Abstract

Respiratory sinus arrhythmia (RSA), an index of the parasympathetic nervous system activity, has been considered indicative of stress response and emotion regulation. However, the relationship between RSA and anxiety remains inconclusive, partly because previous research has primarily focused on static RSA levels. In this nonclinical sample (N = 75, M_age = 20.89 ± 1.72 SD, 48 males), we used a damped oscillator model to characterize RSA dynamics across 30-s epochs while participants completed the Trier social stress test. Results showed that RSA constantly oscillated during the three periods of TSST (namely Rest, Stress, and Recovery). Importantly, slower RSA oscillation in the Stress period was related to elevated state anxiety, whereas in the Recovery period, it was related to higher trait anxiety. These findings demonstrated the dynamic nature of RSA during the whole course of stress response. Slower RSA oscillation may indicate inflexible and tardy physiological regulation which may give rise to anxiety issues.

在应激反应和调节过程中，焦虑与较慢的 RSA 振荡有关。

呼吸窦性心律失常（RSA）是副交感神经系统活动的一个指标，一直被认为是应激反应和情绪调节的指标。然而，RSA 与焦虑之间的关系仍无定论，部分原因是以往的研究主要关注静态 RSA 水平。在这个非临床样本中（样本数：75，年龄：20.89 ± 1.72 SD，48 位男性），我们使用阻尼振荡器模型来描述参与者在完成特里尔社会压力测试时 RSA 在 30 秒时间内的动态变化。结果表明，在 TSST 的三个阶段（即休息、压力和恢复），RSA 不断发生振荡。重要的是，应激期的 RSA 振荡较慢与状态焦虑升高有关，而恢复期的 RSA 振荡较慢与特质焦虑升高有关。这些发现表明了 RSA 在整个应激反应过程中的动态性质。较慢的 RSA 振荡可能表明生理调节缺乏灵活性和滞后性，从而引发焦虑问题。

期刊介绍： Founded in 1964, Psychophysiology is the most established journal in the world specifically dedicated to the dissemination of psychophysiological science. The journal continues to play a key role in advancing human neuroscience in its many forms and methodologies (including central and peripheral measures), covering research on the interrelationships between the physiological and psychological aspects of brain and behavior. Typically, studies published in Psychophysiology include psychological independent variables and noninvasive physiological dependent variables (hemodynamic, optical, and electromagnetic brain imaging and/or peripheral measures such as respiratory sinus arrhythmia, electromyography, pupillography, and many others). The majority of studies published in the journal involve human participants, but work using animal models of such phenomena is occasionally published. Psychophysiology welcomes submissions on new theoretical, empirical, and methodological advances in: cognitive, affective, clinical and social neuroscience, psychopathology and psychiatry, health science and behavioral medicine, and biomedical engineering. The journal publishes theoretical papers, evaluative reviews of literature, empirical papers, and methodological papers, with submissions welcome from scientists in any fields mentioned above.
