    Summary

    This study on process control found operators experienced "cognitive lockup" during system failures, delaying responses. Eye tracking revealed insights into operator information processing beyond traditional performance metrics.

    Area of Science:

    • Human-Computer Interaction
    • Cognitive Psychology
    • Process Control Engineering

    Background:

    • Understanding operator behavior in complex systems is crucial for safety and efficiency.
    • Traditional performance metrics may not fully capture cognitive processes during system disturbances.

    Purpose of the Study:

    • To investigate operator responses to simulated thermal hydraulic system failures.
    • To explore the phenomenon of 'cognitive lockup' and serial fault management.
    • To assess the utility of eye movement tracking in understanding process control.

    Main Methods:

    • Operators managed a simulated thermal hydraulic system (Crossman's waterbath task).
    • Behavioral data (keystroke commands) and eye movements were collected.
    • System disturbances and failures were introduced to assess operator responses.

    Main Results:

    • Evidence of 'cognitive lockup' and a preference for serial fault management was observed.
    • Fixation durations remained stable, but faulty subsystems were examined more frequently.
    • Eye tracking provided deeper insights into information processing during control tasks.

    Conclusions:

    • Eye movement data offers significant added value over traditional measures for understanding operator performance.
    • Cognitive lockup can lead to delayed actions even when operators examine relevant subsystems.
