The purpose of this research is to examine whether outcome controls of group work (i.e. time pressure and reward) trigger psychological factors (i.e. distraction, motivation, and trust) and affect problem-solving virtual teams? ability to share information and develop high quality solutions. Results of a laboratory experiment on GSS-based virtual teams indicate that teams exhibited higher motivation and trust under time pressure while only trust, in turn, has a positive relationship with information sharing. However, reward control has no significant impact on any psychological factors. We also find evidence supporting that total information shared is positively associated with problem-solving outcomes in terms of the solution quality.
