Research output: Types of ThesisDoctoral ThesisInternal


This thesis explores how social context influences the neurobiological processes underlying decision-making. To this end, this research takes an interdisciplinary approach, combining methods and insights from Psychology, Marketing, Economics, and Neuroscience. In particular, behavioural responses are collected, and used in combination with both functional magnetic resonance imaging (fMRI) techniques and pharmacological interventions examining the role of the hormone oxytocin in decision-making. The first part of this thesis is concerned with the effects of social influence on decision-making, or in other words, how human decisions are influenced by the behaviour and beliefs of other people. Specifically, this part examines the influence of both celebrity endorsements and peer groups on the neural processes underlying decision-making. The second part of this thesis investigates the influence of social norms on decision-making. This section examines the neural processes involved in cooperation and the role of oxytocin in social norm enforcement.
