Executive function and academic achievement in primary - grade students with Down syndrome.

Will et al. (2017) · Journal of intellectual disability research : JIDR 2017
★ The Verdict

Executive function skills predict school success in Down syndrome, but the links differ from typical kids—so choose EF targets that match the subject you teach.

✓ Read this if BCBAs writing IEP goals or academic programs for primary-grade students with Down syndrome.
✗ Skip if Clinicians who only serve adults or clients without developmental disabilities.

01Research in Context

01

What this study did

Morrison et al. (2017) compared kids with Down syndrome to mental-age-matched peers without disabilities.

They gave each child short tests of executive function and early reading and math.

The goal was to see which EF skills line up with school marks in Down syndrome.

02

What they found

Children with Down syndrome showed a different EF-to-achievement map than their peers.

For example, a skill that helped typical kids read did not always help kids with DS.

The pattern tells us to pick EF targets that matter most for this group.

03

How this fits with other research

Hong et al. (2021) pooled 57 studies and found large EF deficits in Down syndrome.

Their meta-analysis backs the target paper: EF is weak, so we must teach it head-on.

Moya et al. (2022) later showed the same EF skills also drive daily living skills.

Together the three papers say: boost working memory and shifting in DS and you may lift both grades and life skills.

Freeman et al. (2015) saw that weaker motor scores sat next to weaker EF scores.

The target study did not test motor skills, so adding movement games might give an extra push.

04

Why it matters

When you write an IEP for a student with Down syndrome, list the EF domains that link to the academic goal.

If the study says shifting predicts math in DS, teach shifting games before multi-step problems.

Skip broad EF drills that help typical kids but show no payoff here.

Match the skill to the subject and you save time and see faster gains.

03Original abstract

BACKGROUND: Executive function (EF) plays a critical role in academic outcomes in typically developing children, but the contribution of EF to academic performance in Down syndrome (DS) is less well understood. This study evaluated differences in early academic foundations between primary school aged children with DS and non-verbal mental-age matched typically developing (TD) children. Additionally, the contribution of EF domains to academic outcomes was evaluated in each group. METHOD: Participants with DS (n = 29) and mental-age matched TD participants (n = 23) were administered the Woodcock Johnson- III NU Tests of Academic Achievement, as well as a laboratory-based EF battery, including measures of working memory, shifting, inhibition and object-planning. RESULTS: Findings indicated a difference in early academic foundations profile between children with DS and mental-age matched TD children. Patterns of EF contributions towards academic outcomes were also observed across groups. CONCLUSIONS: Aspects of EF are critical to academic achievement in DS but differentially so relative to typical development. Implications for educational instruction are discussed.
