Individual differences in synaesthesic experiences have recently received much interest, with synaesthetes typically being classified as either projectors (seeing colours projected externally in space) or associators (experiencing colours in their "minds eye"). However, the current standard method of ascertaining these differences through self-reported ratings of statements has been found to be unreliable. Here, we report a test-retest comparison of two sequentially presented questionnaires, asking participants to rate how well the depictions reflect their own experiences. The first questionnaire used standard rating statements, while the second presented the synaesthetic experience in a visual, illustrated format. Results from 12 female synaesthetes highlighted the test-retest consistency with the illustrated questionnaire to be significantly higher than statements alone, suggesting that the visual presentation more approximates and reflects the synaesthetic experience. Through doing so, the illustrated questionnaire is considered to enable an accurate and reliable partition of synaesthetes into projectors and associators.
最近，联觉体验中的个体差异受到了广泛关注，联觉者通常被分为投射者（看到颜色投射到外部空间）或联想者（在“脑海中”体验颜色）。然而，目前通过对陈述进行自我报告评分来确定这些差异的标准方法已被发现不可靠。在此，我们报告了对两份顺序呈现的问卷进行的重测比较，要求参与者对这些描述在多大程度上反映了他们自己的体验进行评分。第一份问卷使用标准评分陈述，而第二份问卷以视觉插图的形式呈现联觉体验。12名女性联觉者的结果表明，带有插图的问卷的重测一致性显著高于仅使用陈述的问卷，这表明视觉呈现更接近并反映了联觉体验。通过这样做，带有插图的问卷被认为能够将联觉者准确可靠地分为投射者和联想者。
