We present the results of the analysis of the effect of a bodily-contact communication medium on the brain activity of the individuals during verbal communication. Our results suggest that the communicated content that is mediated through such a device induces a significant effect on electroencephalogram (EEG) time series of human subjects. Precisely, we find a significant reduction of overall power of the EEG signals of the individuals. This observation that is supported by the analysis of the permutation entropy (PE) of the EEG time series of brain activity of the participants suggests the positive effect of such a medium on the stress relief and the induced sense of relaxation. Additionally, multiscale entropy (MSE) analysis of our data implies that such a medium increases the level of complexity that is exhibited by EEG time series of our participants, thereby suggesting their sustained sense of involvement in their course of communication. These findings that are in accord with the results reported by cognitive neuroscience research suggests that the use of such a medium can be beneficial as a complementary step in treatment of developmental disorders, attentiveness of schoolchildren and early child development, as well as scenarios where intimate physical interaction over distance is desirable (e.g., distance-parenting).
我们展示了对一种身体接触式交流媒介在言语交流过程中对个体大脑活动影响的分析结果。我们的结果表明，通过这种设备介导的交流内容对人类受试者的脑电图（EEG）时间序列产生了显著影响。具体而言，我们发现个体EEG信号的总体功率显著降低。参与者大脑活动的EEG时间序列的排列熵（PE）分析支持了这一观察结果，表明这种媒介对缓解压力和诱导放松感具有积极作用。此外，我们数据的多尺度熵（MSE）分析表明，这种媒介增加了参与者EEG时间序列所表现出的复杂程度，从而表明他们在交流过程中持续的参与感。这些与认知神经科学研究报告结果一致的发现表明，使用这种媒介作为治疗发育障碍、学童注意力和幼儿早期发展的补充步骤，以及在需要远距离亲密身体互动的场景（如远程育儿）中可能是有益的。
