Calculating in Colors

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.
