我们描述了人类行为组织的本质，特别是休息和活动期如何在日常生活中交织在一起。活动期持续时间与体力活动计数连续高于预定义的阈值，当重新调整与个人的手段，遵循一个普遍的拉伸指数（γ型）累积分布的特征时间，无论是在健康个体和重度抑郁症患者。另一方面，两组低于阈值的静息期持续时间在20年内服从无标度幂律累积分布，患者的标度指数显着降低。因此，我们发现了支配人类行为组织的普遍分布规律，其中一个参数在抑郁症中发生了变化。
We describe the nature of human behavioral organization, specifically how resting and active periods are interwoven throughout daily life. Active period durations with physical activity count successively above a predefined threshold, when rescaled with individual means, follow a universal stretched exponential (gamma-type) cumulative distribution with characteristic time, both in healthy individuals and in patients with major depressive disorder. On the other hand, resting period durations below the threshold for both groups obey a scale-free power-law cumulative distribution over two decades, with significantly lower scaling exponents in the patients. We thus find universal distribution laws governing human behavioral organization, with a parameter altered in depression.
