Figure 2. Model of choice integrating the effects of disappointment and risk in addition to the maximization of expected values.

Figure 2

Negative coefficients reflect minimization of disappointment or risk. Model A integrates the effects of anticipating disappointment (d) in addition to the maximization of expected values (EV). MS patients did not minimize d. Model B integrates the effects of risk in addition to the maximization of expected values (e). Healthy controls were risk neutral while MS patients were risk averse.
