Abstract :
Technology supported collaboration and communication between individuals entails complex social and psychological situations. An understanding of social and psychological aspects of collaboration is essential to creating productive work environments. The use of collaboration and communication systems is framed by the psychological and social factors concerning the users and their work environment. It is important to understand these factors to successfully facilitate the sustained use of these technologies. Further, knowledge of the psycho-social aspects of technology-supported collaboration and communication also assists in detecting, avoiding, and effectively resolving issues that may arise from using such technologies. This minitrack provides a venue for studying issues related to the dynamic interplay between people, their environment, and the collaboration technologies they use to create collaborative value. In its inaugural year, this minitrack received 13 papers, 8 of which were accepted. These submissions cover a variety of topics ranging from trust to stereotypes and social spheres to self-regulation and personality. The first paper by Choi, "Motivated Information Processing in Groups: A Design of a Computational Model" examines human motivations and biases in group information-processing. The author develops a computational model based on the hidden profile model, the motivated information-processing model, and the information asymmetries model that informs the design of agents for modeling group processes. In the second paper, "Revisiting Social Influence in the Ubiquitous Computing Era", Zeal, Smith, and Scheepers report on a study of mobile technology users in which they examine various social influences on these individuals. They isolate four different variants of social influence and integrate these as categories of social influence into an analytical framework for future research. The third paper by Semnani-Azad, Sycara, Adair, and Lewis, "Stereotyp- and Perception Change in Inter-cultural Negotiation" describes a study on how cognitive schemas such as stereotypes influence our perception, beliefs and behavior toward members of a social group. In an experiment where North American observers viewed intercultural negotiation videos, the authors found in-group bias across all observers, change in perceptions across different negotiation stages, and variation of initial stereotypes as a function of negotiation outcome. In the paper "Every post you make, every pic you take, I\´ll be watching you: Behind social spheres on Facebook", Marder, Joinson, and Shankar present a study on social anxiety from fear of having communications be perceived negatively. Using self-discrepancy theory as a lens to view social norms and social spheres, the authors find strong support for the assumptions underlying social anxiety and for the argument that social network sites can cause anxiety and tension in social relations. The paper by Zhang and Turel, "A Member - Virtual Team Fit Theory: Group Conscientiousness Effects on Performance", studies the effect of virtual team personality composition on performance. The authors empirically test a model with data from 61 teams. Their findings suggest that the elevation level of team conscientiousness improves performance, while higher within-team diversity in conscientiousness lowers performance. The sixth paper by Lockwood and Massey, "Communicator Trust across Media: A Comparison of Audio Conferencing, Video Conferencing, and a 3D Virtual Environment" investigate trust towards a communicator through audio conferencing, video conferencing, and virtual worlds using media determinant theories and uncertainty reduction theory. Based on repeated measures data on individual perceptions the authors found that effects appear to change over time.
