State dependent valuation: the effect of deprivation on risk preferences.

Furthermore, when separating the reward types, the average fitted risk parameter in the deprived state was higher than in the satiated state for food (Wilcoxon rank test; n = 54, z = −1.96, p = 0.05) and there was a marginally significant effect for money (Wilcoxon rank test; n = 54, z = −1.82, p = 0.069) and a trend in the same direction for water (Wilcoxon rank test; n = 54, z = −1.68, p = 0.092).
