Choice_i,t = β₀ + β₁SCRresiduals_i,t β₂Uncertainty type_i,tChoice ~ SCR residuals Uncertainty Type; where the SCR residuals are taken from the independent risk and ambiguity regressions reported in Table 1 (indexed by subject and trial). Uncertainty type is an indicator variable for risk (0) and ambiguity (1). Regressions are also run separately for risk and ambiguity.
