  1. Most subjects described the tone-induced synesthetic colours occurring internally, while a few experienced them externally. Apart from this polarity, one subject described the synesthetic colours occurring in a gaze-centred manner. Furthermore, for many subjects, the spatial locations varied depending on their posture and/or the sound source. Many subjects also reported their synesthetic colours being unaffected by interfering aspects.
