A computational and empirical investigation of prioritization during multiple approach and avoidance goal pursuit

This thesis examines people's prioritization decisions when pursuing multiple approach or avoidance goals. I develop and validate a formal model of multiple-goal pursuit that predicts prioritization based on factors such as the combination of approach and avoidance goals being pursued and environmental uncertainty. I then introduce a normative model of prioritization, which I use to demonstrate that people prioritize in a risk-averse manner when pursuing approach goals and in a risk-seeking manner when pursuing avoidance goals. This thesis provides a link between decision-making and motivation literatures that will ultimately enhance our understanding of multiple-goal pursuit.
