Talk kindly contributed by Álex Sospedra-Orellano in SEMF's 2024 Interdisciplinary Summer School: https://semf.org.es/school2024 TALK ABSTRACT I will review my experience and knowledge in decision making experiments, theories and models, in humans, in contemporary neuroscience. In our daily life, we constantly decide between two or more options after gathering information about them (what’s each articles’ price?, to which point can I trust this person?...). Many studies have modelled decision making in a simplified way; e.g., assuming we accumulate evidence piece by piece in a progressive, continuous way. However, everyday decisions are constantly filled with noisy evidence, and interruptions that force us to keep gathered evidence in our memory. This is compounded by varying levels of arousal, urgency to decide, and personality traits such as impulsivity. For the last decades, several mathematical models have been developed to begin approximating this complexity. Many of them, and the most applied ones, such as diffusion or attractor models, have been borrowed from physics. I will give a superficial, but I hope insightful, review on these topics and the present-day challenges we face.
