SUMMARY:Vigilance Decrements Attributed to Bias Shifts, Attentional Lapses
 , and Guess Rates but Not Sensitivity: A Replication Experiment of McCarle
 y and Yamani (2021)
DESCRIPTION:Kayla Hankey (Old Dominion University), Jason McCarley (Oregon
  State University), and Yusuke Yamani (Old Dominion University)\n\nThe abi
 lity to monitor rare signals is critical in many high-stake tasks, yet, th
 e human performance literature suggests that detection rate for such signa
 ls decline sharply over time on task—sometimes within as little as half an
  hour-- a phenomenon known as vigilance decrement. Some work using signal 
 detection theory has suggested that the vigilance decrement reflects a los
 s of sensitivity, but other findings have attributed the decrement solely 
 to criterion changes and mental lapses. The current experiment replicates 
 earlier studies using analysis of psychometric function to distinguish amo
 ng these possibilities. The results confirm that conservative bias shifts 
 and attentional lapses are the primary mechanisms of the decrement, and gi
 ve no evidence for sensitivity losses. Designers of automated technologies
  for monitoring tasks such as surveillance, air traffic control, and secur
 ity screening may find these results useful in developing strategies to mi
 tigate vigilance failures in real-world settings.\n\nTrack: Perception and
