Show moreEven after thousands of years of experience in treating patients with TBI, decisions regarding the optimal treatment strategy remain difficult for both healthcare workers as policy makers. The first part of this thesis investigated the challenges of the treatment decision-making process in patients with (severe) TBI by focussing on three factors considered to be important in this process: patient outcome, in-hospital healthcare consumption, and in-hospital costs. The second part investigated the procedural difficulties in TBI research efficiency by focussing on the process of institutional review board approval and the use of informed consent procedures in patients with TBI with an inability to provide informed consent. Finally, we elaborate on the role of patient outcome and in-hospital costs in the acute treatment decision-making process in patients with severe TBI and make suggestions to optimize future research initiatives.

Show moreThis thesis consists of three empirical chapters that investigate elements of human social behavior, adherence to and violations of social norms, and the computational and neurological underpinnings thereof. I focus on three behavioral paradigms in particular – the attacker-defender contest, the trust game, and the ultimatum game – which model asymmetrical conflicts, generosity and reciprocity, and norms of fairness, respectively. Ultimately, each chapter acts as a building block contributing a different perspective to the study of human sociality. Using economic games, computational models based on the principle of utility, and model-based neuroimaging, my research contributes to the scientific endeavor working to crack the “elaborate and secret code that is written nowhere, known by none, and understood by all” (Sapir, 1927, p.137) Show less
