“Emotion of Colors: Synesthetic Cross-Modal Key Modulation” by Cai, Asai and Nagata

Synesthesia is a neurological condition in which stimulation of one sensory or cognitive pathway includes automatic and involuntary responses in a second sensory or cognitive pathway. People who report such experiences are known as “synesthetes”. A subset of synesthetes, sound-color synesthetes “see” colors and simple animated shapes in association with music and other sounds. We can find a color-sound synesthetes out of two to three thousands. It has been suggested that “..every infant is synesthetic, although most gradually grow out of it” p 12 (Stein and Meredith 1993) and the synesthetes possess these cross-modal connections even they grown up. We show scientifically how these synesthetic cross-modal mapping are used in animations and movies.
