In 2010, Professor Sébastien Tremblay of Université Laval founded Co-DOT, a cognitive ergonomics research laboratory. The work of researchers and students in the lab focuses on Human Cognition in accordance with three main themes: its Distribution across individuals; its Organization when dealing with high-reliability situations; and Technologies designed to augment its capacity. Co-DOT’s mission is about pursuing innovative research regarding these issues and transferring the resulting methods and knowledge to the field of cognitive ergonomics. Based on a cognitive system engineering approach, our research aims to better understand the cognitive factors involved in dynamic decision making and to establish those conditions that ensure optimal team work performance. This knowledge is used to propose standards for the creation and application of decision support systems, as well as methodological tools for evaluating human performance.
