Abstract

In this work, I integrate three research projects focused on exploring the neurocognitive basis of voluntary decision making in humans. The thesis consists of two main parts. First part (Chapters 1 to 3) focuses on reviewing the theoretical context of my later work. Chapter 1 introduces the main concepts of interest and scientific questions that motivate my work. Chapter 2 reviews the scientific contributions, such as previous findings, theoretical conceptualizations, and experimental frameworks on which my empirical work is built upon. Chapter 3 discusses the methodological philosophy my work follows. Each theoretical chapter starts with a brief introduction, giving the reader a glimpse of the topics to come, followed by sections discussing these points in more depth. Second part (Chapters 4 to 7) describes the empirical research. Chapter 4 reports the findings of an fMRI experiment on the brain correlates of voluntary choices between equal options in a perceptual discrimination task (later referred to as Project 1 ). Chapter 5 describes an EEG study on the mechanisms of breaking decisional deadlocks, when faced with equally valuable options in a probabilistic choice task (later referred to as Project 2 ). Chapter 6 reviews a set of 5 behavioural studies on how a confirmatory bias induced by voluntary decisions affects future choices and evaluations (later referred to as Project 3 ). Chapter 7 summarizes the three projects and discusses their contributions and limitations
