Abstract: Teamwork is a topic of growing interest and is ubiquitous in a variety of fields in today’s reality. Public safety is no exception to the rule. Events such as the Rambla attacks in Barcelona or the World Trade Center in New York have shown that video surveillance is a major asset in the role of responders and that it is critical to further understand human surveillance performance. In relation to teamwork in control rooms, operational procedures and the division of labor are not harmonized. Using a laboratory-simulated video surveillance task within the Cognitive Solution to Security Surveillance (CSSS) microworld, the present study first aimed to verify whether, when compared to individual work, teamwork has an impact on performance. Secondly, the present study aimed to compare the impact of two strategies of division of tasks on performance: Task allocation was either based on the spatial dimension, each operator being in charge of a specific set of cameras, or goal-oriented, each operator receiving specific research objectives beforehand. Results showed that for a given supervisory task, teams detected more incidents than participants who completed the task individually, however, goal-oriented teams reported the lowest mental workload. Overall, the use of more sophisticated strategies than the spatial division of screens, such as goal-oriented strategies, should be considered in control rooms in order to distribute the workload in a more structured and ergonomic way.
