Grapheme-color Synesthesia – a Case Study Report

Synaesthesia had been described as early as in 1883 by Francis Galton, but until recently it was perceived merely as a subjective phenomenon impossible to study using objective methods. Th e development of neuroscience and the consciousness studies created the possibility of scientific study of this phenomenon. At present many types of synesthesia are known, and there are many theories trying to explain its mechanisms. Understanding the answer to the question of the nature of synesthesia may be faciliated by a standarized method of Synesthesia Batter Test developed by David Eagleman and his colleagues, which allows to explore synesthetic experience and compare reliable data from diff erent laboratories. Th is paper presents this method and a case of EW, experiencing the most common type of synesthesia, grapheme-color. Th is means, that when EW sees letters or numbers, she has an experience of color.
