This study explores interoceptive attentiveness (IA) influence on autonomic reactivity related to pain and self-regulation during situations evoking physiological mirroring for pain. 20 participants observed face/hand, painful/non-painful stimuli in an individual versus social condition while the autonomic response was measured [Electrodermal activity, Pulse Volume Amplitude (PVA), and Heart Rate (HR)] was measured. The sample was divided into experimental (EXP) subjects, required to focus on their interoceptive correlates while observing the stimuli, and the control (CNT) group. HR inter-beat interval (IBI), and HR Variability (HRV) were calculated. Results showed high accuracy to painful and non-painful stimuli recognition. Regarding autonomic indices, higher PVA values were detected for hand painful versus non-painful stimuli, whereas for the EXP group a significant activation of IBI was found for face painful vs non-painful stimuli. In the context of observation of pain in others, PVA and IBI could be respectively markers of mirroring mechanisms and autonomic self-regulation mediated by IA.
本研究探讨了在引发疼痛生理镜像的情境中，内感受性注意力（IA）对与疼痛和自我调节相关的自主反应性的影响。20名参与者在个体和社会条件下观察面部/手部、疼痛/非疼痛刺激，同时测量自主反应[皮肤电活动、脉搏容积振幅（PVA）和心率（HR）]。样本被分为实验（EXP）组和对照组（CNT），实验组成员在观察刺激时需要专注于自身的内感受性关联。计算了心率的心动间期（IBI）和心率变异性（HRV）。结果显示对疼痛和非疼痛刺激的识别准确率很高。关于自主指标，手部疼痛刺激与非疼痛刺激相比，检测到更高的PVA值，而对于实验组，面部疼痛刺激与非疼痛刺激相比，发现IBI有显著激活。在观察他人疼痛的情境中，PVA和IBI可能分别是由IA介导的镜像机制和自主自我调节的标志物。
