SUMMARY:Assessing the Impact of Differential Sources of Fatigue and Sleep 
 Deprivation on Risk-Taking Behavior
DESCRIPTION:Tiash Rana Mukherjee (Texas A&M University), Ranjana Mehta (Un
 iversity of Wisconsin - Madison), and Steven Riechman (Texas A&M Universit
 y)\n\nMost occupations require workers to do tasks with extreme mental and
  physical demands. Over time, these sustained demands without adequate res
 t and recovery lead to occupational fatigue, negatively impacting their sa
 fety, productivity, and health. They are more likely to engage in risky be
 havior, which is further associated with increased errors and unwanted acc
 idents. Despite these issues, there is a lack of literature comprehensivel
 y evaluating the differential effects of the different sources of fatigue,
  namely mental, physical, and sleep deprivation, on risk-taking behaviors.
  Therefore, this study aims to address this gap by investigating the relat
 ionship between different sources of fatigue and risk-taking behavior by u
 sing the Balloon Analogue Risk Task (BART). BART simulates real-world risk
 y task demands where riskiness is awarded to a certain level; however, exc
 eeding that level has negative consequences. A within-subjects experiment 
 with 75 participants (30 females) was conducted. Each participant complete
 d BART sessions on different days before and after a two-hour physically o
 r mentally fatiguing task, or 30 hours of extended wakefulness.  Results r
 evealed that the effects of fatigue on risk-taking behaviors are both sour
 ce- and sex-dependent. Results from this research can aid in developing ta
 rgeted interventions and policies to mitigate unwanted fatigue-related ris
 ky behaviors at work.\n\nTrack: Cognitive Engineering & Decision Making\n\
