Previous studies showed that hypnotized individuals underestimate temporal intervals in the range of several seconds to tens of minutes. However, no previous work has investigated whether duration perception is equally disorderly when shorter time intervals are probed. In this study, duration perception of a hypnotic virtuoso was tested using repeated standard temporal generalization and duration estimation tasks. When compared to the baseline state, hypnosis affected perception of intervals spread around 600 ms in the temporal generalization task but did not alter perception of slightly longer intervals spread around 1000 ms. Furthermore, generalization of temporal intervals was more orderly under hypnosis than in the baseline state. In contrast, the hypnotic virtuoso showed a typical time underestimation effect when perception of longer supra-second intervals was tested in the duration estimation task, replicating results of the previous hypnosis studies.
先前的研究表明，被催眠的个体往往低估几秒钟到几十分钟范围内的时间间隔。然而，之前的研究尚未探究在探测更短的时间间隔时，时长感知是否同样无序。在这项研究中，通过重复使用标准的时间泛化和时长估计任务，测试了一位催眠大师的时长感知。与基线状态相比，催眠在时间泛化任务中影响了大约 600 毫秒的间隔感知，但并未改变大约 1000 毫秒的稍长间隔的感知。此外，在催眠状态下，时间间隔的泛化比基线状态更加有序。相比之下，当在时长估计任务中测试较长的超过两秒的间隔感知时，这位催眠大师表现出典型的时间低估效应，这与之前的催眠研究结果一致。
