Professor Charles Spence of Oxford University is a leader in Senseploration - the investigation of how our senses mingle and interconnect. His research led him to the conclusion our senses don't operate independently at all. They are intimately, synesthetically connected and cross-referential.
In his research, he explores:
Awareness of Sensory Dominance: When one sense dominates the others
Maximimising the Superadditive: When senses work together to enhance experience
Minimizing the Subadditive: When senses contradict one another
Through his observation he's made fascinating discoveries about our sensory experiences.
