Numerous empirical studies identified fractal noise in human behavior. According to the theory of Self Organized Criticality, long memory 1/f scaling is a signature of stable and adaptive complex dynamical systems. This article discusses the following aspects of fractality research: (a) generation of fractal noise in simulation studies; (b) quality of some popular estimators of fractal parameters; (c) measurement artifacts in cognitive performances. 36 time series obtained in response tasks experiments under three different task conditions serve as empirical basis.
众多实证研究在人类行为中发现了分形噪声。根据自组织临界性理论，长记忆1/f标度是稳定且自适应的复杂动力系统的一个特征。本文讨论了分形研究的以下几个方面：（a）模拟研究中分数噪声的产生；（b）一些常用分形参数估计器的质量；（c）认知表现中的测量伪迹。在三种不同任务条件下的反应任务实验中获得的36个时间序列作为实证依据。
