Executive Function and Transfer Effect Training in Children: A Behavioral and Event-Related Potential Pilot Study.

Area of Science:

• Cognitive Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Executive functions, including updating and inhibition, are crucial for cognitive development in children.
• Targeted training can enhance these executive functions, but the optimal training approach remains under investigation.

Purpose of the Study:

• To investigate the effectiveness of single versus combined executive function training on updating and inhibition in children.
• To examine the transfer effects of this training on untrained cognitive tasks and fluid intelligence.
• To explore the neural correlates of executive function training using event-related potentials (ERPs).

Main Methods:

• Two experiments were conducted involving children undergoing single (2-back) or combined (2-back and flanker) executive function training.
• Control groups received active training without specific executive function targets.
• EEG data, including event-related potentials (ERPs), were collected to assess neural changes.

Main Results:

• Combined training demonstrated greater near-transfer effects than single training, particularly for tasks sharing cognitive components with the training.
• Training led to significant changes in ERPs, including reduced N2 amplitude and increased P300 amplitude, correlating with improved behavioral performance.
• No significant transfer was observed for fluid intelligence or task shifting.

Conclusions:

• Combined executive function training is more effective than single training for improving specific cognitive skills in children.
• The degree of transfer is influenced by the overlap in cognitive components between training and transfer tasks.
• ERP changes provide neural evidence supporting the behavioral improvements seen after executive function training.
