1 尽管通常情况下人们在睡眠中不会有对时间的回顾性感知,但似乎在梦里也存在时间知觉(对时间持续的感知)。威廉·德门特(William Dement)用两项研究来证明睡梦中的时间与真实的时间是相似的。因为当人们做梦时,他们的眼睛会在眼皮下非常快速地运动着,德门特能够通过观察睡眠者的快速眼动来监测他们的睡眠并记录他们做梦的时长。在记录了这些数据后,德门特会叫醒睡眠者并让他们写下对最后一个梦的描述。他提出的假设是,与那些较短的梦相比,长时间的梦需要更多地词汇来描述。当对每个梦的报告中所包含的单词数与这个梦所持续的分钟数进行比较时,他发现梦越长,做梦者用来描述它的单词越多。在一个关联实验中,德门特叫醒那些正在做梦的人,询问他们感觉做的最后一个梦持续了多长时间。做梦者对于他们的梦持续了较长时间还是较短时间的感知,其正确率是83%。通过这些实验,德门特得出了睡梦中的时间与清醒状态下的时间几乎是相同的这一结论。在清醒梦中,时间感知似乎也是相同的。可是话又说回来,我们这里所测量的、时间在实际的流逝中所产生的时间感,与我们熟悉的、在入睡和觉醒之间所缺席的那种回顾性时间感是不同的。Dement, W.C.‘History of sleep medicine’.Neurologic Clinics ,23,945-65,v(2005).Bolz, B.‘How time passes in dreams.(2009).http://indianapublicme-dia.org/amomentofscience/time-passes-dreams/.Erlacher, D.et al.‘Time for actions in lucid dreams:effects of task modality, length and complexity’.Frontiers in Psychology ,4,1013(2013).

13 在墨西哥神经生物学研究所的雨果·麦钱特(Hugo Merchant),德博拉·哈灵顿(Deborah Harrington)以及沃伦·梅克(Warren Meck)已经通过猴子的单细胞记录研究识别出时间知觉所涉及的复杂的神经网络,并且强调一个关键的神经回路与皮层——丘脑——基底神经节相关联。他们认为这种带有分布式网络的“时间中枢”可以解释间隔调整(interval tuning)的抽象特征,以及时间幻觉和内部时间感,并且这种建立在大脑核心时间机制中的互相连接,目的是为了提供一种保护性的冗余,以此来对抗损伤、疾病或衰老。Merchant, H.,Harrington, D.L.&Meck, W.H.‘Neural basis of the perception and estimation of time’.Annual Review of Neuroscience ,36,313-36(2013).

21 一种答案是发生了某种低水平的适应:例如,对闪烁刺激的适应会导致个体对随后出现的刺激时长的估计发生扭曲,但这一现象只在刺激呈现于较小的局部空间中时才会发生。由于这一效应如此具有局限性,这意味着在更基础、更早期的视觉区域中存在某些定时的神经元机制。由于这种效果范围极小,因此暗示出,在更为基本、更为早期的视觉区域中,存在着某些用于计时的神经机制。而另一个完全不同的想法是,在大脑处理时间度量的另一个极端上,持续的时间是神经元所消耗的净能量数的一个指标。而这些都是需要加以鉴别的物理的、客观的事件……但我们应该从哪里开始,又通过什么方法进行呢?Johnston, A.,Arnold, D.H.&Nishida, S.‘Spatially localized distortions of event time’.Current Biology ,16,472-9(2006).Pariyadath, V.&Eagleman, D.‘The effect of predictability on subjective duration’.PLoS One ,2,e1264(2007).
