Practitioners with higher cue utilization show lower cognitive load during operational tasks. This suggests cue utilization can identify operators skilled in sustained attention and inform training interventions.

Area of Science:

  • Cognitive Psychology
  • Human Factors Engineering
  • Neuroscience

Background:

  • Simulated studies link cue utilization to cognitive load in process control.
  • Real-world applicability for qualified practitioners remained unclear.

Purpose of the Study:

  • To investigate if cue utilization predicts sustained attention in qualified practitioners during operational tasks.
  • To assess cognitive load using physiological and behavioral measures.

Main Methods:

  • Classified Australian distribution network service provider (DNSP) operators by cue utilization levels.
  • Measured cerebral oxygenation and eye behavior during regular work tasks.
  • Compared physiological workload indicators between higher and lower cue utilization groups.

Main Results:

  • No significant differences in eye behavior metrics were found between groups.
  • Operators with higher cue utilization exhibited reduced prefrontal cortex oxygenation increases.
  • This indicates lower cognitive load during regular operational activities.

Conclusions:

  • Higher cue utilization is associated with lower cognitive load in operational tasks.
  • Cue utilization assessment can identify operators with better sustained attention.
  • Findings support cue-based training for improving operator performance.
