Sub-group networks sorted from fastest team (top left) to slowest team (bottom right). Each team member is represented by a node which size is proportional to its degree. Degree expresses how long a team member was on average in a sub-group with each other team member. Roles are indicated by different colors. Links between nodes represent the time that the corresponding team members were in one sub-group, nodes of team members which were longer in the same sub-group are shown to be closer together. Sub-group networks of faster teams are more heterogeneous, whereas slower teams have more homogeneously connected networks. This indicates that faster teams split more quickly into the task demanded sub-groups and thus were better spatially coordinated.
