Sense of smell is closely linked with memory, and recent research suggests odour-evoked memories are stronger than any memory triggered by music.
A study found that, when compared to music-evoked nostalgia, odours elicited more than twice as many nostalgic reveries.
With this in mind, Google are opening up the Curiousity Room in Selfridges. Dubbed a ‘playground for inquisitive minds’, the venue has four areas of exploration: Animal Atelier, Scent Spectrum, Google Greenhouse, and Micro Kitchen.
The Scent Spectrum is a five-minute workshop in which emotion, memory and science are fused and explained.
