Figure 6. — Comparing delayed reward and punishment discounting. a, Rats shifted preference toward the immediate reward as the delay increased, indicative of delay discounting. b, Individual differences in delay discounting, with each curve representing an individual rat. c, AUC for discounting of delayed rewards was not significantly correlated with AUC during discounting of delayed punishment. d, Slope of percentage choice of the punished reward lever during DPDT and percentage choice of the delayed reward lever during delay discounting were not correlated. e, There was no differences in discounting curve slope between reward and punishment discounting. f, When animals were separated by sex, females demonstrated a higher slope for delayed reward than delayed punishment, indicating more rapid discounting of delayed rewards versus punishments. No task difference was observed in males. a, e, and f display mean ± SEM; b, c, and d display individual scores.
