence is mixed, and there has been no systematic attempt to evaluate the relationship across studies and between task batteries. We examine recent evidence, and in three highly powered random-effects analyses (N = 2964), examine the strength of the association between RRB levels and performance on set shifting, inhibitory control, and parental-report based EF batteries. The analyses confirm significant associations between high levels of the behaviors and poor EF skills. Moreover, the associations remained stable across typical development and in individuals with ASD and across different types of EF measures. These meta-analyses consolidate recent evidence identifying that cognitive mechanisms correlate with high RRBs that are seen in individuals with ASD, as well as in typical development. We propose that the EF account may be critical for guiding future interventions in ASD research. LAY SUMMARY: Restricted and repetitive behaviors (RRBs) are diagnostic criteria for Autism yet also common in typical development, and if they persist over time some can have a negative impact on learning and social acceptance. The present meta-analyses found that high levels of RRBs related to poor performance on set-shifting and inhibitory control tasks, as well as high ratings on parental report scales. Future studies should create interventions that aim to improve these skills as they may help manage challenging RRBs.
