通感是一种令人着迷的状态，当人们面对普通刺激时，他们会报告非凡的体验。在这里，我们检查了一个经历时间单位的个体（L）（即，一年中的月份和一天中的小时）占据特定的空间位置（一月是中线左侧30度）。Smilek等人（2007）最近研究了这种形式的时空通感，他们证明通感的时空关联是高度一致的，无论意图如何都会发生，并且可以引导空间注意力。我们扩展了这项工作，表明对于联觉者L，她的时空Vantage点的变化取决于时间单位是看到还是听到。例如，当L看到JANUARY这个词时，她报告说在她的左侧经历了一月，但是当她听到“一月”这个词时，她在她的右侧经历了这个月。L的主观报告使用空间线索范式进行验证。月份的名称被集中呈现，然后是左侧或右侧的目标。L是更快地检测目标的有效线索的位置相对于无效线索的位置，无论是视觉提示（一月定向注意向左）和听觉提示（一月定向注意向右）。我们用一天中的几个小时复制了视觉和听觉提示效果的这种差异。我们的研究结果支持以前的研究表明，时空通感可以偏见的视觉空间注意，并进一步表明，对于这种通感，时空协会不同，这取决于他们是否是视觉或听觉诱导。(C)2009 Elsevier Srl.

Synaesthesia is a fascinating condition whereby individuals report extraordinary experiences when presented with ordinary stimuli. Here we examined an individual (L) who experiences time units (i.e., months of the year and hours of the day) as occupying specific spatial locations (January is 30 degrees to the left of midline). This form of time-space synaesthesia has been recently investigated by Smilek et al. (2007) who demonstrated that synaesthetic time-space associations are highly consistent, occur regardless of intention, and can direct spatial attention. We extended this work by showing that for the synaesthete L, her time-space vantage point changes depending on whether the time units are seen or heard. For example, when L sees the word JANUARY, she reports experiencing January on her left side, however when she hears the word "January" she experiences the month on her right side. L's subjective reports were validated using a spatial cueing paradigm. The names of months were centrally presented followed by targets on the left or right. L was faster at detecting targets in validly cued locations relative to invalidly cued locations both for visually presented cues (January orients attention to the left) and for aurally presented cues (January orients attention to the right). We replicated this difference in visual and aural cueing effects using hour of the day. Our findings support previous research showing that time-space synaesthesia can bias visual spatial attention, and further suggest that for this synaesthete, time-space associations differ depending on whether they are visually or aurally induced.
