AbstractSynaesthesia is a condition in which perceptual or cognitive stimuli (e.g., a written letter) trigger atypical additional percepts (e.g., the colour yellow). Although these cross-modal pairings appear idiosyncratic in that they superficially differ from synaesthete to synaesthete, underlying patterns do exist and these can, in some circumstances, reflect the cross-modal intuitions of nonsynaesthetes (e.g., higher pitch sounds tend to be 'seen' in lighter colours by synaesthetes, and are also paired to lighter colours by nonsynaesthetes in cross-modal matching tasks). We recently showed that grapheme-colour synaesthetes are more sensitive to sound symbolism (i.e., crossmodal sound-meaning correspondences) in natural language compared to nonsynaesthetes (Bankieris & Simner, 2012). Accordingly, we hypothesize that sound symbolism may be a guiding force in synaesthesia, to dictate what types of synaesthetic experiences are triggered by words. We tested this hypothesis by examining the cross-modal mappings of lexical-gustatory synaesthete, JIW, for whom words trigger flavour experiences. We show that certain phonological features (e.g., front vowels) systematically trigger particular categories of taste (e.g., bitter) in his synaesthesia. Some of these associations agree with sound symbolic patterns in natural language.
