Cognitive control is defined by a set of neural processes that allow us to interact with our complex environment in a goal-directed manner. Humans regularly challenge these control processes when attempting to simultaneously accomplish multiple goals (multitasking), generating interference as the result of fundamental information processing limitations. It(More)
Large-scale online communities need to manage the tension between critical mass and information overload. Slashdot is a news and discussion site that has used comment rating to allow massive participation while providing a mechanism for users to filter content. By default, comments with low ratings are hidden. Of users who changed the defaults, more than(More)
Many virtual communities involve ongoing discussions, with large numbers of users and established, if implicit rules for participation. As new users enter communities like this, both they and existing members benefit when new users learn the standards for participation. Slashdot is a news and discussion site that has developed a system of distributed(More)
Under what circumstances might a group member be better off as a long-distance participant rather than collocated? We ran a set of experiments to study how partially-distributed groups collaborate when skill sets are unequally distributed. Partially distributed groups are those where some collaborators work together in the same space (collocated) and some(More)
In studies of virtual teams, it is difficult to determine pure effects of geographic isolation and uneven communication technology. We developed a multi-agent computer model in NetLogo to complement laboratory-based organizational simulations [3]. In the lab, favoritism among collocated team members (collocators) appeared to increase their performance.(More)
Significant prior research has shown that facilitation is a critical part of GSS transition. This study examines an under-researched aspect of facilitation—its contributions to self-sustained GSS use among group members. Integrating insights from Adaptive Structuration Theory, experimental economics, and the Collaboration Engineering literature, we(More)
