患有序列空间联觉(SSS)的人报告了与数字、天和月(以及其他)相对应的稳定的视觉空间形式。这种类型的通感让科学家们感兴趣了130多年,但由于缺乏一种公认的评估工具,阻碍了对这一现象的研究。本研究建立在先前测试的基础上,通过测量空间位置的一致性来区分控制和联会。我们首次记录了这种测试的敏感性和特异性,并建议了一个诊断分界点,用于根据同一物品的不同放置尝试所限定的区域来区分不同组。本文的在线版本(doi:10.3758/s13428-0150656-2)包含补充材料,授权用户可以使用。
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.
