Abstract
In an online experiment, groups of 2, 3, 4, or 5 persons have to solve a complex task collectively while interacting in a video chat. The performance of the group determines the monetary payoff of its members. We first investigate how group size affects group performance. We also explore how group members' personal characteristics impact group performance. Moreover, after the group task we ask subjects to state which fellow group members were instrumental for group performance ("leaders"). Finally, we then investigate how leaders' personal characteristics correlate with them being perceived as leaders as well as with group success.

Primary Outcomes

Primary Outcomes (end points)
1) Number of complex tasks solved by groups as well as behavioral patterns in the process of solving tasks

2) subjects' individual assessments of their personal characteristics (cognitive skills, social intelligence, overconfidence)

3) subjects' individual assessment which group member was most instrumental for group performance

4) communication patterns within groups (using microphone log data)
