The Autonomous Sensory Meridian Response (ASMR) is a tingling sensation across the scalp that occur in response to specific triggering audio and visual stimuli, connected with the Default Mode Network. Our study (N = 76) aimed to test the neurophysiology of ASMR by examining pupil diameter and brain activity. Assuming the idiosyncratic nature of ASMR, we expected results detecting opposite physiological outcomes considering pupil diameter and brain activation. We used a battery of self-reports to investigate psychological dimensions; for the physiological measures, we used two instruments: PupilCore and NeuroSky MindWave Mobile 2. The results showed an augmented pupillary diameter during the ASMR video, regardless of the perception of tingles. On the other hand, the arousal level during the ASMR video was lower than the other conditions. The difference between the two neurophysiological measures appeared as peculiar and can be considered as the promoting phenomenon for ASMR psychological outcomes.
自主感觉经络反应(ASMR)是一种头皮刺痛的感觉,是对特定触发音频和视觉刺激的反应,与默认模式网络有关。我们的研究(N=76)旨在通过检查瞳孔直径和大脑活动来测试 ASMR 的神经生理学。考虑到 ASMR 的特质,我们预计会检测到瞳孔直径和大脑激活的相反生理结果。我们使用一系列的自我报告来调查心理维度;对于生理测量,我们使用了两种仪器:PupilCore 和 NeuroSky MindWave Mobile 2。结果表明,在观看 ASMR 视频时,瞳孔直径会增大,而不管是否感觉到刺痛。另一方面,在观看 ASMR 视频时的唤醒水平低于其他条件。这两种神经生理测量之间的差异似乎很特殊,可以被认为是促进 ASMR 心理结果的现象。
