Control variables. We included team size and team composition as control variables
in our analyses (van Knippenberg and Schippers, 2007). Team size was controlled for
its potential to impact a team’s ability to establish and build on TMMs, and for its
potential to impact on more conflict situations. Team size was measured through the
number of team members. For the control variable team composition, we transformed
the categorical variable into two dummy variables, using student teams as a baseline
since they represent more teams in the simulation.
