最近的数据表明，一些精神病理状况与行为和生理反应可变性的改变有关。病理性担忧，被定义为对潜在威胁的认知表征，与心跳振荡变异性降低（即心率变异性降低；HRV）和反应时间（RTs）索引的注意力缺失有关。临床注意缺陷人群在执行持续注意任务时，RTs振荡在0.05和0.01 Hz左右。我们测试了一个假设，即倾向于担心的人会以一种可预测的振荡模式来焦虑，这种模式通过反复出现的注意力缺失和伴随的HRV振荡来揭示。招募了60名健康的年轻人（50%为女性）：30名超过了宾夕法尼亚州立大学焦虑问卷（PSWQ; High-Worry， HW）的临床临界值；其余30人组成低忧虑组（LW）。在诊断评估后，参与者完成了两个15分钟的持续注意力任务，其间穿插着标准化的焦虑诱导程序。评估RTs、HRV和情绪。频谱分析表明，在焦虑诱导后，与基线和对诱导过程无反应的LW组相比，HW组的RTs振荡在0.01 Hz（周期100 s）左右出现了显著更高且恒定的峰值。生理上，诱导显著降低了高频HRV，这种降低与自我报告的担忧水平有关。结果与默认模式网络（DMN）的振荡性质一致，并进一步证实了认知刚性和自主神经系统不灵活性之间的关联。
Recent data suggests that several psychopathological conditions are associated with alterations in the variability of behavioral and physiological responses. Pathological worry, defined as the cognitive representation of a potential threat, has been associated with reduced variability of heart beat oscillations (i.e., decreased heart rate variability; HRV) and lapses of attention indexed by reaction times (RTs). Clinical populations with attention deficit show RTs oscillation around 0.05 and 0.01 Hz when performing a sustained attention task. We tested the hypothesis that people who are prone to worry do it in a predictable oscillating pattern revealed through recurrent lapses in attention and concomitant oscillating HRV. Sixty healthy young adults (50% women) were recruited: 30 exceeded the clinical cut-off on the Penn State Worry Questionnaire (PSWQ; High-Worry, HW); the remaining 30 constituted the Low-Worry (LW) group. After a diagnostic assessment, participants performed two 15-min sustained attention tasks, interspersed by a standardized worry-induction procedure. RTs, HRV and moods were assessed. The analyses of the frequency spectrum showed that the HW group presents a significant higher and constant peak of RTs oscillation around 0.01 Hz (period 100 s) after the induction of worry, in comparison with their baseline and with the LW group that was not responsive to the induction procedure. Physiologically, the induction significantly reduced high-frequency HRV and such reduction was associated with levels of self-reported worry. Results are coherent with the oscillatory nature of the default mode network (DMN) and further confirm an association between cognitive rigidity and autonomic nervous system inflexibility.
