Developments in Neuroeconomics have motivated researchers to explore human cognition and behavior at the cerebral-neural level, and the rise of hyperscanning technology has allowed exploring the human social brain in a more ecologically efficient way. In recent years, experimental studies on hyperscanning of economic behavior have contributed substantial evidence. This paper reviews the literature on inter-brain synchronization and sorts out experimental studies of inter-brain synchronization in different economic behaviors. Finally, this paper draws a conclusion of the research in this area and puts forward an outlook.
