A BIT of The Hidden Sense

In this BIT, Cretien van Campen explores synesthesia--when two or more senses cooperate in perception--by examining what happens people perceive numbers in colors and numbers in spatial forms. Cretien describes how these perceptions affect synesthetes’ mental arithmetic and what this tell us about visual thinking in general.

Synesthesia in Art and Science

What is does it mean to hear music in colors, to taste voices, to see each letter of the alphabet as a different color? These uncommon sensory experiences are examples of synesthesia, when two or more senses cooperate in perception. Once dismissed as imagination or delusion, metaphor or drug-induced hallucination, the experience of synesthesia has now been documented by scans of synesthetes' brains that show "crosstalk" between areas of the brain that do not normally communicate.
