人体通过自主神经系统以多种方式对神经认知应激做出反应。心率、唾液皮质醇和皮肤电导水平的增加通常伴随着高水平的压力。压力也可以有不同的形式，包括情感的、认知的和动机的。虽然缺乏对压力的准确定义，但一个相关的问题是量化神经系统中表现出的心理压力状态。状态空间模型已经被应用于根据生理信号测量和行为实验期间收集的数据来估计未观察到的神经状态(例如，学习、意识)。在本文中，我们将应力与皮肤电导信号中出现相位驱动脉冲的概率联系起来。我们将状态空间建模应用到提取的二元测量中，以连续跟踪认知和情绪压力以及放松过程中的压力水平。结果表明，通过可穿戴设备跟踪压力是一种很有前途的方法。
The human body responds to neurocognitive stress in multiple ways through its autonomic nervous system. Increases in heart rate, salivary cortisol and skin conductance level are often observed accompanying high levels of stress. Stress can also take on different forms including emotional, cognitive and motivational. While a precise definition for stress is lacking, a pertinent issue is to quantify the state of psychological stress manifested in the nervous system. State-space models have previously been applied to estimate an unobserved neural state (e.g. learning, consciousness) from physiological signal measurements and data collected during behavioral experiments. In this paper, we relate stress to the probability that a phasic driver impulse occurs in skin conductance signals. We apply state-space modeling to extracted binary measures to continuously track a stress level across episodes of cognitive and emotional stress as well as relaxation. Results demonstrate a promising approach for tracking stress through wearable devices.
