Cassandra Shivers-Williams

OU CIMMS Post-Doctoral Research Associate

My overarching research interests and experiences are in the psychological processes of decision making. I have worked on various projects examining factors that influence individuals’ decision making in a wide variety of contexts, including decisions made in response to health, terrorist, and natural hazard threats. My dissertation research examined the effects of values, expectations, and mortality reminders on individuals’ choices between available courses of action in the face of potentially deadly natural hazard situations. Other projects I have recently been involved with were focused on elucidating how emergency managers disseminate risk communications during weather emergencies, how these communications influence individuals’ decisions to engage in recommended protective actions, and, more broadly, the social and psychological impacts of severe weather. My post-doctoral research will be aimed at understanding how members of the public process risk information in the face of impending natural hazard threats, and how that information then influences their willingness to take self-protective actions.
