Insights

Adaptive working memory training (WMT) did not show superior effects compared to placebo in children with borderline intellectual functioning and neuropsychiatric disorders. Both groups showed improvements, suggesting benefits from structured learning environments.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Child Psychiatry

Background:

  • Children with borderline intellectual functioning (BIF) and co-occurring ADHD/ASD often exhibit poor working memory, lower IQ, and maladaptive behaviors impacting development.
  • Limited evidence-based treatment options exist for this population.
  • This study addresses the need for effective interventions targeting cognitive and behavioral deficits.

Purpose of the Study:

  • To investigate if adaptive computerized working memory training (WMT) improves non-trained visuospatial working memory tasks more than a non-adaptive placebo WMT in children with BIF and neuropsychiatric disorders.
  • To assess near-transfer, far-transfer, and behavioral outcomes as secondary measures.

Main Methods:

  • A triple-blind, placebo-controlled randomized clinical trial involving 72 children (aged 10-13) with BIF and comorbid ADHD/ASD.
  • Participants completed 25 sessions of either adaptive Cogmed WMT or a non-adaptive placebo version over 5 weeks.
  • Outcomes were measured immediately post-intervention and at 6-month follow-up.

Main Results:

  • No significant difference in improvement on the primary outcome (non-trained visuospatial WM task) between adaptive WMT and placebo WMT groups.
  • Secondary and tertiary outcomes also showed no significant superior improvement in the adaptive WMT group.
  • Both groups demonstrated changes over time, indicating potential benefits from the training structure itself.

Conclusions:

  • Adaptive WMT did not demonstrate superior training effects compared to a non-adaptive placebo in children with BIF and neuropsychiatric disorders.
  • Observed changes in the placebo group suggest that structured learning environments may facilitate neurocognitive and coping strategy improvements.
  • Further research is required to identify specific effective training elements and long-term effects for this population.
