Georgia Institute of Technology researchers have now learned how the Master of Suspense affects audiences’ brains. Their study measured brain activity while people watched clips from Hitchcock and other suspenseful films. During high suspense moments, the brain narrows what people see and focuses their attention on the story. During less suspenseful moments of the film clips, viewers devote more attention to their surroundings.
