Developments in cognitive neuroscience have led to the emergence of hyperscanning, the simultaneous measurement of brain activity from multiple people. Hyperscanning is useful for investigating social cognition, including joint action, because of its ability to capture neural processes that occur within and between people as they coordinate actions toward a shared goal. Here, we provide a practical guide for researchers considering using hyperscanning to study joint action and seeking to avoid frequently raised concerns from hyperscanning skeptics. We focus specifically on EEG hyperscanning, which is widely available and optimally suited for capturing fine-grained temporal dynamics of action coordination. Our guidelines cover questions that are likely to arise when planning a hyperscanning project, ranging from whether hyperscanning is appropriate for answering one’s research questions to considerations for study design, dependent variable selection, data analysis, and visualization. By following clear guidelines that facilitate careful consideration of the theoretical implications of research design choices and other methodological decisions, joint action researchers can mitigate interpretability issues and maximize the benefits of hyperscanning paradigms.

联合行动研究中脑电图超扫描实用指南：从动机到实施

认知神经科学的发展导致了超级扫描的出现，即同时测量多人的大脑活动。超扫描对于研究社会认知（包括联合行动）非常有用，因为它能够捕获人们在协调行动以实现共同目标时发生的内部和之间的神经过程。在这里，我们为考虑使用超扫描来研究联合行动并寻求避免超扫描怀疑论者经常提出的担忧的研究人员提供了实用指南。我们特别关注脑电图超扫描，它应用广泛，最适合捕获动作协调的细粒度时间动态。我们的指南涵盖了规划超级扫描项目时可能出现的问题，从超级扫描是否适合回答研究问题到研究设计、因变量选择、数据分析和可视化的考虑因素。通过遵循明确的指导方针，促进仔细考虑研究设计选择和其他方法决策的理论含义，联合行动研究人员可以减轻可解释性问题，并最大限度地发挥超扫描范式的好处。
