Article from ‘The Psychologist’, vol. 28, no. 2, February 2015
In its simplest form Synaesthesia is best described as a “union of the senses” whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together. Some synaesthetes experience colour when they hear sounds or read words. Others experience tastes, smells, shapes or touches in almost any combination. I have ‘grapheme synaesthesia’ which means I experience colour when I think of letters, words, numbers, the musical keys, chords, the notes on the piano keyboard and music in general.
In this interesting article from The Psychologist, Jack Dutton meets people with the condition and the researchers who study them to reveal the very surprising world of synaethesia, including its impact on memory and how it may even be taught.
