Creative flow as optimized processing: Evidence from brain oscillations during jazz improvisations by expert and...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Music Cognition

Background:

• The flow experience is a state of optimal performance and engagement.
• Previous research offers competing theories on the neural underpinnings of flow, particularly regarding default-mode network (DMN) activity.
• Understanding flow's neural basis is crucial for optimizing creative performance.

Purpose of the Study:

• To test competing hypotheses about the neural correlates of the flow experience during jazz improvisation.
• To investigate the role of domain-specific versus domain-general neural processing in flow.
• To examine how experience modulates neural activity during creative flow.

Main Methods:

• Electroencephalography (EEG) was used to record brain activity in jazz guitarists during improvisation.
• The Core Flow State Scale measured participants' subjective experience of flow.
• Neuroimaging analysis (SPM12) reconstructed neural sources associated with flow states.

Main Results:

• High-flow states were associated with transient hypofrontality across all musicians.
• Experienced musicians in high-flow states showed reduced activity in posterior DMN nodes.
• Less experienced musicians did not show significant DMN or fronto-parietal control network (FPCN) modulation related to flow.

Conclusions:

• Creative flow appears to be a state of optimized domain-specific processing, characterized by reduced cognitive control.
• Extensive practice may facilitate domain-specific neural adaptations supporting flow.
• Findings support the hypothesis that flow involves reduced interference from task-negative networks, particularly in experts.
