Scientists from Goldsmiths, University of London, have unveiled the emotional triggers behind 'goosebump moments' in a study conducted at Warner Bros. Studio Tour London - The Making of Harry Potter. The research found that these spine-tingling experiences are most likely when multiple intense emotions, particularly joy and nostalgia, converge.

The study, commissioned by Warner Bros., monitored the physiological responses of first-time visitors to the attraction. Using hand sensors to measure Galvanic Skin Response (GSR), researchers observed peaks as high as 99% above baseline during key moments, such as the encounter with the Ukrainian Ironbelly dragon on the Destroyed Gringotts set. Participants reported feelings of immersion, excitement, and awe, with emotional intensity reaching up to 80%.

Professor Jonathan Freeman highlighted the novelty of conducting such research in a real-world setting, contrasting it with traditional lab-based studies. "The Studio Tour offers a unique environment where spectacle and narrative combine to evoke complex emotional responses," he noted.

A supporting survey of 2,000 UK adults revealed that 41% associate excitement with goosebumps, whilst 35% cited surprise, 31% joy, and 21% nostalgia. The findings suggest that early-life memories significantly contribute to these moments, with special family outings and first-time cinema experiences frequently mentioned.

Laura Sinclair-Lazell, Head of Show Experience at the Studio Tour, expressed delight at understanding the physiological impact of the tour. The research underscores the importance of emotional immersion and attention in creating these memorable experiences
