时空联觉者“看到”以空间形式组织的时间单位。虽然对于大多数联觉者来说，这种结构可能是不变的，但有些人看待日历的角度有些灵活。一个被充分研究的联觉者L在几个月的时间里采用了不同的观点。有趣的是，L声称更喜欢她的听觉视角，尽管月份名称在视觉上是颠倒的。为了验证这一点，我们使用了一个空间提示任务，包括视听月线索。这些线索是一致的LS首选的“听觉”的观点（仅视觉和听觉+月倒置）或不一致的（直立视觉和听觉+月直立）。我们的预测是，L将显示增强的线索效应（有效和无效的目标之间的反应时间差异较大）以下的视听一致的线索，因为都引起了“首选”的听觉角度。此外，当面对冲突的线索，我们预测L会选择首选的听觉角度的视觉角度。正如我们所料，L确实表现出增强的线索效应后，视听一致的线索，对应于她的首选听觉角度，但视觉角度占主导地位时，L同时面对两个观点。结果与序列空间通感的具体化假设（Reverleman，2009）有关。
Time-space synaesthetes "see" time units organized in a spatial form. While the structure might be invariant for most synaesthetes, the perspective by which some view their calendar is somewhat flexible. One well-studied synaesthete L adopts different viewpoints for months seen vs. heard. Interestingly, L claims to prefer her auditory perspective, even though the month names are represented visually upside down. To verify this, we used a spatial-cueing task that included audiovisual month cues. These cues were either congruent with Ls preferred "auditory" viewpoint (auditory-only and auditory + month inverted) or incongruent (upright visual-only and auditory + month upright). Our prediction was that L would show enhanced cueing effects (larger response time difference between valid and invalid targets) following the audiovisual congruent cues since both elicit the "preferred" auditory perspective. Also, when faced with conflicting cues, we predicted L would choose the preferred auditory perspective over the visual perspective. As we expected, L did show enhanced cueing effects following the audiovisual congruent cues that corresponded with her preferred auditory perspective, but that the visual perspective dominated when L was faced with both viewpoints simultaneously. The results are discussed with relation to the reification hypothesis of sequence space synaesthesia (Eagleman, 2009).
