What Makes Us Decide to Trust or Cooperate with Others

What are the psychological and neural mechanisms behind decision-making related to trust, reciprocity, cooperation and fairness in social interactive scenarios? How our expectations of the world shape our responses to social situations and how social norms can have a large impact on our decisions? One of the aims of this research is to develop formal computational, neurally-inspired, models of social preferences. The principles studied are already informing public policy.
