The Prevalence and Spectrum of Synesthesia

This chapter discusses the prevalence of synesthesia in society and explores the idea that synesthesia may exist on a spectrum, with some people experiencing it more intensely than others. The chapter presents the Buba-Kiki effect as evidence of cross-connecting different sensory domains, where people associate visual shapes with spoken sounds. It further explores various examples, such as associating musical notes with spatial positions and describing voices and colors using textures, suggesting that low-level synesthesia may be present in the general population.
