Crossing senses with Professor Charles Spence
Seeing senses: Sight, flavour and how expectation reshapes experience

“None of us believe that our senses affect us as much as, in fact, the evidence shows that they do.” Professor Charles Spence

What if your eyes are misleading your tongue?

In this episode of Seeing Senses, experimental psychologist Professor Charles Spence joins Sarah to explore how our senses cross paths more often than we think. From pink yoghurt that tastes sweeter to salty strawberry ice cream, he reveals how the brain uses sight to predict flavour, and how even trained wine tasters can be fooled.

They discuss the dominance of vision in taste perception, the pitfalls of unexpected packaging, and why a pencil and paper sometimes beat brain scans in his lab. It’s a science-rich journey into crossmodal perception, showing how our expectations shape experience across food, design, and daily life.

Listen if you're curious about:

  • How colour influences flavour
  • Why vision overrides taste more often than we realise
  • What crossmodalism really means in everyday perception
  • Why blind tastings and disconfirmation reveal hidden biases
  • How to design better multisensory experiences
  • Why even experts fall for sensory illusions

//

Key themes & takeaways:

  • Visual cues shape flavour perception, often before we taste
  • Crossmodalism explains how the senses work in combination, not isolation
  • Sight dominates—even among expert tasters
  • Colour, context, and packaging set powerful expectations
  • Sensory illusions are common, and often go unnoticed
  • Memory and perception are linked, especially around food
  • Designing for the senses can create more memorable, effective experiences
  • Expectation can override reality, even in flavour
  • Simple tools often reveal more than high-tech equipment
  • The senses influence us more deeply than we admit
