The article reports the results of experiments on human ability to estimate time intervals separately or in groups of two intervals as elements of a three-interval array presented by two light signals separated by a dark interval. The first light interval is shown to be systematically overestimated compared with the second one. Moreover, the subjects usually ascribe a constant value to the dark interval. The double interval (light + dark or dark + light) proves to be underestimated compared with the case when estimation of the same intervals was required without estimation of a third interval. The additional task changes the estimations of the subjects. It may be claimed that the complexity of the problem is connected with definite changes in the average estimations of the subjects.
本文报道了关于人类估计时间间隔能力的实验结果。实验中，两个光信号由一个暗间隔隔开，形成一个三间隔阵列，让人类分别或以两个间隔为一组来估计时间间隔。结果表明，与第二个光间隔相比，第一个光间隔被系统性地高估了。此外，受试者通常会给暗间隔赋予一个恒定值。与在不需要估计第三个间隔的情况下估计相同间隔相比，双间隔（光 + 暗或暗 + 光）被证明是被低估的。额外的任务改变了受试者的估计。可以说，问题的复杂性与受试者平均估计的特定变化有关。
