ABSTRACT Space, numbers and time share similar processing mechanisms mediated by parietal cortex. In parallel to the spatial representation of numbers along a horizontal line, temporal information is mapped on a horizontal axis with short intervals (and the past) represented to the left of long intervals (and the future). Little is known about the representation of time in the presence of visuo-spatial deficits. We here report two experiments on the comparative judgment of time. Experiment 1 required patients with left-sided neglect to indicate which of two consecutively presented silent intervals was longer. Their judgments were better if the first interval was longer and they judged the first interval longer on trials in which the two intervals were equally long. These results were not present in right-hemispheric damaged patients without neglect and healthy controls. They are in line with a previously reported finding in a single patient with neglect, but not readily compatible with findings of neglect patients’ comparative length judgments. In Experiment 2, healthy participants’ performance on an identical task improved for trials with a first-longer interval after caloric vestibular stimulation (CVS) of the right ear with warm water.

改变的时间判断突出了时间和空间感知的共同机制

摘要 空间、数字和时间共享由顶叶皮层介导的类似处理机制。与数字沿水平线的空间表示平行，时间信息映射在水平轴上，短间隔（和过去）表示在长间隔（和未来）的左侧。在存在视觉空间缺陷的情况下，对时间的表示知之甚少。我们在这里报告两个关于时间比较判断的实验。实验 1 要求左侧忽视的患者指出两个连续呈现的沉默间隔中哪一个更长。如果第一个间隔更长，他们的判断会更好，并且在两个间隔相同的试验中，他们对第一个间隔的判断更长。这些结果在没有忽视和健康对照的右半球受损患者中不存在。它们与先前报告的单个忽视患者的发现一致，但与忽视患者的比较长度判断的发现并不容易一致。在实验 2 中，在用温水对右耳进行热量前庭刺激 (CVS) 后，在第一个较长间​​隔的试验中，健康参与者在相同任务上的表现有所提高。
