Professor Charles Spence is the Crossmodal Research Laboratory Head at the Department of Experimental Psychology, Oxford University. He studies how the human brain manages to process and analyze external stimuli to create vibrant multisensory experiences. Charles has published over 500 articles over the last 15 years and has been recognized for his skills and contribution in cognitive science. He is also the author of the book Sensehacking: How to Use the Power of Your Senses for Happier, Healthier Living, where he writes about how everyday objects affect our wellbeing.

Charles joins me today to discuss how the senses affect one another in what are called cross-modal effects, and why sound is getting more attention when it comes to branding and product design. He describes scenarios of how sound affects the way we perceive the taste of our food or our decisions throughout the day. He explains the concept of super-additivity, where adding congruent sensory messages creates a powerful multiplier effect, and shares real-world applications. He reveals how music is being used in healthcare spaces and how it aids physicians and patients. Charles also describes the importance of multisensory congruence in space design, including for our homes.

“Just because you are not aware of sound, doesn’t mean it’s not there, going to your brain and affecting you.”
