Cognitive training as a resolution for early executive function difficulties in children with intellectual disabilities.

Austin et al. (2015) looked at every paper that tried to boost executive function in kids with intellectual disability. They only kept studies that used computer games or table-top drills called cognitive training.

The team graded each study for quality. They checked if kids were picked at random, if trainers were blind to goals, and if gains lasted after sessions ended.

Most trials had weak designs. Many lacked control groups or follow-up tests. Because of these holes, results bounced all over the place.

The authors say we cannot trust any program yet. Better studies must come before schools or clinics buy cognitive-training packages.

Sutton et al. (2022) pooled 26 studies and found people with ID do score lower on EF tasks than mental-age peers. That meta-analysis used stricter rules, so its small but clear deficit adds weight to the call for tighter methods.

van Wingerden et al. (2014) showed kids with ID can decode text on level yet still fail at reading between the lines. Their quasi-experiment hints that EF problems are real, which may explain why training gains are hard to capture.

Capio et al. (2013) and Chiviacowsky et al. (2013) both ran clean motor-learning trials with error-reduced or external-focus cues. These RCTs got positive, lasting effects while cognitive-training papers falter, underscoring that design quality, not the kids, drives the muddy EF picture.

Before you buy that shiny brain-training license, demand peer-review evidence that beats the weak set E et al. flag. Spend your budget on well-built ABA or motor-skill programs that already show clear gains, and keep watching for an EF curriculum that finally survives rigorous testing.
