TABLE 3.

DIC values for the community and calibration samples indicating model fit for each model.

	DIC
Model	Community sample	Calibration sample
PVL-Delta-TD	–31461.25	–68394.44
PVL-Delta-TI	–31210.48	–68102.44
PVL-Decay-TD	–31245.04	–65478.23
PVL-Decay-TI	–30271.01	–63966.25

Values for the selected model are in boldface. Lower DIC values represent better fit compared to other models tested on the same data set. DIC values are group-level statistics. Delta = Delta learning rule; Decay = decay-reinforcement learning rule; TD = trial-dependent choice rule; TI = trial-independent choice rule.
