Three experiments were conducted with 10 grapheme-colour synaesthetes and 10 matched controls to investigate (a) whether awareness of the inducer grapheme is necessary for synaesthetic colour induction and (b) whether grapheme-colour synaesthesia may be bidirectional in the sense that not only do graphemes induce colours, but that colours influence the processing of graphemes. Using attentional blink and Stroop paradigms with digit targets, we found that some synaesthetes did report "seeing" synaesthetic colours even when they were not able to report the inducing digit. Moreover, congruency effects (effects of matching the colour of digit presentation with the synaesthetic colour associated with that digit) suggested that grapheme-colour synaesthesia can be bidirectional, at least for some synaesthetes.
我们对10位字形-颜色联觉者和10位匹配的对照组人员进行了三项实验，以研究：（a）诱发字形的意识对于联觉颜色诱发是否必要；（b）字形-颜色联觉是否可能具有双向性，即不仅字形能诱发颜色，而且颜色会影响字形的加工。通过使用带有数字目标的注意瞬脱和斯特鲁普范式，我们发现一些联觉者即使无法报告诱发数字，也确实报告“看到”了联觉颜色。此外，一致性效应（将数字呈现的颜色与该数字相关的联觉颜色相匹配的效应）表明，至少对一些联觉者来说，字形-颜色联觉可以是双向的。
