Dance experience detectable in spectators’ brain activity

University of Helsinki researchers measured the brain activity of people watching a live dance performance in a real-world setting. They invited spectators with extensive experience of either dance or music as well as novices with no particular background in either of these areas.

The spectators’ brain activity was measured using EEG while they watched the live dance duet Un último recuerdo, a piece created by the Spanish Iron Skulls Co that combines contemporary dance and breakdance. The findings are published in the European Journal of Neuroscience.

The results showed that dance experience is detectable in spectators’ brain activity during a dance performance. The experienced dancers watching the performance displayed stronger synchronization than the novices at the low theta frequency.

Experience of dance affects brain functions associated with the visualization of movement in the mind, the simultaneous integration of several sensory stimuli (listening to music and watching dance) and social interaction.

When musicians watched the live dance performance, they had stronger synchrony in the delta band, which is even lower than theta. This may be associated with the musicians’ trained ability to observe rhythmic bodily movements.

Watching dance in a real-world environment is unique for our brain

The effect of watching a dance performance on brain activity has previously been studied by having subjects watch a video recording on their own in a brain research laboratory.

The present study was conducted in a real-world performance environment and shows that watching a live dance performance in a full venue activates the brain more extensively than the above setting.

“As our interaction increasingly moves to online platforms and the virtual world, it’s important to know that real-world interaction is unique—for our body and brain,” says Hanna Poikonen, the lead author of the study.

The results also emphasize the effect of a background in creative movement on the spectator experience.

“If we have practiced our bodily skills, we may better understand the body language of others, which makes social interaction smoother,” Poikonen notes.
