Divergent thinking training enhanced frontal alpha synchronization in participants. This suggests training improves top-down inhibition, crucial for focused cognitive processes during creative tasks.

Area of Science:

  • Neuroscience
  • Cognitive Psychology

Background:

  • The electroencephalogram (EEG) alpha band is associated with cognitive processes.
  • Frontal alpha activity has been linked to top-down inhibitory control.

Purpose of the Study:

  • To investigate the effect of divergent thinking training on frontal alpha activity.
  • To explore the role of frontal alpha synchronization in cognitive control during creative tasks.

Main Methods:

  • Participants (n=30) underwent pre- and post-tests involving divergent thinking tasks.
  • A training group received 2 weeks of divergent thinking exercises.
  • Event-related EEG alpha band activity was measured.

Main Results:

  • The training group showed significantly higher task-related synchronization of frontal alpha activity compared to the control group.

  • Increased alpha power during the activation interval indicated enhanced frontal alpha synchronization.

    • Conclusions:

    • Divergent thinking training can enhance frontal alpha synchronization.
    • Frontal alpha synchronization may reflect a top-down inhibitory mechanism supporting focused cognitive processing during demanding tasks.
