    Neurocomputational Modeling of the Dual-Process Theory of Decision Making and Its Implication for Public Policy Making

    , M.Sc. Thesis Sharif University of Technology Keramati, Mohammad Mahdi (Author) ; Ghaninejad, Moussa (Supervisor)
    Supported by a rich literature in psychology and neuroscience, the dual-process theory of decision making assumes that individuals’ decisions are made through arbitration between habitual and goal-directed processes within their minds. Whereas the goal-directed system makes decisions after deliberating all positive and negative consequences of each feasible choice, the habitual system make choices based on the habits formed in previous experiences. Although the decisions of the goal-directed system are always more optimal that those of the habitual system, but due to that fact that the goal-directed system is slow, effortful and time-consuming, it is sometimes more efficient to make...

    Studying Impediments Social Learning in Economic Policymaking Community of Iran

    , M.Sc. Thesis Sharif University of Technology Ahmadpour Samani, Narjes (Author) ; Mashayekhi, Ali Naghi (Supervisor)
    Social learning approach in economic policymaking is introduced against conflict-based approach in the similar context. Helco, 1973 first studied the effects of such a learning in economic policymaking and said ”men collectively wondering what to do… Governments not only ‘power’… they also puzzle.” The important point in studying policymaking through social learning approach is paradigm shifts in peoples’ mental models. In this approach, policies are not only the result of conflict between different interests but also are the output of a learning process. In this research we first assume that social learning has not occurred in policymaking community and that individual learning has...
