Thirty-nine student groups participated in a laboratory experiment conducted to study the effects of leadership style (transactional vs. transformational), anonymity (identified vs. anonymous interaction), and rewards (individual vs. group) on creativity-relevant group processes and outcomes in two decision-making tasks supported by an electronic meeting system (EMS). Evidence for social loafing was observed, i.e., anonymity led to lower participation and cooperation in the group rewards condition relative to the individual rewards condition. Further analysis revealed that social loafing was confined to the transactional leadership condition. Corresponding to the social loafing effect, anonymity led to lower group efficacy and satisfaction with the task and higher originality of solutions in the group rewards condition relative to the individual rewards condition. Transactional leadership was associated with greater group efficacy and solution originality than transformational leadership. Anonymity moderated the effects of leadership on group efficacy and satisfaction with the task; transactional leadership was associated with higher group efficacy and satisfaction with the task in the identified condition only.
