“To examine how poetry affects listeners, Wassiliwizky and his team conducted two experiments. For the first, the researchers monitored the heart, face, and skin hair activity of 27 native German speakers as they listened to recordings of self-selected poems that were deemed to be emotionally powerful. The poems were drawn from a wide span of time, covering everything from Shakespearian sonnets to modern German works.
“All of the listeners experienced chills. Eleven exhibited piloerection — also known as goosebumps — where their skin hairs involuntarily stood on end.”
