虽然人们普遍认为挫折、困惑和焦虑的经历是具体化的现象，但人们对这些过程如何调节可能无意识但持续存在的微妙身体运动知之甚少。在涉及深度学习和努力解决问题的两项研究中，我们通过跟踪身体运动的低水平动态，使用1/f噪声，粉红噪声或“分形缩放”来解决这个问题。我们的研究结果表明，经历认知平衡的个体的身体运动波动具有相关粉红噪声的特征，但当参与者经历诸如焦虑、困惑和沮丧等诊断性认知困扰的状态时，信号会出现白化。我们将我们的发现定位于强调认知和情感的具体本质的理论，以及将情感和认知过程视为与身体密不可分的自组织动力系统（大脑）的紧急产物的观点。
Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or "fractal scaling", during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.
