  • 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...

  • 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...
