Mean subjective value expressed as averaged indifference points. All data are expressed as proportions. In case of time-probability trade-off the means can be interpreted in terms of probability, and in f(t) and f(p) conditions as a proportion of immediate/certain subjective value to larger later/certain reward. The panels refer to (standard deviations are presented in order gain PLN 200, gain PLN 5000, loss PLN 200, loss PLN 5000): (A) p(t)—probability-time trade-off (SDs respectively: 0.245, 0.205, 0.301, 0.254); (B) f(t)—delay discounting (SDs respectively: 0.236, 0.250, 0.289, 0.288); (C) f(p)—probability discounting conditions (SDs respectively: 0.181, 0.196, 0.225, 0.253).
