Parsing Heterogeneity of Executive Function in Typically and Atypically Developing Children: A Conceptual Replication and Exploration of Social Function.

The team ran a follow-up study to see if children still sort into three EF skill groups.

They tested kids with and without autism. Then they asked which group had the most social trouble.

Every child landed in one of three EF profiles: strong, average, or weak.

The weak group carried the heaviest social problems, no matter the diagnosis.

Sutton et al. (2022) pooled 26 studies and also saw small EF deficits in people with ID. Their average effect was mild, but C et al. show the real story is the bottom tail — the small “impaired” cluster drags scores down.

Cohen et al. (2018) tracked boys with fragile X for five years. They saw slow EF growth curve by curve. C et al. add the snapshot view: within any single year, those boys would likely land in the impaired cluster and stay there.

Kalliontzi et al. (2022) found that preschoolers with language disorder plus weak EF had the worst language scores. C et al. echo the pattern: weak EF plus any diagnosis equals the biggest social hit.

Stop using “autism” or “typical” as your only label. First map the child’s EF cluster. If the score lands in the impaired group, plan extra social and self-management goals, because that is where peer problems explode.
