Sustained Attention and Vigilance

  • Sustained attention involves maintaining attention for more than a few seconds and is distinct from shifting or dividing attention.
  • Multiple Object Tracking (MOT) is a paradigm for studying sustained attention, with a tracking limit of approximately 4 items.
  • Event-related potentials N2pc and CDA are associated with MOT, with N2pc occurring when selecting targets among distractors and CDA occurring when maintaining items in visual working memory.
  • The Visual Index Theory suggests that MOT is limited by the number of slots and automatic tracking of multiple objects in parallel, with the speed of motion affecting the number of objects that can be tracked.
  • Vigilant attention involves sustaining attention for more than 10 seconds on an intellectually unchallenging, monotonous task, and is challenging compared to cognitively demanding tasks.
  • Monitoring for rare targets in visual search or multiple object monitoring can lead to missed targets due to perception, search, and decision/response factors.
  • Railway network operators use the Multiple Object Monitoring task (MOM) to intervene swiftly and accurately in the rare event of computer errors in controlling train pathways.
  • MOM results show robust replicable vigilance decrements and dissociable measures of sustained attention from vigilance effects, with neural patterns predicting behavioral errors.
  • Vigilance decrements may occur due to resource depletion from continuous allocation of attention in a monotonous task and mind-wandering resulting from boredom.
  • Real-world searches for rare targets are effortful, and understanding factors affecting quitting thresholds may be beneficial for theoretical and practical reasons.
  • Theoretical models of search struggle with "target absent" trials, and studying MOM provides insights into sustained/vigilant attention theories.
  • Next steps involve exploring if real-time feedback can prevent errors and testing theories of sustained/vigilant attention to understand why vigilance decrements occur.
