以前的发现表明，通感体验可能会对刺激的感觉加工产生影响，而刺激本身并不会触发通感。例如，与非联觉者相比，体验颜色的联觉者表现出对颜色的更强的感知处理。本研究旨在通过对比感觉敏感者的触觉和颜色敏感度来研究增强的知觉处理是否是通感的核心属性，这些联觉者将颜色、触觉或触摸和颜色都作为唤起的感觉。为了进行比较，还评估了非通感对照受试者的表现。通感体验的形式与感觉增强的形式之间存在一定的关系。体验颜色的联觉者对颜色的敏感度增强，体验触觉的联觉者对触觉的敏感度增强。这些发现表明，超敏感的同时知觉系统可能是通感的一种普遍属性，并与通感条件的理论进行了讨论。
Previous findings imply that synaesthetic experience may have consequences for sensory processing of stimuli that do not themselves trigger synaesthesia. For example, synaesthetes who experience colour show enhanced perceptual processing of colour compared to non-synaesthetes. This study aimed to investigate whether enhanced perceptual processing was a core property of synaesthesia by contrasting tactile and colour sensitivity in synaesthetes who experience either colour, touch, or both touch and colour as evoked sensations. For comparison the performance of non-synaesthetic control subjects was also assessed. There was a relationship between the modality of synaesthetic experience and the modality of sensory enhancement. Synaesthetes who experience colour have enhanced colour sensitivity and synaesthetes who experience touch have enhanced tactile sensitivity. These findings suggest the possibility that a hyper-sensitive concurrent perceptual system is a general property of synaesthesia and are discussed in relation to theories of the condition.
