Computer-Based Cognitive Training Improves Brain Functional Connectivity in the Attentional Networks: A Study With...

Area of Science:

• Cognitive Neuroscience
• Educational Psychology
• Neuroimaging

Background:

• Working memory (WM) training is a key area of cognitive development research.
• Integrating cognitive training into school routines presents unique implementation challenges and opportunities.
• Understanding the neural underpinnings of cognitive improvements in children is crucial for educational interventions.

Purpose of the Study:

• To investigate the impact of a school-based working memory (WM) training program on cognitive and academic skills in children.
• To examine changes in brain functional connectivity, specifically within attentional networks (ATN), following cognitive training.
• To explore the relationship between enhanced inhibitory control and functional connectivity in specific brain regions like the right middle frontal gyrus (MFG).

Main Methods:

• A computer-based cognitive training program targeting working memory (WM) was implemented by teachers in a school setting.
• Participants were divided into a training group and an active control group.
• Resting-state functional magnetic resonance imaging (fMRI) was used to assess brain functional connectivity before and after the 6-month training period.

Main Results:

• Children in the training group showed significant improvements in cognitive skills (inhibition, non-verbal IQ) and academic performance (mathematics, reading) compared to the control group.
• Brain imaging revealed altered functional connectivity within attentional networks (ATN) in trained children.
• Stronger relationships were observed between inhibitory control scores and functional connectivity in the right middle frontal gyrus (MFG) in the trained group.

Conclusions:

• Computer-based cognitive training, when integrated into school environments, can effectively enhance children's cognitive and academic abilities.
• The training appears to modulate brain functional connectivity within attentional networks, particularly involving the MFG.
• These findings support the use of school-based cognitive training programs as a viable method for improving cognitive function and academic outcomes.
