People with sequence-space synesthesia (SSS) report stable visuo-spatial forms corresponding to numbers, days, and months (amongst others). This type of synesthesia has intrigued scientists for over 130 years but the lack of an agreed upon tool for assessing it has held back research on this phenomenon. The present study builds on previous tests by measuring the consistency of spatial locations that is known to discriminate controls from synesthetes. We document, for the first time, the sensitivity and specificity of such a test and suggest a diagnostic cut-off point for discriminating between the groups based on the area bounded by different placement attempts with the same item.
患有序列空间联觉（SSS）的人报告称，存在与数字、日期和月份（以及其他事物）相对应的稳定视觉空间形式。这种联觉类型已经吸引科学家们长达130多年，但缺乏一种公认的评估工具阻碍了对这一现象的研究。本研究在先前测试的基础上，测量了已知能区分对照组和联觉者的空间位置一致性。我们首次记录了这种测试的敏感性和特异性，并基于同一项目不同放置尝试所界定的区域，提出了区分两组的诊断临界点。
