Dependent process model (DPM) results

(A) Goodness-of-fit measures for the four different dependent process models. AIC (dark) and BIC (light) scores for all single-parameter models, allowing either execution drift-rate (v_e; blue), braking drift-rate (v_b; green), execution boundary height (a; orange), or onset delay (tr; yellow) to vary across conditions. The model with the lowest score, in this case the braking drift modulation model, is preferred.

(B) Parameter estimates of the braking drift rate in stimulated and unstimulated trials in the beta (20 Hz) and gamma (70 Hz) sessions.

(C) Model predicted data (solid lines and circles) simulated with best-fit parameters from the v_b model overlaid on the average ± SEM empirical data (transparent circles and horizontal lines).
