From the coordination of individual brains to effective collective decision-making

1 Ph.D/Postdoctoral Position

Research objectives: The overarching goal of the project is to identify determinants of successes and failures of collective decisions. To gain a more comprehensive understanding of these outcomes and the underlying processes, we will integrate perspectives from game theory, social psychology, and social neuroscience. Work Package 1 builds upon established paradigms in studying decision-making and strategic interactions to identify key variables related to task environments and group composition. Work Package 2 develops new measures allowing the online assessment of coordination among group members. Specifically, we will test the hypothesis that effective group coordination can be assessed by electroencephalography (EEG) measures of inter-subject brain synchronisation. The findings from the two work packages will provide the foundation for experimental hypothesis testing. In the next phase of research, we plan to study selected groups (i.e. 10–15 individuals) that are exposed to selected tasks, and will use portable EEG to provide online measures of synchronisation among members of the group. We envision that this approach enables us to predict the success or failure of collective decisions based on a mechanistic understanding of group decision-making. (Advisor: Harald Schupp)
