Reduced occipital alpha power marks a movement induced state change that facilitates creative thinking

Area of Science:

• Cognitive Neuroscience
• Neurophysiology
• Psychology

Background:

• Movement, particularly walking, is known to enhance creativity and divergent thinking.
• Walking has been associated with reduced occipital alpha activity, a neural correlate.
• The impact of movement restriction on creativity and its neural underpinnings remains less understood.

Purpose of the Study:

• To investigate the effect of movement restriction on occipital alpha power.
• To determine if occipital alpha power serves as a neural marker for creativity under varying movement conditions.
• To explore the relationship between movement, alpha activity, and divergent thinking.

Main Methods:

• Utilized mobile electroencephalography (EEG) to record brain activity in 23 subjects.
• Subjects performed Guilford's alternate uses test under conditions of free and restricted movement.
• Analyzed relative occipital alpha power and alpha lateralization in relation to creativity scores.

Main Results:

• Relative occipital alpha power was significantly higher during movement restriction, irrespective of the task.
• Increased occipital alpha power showed a negative correlation with creativity scores.
• Alpha lateralization was modulated during task-related thinking (sitting) and positively correlated with creativity, independent of alpha power.

Conclusions:

• Movement restriction, such as sitting and screen fixation, elevates occipital alpha power.
• Elevated occipital alpha power is associated with reduced creativity and divergent thinking.
• Ongoing alpha power and alpha lateralization represent distinct neural processes influencing cognitive states and creativity.
