A behavioural and biological study of risk and ambiguity

Abstract

This thesis focuses on how individuals and groups perceive and behave in the face of risky and ambiguous outcomes. There has been much research on how individuals behave in these situations, but much less investigation into when and why they behave in this way. These questions are addressed from a behavioural, neuro-biological and environmental perspective and answered using individual and group lab-based experiments. The results of these experiments indicate that the amount of information presented, prevailing sentiment and biological factors all influence how we make decisions and the extent to which these decisions are "logical".
