| 摘要: | 人類是社會性生物，其中在社會互動中協作互動是種不可或缺的一部分，在以往研究人類之間的協作互動時一般採取行為上的研究，然而在協作互動背後的神經活動卻相對地少被研究，因此本研究旨在深入探討雙人協作任務中參與者的腦部活動是否呈現出關聯性及探討實驗中的神經活動。本研究使用腦電圖（Electroencephalogram，EEG）記錄了兩位參與者在虛擬實境（Virtual Reality，VR）中共同執行協作任務期間的腦部活動，事後分析中首先將事件間隔以1秒當作閥值切割不同協作下的行為，最後評估了參與者之間腦部活動的同步性、參與者不同身分的腦部活動的個別差異性及不同協作下的差異性。研究結果顯示，在雙人協作任務中，參與者的腦部活動呈現出一定程度的同步性，我們發現在 α 頻帶中的額葉、中央及頂葉中發現顯著性，在 β_1 頻帶中的中央及頂葉中發現顯著性，在 β_3 頻帶中大部分的右半腦感興趣的腦區（Regions Of Interest，ROI）中存在差異性，而在 β_2 中大部分的ROI存在差異性；而在雙人協作任務中參與者不同身分的腦部活動呈現出不一樣的活動差異，我們先將受試者對分成領導者及跟隨者並發現領導者在大部分ROI中有差異性，而跟隨者中發現不同頻帶中存在差異性。在 β_1 /α 中除了右額葉外中存在差異性；在 β_2 /α 中的t < 1秒時除了F4外所有ROI都有差異性，而在t >1秒時只有C3、P3、P4有差異性；在 β_3 /α 中只有Fz及頂葉區有差異。總體而言，本研究提供了初步證據，認為雙人協作任務中的腦部同步可能與任務執行有關。這為進一步探索協作與腦部活動之間的關係提供了基礎，同時也突顯了需要更深入研究以解釋這種複雜關係的必要性。;Human beings are social animals, among whom collaborative interaction in social settings is an indispensable part. Previously, research on human collaborative interactions typically focused on behavioral studies. However, the neural activities underlying these collaborative interactions have been relatively understudied. Therefore, this research aims to delve into whether there is a correlation in brain activity among participants in a dyadic collaborative task and to explore the neural activities during the experiment. In this study, we used Electroencephalogram (EEG) to record the brain activities of two participants engaged in a collaborative task within a Virtual Reality (VR) environment. In the post-analysis, we first segmented the behaviors under different collaborations by using a 1 second interval as a threshold, and then assessed the synchrony of brain activity between participants, the individual differences in brain activity of participants with different roles, and the variability under different collaborations. The results showed that, in the dyadic collaborative tasks, the participants′ brain activities exhibited a certain degree of synchrony. We found significant synchrony in the α band in the frontal, central, and parietal lobes, in the 〖 β〗_1 band in the central and parietal lobes, and variability in most regions of interest (ROI) in the right hemisphere in the〖 β〗_3 band, and in most ROIs in the 〖 β〗_2 band. Moreover, the brain activities of participants with different roles in the dyadic collaborative tasks showed different patterns of activity. Dividing the subjects into leaders and followers, we found differences in most ROIs in leaders, while in followers, differences were found across different bands. In the β_1/α band, except for the right frontal lobe, differences were found; in the β_2/α band, differences were found in all ROIs except F4 when t < 1 second, and only in C3, P3, P4 when t > 1 second; in the 〖 β〗_3/α band, only Fz and the parietal region showed differences. Overall, this study provides preliminary evidence that brain synchrony in dyadic collaborative tasks may be related to task performance. This lays the foundation for further exploration of the relationship between collaboration and brain activity, while also highlighting the need for more in-depth research to explain this complex relationship |
