Do cognitive training applications improve executive function in children with adverse childhood experiences? A pilot...

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Technology

Background:

• Adverse Childhood Experiences (ACE) significantly impede the development of executive functions (EF), including inhibitory control, working memory, and cognitive flexibility.
• These core EF skills are foundational for complex abilities like problem-solving, reasoning, and planning, impacting long-term life outcomes.
• The need for effective interventions to mitigate the negative effects of ACE on childhood cognitive development is critical.

Purpose of the Study:

• To investigate the efficacy of Computerized Cognitive Training Applications (CCTA) in enhancing executive function (EF) in school-aged children (6-11 years) with a history of ACE.
• To assess the impact of CCTA on specific EF components, particularly working memory, inhibitory control, and cognitive flexibility.
• To explore the potential of CCTA as a scalable intervention within school settings for children exposed to adversity.

Main Methods:

• A pilot study employing a pre-post-test, between-subject experimental design with an experimental group and a placebo-control group.
• Participants (n=32) were children aged 6-11 with an ACE score of 4+ based on parent-report questionnaires.
• Executive function was assessed using the Behavior Rating Inventory of Executive Function (BRIEF) to measure behavioral changes (far-transfer), with groups matched for age and prior academic attainment.

Main Results:

• Computerized Cognitive Training Applications (CCTA) demonstrated a statistically significant positive effect on overall executive function.
• Working memory showed a particularly notable improvement in the experimental group compared to the control group.
• The findings suggest that CCTA can positively influence behavioral manifestations of executive function in children with ACE.

Conclusions:

• This pilot study provides preliminary evidence supporting the effectiveness of CCTA in improving executive function, with a notable impact on working memory, in children aged 6-11 with adverse childhood experiences.
• Computerized cognitive training applications represent a promising avenue for intervention to support cognitive development in vulnerable populations.
• Further research with larger sample sizes is warranted to confirm these findings and establish the long-term benefits of CCTA for children affected by ACE.
