Impact of executive functions on school and peer functions in youths with ADHD.
Among youths with ADHD, poor spatial working memory and planning skills correlate with worse grades, school behavior, and peer relationships.
01Research in Context
What this study did
Chiang et al. (2014) asked if weak executive functions hurt school and social life for teens with ADHD.
They compared youths with ADHD to typical peers. They used tests and parent forms to measure working memory, planning, and real-world outcomes.
What they found
All ADHD groups had lower grades, more school behavior notes, and poorer peer relations than controls.
Poor spatial working memory and weak planning scores were the clearest predictors of these problems.
How this fits with other research
The finding builds on Chiang et al. (2013), which showed only the inattention part of ADHD links to poor planning. The 2014 paper widens the lens and shows those same planning deficits hurt real-life outcomes.
Wang et al. (2018) extends the idea to autism. They found spatial working memory predicts visuospatial skills in both ADHD and ASD, but through different EF routes. This supports tailoring memory training to each diagnosis.
Feng et al. (2025) looked at younger Chinese-speaking children. They also found visuospatial working memory and inhibition deficits drag down reading scores. The EF-academic link now crosses languages and ages.
Why it matters
If you assess a teen with ADHD, probe spatial working memory and planning even when other scores look fine. Weak scores here flag future report-card and friendship trouble. Add brief memory games or planning routines to your behavior plan. A five-minute daily visual-memory warm-up or color-coded planner check can boost both classwork and playground interactions.

03Original abstract
Youths with attention-deficit/hyperactivity disorder (ADHD) are more likely to have social dysfunction at school. The authors explored the role of key executive functions (EF, i.e., spatial working memory and spatial planning) on school and peer functions in 511 youths with persistent ADHD according to the DSM-IV diagnostic criteria and 124 non-ADHD controls without any EF deficits. All the participants were assessed by a semi-structured psychiatric interview to confirm their previous and current diagnosis of ADHD and other psychiatric disorders and by the Spatial Working Memory (SWM) and Stocking of Cambridge (SOC) tasks. The participants and their parents reported the participants' school functions and peer relationships. There were three ADHD subgroups: (1) ADHD with deficits in both SWM and SOC tasks (n=121); (2) ADHD with deficit in either SWM or SOC task (n=185); (3) ADHD without deficits in SWM or SOC task (n=205). All the three ADHD groups, regardless of EF deficits, had lower school grade, poorer attitude toward school work, poorer school interactions, more behavioral problems at school, and more severe problems in peer relationships than non-ADHD controls. Multivariate analyses revealed positive associations between deficit in the SWM task and school and peer dysfunctions, and between deficits in the SOC task and impaired peer interactions. Older age and psychiatric comorbidity also contributed to increased risk of school and peer dysfunctions. Our findings suggest that deficits in EF, such as spatial working memory and planning, might be associated with school and peer dysfunctions.
