  • Mechanisms of Vigilance Loss in Sensory and Cognitive Tasks

    Creator:
    Gyles, Shannon P.
    Abstract:
    When observers monitor for infrequent signals for extended durations, they generally experience a decline in detections over time. This decline is termed the vigilance decrement. Current theories of vigilance attribute the decrement to three potential mechanisms: conservative shifts in response bias, losses of sensitivity, and an increased rate of attentional...

  • Automation-Aided Collaborative Strategies in Signal Detection Tasks

    Creator:
    Duncan-Reid, Jackson
    Abstract:
    Automated systems have become increasingly important to human decision making and task performance in a wide variety of complex fields and situations. Decision aids, a specific form of automation, assist human operators in making complex decisions under conditions of uncertainty, such as air traffic control or combat identification. When humans...

  • Metacognition, Numeracy, and Automation-aided Decision-making

    Creator:
    Gyles, Shannon P.
    Abstract:
    Automated decision aids can improve human decision-making but the benefits are often compromised by inefficient use. The current experiment examined whether metacognition—the ability to assess self-performance—and numeracy—the ability to understand and work with numbers—predict the efficiency of automation use in a signal detection task. Two-hundred twenty-one participants classified random dot...

  • Collaborative Metacognition and Decision Making in a Signal Detection Task

    Creator:
    Duncan-Reid, Jackson
    Abstract:
    When decision makers work collaboratively, their combined performance can exceed the performance of even the best group member working alone. However, despite the potential for performance gains when working in a group, collaborating individuals often show poor coordination and losses of motivation, and are generally inefficient at combining their resources...
