联觉是一种罕见的情况，在这种情况下，刺激的一个属性(例如形状)会触发第二种感觉(例如颜色)，而不是通常与第一种感觉相关联。关于通感的研究主要集中在确认通感经验的真实性上，但很少有人研究通感与更广泛的知觉差异之间的联系程度。在这里报道的这项研究中，我们通过比较感觉为颜色的联会受试者和非联觉受试者的这些能力来检验联觉是否与颜色和运动加工的差异有关。我们发现，对颜色的通感与易化的颜色敏感度有关，但降低了运动敏感度。这些发现与典型成年人的通感以及颜色和运动加工之间的相互作用的神经认知机制有关。
Synesthesia is a rare condition in which one property of a stimulus (e.g., shape) triggers a secondary percept (e.g., color) not typically associated with the first. Work on synesthesia has predominantly focused on confirming the authenticity of synesthetic experience, but much less research has been conducted to examine the extent to which synesthesia is linked to broader perceptual differences. In the research reported here, we examined whether synesthesia is associated with differences in color and motion processing by comparing these abilities in synesthetes who experience color as their evoked sensation with nonsynesthetic participants. We show that synesthesia for color is linked to facilitated color sensitivity but decreased motion sensitivity. These findings are discussed in relation to the neurocognitive mechanisms of synesthesia and interactions between color and motion processing in typical adults.
