Research Abstract

In this study, we investigated mechanisms of group decision making in eusocial rodents, the naked mole-rats. Group decision making refers to a process in which two or more individuals select one choice out of several possible ones. This species form complex tunnel systems underground in which different rooms are determined by group members. We investigated how this species decide the room allocation by combining behavioural observation, experiments, and simulation. Our aim was to promote our understanding of group decision making in socially complex mammals.
