非联觉的人倾向于系统地将某些形状与特定颜色（即圆形红色、三角形黄色、方形蓝色）联系起来。在本研究中，我们研究了这种颜色-形状关联是否会影响错觉连接。两个字母呈现在中央，而两个彩色形状的刺激呈现在外围。参与者被要求报告：（1）字母是否相同，（2）特定形状的颜色，以及（3）颜色选择的置信度。颜色形状刺激与颜色形状关联一致或不一致。结果显示，参与者在不一致的情况下报告了更多的虚幻连接。因此，颜色-形状关联可能先于并随后影响特征绑定，和/或通过自上而下的反馈影响绑定。
Non-synesthetic people tend to systematically associate certain shapes with particular colors (i.e., circle-red, triangle-yellow, square-blue). In the present study, we investigated whether such color-shape associations influence illusory conjunctions. Two letters were centrally presented, while two colored-shape stimuli were presented in the periphery. Participants were asked to report: (1) whether the letters were identical, (2) the color of a specific shape, and (3) the confidence of the color choice. The colored-shape stimuli were either congruent or incongruent with the color-shape associations. Results showed that participants reported more illusory conjunctions in the incongruent condition. Thus, color-shape associations might precede and subsequently affect feature binding, and/or affect binding via top-down feedback.
