Dutch writer Arnon Grunberg writes his new novella with a brain wave tracking cap on. The NYT describes the experiment: “Over the past two weeks, Mr. Grunberg has spent several hours a day writing his novella, while a battery of sensors and cameras tracked his brain waves, heart rate, galvanic skin response (an electrical measure of emotional arousal) and facial expressions. Next fall, when the book is published, some 50 ordinary people in the Netherlands will read it under similarly controlled circumstances, sensors and all. Researchers will then crunch the data in the hope of finding patterns that may help illuminate links between the way art is created and enjoyed, and possibly the nature of creativity itself.”
