Parameter recovery analysis for all shift parameters using the DDMs (a, Log(k)shift; b, Drift rate coefficientshift; c, Nondecision timeshift; d, Boundary separationshift; e, Starting point biasshift; f, Drift rate maximumshift). Top row: Generating parameters vs. fitted parameters for each subject across ten simulations for haloperidol group (yellow) and placebo group (blue). Second row: True generating group level hyperparameter means (points) and Bottom row: standard deviations (points) and estimated 95% highest density intervals (lines) per fitted simulation.
