JS was a grapheme-color synesthete in whom numerals and letters of the alphabet consistently evoked colors. In the first set of experiments we showed that the color - in a consistent and reliable manner - was most pronounced in the left visual field and in central vision. In the second experiment we devised a novel test for eidetic imagery and showed that his self-report of enhanced imagery could be verified experimentally. The implications of these findings for the level at which synesthesia occurs, the 'enhanced cross-activation' model, and the mechanisms of visual memory are discussed.
JS是一名 grapheme - color 联觉者,在他身上,数字和字母总会持续唤起颜色。在第一组实验中,我们发现,颜色以一种一致且可靠的方式,在左视野和中央视觉中表现得最为明显。在第二个实验中,我们设计了一种针对遗觉象的新颖测试,并表明他关于增强意象的自我报告可以通过实验得到验证。我们还讨论了这些发现对于联觉发生层面、“增强交叉激活”模型以及视觉记忆机制的意义。
