Summary of group differences in model parameters for the temporal discounting DDM^a

Model parameter	Baseline		Magnitude effect
	Mdiff	dBF	Mdiff	dBF
Log(k)	2.26	77.9	−0.093	0.47
Drift rate coefficient	−0.365	0.061	0.020	2.73
Nondecision time	0.180	98.4	−0.0001	0.95
Boundary separation	−0.047	0.60	0.017	1.47
Starting point bias	−0.004	0.74	−0.017	0.26
Drift rate maximum	0.18	8.27	0.16	16.88

^aFor each parameter, we report mean posterior group differences (M_diff) and BFs (dBF) testing for directional effects on both the baseline parameter in the 100€ condition (left columns) and on the magnitude effect on each parameter (right columns). BFs < 0.33 reflect evidence for placebo < haloperidol, whereas BFs >3 reflect evidence for placebo > haloperidol. For details, see Statistical analyses.
