我们最近提出，系统性的时间再生不足是由对早期反应的一般判断偏差引起的，而不是反映了对时间间隔的真正误解。在这里，我们测试了这种偏见是否可以解释与时间判断的不确定性。我们应用经颅磁刺激（TMS）抑制右侧后顶叶皮层（PPC）的神经元过程，并测试其对时间辨别和再现任务的影响。结果表明，PPC抑制后，辨别时间判断的确定性增加。他们认为，右PPC对时间知觉起抑制作用，可能是通过介导时间刺激和其他量之间的多感觉整合。重要的是，这种增加的判断确定性对暂时性生殖不足的程度没有影响。我们的结论是，系统的时间再生不足是不是由时间判断的不确定性。
We recently proposed that systematic underreproduction of time is caused by a general judgment bias towards earlier responses, instead of reflecting a genuine misperception of temporal intervals. Here we tested whether this bias can be explained by the uncertainty associated with temporal judgments. We applied transcranial magnetic stimulation (TMS) to inhibit neuronal processes in the right posterior parietal cortex (PPC) and tested its effects on time discrimination and reproduction tasks. The results show increased certainty for discriminative time judgments after PPC inhibition. They suggest that the right PPC plays an inhibitory role for time perception, possibly by mediating the multisensory integration between temporal stimuli and other quantities. Importantly, this increased judgment certainty had no influence on the degree of temporal underreproduction. We conclude that the systematic underreproduction of time is not caused by uncertainty for temporal judgments.
