The Impact Of Binaural Beats On Creativity
Notes for this study:
||Increased divergent creativity reported in those with low striatal dopamine. Those with high striatal dopamine may actually do worse.
|Number of Subjects
One study, conducted in 24 people, has investigated the effect of binaural beats on divergent (e.g., answering “how many ways can you use a piece of paper?”) and convergent (e.g., answering “what single word could be put in front of ‘market’, ‘star’, and ‘hero’?”) creativity. This experiment exposed participants to alpha or gamma beats with white noise or a constant 340Hz tone for 3 minutes prior and during a creativity task. Additionally, striatal dopamine levels were estimated using “eye-blink rates” (EBRs). Both alpha and gamma beats seemed to improve divergent thinking in people with low EBRs (<20blinks/min), but could actually impair those with higher EBRs. The researchers suggest that those with low EBRs have low dopamine and have more room for improvement, or it could be because dopamine improves neural synchronization which helps people who are lower, but creates more noise for those who are sufficiently high.
