我们评估了Doppel的镇静效果，Doppel是一种可穿戴设备，可以在手腕上提供类似心跳的触觉刺激。我们测试了在预期公开演讲期间，使用多普勒是否会对生理唤醒和状态焦虑的主观报告产生镇静作用，这是一项经验证的实验任务，已知会引起焦虑。两组受试者采用单盲设计进行测试。两组人在准备公开演讲时都把这个装置戴在手腕上，并被告知这个装置是用来测量血压的。仅对于一组，该设备被打开并发出缓慢的心跳般的振动。与对照组相比，在多普勒活跃条件下的参与者显示皮肤电导反应相对于基线的增加较低，并且报告了较低的焦虑水平。因此，存在，而不是它的缺席，慢节奏，这在本研究中被例示为一个辅助缓慢的心跳通过多普勒传递，有一个显着的镇静作用的生理唤醒和主观经验，在社会压力的情况下。这一发现进行了讨论，过去的研究反应和夹带节奏，以及它们对唤醒和情绪的影响。
We assessed the calming effect of doppel, a wearable device that delivers heartbeat-like tactile stimulation on the wrist. We tested whether the use of doppel would have a calming effect on physiological arousal and subjective reports of state anxiety during the anticipation of public speech, a validated experimental task that is known to induce anxiety. Two groups of participants were tested in a single-blind design. Both groups wore the device on their wrist during the anticipation of public speech, and were given the cover story that the device was measuring blood pressure. For only one group, the device was turned on and delivered a slow heartbeat-like vibration. Participants in the doppel active condition displayed lower increases in skin conductance responses relative to baseline and reported lower anxiety levels compared to the control group. Therefore, the presence, as opposed to its absence, of a slow rhythm, which in the present study was instantiated as an auxiliary slow heartbeat delivered through doppel, had a significant calming effect on physiological arousal and subjective experience during a socially stressful situation. This finding is discussed in relation to past research on responses and entrainment to rhythms, and their effects on arousal and mood.
