Neural processes engaged in decision-making remain unclear. A decomposition of these processes might help us to understand the involved mechanisms. Indeed, first we need to assign what we will call a ‘subjective value’ to each option – i.e. the quantification of how much we like each of these options. Then, we need to compare those values to finally being able to select one of them. Assigning a value seems to be the function of an interesting brain network which overlaps the reward circuitry identified in animal studies – and which is called the Brain Valuation System (BVS). In the first study of this PhD thesis, we investigated and compared three behavioral ways to have an access to these ‘subjective values’. We found that subjective value...
