Analysis of Work Tasks from a Cognitive Ergonomics Perspective: Concepts, Models, and Methods | Rutgers University 

February 8, 2019 | Presented By: Katia M. Costa-Black, PhD

Cognitive ergonomics is a subfield of cognitive science especially concerned with the human task-oriented activity in terms of the perceptual, information-processing and psychomotor aspects of work. General models of cognitive task-oriented activity have been developed to account for the complexity of human behaviors produced in work situations, to explain erroneous action, and to conceptualize human-computer interaction. This webinar will present and discuss some of these models and how they have helped in improving the design of technologies, organizational environment and learning environments, as well as in decreasing human error. In addition to the major models and concepts utilized in the field of cognitive ergonomics, several methods based on user-centered design research will be described. These methods aim to collect and integrate data about the user needs and the requirements in the design of systems and organizations for a more successful transformation of the workplace and use of human-sensitive technology. They are very useful, especially today with the rapid growth of complex technological environments and the widespread introduction of information technologies to automate work processes.

Learning Objectives

At the completion of this activity, the learner will be able to:

  • Recognize the main cognitive ergonomics concepts, models, and principles that are relevant to explain the
    complexity of human behaviors produced in various work situations, to explain erroneous action, and to
    conceptualize human-computer interaction.

  • Identify the main methods of evaluation of cognitive aspects of human-technology interfaces to reduce
    human error, optimize mental workload, and enhance health, comfort, safety, effectiveness, and efficiency of
    man-machine systems.
