On the relationship between autistic traits and executive functioning in a non-clinical Dutch student population.

Researchers gave Dutch college students two sets of forms. One form asked about autism traits. The other tested four parts of executive function: planning, working memory, shifting, and inhibition.

All students were neurotypical. No one had an autism diagnosis. The team wanted to see if higher autism-trait scores predicted worse executive-function scores.

They found nothing. Autism-trait scores did not link to any executive-function score. A student could score high on traits and still show top planning or memory.

Only personality traits, like conscientiousness, showed small ties to working memory and shifting. Autism traits alone told us nothing about EF performance in this group.

Dai et al. (2019) looked at younger kids and saw a different picture. In 6- to 9-year-olds, executive function did predict autism-trait profiles, but only when they split the group by gender. The link shows up early in life, just not in young adults.

Trevisan et al. (2016) used the same Dutch student sample and found that higher autism traits did predict poorer college adjustment, especially in pragmatic language. The traits are real and measurable; they simply do not affect EF test scores in this population.

Moss et al. (2009) and Bowen et al. (2012) also tested non-clinical students. They found that high autism traits linked to visual-processing style, not to EF. Taken together, the trait is stable, but its cognitive correlates change with age and task type.

If you screen a college-aged client and see high autism-trait scores, do not assume executive-function deficits. Focus your assessment on personality, language, or visual processing instead. Save EF interventions for clients who show direct EF problems, not trait scores alone.
