Abstract：
Grapheme-color synesthesia is expected to provide a clue to solving the \"binding problem\" of visual features. Synesthetic research uses non-synesthetes as a control group and shows that synesthetes perform better with synesthetic color congruency, while non-synesthetes\' performances do not. However, non-synesthetes also have certain grapheme-color associations. Therefore, this study examined whether non-synesthetes\' grapheme-color associations improve their performance in a visual search task. The results indicated that non-synesthetes were significantly faster at detecting congruent targets with their grapheme-color associations, such as red for \"A,\" blue for \"B,\" and yellow for \"C.\" However, the effect was not found in relation to numerical characters. This study has implications for future neuroscience and consciousness research regarding grapheme-color synesthesia.
摘要：
石墨色联觉有望为解决视觉特征的“绑定问题”提供线索。联觉研究使用非联觉者作为对照组，并表明联觉者在联觉色彩一致性方面表现更好，而非联觉者的表演不会。然而,非联觉者也具有一定的字素-颜色关联。因此,这项研究检查了非同调的字素-颜色关联是否可以改善其在视觉搜索任务中的表现。结果表明，非语法在检测具有字素-颜色关联的全等目标时明显更快，如红色代表\“A，“蓝色代表”B，\"和黄色代表\"C\"然而,没有发现与数字字符相关的效果。这项研究对未来有关字素-颜色联觉的神经科学和意识研究具有意义。
