当一个人试图从记忆中产生一个给定的空间或时间间隔时，不可避免地会有一些与估计有关的错误。这种误差的时间过程是通过一系列实验来测量的，在这些实验中，受试者反复尝试重复给定的目标间隔。在空间和时间重复中发现误差序列以1/f噪声波动。1/f噪声在各种各样的物理系统中都遇到过，并且在理论上被认为是复杂性的特征特征。
When a person attempts to produce from memory a given spatial or temporal interval, there is inevitably some error associated with the estimate. The time course of this error was measured in a series of experiments where subjects repeatedly attempted to replicate given target intervals. Sequences of the errors in both spatial and temporal replications were found to fluctuate as 1/f noises. 1/f noise is encountered in a wide variety of physical systems and is theorized to be a characteristic signature of complexity.
